In one or more embodiments of the present invention, the built-in CPU/processor of the controller (114) can execute an operating system and software that implements the e-picture function.

The controller (including components therein) (114) is powered by a battery and/or power supply (112). In one or more embodiments, the controller (114) is configured to detect and process input signals. For example, when an object touches the layer having at least one touch portion (104), a signal is transmitted to the controller (114) for detecting the input form and performing input processing. Further, the controller (114) is configured to store each stroke (in the form of a touch input or a digital marker) after performing the action on the e-picture (100) (see, for example, FIG. 6), for example, Permanent storage and / or volatile memory. In other words, the controller (114) is configured to store each stroke or action as it is generated in the active area of the front frame (102) of the e-picture device (100). In one or more embodiments of the invention, the controller (114) includes functionality to perform the methods as illustrated and described in Figures 6-8. Further, although the controller (114) has been described as a combination of hardware and software, the controller can be fully implemented in the hard body without departing from the scope of the invention.

In one embodiment of the invention, the e-map may include one or more external communication interfaces (116). These communication interfaces allow the e-Panel to interface with external components. These communication interfaces can implement any communication protocol, for example, Bluetooth, IEEE 802.11, USB, and the like. The invention is not limited to the aforementioned communication protocols.

In one or more embodiments of the present invention, the device (100) of FIG. 1 is a low power reflective device that only refreshes a screen with new display information or a user captures the device. Power is drawn from the battery/power supply (112) when information is entered. In other words, although the device (100) is "always activated" and is in a mode ready for detection input, the device is in a low power state. When an input is detected by the device (100) on the active area of the front frame (102), the e-picture device is configured to change from the low power state to an active state, and implement FIG. 6 and The method described in Figure 8.

In one or more embodiments of the present invention, the e-chart device can be considered to have some or all of the components on the e-map being in operation, ie accepting pens, touches, keyboard and LAN input, processing applications Actively when collecting/or saving data (and/or interpreting data) to memory. In the active state, the components of the e-graphics device draw energy from the controller (114). In contrast, the e-chart device can be considered a low power state (at least for a predetermined period of time) when no pen, touch, keyboard or LAN input is detected, but the device is still displayed on it. The last content displayed (or display no content). In the ready mode, the CPU processing is minimized, the scan rate of the fingertips and pen input is displayed, and the overall power consumption of the components in the e-picture device is reduced by, for example, at least 50%. Power consumption can be reduced by different amounts without departing from the invention. For example, only the battery and the controller can draw power in the ready mode, which reduces the overall power consumption of the e-picture device by 40% relative to the power consumption of the e-map device in its active mode. The management of the amount of power supplied to the components of the e-picture device and the frequency of the polling input are performed by the controller (114). In particular, the controller (114) can include an energy management program configured to control the status of various components of the e-picture device in accordance with whether the e-picture device is in a ready mode or in an active mode.

In order to compare the two states of the e-chart device, in one or more embodiments of the invention, when the reflective display is in the ready mode, input polling is performed at a low frequency, for example, the device can Perform 2 to 10 input scans in seconds. However, once an input is detected by the device, the device can be converted to an active state and the polling can be increased to a higher frequency, for example, 60 to 120 times per second, to capture that may occur on the reflective display. All the inputs. Other polling frequencies may be used in the active state and/or the ready mode without departing from the invention.

In one embodiment of the present invention, the term "low power state" is used to mean that the power consumption of the e-chart device in this state is relatively lower (or less) than that of the e-chart device in the active state. Power consumption.

Although not shown in FIG. 1, the e-flip device may include a camera for detecting certain input forms, such as an input of a gesture interpretation.

Those skilled in the art will appreciate that the size of the e-chart device is designed to mimic the dimensions of a conventional paper wall chart; however, the dimensions and dimensions of the reflective display device of Figure 1 can vary without departing from the scope of the present invention. For example, the additional dimensions may include 32 inches, an aspect ratio of 4:3 for a humanized size wall chart, and 55 inches or 60 inches for a larger cooperating surface. Even larger surfaces can change this aspect ratio to allow for more useful widths without increasing the unusable height, such as an aspect ratio of 9:16 for an 80 inch diagonal dimension.

Although the e-chart depicted in FIG. 1 has a series of components organized in a particular manner, those skilled in the art will appreciate the location of the various components in the e-chart, particularly the reflective display (106), having at least one touch The layer of the touch portion (104) and the optical electromagnetic layer (110) may be arranged in a different order without departing from the invention.

Specifically, FIGS. 2A to 2C illustrate top views of a digital marker having a cylindrical form (210). The top of the digital marker has an electronic eraser (202) and at least one button (206). In one or more embodiments of the invention, the button (206) is software programmable and, when pressed or otherwise activated, configured to transmit one or more electronic signals to the e-picture . For example, when the button (206) is pressed or otherwise activated, the button (206) can transmit a wireless signal that can be detected by the e-map. Those skilled in the art will appreciate that the button (206) can be hidden or built into the electronic eraser (202). Further, although only one button is illustrated in Figures 2A through 2C, the digital marker may contain more than one button, each of which may be separately programmed. In one or more embodiments, when the electronic eraser (202) is in contact with the e-picture, the e-picture is configured to remove or otherwise clear content from the corresponding locations of the reflective display . In other words, the electronic eraser (202) emulates the operation of a conventional eraser.

FIG. 2B illustrates a different direction of the digital marker or digitizer (ie, a side view of the 0 degree rotation of the cylinder), wherein the button (206) is located on a side of the electronic eraser (202), and Not at the bottom of the electronic eraser (202). Figure 2C depicts another top view of the digital marker wherein the cylinder is rotated 90 degrees. In Figure 2C, the button (not shown) is hidden from the perspective.

3A through 3C depict side views of the digital marker or digitizer in accordance with one or more embodiments of the present invention. In Figures 3A through 3C, the overall length of the cylindrical marker (210) of the digital marker can be seen. In Figure 3A, the electronic eraser (202) is depicted at the top of the digital marker. In addition, the tip (204) of the digital marker or digitizer is depicted at the bottom end of the cylinder (210). The tip (204) material can be selected such that the tip (204) is susceptible to sliding over the writing surface. Materials for the tip (204) may include, but are not limited to, high density polyethylene, hard felt, elastomer, polyoxymethylene, polyacetal or polyoxyethylene. Other materials may be used without departing from the invention.

In one or more embodiments of the invention, the tip (204) of the digital marker can be used to draw or write directly on the active area of the frame (102) prior to the e-frame device. In Figure 3B, the button (206) is shown on one side of the cylinder (210) of the digital marker. In Figure 3C, the tip (204) of the digital marker is shown to be thinner and sharper than the tips of Figures 3A and 3B. One of ordinary skill in the art will appreciate that the tip (204) of the digital marker is a hardware component that is replaceable and designed to emulate a pencil, pen, marker, stylus or any other variation. A suitable writing instrument for width and sharpness. In Figure 3C, the button is not shown.

Although Figures 3A through 3C illustrate the digital marker as a cylindrical shape, those skilled in the art will appreciate that the shape of the digital marker can have other forms without departing from the scope of the present invention.

As described above, the user of the e-map can create, display, store, modify, and share e-presentations. Each e presentation contains one or more pages organized in a sequential manner. The controller includes information to store the need to maintain the e-presentation and allows the user to interact with the e-presentation as described below. An example e demonstration is shown in Figure 4.

FIG. 4 illustrates an e-presentation (400) in accordance with one or more embodiments of the present invention. The e-presentation can include one or more pages (402, 404, 406, 408), each of which represents an electronic page of the e-map. Each page of the e-demo (400) corresponds to the content displayed on the e-picture device. In one or more embodiments of the present invention, the e-demo (400) illustrated in FIG. 4 may be stored in a memory or permanent storage associated with the e-picture device or stored in the e Demonstrate the backup to the cloud computing environment, or store it in any combination. For example, the e-demo can be stored in local permanent storage and stored in a cloud environment.

