Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Additionally, the steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions and, although a logical order is illustrated in the flow charts, in some cases, the steps illustrated or described may be performed in an order different than here.
Fig. 1 shows a simplified usage state of an electronic reading device in a non-draft mode according to an embodiment of the present invention. In fig. 1, the electronic reading device 1 comprises a processor 10, a memory 11 in communication with the processor 10 and a display 13 with an infrared touch screen, a user interface unit.
Wherein the memory 11 is used for storing digital works for reading by users. A display 13 in communication with the processor 10 is used to present the digital work stored by the memory 11 as directed by the processor 10. The user interface unit may further include a touch sensitive component (not shown) integrally constructed with the touch screen display, an external physical keyboard (not shown), a home button (also called a key) 14, a draft button 15, a dictation button 16, and other similar keys. The touch sensing component and the external physical keyboard which are used as the user interface unit are used for receiving the instruction of the user and the draft information input by the user.
Physical buttons (e.g., draft button 15 and dictation button 16 in fig. 2, 4, and 5) are disposed in an opening of the electronic reader housing near the display 13. Virtual keys (e.g., reference numeral 15 in fig. 3, etc.) are provided near a display area for presenting the digital work stored by the memory 11 according to the instructions of the processor 10.
When detecting that a user inputs information through the infrared touch screen, the processor 10 determines whether a contact body (for example, the pen 20 in fig. 2 and 3) for contacting with the infrared touch screen currently contacts with the infrared touch screen over a preset area threshold, if the determination result is that the contact body is not greater than the preset area threshold (in the case of fig. 2), the current contact operation of the contact body with the infrared touch screen is a writing operation, and determines content to be input by the user according to the contact operation of the contact body. On the contrary, if the determination result is greater than the preset area threshold (in the case of fig. 3), the current contact operation between the contact body and the infrared touch screen is an erasing operation and the content displayed at the contact position of the contact body is erased.
How to calculate the contact area of the contact body and the infrared touch screen belongs to the prior art, and a person skilled in the art can understand the calculation in combination with the chinese patent applications CN201080015160.3, CN201210182655.6, etc. Both of these patent applications are incorporated herein by reference in their entirety.
Fig. 2 shows a simplified diagram of a user entering a usage state in a draft mode of an electronic reading device in accordance with an embodiment of the present invention. And fig. 3 shows a simplified usage state diagram of the electronic reading device in the draft mode with the user performing an erasing operation according to an embodiment of the present invention.
According to the technical scheme, a user can conveniently use a thin pen point (20A) of the pen 20 to write contents on a screen to input contents which the user desires to input, when the pen is turned upside down, a large head (20B) of the pen contacts the screen (according to the principle of an infrared screen, the pen can be close to the screen without contacting the screen, and the touch refers to contact or approach), and then the processor 10 judges that the user desires to execute an erasing operation, so that the erasing processing is executed. As shown in FIG. 3, the pen 20B has almost erased the last n in the formula. Therefore, the user can directly use the habit of writing and erasing the writing to input and erase the writing on the electronic reading device, thereby greatly improving the user friendliness and facilitating the input of the user. On the basis of this innovative improvement, the invention can very well support the following improvements which will be further explained later and facilitate the draft of the user.
When the user presses or touches the physical button 15 or the virtual button 15, the user interface unit receives the first user instruction on the draft to be drafted, and transmits the first user instruction on the draft to the processor 10.
In fig. 1, the electronic reading device 1 does not receive a first user instruction of the user about to draft, and the device is in the non-draft mode. At this time, the electronic reading device 1 displays the digital work for the user to read in the original screen display area. The original screen display area may be any size of display area. But in general, the original screen display area is preferably full screen or nearly full screen to facilitate the reader's reading as much as possible.
Fig. 11 shows a flowchart of the electronic reading device 1 according to the embodiment of the present invention accepting and processing the first user instruction of the user about to draft.
What processes are to be performed when a first user instruction about draft to be drafted by the user is received is described below with reference to fig. 2 and 11.
In step S110, the user interface unit receives a first user instruction about draft to be drafted, which is input by a user.
In the present embodiment, the user may issue the first user instruction by pressing or touching the draft button 15. In other examples, the user may also issue the first user instruction by touching a virtual key (e.g., virtual key 15 in fig. 3 and 8) or a voice command. Both keys 15 and 16 are thus optional.
In step S112, the processor 10 instructs the display 13 to reduce the display area for presenting the digital work from the original screen display area to the first display area (gray area indicated by reference numeral 21 in fig. 2) after the key (also referred to as button) 15 of the user interface unit receives the first user instruction about the draft to be drafted.