In one or more embodiments of the invention, the e-pages (402, 404, 406, 408) are all immediately linked when the e-presentation is populated. The links between the pages are represented by double-headed arrows in Figure 4. Specifically, the link between the page of the e-presentation and the metadata used to track the various information associated with the e-presentation is depicted in FIG.

In particular, in Figure 5, each e-presentation (500) can be associated with a selective owner (502). In one or more embodiments of the invention, the owner (502) may present the entity or device in which the e was originally created. In this case, the owner (502) can be represented by a device identification (ID) that identifies the device on which the e presentation was created. For example, when the e-demo (500) is created on the e-Panel device, the owner (502) field can be populated with the local ID of the e-map. Alternatively, the owner (502) field can be a body or group of individuals. In this case, the owner (502) can be represented by one or more user IDs. In one or more specific embodiments, although not shown, an e-presentation may also have rights associated with the presentation or with each page of the e-presentation. In particular, the permission to read/view/edit an e-presentation may be given by the owner (502) of the e-demo (500), or by the e-pad or other device designated as the owner of the e-demo Given by the user.

Moreover, as illustrated in FIG. 4 above, the e-presentation (500) may be comprised of one or more pages (eg, page 1 (504), page N (506)). Each page (504, 506) is then associated with the content (data) and the interpretation material. For example, as depicted in FIG. 5, the page (504) has a page identification (ID) (508), a state (510), a display ID (512), and sequence information (514). The page ID (508) uniquely identifies the page in the e presentation. The page ID (508) can be a number, a letter, a symbol, or any combination thereof. In one embodiment of the invention, each page can be associated with a state (510). In this particular embodiment, the page (504) state (510) can be an active or an inactive state, but is not limited thereto. The active state indicates that the page (504) is currently being displayed or written through the e-map or through another device (e.g., reference to Figure 10). The inactive state indicates that the page (504) is part of the e presentation, but is not currently being displayed (ie, the page is not displayed) or is being written. Those skilled in the art will appreciate that a page can be associated with other states without departing from the scope of the invention, such as, for example, an edit state in which the page is being edited offline, or the page is linked to the e Demo but offline or stored offline in permanent memory.

In one embodiment of the invention, each page can be associated with a display ID (512). In this particular embodiment, the display ID (512) associates the page (504) with a display device. For example, in the scenario in which the page (504) is displayed on the e-chart, the display ID may be the ID of the e-chart. In an alternate embodiment, assume that the page (504) is linked to one of the e-presentations that are currently being modified on the e-map, but not the active page of the e-demo. In this case, the page (504) can be shared with the second device over the network so that the owner of the second device can edit the page (504) (see, for example, Figures 9A through 9C, 10) . In this scenario, the display ID (512) associated with the page (504) is the ID of the second device on which the page (504) is being edited. Accordingly, the display ID (512) that is linked to one of the e-presentation pages (504) can be changed at any time. In one or more embodiments, there may be multiple display IDs (512), each corresponding to a device that is currently viewing the page (504). Further, in one or more embodiments, the display ID may also be specified only when the status of a page is active. When the page status is inactive, the display ID field in the e presentation structure may be null.

In one or more embodiments of the present invention, the sequence information (514) of a page (504) links the page (504) to other pages in the e presentation in a specific order and indicates an e-demo How these pages are flipped back and forth. Specifically, the e-chart device emulates the use of a conventional paper wall chart device in which a new page is obtained by flipping a current page over the wall chart device. In the conventional wall chart device, the pages are paged in an order, so the page cannot be skipped to obtain a special page of the e presentation. Similarly, with the e-pen chart device, each page (504) of the e-demo can be linked to at least one page before the page (504) in the e-demo and at least one page after the page (504). . In one or more embodiments of the present invention, the sequence information (514) may include at least the page before the page (504) and a page ID of the page after the page (504). Those skilled in the art will appreciate that the controller can facilitate jumping to the page out of order without departing from the scope of the present invention.

In one or more embodiments of the present invention, as illustrated in FIG. 5, the interpretation material associated with an e-demo can be populated and stored in a data structure when the e-demo is created and modified. . The data structure can then be stored locally in the e-pad device permanent storage or in a cloud computing environment. A specific example of how the material structure is populated is described in Figure 8 below.

Figure 6 is a flow chart showing one or more embodiments in accordance with the present invention. Although the various steps are presented and described in a sequence in this flowchart, those skilled in the art, having the benefit of the present disclosure, will appreciate that some or all of the steps can be performed in a different order. They may be combined or omitted, or some or all of the steps may be performed in parallel. Moreover, the steps can be performed in an active or passive manner. For example, in accordance with one or more embodiments of the present invention, some steps may be performed in a polling manner or interrupted.

In step 602, the e-chart device is in display ready mode. As described above, the e-chart device is always "on" and is therefore ready for use when a user walks toward the device or provides another form of input detected by the device (step 604). Specifically, in the ready mode (or basic state), the e-chart device performs input polling at a low frequency or input scan rate. In this mode, the display area of the e-picture device can contain images from the time it was most fully activated. When an input is detected, the device changes from the ready mode to the active state. For example, in one or more embodiments of the present invention, when an input is sensed by the electromagnetic panel, a signal is transmitted to a controller CPU, which executes the energy management software to "wake up" some Or all components and set them in Active Mode. The same procedure is also performed when a signal is detected through the GUI, touch input, or a "wake on LAN" input.

The input detected by the e-picture device in step 604 may be a wireless input provided by pressing a button, such as a Bluetooth input, a radio frequency input or other wireless network signal, a digital marker input, a touch Touch input, gesture input, or any other suitable form of input. Based on the detected input form, a specific action can be performed by the e-picture device. Thus, once the input is detected, the determination is made as a touch input or a gesture input (step 606). If the detected input is a user gesture, the e-chart device can be configured to perform gesture detection or launch a user interface (UI) component (step 608). For all other input forms, a suitable action can be performed by the e-picture device (step 610). For example, when the detected input is not a touch or a gesture input, but a wireless signal, for example, when the button is pressed on the digital marker, the corresponding external event can be started (step 610). For example, in step 610, when the input is a Bluetooth signal, the e-chart device can be configured to activate a peripheral device or an external Bluetooth receiver. In one or more embodiments of the present invention, the external event input may also be a proximity sensor, a motion sensor, a sound sensor that detects sound above a special decibel threshold, etc. Detecting the presence of one or more persons near or adjacent to the e-picture device. For example, the proximity sensor can include an ultrasonic sensor or an infrared sensor. In still another embodiment of the present invention, when the detected input is a stroke of a pen using a digital marker or a digitizer, the e-chart device can be configured to detect a path of the digital marker tip And converting the action into a display of simulated ink strokes (step 612). Accordingly, the specific actions performed by the e-map can vary depending on the form of input received.

When the detection input is a gesture or a touch input, the activated component can display the data on the display area, scroll the page, enlarge the displayed content, or perform any other suitable action to respond to the touch/ Gesture input. In one or more embodiments of the present invention, after performing an action of responding to an input detection, the e-chart device returns to the basic state of the "ready mode". In one or more embodiments, in this mode, the e-chart device continues to display an image without any power used by the bistable reflective display assembly of the device. Examples of such operational forms that can be implemented are described below in Figures 7A through 7E.

Specifically, in one or more embodiments of the present invention, FIG. 7A illustrates an example front frame (102) of an e-chart device. The front frame (102) emulates a screen and has an area that accepts at least two input forms: a touch and a digital marker. When one of the aforementioned input forms is detected, for example, an e-demo (700) is created and displayed in the active area or display area of the layer having at least one touch portion (104). Specifically, the e-demo (700) is created when a user approaches an e-picture device in ready mode and provides an input. The creation of the e-presentation may include generating and populating the data and interpretation data as depicted in FIG. In Figure 7A, the display area is blank. In Figure 7B, an example input using a digital marker (210) on the active area of the e-picture device is illustrated. Specifically, in FIG. 7B, when the tip of the digital marker or digitizer (210) is pressed on the active area of the e-picture device, the path of the digital marker (210) is detected. The software of the e-picture device is converted to an analog ink stroke (702), which is displayed on a first page of the e-demo (700). FIG. 7C illustrates at least one embodiment in which the displayed stroke image is retained on the e-picture device without any power expense of the reflective display assembly of the e-picture device. In one or more embodiments of the invention, the reflective display displays the latest information from the input to the e-picture and does not change until a new input is received by the controller.

In Figure 7D, a touch input (704) is detected by the e-picture device. In the illustrated example, a user touches the display screen (706) and in one or more embodiments, moves his/her fingertips in an upward motion (indicated by an upward pointing arrow), Causes the current page (708) to turn pages to start the new page of the e demo (700). Those skilled in the art will appreciate that in addition to or in lieu of the manner in which the touch display is depicted as illustrated by the example in FIG. 7D, a gesture input can also be used to cause a page to be paged. For example, a visual gesture that can be detected by the camera and interpreted as a page flip (eg, the hand moves with a special path without touching the e-picture) can cause the software to interpret the flip gesture as a page flip. action. A page flip action causes the e demo to transition from one current page to another. In Figure 7E, a graphical user interface (GUI) (710) is displayed on the screen of the e-picture device. The graphical user interface (710) can be invoked by pressing a button on the digital marker, by a gesture, or by any other specified input. In one or more embodiments of the invention, the GUI (710) can be invoked from a list on an auxiliary screen, for example, the auxiliary screen is connected to a cloud server using a two-way communication channel. In one or more specific embodiments, a GUI (710) can be used to select a particular feature or to perform a selection action, such as, for example, sharing a current page of an e-present, selecting an eraser, changing a font, a style, or the display. The color of the line strokes and so on.

Figure 7F shows an example of an e presentation with a drawing. In one or more embodiments of the present invention, as depicted in FIG. 7F, the e-chart device may display a pencil skeleton map (712) to assist a user in creating an e-presentation. The pencil skeleton can provide a light color image, so a user can track the light pencil drawing with a marker at a later time to draw a predetermined object. For example, this feature can be used to create the illusion that the user department is rapidly creating artwork. While Figure 7F depicts a pencil skeleton of a flower, one of ordinary skill will appreciate that the pencil skeleton can depict any object, or more generally any form of assistance with writing or drawing. For example, the pencil skeleton can be a combination of light horizontal and vertical lines to emulate drawing paper or notebook paper.

Figure 8 is a flow chart showing one or more embodiments in accordance with the present invention. In particular, Figure 8 illustrates a flow diagram for creating and maintaining an e-presentation in accordance with one or more embodiments of the present invention. Although various steps are presented in this flowchart and are described in a sequence, it will be understood by those of ordinary skill in the art that Or some or all of the steps can be performed in parallel. Moreover, the steps can be performed in an active or passive manner. For example, in accordance with one or more embodiments of the present invention, some steps may be performed in a polling manner or interrupted. As an example, in accordance with one or more embodiments of the present invention, the determining step may not require a processor to process the instructions unless an interrupt is received to indicate that the condition exists. As another example, in accordance with one or more embodiments of the present invention, the determining step can be performed by performing a test, such as checking a data value to test whether the value is consistent with the test condition.

In step 800, the e demo is created and associated with a demo ID. In one or more embodiments of the invention, the presentation ID may be specified by an e-presentation server, or alternatively may be generated by the e-clause or in response to an input prompt for the user. The e-presentation server can be a remote server that is connected to the e-picture device via a network. The function and purpose of the e-presentation server are described below in FIG. The presentation ID can be a numeric ID, a letter ID, a symbol ID, or any combination thereof, and is configured to uniquely identify the e-presentation displayed on the e-graphics device. When an e demo is first created, it may not contain anything. Further, if the e-chart device does not receive any user input for a certain period of time, the e-chart device can be changed to the ready mode. In one embodiment of the invention, step 800 can be performed in the e-Panel device in a ready mode or an active mode.

In step 802, an input is detected by an e-picture device in the ready mode. In the ready mode, the device performs an input scan at a low frequency, such as twice per second. As described above, the input detected by the reflective display can be a touch input, a digital marker input, a proximity sensor input (eg, when a user approaches the e-picture device), Network signal or any other suitable form of input. As described above, when an input is detected, the device changes state from the ready mode to the active state. For example, in one or more embodiments of the present invention, when an input is sensed by the electromagnetic panel, a signal is transmitted to a controller CPU that executes the energy management software to "wake up" the Some or all of the components, and set it to "active mode." The same procedure is also performed when a signal is detected through the GUI, touch input, or input on a "local area wake up" input. Step 802 is also performed when the e-picture device is in active mode.

In step 804, an action is performed to return the input. For example, the corresponding action may be to activate one or more components of the e-picture device, convert the input stroke to display the rendered stroke image, display a GUI, share information with another device, and the like. In one or more embodiments of the invention, the device can recognize the tip width of the digital marker by various methods when the input is received through a digitizer on the surface of the device. For example, the electromagnetic plate can detect the tip width of the digital marker. Alternatively, the layer having at least one touch portion can be configured to detect the tip width of the digital marker. In yet another embodiment, a digital marker can transmit a signal to the device that includes information about the width of the tip. In one or more embodiments of the invention, the device can be configured to display a certain line segment width for the rendered stroke using information about the tip width associated with the received input.

In step 806, the data structure for storing the interpretation material associated with the e-presentation (as illustrated, for example, in FIG. 5) is populated with a page ID and a display ID . In addition, the state of the current page having the page ID is changed to boot. In one or more embodiments of the present invention, the data structure may be populated and stored locally (in memory associated with the e-picture device) or may be stored remotely, for example, Stored in an e-presentation server or cloud computing environment. If the data structure is stored locally, the data structure can be backed up (eg, mirrored) on a remote server or in the cloud computing environment. At this stage, various actions can be performed that result in writing or drawing on the current page. In step 808, an input leading to the display of the new page can be detected. For example, a touch input or gesture that causes a page to flip.

In step 810, when a second page is created as part of the e-presentation, the material structure is populated with sequential information, which links the first page to the new second page in the e-demo. In step 812, the new page of the e presentation can be assigned its own page ID (which is after the ID of the first page), and the display ID. In addition, the state of the first page is changed to be inactive, and the current page, that is, the state of the second page is changed to be active. In step 814, the input is received by the e-picture device.

In step 816, it is determined if the input received in step 814 is a page flip action. If a page flip action is detected, the method proceeds to step 808, and the data structure continues to be populated with a third page ID, and the sequence information for the second page is updated to reflect the link to the third page. This program can be repeated each time a flipping action is detected by the e flipchart device. Alternatively, if no page flip action is detected, then the program proceeds to step 818. In step 818, an action corresponding to the received input is performed. In one embodiment of the invention, since the e-picture device is not switched to "off", the program may not end (i.e., the different steps in Figure 8 may be repeated). More specifically, when the input is not detected for a predetermined time, the e-picture device returns to "Ready Mode" and waits for input (step 814).

9A through 9C are diagrams showing an example of the method described in the above Fig. 8 in accordance with one or more embodiments of the present invention. In Figure 9A, consider the context in which an e-draft device creates an e-demo. At some point after the e-presentation is created, it is assumed that a user walks to the e-chart device and provides input in the form of pressing a button on the digital marker or writing in a digital marker. Once the input is detected, the action associated with the input is interpreted and in this example results in content associated with the e-presentation first page (902). The first page (902) (i.e., the page on which the text is written) is displayed on the active area of the e-picture device in a white background manner. At this stage, the data structure (900) storing the interpretation data associated with the e-demo begins to be populated with the interpretation data. As depicted in FIG. 9A, the interpretation material associated with page 1 (902) includes an active state, a page ID of 1, and a display ID identifying the e-picture device. The owner ID of the e demo may also be the ID of the e flipchart device, or null for the purposes of this example. Those skilled in the art will appreciate that there is no sequence information for a single page e-presentation.