At step S113, the processor 10 opens the second display region so that the user can input/erase any contents through the user interface unit in a manual writing manner or in a keyboard input manner in the second display region 22 not overlapping with the first display region 21 of the display 13. The second display region does not overlap with the first display region. Preferably, the second display area is located in the display area vacated by the reduction of the first display area.
Here, the input through the user interface unit in the manual writing manner means that a pattern is drawn with a finger or a pen on a touch screen of the electronic reading device 1 or on an external solid input panel that is a part of the user interface unit of the electronic reading device 1, and the user interface unit of the electronic reading device 1 takes the pattern drawn by the user as input information. The input through the user interface unit in the keyboard input mode means that the user inputs character information by touching a virtual keyboard (for example, reference numeral 19 of fig. 9) on the screen of the electronic reading device 1 or by pressing/clicking an external physical keyboard which is a part of the user interface unit of the electronic reading device 1.
In addition, the touch described herein may be a contact-type touch over a non-contact-type touch, for example, when an infrared screen is used, the screen may not be touched. The touch is not limited to a hand touch, and various pen touches are possible. The screen used by the display 13 of the present invention may be a resistive screen, an infrared screen, a resistive screen, or the like.
In step S114, the content input by the user on the second display area 22 is received through the user interface unit, and the input content is taken as draft information.
In step S115, the processor 10 displays the draft information in the second display area 22 of the display 13.
As illustrated in fig. 2, the user drafts on the second display area 22. Specifically, the user inputs a complex mathematical formula as draft information by a manual writing manner. The processor 10 displays the draft information in the second display area 22 of the display 13.
Through the processing, the user can read and draft while reading very conveniently. Especially for students in the learning stage, the practicability of the electronic reading equipment is greatly improved.
Preferably, steps S116 to S119 may be further performed.
In step S116, when receiving the draft information input by the user, the processor 10 determines whether the distance between the display position of the draft information input by the user in the second display area 22 and the set edge of the second display area 22 is smaller than a first preset value. If yes, the process proceeds to step S117 or directly to step S118, otherwise, the process proceeds to step S120.
In step S117, it is determined whether the area of the first display area 21 is smaller than a second preset value, and if the area is not smaller than the second preset value, the process proceeds to step S118. In the case that the height of the first display region 21 is constant, whether the area of the first display region 21 is smaller than the second preset value can be determined by whether the width is smaller than a certain preset value. In the case that the width of the first display region 21 is constant, whether the area of the first display region 21 is smaller than the second preset value can be determined by whether the height is smaller than a certain preset value.
Step S118, further reducing the first display area 21 for presenting the digital work to a new first display area, and increasing the second display area 22 to a new second display area.
In fig. 2, pen 20 is touching input in a manual writing manner. The processor 10 obtains the distance d1 between the pen position of the user and the bottom edge (set edge) of the second display area 22, and determines whether d1 is smaller than a first preset value. Through steps S116 and S118, when the input position of the user is closer to the bottom edge, the determination result will be yes, so that the processor increases the second display area 22 to a new second display area 22 as shown in fig. 4 shown in fig. 2. Therefore, the user can input the draft information more conveniently, and the user friendliness is improved.
Similarly, when the first display area 21 and the second display area 22 are distributed left and right, the right boundary of the second display area may be used as the setting edge.
Through S117, the first display area for displaying the digital work may not be too small, thereby further improving user friendliness.
Preferably, the user is allowed to move the boundary of the first display area 21 and the second display area 22 by dragging the boundary line between the first display area 21 and the second display area 22. Thereby further facilitating user adjustment of the size of the two display areas.
In step S119, a scroll bar (reference numeral 17 in fig. 5) substantially perpendicular to the setting edge is provided in the second display area 22 while keeping the sizes of the first display area 21 and the second display area 22 unchanged.
In this way, when the user pulls the scroll bar, the draft information displayed in the second display area 22 is scrolled, so that the user can input more draft information in the blank area due to the scroll operation. As shown in fig. 5, the second display area 22 does not display the draft information of the uppermost portion due to the upward scroll.
Example two
A further embodiment of the invention is described below in conjunction with fig. 6, 7 and 12. The electronic reading device of this embodiment is very convenient for student users to answer when doing exercises.
In this embodiment, the processor 10 may copy or cut the content of the user selection area 23 in the second display area 22 as image information to the first user-specified position 24 of the first display area 21 according to the user's adoption instruction, and display the image information of the user selection area 23 at the first user-specified position 24.
The user may first click the virtual selection button 18 and the electronic reading device 1 receives an adoption instruction from the user (fig. 12, S120). Then, the touch is continued along the diagonal line of the desired selection area in the screen (fig. 12, S121), and thus the processor 10 determines a user selection area 23 diagonal to the user sliding trajectory (fig. 12, S122). Of course, the user selection area 23 may also be determined in a variety of ways, such as by pulling a mouse.