Now suppose that the user gestures or provides a touch input, the software of the e-picture device interprets it as a page flip action. As shown in FIG. 9B, a second page is added to the e-presentation, and the interpretation data for both page 1 (902) and page 2 (904) is updated/filled into the data structure (900). Specifically, the state of page 1 (902) becomes inactive because it is no longer the page being displayed. Further, the display ID field of page 1 (902) is updated to a null value. The sequence information is added to page 1 (902), which links the pages to the second page (904) in sequence. For page 2 (904), the active state is retained, the new page ID is specified, and the display ID is updated to the ID of the e-picture device. The sequence information for page 2 (904) is populated to reflect that page 2 (904) is linked to page 1 (902). More specifically, page 2 (904) is after page 1 (902). This sequence of information becomes important when a page flip action is performed. Specifically, during normal operation, since the e-picture device emulates a conventional paper wall chart, the page must be flipped in order (ie, for example, when using the page flip action, although multiple pages can be grouped It was flipped, but we can't jump from page 1 to page 4 without flipping page 2 and page 3.

Continuing with this example, Figure 9C depicts the interpretation material associated with the e-demo when the e-presentation is shared with other owners/devices to work together on the e-demo. In Figure 9C, a third page (906) is added to the e-demo. In this example, the third page is directly shared with another device (device 1) while the second page (904) is still displayed on the active area of the e-presentation device. The device 1 (not shown) can be any smart phone, tablet, laptop or desktop computer, smart/interactive whiteboard, or can display content and connect to the e-flip device or the shared e-presentation server (1002) Any other suitable device. Further, the device 1 can be connected to the e-picture device through a point-to-point or wired or wireless network, such as through the Internet or indirectly through a cloud server. Continuing with the data structure (900), the first page (902) remains inactive, and the second page (904) is updated to reflect its previous link to page 1 (902) and then to page 3 (906). In one or more embodiments of the present invention, the state of the third page is also active because even if it is not displayed on the e-picture device, it is being displayed on another device (ie, device 1) )on. Accordingly, the display ID of the third page (906) is device identification 1, which identifies device 1.

Those skilled in the art will appreciate that page 3 (906) of the e-presentation as described in Figure 9C above may be local (i.e., in the same room with other people viewing the e-presentation) or remotely (also That is, sharing the network connection of someone viewing the e-present on a remote device. Further, the information can be transmitted and received by the device 1 and the e-picture device in both directions (through a server configured to store and manage all e-demo files, or directly). Accordingly, all or a portion of the e-presentation created on the e-picture device can be shared and edited by a plurality of devices (all connected to the e-picture device or to an e-depresentation server). This allows for collaborative work with audience members who are not physically located in the room where the e-chart is located.

Figure 10 illustrates a system for sharing an e-dance created on an e-picture device in accordance with one or more embodiments of the present invention. Specifically, FIG. 10 illustrates an e-presentation server (1002) connected to the e-chart device (1006) through a network (1004), and an e-demonstration (1008) on the e-chart device (1006). Was created on. In one or more embodiments of the invention, the e-presentation server (1002) can be a remote server configured to store and manage the e-demo as a shared archive. For example, the e-presentation server can be a cloud computing server or any other suitable form of server. In this case, as depicted in FIG. 10, the e-presentation server includes a copy of the e-demo (1008). In one or more embodiments of the invention, the e-presentation server (1002) is configured to specify the e-demo-e presentation when it is created or displayed on the e-picture device display (1006) ID. All pages of an e demo are then associated with this e demo ID. In addition, the e-presentation server (1002) is configured to perform the permissions of the e-presentation and can maintain and/or back up the data structure created for each e-demo (eg, refer to FIG. 5). The e-presentation server (1002) can also be configured to synchronize a shared e-demo based on multiple simultaneous inputs from other devices (e.g., 1007) connected to the same e-demo.

In a specific embodiment of the present invention, if a plurality of devices simultaneously edit an e-demo, when a particular device changes the e-demo, the device transmits an incremental update to the e-presentation server (1002). . In response to receiving the update, the e-presentation server updates a copy of its e-presentation and then transmits the incremental update to all other devices (in addition to the device that transmitted the incremental update).

Continuing with the discussion of FIG. 10, the network (1004) can be any wired or wireless network configured to facilitate two-way communication between the e-presentation server (1002) and the e-chart device, as well as directly facilitating the device Two-way communication between 1 (1007) and device 2 (1010). As noted above, the network (1004) can be the Internet or any other suitable network. Device 1 (1007) and device 2 (1010) may be local devices in the same room as the e-map device, or all may be remote devices connected to the e-picture device through the e-presentation server (1002). Device 1 (1007) and device 2 (1010) can be a tablet, a smart phone, a laptop, a desktop computer, a wearable device such as an interactive watch or a wristband, or any other suitable device. Alternatively, one or more of device 1 (1007) and device 2 (1010) may be other e-picture charts. The system of Figure 10 allows the user to view and work collaboratively on the e-presentation, which can be instantly updated by a remotely connected device. The following examples describe the concept of utilizing such components of Figure 10.

It is assumed that the device 1 (1007) is in the same physical location as the e-picture (1006), and the device 2 (1010) is a remote device. A reporter/user of the e-Panel device (1006) can invite viewer members to work collaboratively while editing or displaying the e-demo, and provide input in the form of writing or drawing to have been created and being rendered on the e-flip chart In the e demo on the device. In this case, the reporter/user can provide an input that causes device 2 (1010) to be granted permission to edit the e-presentation. In this case, the device 2 (1010) can connect to the e-presentation server through the network (1004), download the e-demo, and then edit the e simultaneously with the device 1 (1007) and the e-picture device (1006). Demonstration. When the device 2 (1010) finishes editing, the e presentation server can delete the device 2 display ID. The multiple pages of the e presentation can be shared individually, or the entire presentation of the e presentation can be shared using the system of FIG. Further, multiple pages of an e-Panel device can be edited in parallel, and the e-presentation server can be configured to synchronize the e-demo when editing is complete.

In an alternate embodiment, device 2 (1010) may display a GUI (1012) of various buttons having a plurality of different functions on its screen, one of which is a button having a page flip function. Using the GUI, device 2 (1010) can manipulate the content currently being displayed on the active area of the e-picture device without actual editing capabilities. In order for device 2 (1010) to manipulate the content displayed on the e-chart, device 2 (1010) must be connected to the e-chart device (1006) or to the e-presentation server (1002). The connection can be wireless or wired. In this case, the owner of the e-presentation can provide the device 2 (1010) GUI by providing an input permitting device 2's viewing rights but without editing rights.

Those skilled in the art will appreciate that the e-chart device can be used in any suitable environment, for example, those conventional paper wall charts are a traditionally useful environment. For example, the e-chart device can be used in a seminar room, classroom, conference room, or any other suitable environment. In one or more embodiments of the invention, the e-Panel device is designed to connect to the outside world using digital technologies such as network connections and to store content writing records that have been written on the device. Moreover, with the e-fender device of the present invention, the ability to create and store the e-demo (before it is presented to the viewer on the e-flip device) is available. For example, the e-chart device may have a removable memory on which the presentation may have been created and stored, and when the removable memory system is installed in the e-picture device, A pre-created e-demo can be displayed on the reflective display. The e-presentation created by the e-flip device can be stored, copied, shared, revised, transmitted, and managed using the information described above. In addition, since the e-chart device uses a reflective display, it emulates the look and feel of the conventional paper wall chart.

As discussed above, the present invention relates to linking or otherwise combining multiple interactive devices to create a multi-device workspace. Figures 10 through 20B illustrate various embodiments for creating and utilizing a multi-device workspace in accordance with one or more embodiments of the present invention.

Figure 11A illustrates a system in accordance with one or more embodiments of the present invention. The system includes a work area management system (1102) and one or more devices (device 1 (1106), device N (1108)) connected via a network (1104).

In one or more embodiments of the invention, the workspace management system (1102) can be any computing system (eg, refer to FIG. 21) configured to track and manage the multi-device workspace (not Show) the associated interpretation data. In one or more embodiments of the invention, the workspace management system (1102) can operate in a cloud computing environment. Specifically, the workspace management system (1102) can include a cloud storage for storing a user activity record (1110) (and according to FIG. 11B) and tracking one or more workspace devices (1112), each One has a display area to construct a portion of the multi-device workspace. In one or more embodiments of the present invention, the work area management system (1102) may store the work area record (1112) by storing the identifier of the interactive device (ie, with each work area) Associated interactive device). The user activity record (1110) and the work area record (1112) may be a data structure for storing information related to the user.

As described above, each device (device 1 (1106), device N (1108)) that is part of the multi-device work area includes a display area that forms part of the multi-device work area on which the content can be being shown. In one or more embodiments of the present invention, the device (device 1 (1106), device N (1108)) forming the multi-device work area is an interactive device on which a user can provide input. (For example, touching an input, entering through a digital marker or stylus, etc.) and viewing multiple content objects. Each device (device 1 (1106), device N (1108)) can include its own CPU, memory, display, network connection, and other hardware/software capabilities. The device (device 1 (1106), device N (1108)) may include, for example, a smart phone, a tablet, a desktop computer, a game device, an e-picture device (for example, refer to FIGS. 1 to 10), and interact with each other. A whiteboard, or any combination of devices from the aforementioned interactive device form.

Those skilled in the art will appreciate that other suitable interactive means including any such interactive device having functionality coupled to the network (1104) may be utilized without departing from the invention. Thus, for example, if the work area devices (device 1 (1106), device N (1108)) include four e-chart devices in a room, then the multi-device work area can be the entirety of each e-picture device The display area is formed. That is, the combined display area of each of the four e-Panel devices will be considered the multi-device workspace and can be used to render or view content items. Similarly, if the work area devices (device 1 (1106), device N (1108)) comprise a smart phone and three interactive tablets, then the combined display area of all four devices as a whole may be the multi-device work area. And on it, multiple content objects can be viewed/presented.

Those skilled in the art will appreciate that a multi-device work area can be formed using only a single interactive device. Further, those skilled in the art will appreciate that although each work area device has a separate display area, the display area of each work area device becomes part of a larger multi-device work area that is logged into a single user. All work area devices are linked to the display area of the other work area devices. Accordingly, from the perspective of the user, the multi-device work area can be regarded as a single display area although it constitutes a separate physical device. In other words, the user can interact with the multi-device workspace in a similar manner as the user interacts with a single display device.

In one or more embodiments of the present invention, the devices (device 1 (1106), device N (1108)) may be private devices owned by a user (eg, a smart phone belonging to a user) A public device provided in, for example, an office, a school, or any other public place where a plurality of users can access the devices, or a combination of private and public devices. In order to make the device part of the multi-device work area, in one or more embodiments of the invention, the same user can log into all of the devices.

The network (1104) through which the devices (device 1 (1106), device N (1108)) are connected to the work area management system (1102) may be a local area network (LAN), such as a wide area network of the Internet. Road (WAN), mobile network or any other suitable form of network.

FIG. 11B illustrates data that can be stored and/or tracked by the workspace management system of FIG. 11A in accordance with one or more embodiments of the present invention. More specifically, as shown in FIG. 11B, the work area management system can store one or more user activity records (1110) (described below). In addition, the workspace management system can also track devices (1106, 1108) associated with a given workspace (1114). The work area records (1112) may include an identifier for each device (device 1 (1106), device N (1108)) or may be used to track the formation (or as part of) the multi-device work area. Any other suitable information for the device.

Returning to the user activity records, in one or more embodiments of the present invention, the user activity record (1110) may be any data structure such as a table, an array, a linked list, etc., The configuration is configured to store data that identifies a common user logged into the workspace devices that make up the multi-device workspace. Specifically, in one or more embodiments of the present invention, the user activity record may store a virtual canvas ID (1116), a user login credential (1118), device information (1120), and the virtual canvas. The last state (1122) and the record of the user login activity (1124). Each of these pieces of information is described below.

In one or more embodiments of the invention, the virtual canvas ID (1116) uniquely identifies a virtual canvas. In one embodiment of the invention, an absolute object represents a content item that can be selected and displayed in the multi-device workspace. The content object can contain text and/or image material. In one or more embodiments of the present invention, the virtual canvas may be a file, and the content object associated with the file may be text and/or image material contained in the file. The file in its entirety (including all the material in the file) is considered to be the virtual canvas. For example, an e-presentation depicted on one of the e-Panel devices described above in Figures 1 through 10 is a file that may be referred to herein as a virtual canvas (1116). The content object within the virtual canvas may contain portions of the archive. For example, the content item can be part of the textual material from the file or one or more images contained in the file. Using the e-patch instance, the content object can be the ones that are presented for the e-map.

In one or more embodiments of the invention, the content items can be grouped together to form a group of content objects. The set of content objects may only be portions of the virtual canvas (1116) having text or image forms that are grouped together for display on the multi-device workspace. For example, if the virtual canvas (1116) is an e-presentation with a page, an instance of a content object group in the virtual canvas may be text and/or image data forming one or more pages of the e-demo. . When the virtual canvas is an arbitrary file, the content object group may be a paragraph, a sentence, one or more drawings, or other text/image data groups that can be selected and displayed on a portion of the multi-device workspace. Those skilled in the art will appreciate that the complexity of the group of content objects may be in the form of content objects of the virtual canvas. For example, if the content objects are logically grouped into pages, the content object group can be one or more pages. However, for example, if the content items are brainstorming notes, the content object group can be a particular phrase or text in the notes. Further, those skilled in the art will appreciate that while a given virtual canvas may contain an initial collection of content object groups (eg, pages), such content objects within a given virtual canvas may be at any point in time. Regrouped. For example, a user can create multiple content object groups from content objects on a single page within the virtual canvas. Alternatively, the user can create a group of content objects that span multiple pages. The above examples are not intended to limit the scope of the invention.

Continuing with the discussion of FIG. 11B, in one embodiment of the present invention, the user login credentials (1118) stored in the user activity record (1110) may include one or more forms of user authentication information that are available. To identify the user. For example, the user login credentials (1118) can be a username/password pair, biometric data, radio frequency identifier, Bluetooth identifier, near field communication (NFC) tag ID, or any other unique identifier. Or any combination of the above user login credentials. As described above, the same user is logged into each workspace device to make the workspace device part of the multi-device workspace. However, user login may be performed in different ways on each workspace device. For example, a user may log in with a username/password pair on a first workspace device and log into a second workspace device using an optical logo. Alternatively, as described below in Figures 12 through 17, the same login method can be used to log into all of the multi-work area devices. Because the workspace management system tracks user activity in the user activity record (1110), each different login form is identified as the same user. Further, the user login activity (1124) stored as part of the user activity record (1110) is used to track the device that the user is logged into, the timestamp when the login occurred, and the login of each workspace device. The record of the login method. In one embodiment of the invention, the user activity record may only track whether the user successfully logged into a known device without recording the particular credentials that the user used to log into the device.