After determining a user selection area 23 selected by the user in the second display area 22, the processor 10 further detects a continuous touch operation (also referred to as a drag operation) of the user from the user selection area 23 to the first display area 21 (fig. 12, S123). The processor 110 sets the drag operation as the aforementioned adoption instruction, and sets the end position of the drag operation as the first user-specified position (fig. 12, S124). Then, the content of the user selection area 23 in the second display area 22 is copied or cut as image information to the first user designated position 24 of the first display area 21, and the image information of the user selection area 23 is displayed at the first user designated position 24 (fig. 12, S125). In the specific dropping of the copied or cut image information, the image information at the drag operation start point position may be copied or cut at or near the drag operation end point position.
Then, the processor 10 may save the copied or cut image information and its positional relationship with the content of the currently presented digital work to the memory 11 as a part of the currently presented digital work, or save the copied or cut image information and its positional relationship with the content of the currently presented digital work to the memory 11 as an attachment associated with the currently presented digital work. As to how to save the copied or cut image information, the way in which annotations are saved in chinese patent applications CN201280019699.5 and cn200880017259.x can be referred to for saving. Both of these patent applications are incorporated herein by reference in their entirety.
Further, after the user interface unit receives a second user instruction that draft is not required, the second display area 22 is canceled, and the first display area 21 is restored to the original screen display area. As described above, after the user clicks the "draft" button 15, the second display area 22 is displayed. As an alternative example, the draft button 15 may be changed to the "close draft" button 15 for canceling the draft mode after the user clicks the "draft" button 15, so that the processor 10 restores the first display area 21 to the original screen display area when the user clicks the button 15 again.
Furthermore, after the user interface unit receives a second user instruction that draft is not required, the draft information currently displayed in the second display area 22 may be saved in the memory 11, the second display area 22 may be cancelled, and the first display area may be restored 21 to the original screen display area. In this way, the draft information stored in the memory 11 can be displayed 22 in the second display area after the user interface unit receives the first user instruction about the draft to be drafted.
EXAMPLE III
A further preferred embodiment is described below in connection with fig. 9 and 13. This embodiment is very convenient for students to write silently.
The user may send a third user instruction (fig. 13, S130) about to initiate the dictation mode by clicking the "dictation" button 16 (see fig. 4-6, 8). The user interface unit receives a third user instruction about to start the dictation mode (fig. 13, S131). After the user interface unit receives a third user instruction about to start the dictation mode, the processor 10 hides the digital work currently displayed in the first display area 21 so that the user can input/erase any content in the second display area 22 through the user interface unit in a manual writing manner or in a keyboard input manner, and displays the input content as dictation information in the second display area (fig. 13, S132). The digital work currently displayed by the first display area 21 may be hidden by closing the first display area 21, or the current digital work may not be displayed in the first display area without closing the first display area, or may be displayed in a blurred manner so as to be obscured from the view of the user.
After the user memorization is completed, a fourth user instruction for starting the memorization comparison mode can be transmitted by clicking the button 16 (see fig. 9, the button 16 originally used for transmitting the third user instruction for starting the memorization comparison mode has now automatically changed to the button 16 for transmitting the fourth user instruction for starting the memorization comparison mode) (fig. 13, S133). The user interface unit receives a fourth user instruction about the start of the dictation collation mode (fig. 13, S134). After the user interface unit receives the fourth user instruction for starting the dictation contrast mode, the processor 10 resumes displaying the digital work currently displayed in the first display area and simultaneously displays the dictation information input by the user in the second display area (fig. 13, S135). After a fourth user instruction for starting the dictation contrast mode is issued, the button 16 is automatically changed to a fifth instruction for sending a fourth instruction for closing the dictation mode (refer to reference numeral 16 of fig. 10). The user interface unit receives a fifth instruction to turn off the dictation mode (fig. 13, S137). The user clicks on button 16 to send a fourth user instruction to turn off the dictation mode. After the user interface unit receives a fifth instruction (fig. 13, S137) to turn off the dictation mode, the processor 10 saves the dictation information currently displayed in the second display area 22 and turns off the second display area 22 (fig. 13, S138).
Those skilled in the art will appreciate that the various elements or steps of the invention described above may be implemented using a general purpose computing device, that is, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and that they may alternatively be implemented using program code executable by a computing device, such that the program code is stored in a memory device and executed by a computing device, and separately fabricated into various integrated circuit modules, or fabricated into a single integrated circuit module from multiple modules or steps.