Continuing with the discussion of FIG. 11B, in one embodiment of the invention, the device information (1120) may contain information for the location of each workspace device. Location information can be obtained and stored in the user activity record using GPS information (for work area devices equipped with this function). Location information can be location information. The location of the workspace device stored as one of the device information (1120) may be a city, a building, a room, or any other geographic information at any complexity. The location information of the work area devices can be obtained from an auxiliary user device for logging into the work area devices. For example, in one or more embodiments of the present invention, a user can log into the workspace device using a personal smart phone encoded with NFC tag or equipped with Bluetooth Low Energy (BLE). . In this case, the location information of the work area devices can be obtained from the user's smart phone, which is an auxiliary device for identifying the user and logging into the work area devices. In another embodiment of the invention, the user can be prompted to provide a location of a known device, and then the workspace management system can store the information in the workspace management system.

The device information may include, but is not limited to, the size of the display on the device, the size of the display, the orientation of the device (eg, straight, horizontal, etc.) and the display resolution of the device.

In one embodiment of the invention, the user record includes a device ID (which uniquely identifies the device). In this case, the device ID is also associated with a device record (not shown) that can be located using the device ID. The device record can include the device information (1120) described above.

In one or more embodiments of the invention, the final state of the virtual canvas (1122) represents the last displayed state of the content items displayed in the multi-device workspace. In other words, the final state of the virtual canvas (1122) represents that the multi-device operates across the plurality of workspaces immediately before the user logs out of one or more of the devices that make up the multi-device workspace. The display status of the data (content items) seen by the device. Thus, by identifying the user at the user's logout device, the workspace management system can capture the last state of the multi-device workspace in which the user is working. In one embodiment of the invention, the user may automatically log out of one or more devices of the multi-device workspace after a predetermined inactivity time has expired in the multi-device workspace.

12 through 17 illustrate an example in which a user logs into a plurality of workspace devices to create (or form) a multi-device workspace. This example is not intended to limit the invention. Returning to Fig. 12, in Fig. 12, an auxiliary device (1200) (i.e., a user smart phone) is used to log into a first device (1202). In the particular embodiment depicted in Figure 12, the user utilizes the auxiliary device (1200) to log in to the first device (1202) of the four devices, the auxiliary device (1200) having NFC capability. Specifically, the user's smart phone (1200) encodes an NFC tag, and the first work area device (1202) has a near field communication transmitter/receiver that transmits a signal that detects the presence of the NFC tag. (1204), decode it, and load the user's credentials into the device (1202). In one or more embodiments of the present invention, the user's credentials are temporarily loaded onto the first device (1202) for a predetermined period of time or until the user logs out (or is logged out) ) the device or the multi-device work area. In one or more embodiments of the present invention, once the first device (1202) is recognized by the work area management system, the work area management system identifies the first device in a multi-device work area. . Accordingly, the first device (1202) can be assigned a work area device ID 1 (1211) as shown in FIG. The designation of this content and the grouping of workspace devices are discussed in Figure 18 below.

In one embodiment of the invention, the work area device ID uniquely identifies a device within a given work area. Further, once the work area device is assigned to a given device, the work area device ID can be temporarily displayed on the work area device (eg, refer to FIG. 17) to provide the user with information about which one to place. The workspace device ID specifies a visual indication to each workspace device.

Figure 13 is a continuation of Figure 12 in which the user logs into a second device (1206) using the same NFC capabilities described above. The second device (1206) transmits a signal (1207) that detects the presence of the NFC tag on the user's accessory device (1200), decodes it, and loads the user's credentials into the second device. (1206). As explained above, the second device (1206) is identified by the work area management system as part of the multi-device work area and is designated as the work area device ID2 (1213).

The program logged into the third device (1208) continues in Figure 14. The user's auxiliary device (1200) is used to log into the third device (1208) using the NFC capability (1209). As explained above, the third device (1208) is identified by the work area management system as part of the multi-device work area and designated work area device ID 3 (1215).

In Figure 15, the user logs into the fourth device (1210), and after successful login, the fourth device is associated with the multi-device workspace containing the three other devices (1202, 1206, 1208) contact. Finally, as shown in FIG. 16, the fourth device (1210) is assigned the work device ID 4 (1217).

Figure 16 shows that all four workspace devices (1202, 1206, 1208, 1210) are logged in with the user's credentials, each of which has been assigned a workspace device ID. The designation of the work area device IDs is tracked by the work area management system, for example, in the work area records (1112). As discussed in detail below in Figures 18 and 19, in one or more embodiments of the present invention, the workspace device ID is assigned based on the last previously known settings that the user has performed, even if It has more or fewer devices at different locations and even if it is compared to current multi-device workspace settings. Additionally, the work area device ID can be specified based on the location of the work area devices and the time stamp of the login of one work area device relative to the other work area device. As shown in FIG. 16, the auxiliary device (1200) of the user previously used to log in or transmit the user's credentials to the workspace devices (1202, 1206, 1208, 1210) may have information on their display. Information about such devices (1222, 1224, 1226, 1228) with such credentials or login information has been transmitted.

In one or more embodiments of the present invention, the user's auxiliary device (1200) may also be an auxiliary control device having a GUI as described in FIG. 10 above. The user can use the touch input (1220), for example, to control one or more displays of the workspace devices to which the user is logged. For example, in one or more embodiments of the present invention, the content item(s), the content item group(s), or the content pattern may be displayed on the user's auxiliary device (1200). When using his or her fingertips (1220), the user can select which of the content object(s) from the virtual canvas to be displayed by using the GUI on the auxiliary device (1200). On each of the workspace devices.

Alternatively, in one or more embodiments of the present invention, the auxiliary device (1200) may also be a work area device having a display area, together with the devices 1202, 1206, 1208, and 1210. The screen/area is displayed as part of the multi-device workspace.

Figure 17 is a diagram showing a similar multi-device work area as described in Figure 16 above, wherein the user logs into the four boards in a sequence from left to right different from Figure 16. Figure 17 illustrates that the user using the auxiliary device (1200) can align the order of the work area device IDs to correspond to the left-to-right order of the entities of the devices. Specifically, in FIG. 17, the work area management system has updated its record to reflect that the fourth registration device (1206) is located to the right of the first registration device (1202), and the third registration device (1208) is located to the right of the fourth registration device (1206), and the second registration device (12010) is located to the right of the third registration device (1208). Using this information, the workspace management system will allow the user to utilize the GUI operations to transfer content objects to the intended device, such as the operation of "delivering this content to the device on the left side."

Those skilled in the art will appreciate that other login methods can be used to log in to each workspace device. For example, in one or more embodiments of the present invention, the user can log into the work area devices using another auxiliary device, such as a USB key, a username/password pair, and an optical A logo, NFC token, radio frequency ID, Bluetooth ID, or a combination of one or more of these methods. For example, an optical logo having the user's login credentials can be generated and displayed on the user's auxiliary device and scanned by the camera of each of the work area devices to read, obtain, and Apply credentials such as the user to log in to the devices. In another example, an optical indicia can be displayed on the work area (or a portion thereof). The optical signature can then be read by an auxiliary device of the user. The accessory device can decode the optical tag to retrieve connection information that will cause the accessory device to provide user credentials to one or more workspace devices. Further, those skilled in the art will appreciate that the data structure discussed in Figure 11B above will be populated when the user logs into each of the workspace devices in Figures 12 through 17. That is, for each login, the timestamp of the login, the device location, the workspace device ID, etc. will all be stored in the user activity record as described above, so the workspace management system The workspace devices can be tracked and managed and interacted with by users of the workspace devices.

Figure 18 is a flow chart showing one or more embodiments in accordance with the present invention. Specifically, Figure 18 illustrates a procedure for creating a multi-device workspace. In step 1802, a user logs into a device. This device is referred to as a work area device even if it is the only device that the user is logged into. Based on the user's login, the workspace management system can identify the user, and the user's user activity record is obtained in step 1804. At this stage, the user activity record is checked to determine if there is a previous login profile in the user login activity stored in the user activity record (step 1806). When the previous login data does not exist in the user activity record, this indicates that the workspace management system user may be creating a new multi-device workspace. Accordingly, the process proceeds to step 1812 where a new multi-device workspace is created and the device is labeled as the first device in the new multi-device workspace.

Returning to step 1806, when the previous login data is present in the user activity record (step 1806), the user activity record is checked to determine whether the latest login to the device in step 1802 has occurred with the most recent previous The same location where the device is logged in (step 1808). In one or more embodiments of the invention, an identical location may be of any suitable level of complexity. For example, the login step 1802 can be performed on a device that is located in the same geographic location as the recent previous user logged into another device. The same geographic location can be the same room, the same building, the same program, and the like. Furthermore, the work area devices can be located at the same location without physically adjacent to each other.

Returning to step 1808, if the device login is in the same location as the most recent previous login, then a second decision is made as to whether the login to step 1802 occurred within the predetermined time period (step 1810). In other words, the timestamp of the most recent previous login to a workspace device is compared to the timestamp of the login that occurred in step 1802. If the login occurs during a predetermined period of time, then the next consecutive number is assigned to the device that the user entered in step 1802. In other words, the workspace management system uses the location and time of the login as two conditions by which the user is determined to wish to create a multi-device workspace. The process then proceeds to step 1814 where the device is associated with an existing work area and the next consecutive number (ie, work area device ID) is assigned to the work area (eg, reference to Figures 12 through 17) ). Those skilled in the art will appreciate that the present invention is not limited to determining when to create a location and time for login of a multi-device workspace, and other suitable conditions may be used to make the determination. For example, the user may include some preset conditions in the user activity profile to indicate when the workspace management system creates a multi-device workspace. Further, in one embodiment of the invention, only the time of use (e.g., step 1810) determines if a known device is part of the work area. In this particular embodiment, the geographic location is not required and/or may be unknown (or available).

Continuing with Figure 18, when the location of the workspace device from the previous user login and the current user login or the time of logging into the workspace device does not meet the conditions set by the workspace management system (step 1808 or 1810) If the result is "NO", then the workspace management system assumes that the device that the user logged in in step 1802 is part of the new workspace and specifies the first number of the device in the new multi-device workspace (step 1812) And the program terminates.

The above procedure describes how to assign unique identifiers and consecutive numbers to multiple workspace devices that form a multi-device workspace. In one or more embodiments of the invention, a plurality of workspace devices may be grouped together by the workspace management system. When a group of multiple devices is connected together and the system has used the procedure of FIG. 18 to identify which device is the first, second, and subsequent devices, the user only needs to interact with a single device in the group to utilize The content item fills any of the working devices.

In one embodiment of the invention, steps 1802, 1804, 1806, and 1812 or steps 1802, 1804, 1806, 1808, and/or 1810 and 1812 are implemented to create a new multi-device workspace that includes a single device. . Further, in one embodiment of the invention, steps 1802, 1804, 1806, 1808, 1810, and 1814 can be implemented to add any number of other devices to the multi-device workspace. In this method, you can dynamically create a multi-device workspace.

The program in Fig. 19 can be implemented after a multi-device work area (having one or more devices) has been created.

Figure 19 is a flow chart showing the display of content in a multi-device workspace in accordance with one or more embodiments of the present invention. In step 1902, a determination is made as to whether there is content for the new device in the multi-device workspace. In particular, in one or more embodiments of the present invention, after the multi-device workspace has been created, the workspace management system determines whether the user generated content objects in a previous multi-device workspace session ( For example, the user logs in and adds, deletes, and/or modifies the last time of the content item(s) in the virtual canvas. More specifically, the work area management system can analyze the user's (these) user activity records (ie, the user who created the multi-device workspace) to determine whether there is a final state of the virtual canvas (reference) Figure 11B, 1122). If the last state of the virtual canvas does not exist, the program proceeds to step 1904. Alternatively, if there is a final state of the virtual canvas, then the program proceeds to step 1906. In one embodiment of the invention, even if there is a final state of the virtual canvas, the user may choose to proceed to step 1904 to create a new virtual canvas instead of proceeding to step 1906.

In another embodiment of the invention, the determination at step 1902 is based on whether one or more content items are automatically displayed in the multi-device workspace. If a content item is displayed, the program proceeds to step 1906.

In step 1904, all of the display areas of the workspace devices may be blank until the user generates content items during the current multi-device workspace session.

The content items displayed in the multi-device workspace are selected in step 1906. In one embodiment of the invention, the selection of the display content objects results in the selection of a virtual canvas, and the selected content object is a portion thereof. In another embodiment of the invention, step 1906 relates to the selection of a virtual canvas rather than the selection of individual content objects (or groups of content objects).

Continuing with the discussion of step 1906. For example, the selection of the display content item can include obtaining the last displayed state of the virtual canvas. In another embodiment of the invention, the interpretation material associated with the virtual canvas can be used to select a content item for display. For example, the virtual canvas can be associated with information related to its location or time when a user logs in. Specifically, a user can have a document for a meeting, the meeting is scheduled for a special date/time on the user calendar, and the user can store the following preset/pre-configured options: When he or she taps or logs in to a workspace device (preset) at the conference location, he or she wants a particular content item to be displayed. Therefore, instead of displaying the last display state of the virtual canvas at the time of login, the user can set a special calendar event, and when the calendar condition is satisfied, the special calendar condition triggers other content objects (for example, Said, from another file) is displayed on the multi-device workspace. In other words, the workspace device can display the content items spoken by the interpretation material. In one or more embodiments of the invention, the interpretation data can be stored in the user activity record.

Those skilled in the art will appreciate that other forms of interpretive material can be used to produce content objects without departing from the scope of the invention. For example, the interpretation data can be a calendar variable indicating when the user's preference indicates when the user taps or logs into a workspace device at a certain time or date, and then a special file will span The multi-device workspace is displayed. For example, Monday at 9:00 am for the user's weekly meeting in the office. When the user taps or attempts to log in to the conference room or the workspace device in his office at about 9:00 on Monday, the workspace management system can store the calendar variables and identify the virtual canvas as being generated. The content items (the user can select a particular content object group from the content items for display in the multi-device workspace) should be "Weekly Prepare Meeting Documents."

In yet another embodiment of the present invention, the work area management system can be configured to "learn" the type of use of the user over time. For example, if the user starts a day by logging into his office workspace device and is busy with "File x", then the user continues to draft the presentation in the company's conference room every Monday morning, and On Wednesday night, the user logged into the workspace device of the Rotary Club meeting room and presented some graphics. By analyzing the activity records of the user, the workspace management system can be configured to detect a continuation of the meeting on Monday. In this case, when the user logs in to the workspace device on Monday, the displayed first document (ie, the content objects generated for the virtual canvas) may be from the previous Monday. The continuation of work.

Continuing with FIG. 19, once the content object to be displayed is selected in step 1906, the workspace management system identifies the first workspace device, and the content device from the virtual canvas is displayed in the first workspace device (step 1908). . The determination in step 1908 can be performed using the work area device IDs assigned to the devices (e.g., with reference to Figures 12 through 17), which are portions of the multiple work areas generated using the program of Figure 18. . In other words, a sequence designation of the numbers for each of the work area devices in the multi-device work area is obtained and the first device is identified.

In step 1910, the user selects (or automatically selects by the workspace management system) at least a portion of the content objects in the virtual canvas (identified in step 1906) for display in the display area of the first device. on. In one or more embodiments of the present invention, the selection of content objects from the virtual canvas can be performed in a variety of ways for display on each workspace device. For example, the user's auxiliary device (eg, refer to FIG. 17) used by the user to log in to the workspace device can be used as a user interface to control the display of the content. The user can also see the entirety of the virtual canvas on the auxiliary device. In this case, the user can select various combinations of content items (i.e., form a plurality of content object groups) and indicate on which workspace device the selected content should be displayed. Alternatively, in one or more embodiments of the invention, the preset options can be pre-configured and stored to display the content item in the multi-device workspace. For example, when the workspace device is a common device having the same or similar display area in each device in the same geographic location (eg, an adjacent e-picture device), the content item from the virtual canvas may span the All of the workspace devices are evenly distributed, so that all of the files represented by the virtual canvas are displayed across the workspace devices. Alternatively, when the workspace device in the same multi-device workspace is a mix of public and private devices, content items from the virtual canvas can be mirrored onto each device, so each device displays such The same content object.

In yet another embodiment, the workspace management system can prompt the user to select the content items (or groups of content objects) that the user desires on each workspace device. For example, when logging in to a workspace device, the user may be prompted to select whether the user wants to display the last state of the virtual canvas, generate a new content object on a blank multi-device workspace, or use the storage. Special interpretations in the workspace management system to obtain content objects for display.

Upon selecting at least a portion of the virtual canvas for display on the first workspace device (step 1910), the user can select the display of the selected group of content objects on the first workspace device The degree of zooming (step 1912). In one or more embodiments of the present invention, the degree of zooming may be selected by the user based on the size of the display area of the first work area device. For example, if the user is busy with a file in his office and proceeds to share the file on an e-chart device having a relatively large display area in a conference room, the user can zoom in on the e-chart device. The content items are displayed. In one or more embodiments of the invention, the degree of zooming in the form of different work area devices may be pre-configured and stored in the user activity record. Alternatively, the preset zoom level of each workspace device can be the same.

Those skilled in the art will appreciate that other display features other than the degree of zooming may also be selected by the user. For example, the direction of the display (eg, horizontal or straight) is another display feature that can prompt the user to select before displaying the selected portion of the virtual canvas on the first workspace device.

In one embodiment of the invention, step 1912 is performed automatically by the work area management system.

In step 1914, the (e) selected content object and/or content object group from the portion of the virtual canvas is displayed on the first workspace device with a selected degree of zoom. In one embodiment of the invention, step 1914 involves transmitting the (e) selected content item and/or content item group to the appropriate workspace device. At this stage, a decision is made as to whether there are other devices in the multi-device work area (step 1916). If there are other devices, then the process returns to step 1910 to cause the user to select the group of content objects for the next device in the multi-device workspace. When there are no other devices in the multi-device workspace (step 1916), the program terminates.

Those skilled in the art will appreciate that while FIG. 19 discusses a procedure for selecting and displaying content for each device starting with the first device in the multi-device workspace, in an alternative embodiment of the present invention, Devices in a multi-device workspace can be filled with content items at the same time. For example, when the devices are to display the same content items (the devices are mirrored to each other), all of the devices in the multi-device workspace can be filled with the selected content items at the same time. In this case, the devices may display the same content items at different zoom levels and in different directions (depending on the size of the display area of each work area device) or display content items having the same display characteristics.

FIG. 20A illustrates an example of a display area of four devices (device 1, device 2, device 3, device 4) that displays content items from the virtual canvas 2000. In one or more embodiments of the present invention, the virtual canvas (2000) in FIG. 20A represents a virtual space of content from which a content object group (2002, 2004, 2006, 2008) can be selected. A display on each work area device for a multi-device work area. More specifically, all content from a file (including text and image material) is represented by the virtual canvas (2000) in Figure 20A. For example, this file can be a single page of e-demo (as described in Figure 4 above) or a single page of notes. In one or more embodiments of the invention, each of the groups of content objects selected and displayed for each device constructs a portion of the virtual canvas. Each selection portion is part of a single page, or multiple portions of multiple pages when the content from a full archive spans the virtual representation of Figure 20A

Further, in the example of FIG. 20A, devices 1, 3, and 4 have similar display areas, and thus the selected content object groups can be displayed in the same zoom level and in the same direction. In addition, device 2 has different display areas as compared to such other devices, and thus the selected content object group (2008) can be displayed with display characteristics different from devices 1, 3 and 4.

In one or more embodiments of the present invention, the "position" of the devices illustrated in FIG. 20A may be determined by the x and y quadrants of the upper left corner of the display of each device, and the degree of zooming may be from 100% zoom is determined. The x, y coordinates of the display of each workspace device can be stored in the workspace device data structure of Figure 11B.

As can be seen from the example of FIG. 20A, the group of content objects (2002, 2004, 2006, 2008) displayed on each workspace device can constitute a plurality of non-contiguous portions of the virtual canvas. Further, portions of the virtual canvas may not be selected for display on any of the devices of the multi-device workspace.

Figure 20B shows the same virtual canvas (2000) as in Figure 20A. In FIG. 20B, the content object groups (2010, 2012, 2014, 2016) displayed on each of the four devices have a virtual canvas (2000) in its entirety (presented by the virtual canvas) Displayed in all the contents of the file). More specifically, the content object groups of the virtual canvas (2000) are displayed as contiguous portions of the virtual canvas (2000). Thus, in Figure 20B a single file can be evenly distributed across the multi-device workspace, with each of the four devices displaying a different group of content objects (2010, 2012, 2014, 2016) in an adjacency manner. For example, in the example of the representation of FIG. 20B, the file represented by the virtual canvas has four pages, and the page 1 is displayed on the device 1, the page 2 is displayed on the device 2, and the page 3 is displayed on the device 3. Page 4 is displayed on device 4. Those skilled in the art will appreciate that the virtual canvas content can be evenly distributed across the entire multi-device workspace regardless of the number of pages or any other configuration of the virtual canvas. The virtual canvas is evenly distributed across the work area devices such that each work area device displays a portion of the virtual canvas in an abutting manner.

The following examples are described to illustrate various applications of the various embodiments of the invention and are not intended to limit the scope of the invention.

Consider a situation in which a user previously worked on devices A and B. After a period of time, the user logs into the device C using the user's smart phone. A determination is then made as to whether the new device should be added to an existing work area containing one of devices A and B. If the decision is affirmative (e.g., the determinations in steps 1808 and 1810 are both "yes"), then device C will be considered a third device of the existing multi-device workspace. Alternatively, if the decision is negative (e.g., the determination in steps 1808 and/or 1810 is "NO"), then device C will be considered the first device of the new multi-device workspace.

In another example, assuming that a pair of devices is part of a multi-device work area, the multi-device work area contains only two devices. Device A shows the layout of a house, while Device B displays other content. Assume that the user logs out of the first multi-device workspace and then logs into a third device (device D) that is smaller than devices A and B. In this example, it is assumed that device D becomes the first device in the new multi-device work area. Further, assume that for this example, the user's existing virtual canvas is selected for display in the new multi-device workspace. Because the display area of device D is smaller than the display area of devices A and B, the work area management system automatically selects a subset of the virtual canvas for display on device D. Accordingly, in this example, only a portion of the house layout is displayed on device D. In another embodiment, the workspace management system does not specify a subset of the virtual canvas to display and leaves this decision to device D or the user.

In another example, assuming that a pair of devices is part of a multi-device work area, the multi-device work area contains only two devices. Device A shows the layout of a house, while Device B displays other content, both of which are oriented in a straight direction. It is assumed that the user logs out of the first multi-device work area and then logs into a third device (device D) that is smaller than devices A and B, where device D is in the horizontal direction. In this example, it is assumed that device D becomes the first device in a new multi-device workspace. Further, assume that for this example, the user's existing virtual canvas is selected for display in the new multi-device workspace. Because the display area size of the device D is smaller than the display area of the devices A and B, and because the direction of the new multi-device work area is different from the existing multi-device work area, the work area management system automatically selects one of the virtual canvases. The subset is displayed on device D. The selection of the portion of the virtual canvas to be displayed takes into account both the size and orientation of the device D. In another embodiment, the workspace management system does not specify a subset of the virtual canvas to display and leaves this decision to device D or the user.
