Detailed ways

In the following description, for purposes of illustration and not limitation, specific details such as specific system structures, interfaces, techniques, etc. are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

The following description will be given in conjunction with the accompanying drawings and specific embodiments.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of an embodiment of an electronic whiteboard control method of the present application. The electronic whiteboard control method of this embodiment includes but is not limited to the following steps.

Step S100, the electronic whiteboard control device acquires the command icon set by the electronic whiteboard.

The connection form between the electronic whiteboard and the electronic whiteboard control device may be a wired connection or a wireless connection, and the specific connection form is not limited here. The electronic whiteboard control device may be a terminal device such as a computer and a mobile phone.

The specific implementation of step 100 can be as follows: the electronic whiteboard recognizes the coordinates of each point on the command icon drawn by the user, and transmits the coordinates of each point to the electronic whiteboard control device, and the electronic whiteboard control device receives the coordinates of each point and passes the coordinates of each point. The coordinates of get the command icon set by the electronic whiteboard.

Preferably, before step S100, it further includes a step: the electronic whiteboard control device determines a calibration command area set by the electronic whiteboard. Wherein, the set calibration command area may be an existing area on the electronic whiteboard, and the electronic whiteboard control device defaults this area as the calibration command area. It is also possible to draw a graph for the user at any position on the electronic whiteboard, the electronic whiteboard detects the set of coordinates of each point on the graph, and transmits the set of coordinates of each point to the electronic whiteboard control device, and the electronic whiteboard control device According to the set of coordinates of the respective points and their positions, an area is correspondingly determined on the display screen as the calibration command area. The calibration command area may be a rectangle, a circle, a square, and an irregular geometric shape, etc., which are not limited here.

Preferably, the electronic whiteboard control device identifies a user's operating point on the electronic whiteboard, and defines a rectangular area with a diagonal corner closest to the operating point and the electronic whiteboard as the calibration command area.

Please refer to FIG. 2 for details. FIG. 2 is a schematic diagram showing the setting of the calibration command area. It should be noted that, in this technical solution, the program loaded inside the electronic whiteboard control device controls the completion of the corresponding steps, and the following description uses the electronic whiteboard control The device acts as the subject of control. As can be seen in this figure, the electronic whiteboard control device recognizes an operation point 410 drawn by the user near the upper left corner of the electronic whiteboard 400, and the electronic whiteboard control device defines the operation point 410 and the upper left corner of the electronic whiteboard as the opposite corner. The rectangular area of the line serves as the calibration command area 401 . Of course, in other embodiments, the user can also draw operation points on other positions of the electronic whiteboard 400 according to the operating habits, for example, near the lower left corner, the upper right corner and the lower right corner of the electronic whiteboard 400, etc. It should be noted here that , in order to ensure the realization of other functions of the electronic whiteboard 400 and the aesthetics of the overall display, the area of the calibration command area 401 should not be too large. The process of setting the command area 401 on the electronic whiteboard 400 and setting icons in the calibration command area 401 will be displayed on the display screen of the control device synchronously to prompt the user whether the setting process meets the requirements.

After the calibration command area 401 is defined, the electronic whiteboard control device will display a plurality of default icons 402 in the area corresponding to the calibration command area 401 on the screen of the electronic whiteboard control device. The number of default icons can be determined in the electronic whiteboard control device. set up. In addition, the shape 402 of the default icon is randomly generated by the electronic whiteboard control device, and may be a circle, a square, a star, or the like.

In this way of setting the calibration command area and setting the icon in the calibration command area, the user can choose to draw an icon with the same shape as the default icon at the default icon position, when the user does not want to draw an icon with the same shape as the default icon , you can also draw icons of other shapes as setting icons. The user can choose and draw the icon shape at will. The electronic whiteboard recognizes the coordinates of each point of the graph drawn by the user, and transmits the coordinates of each point to the electronic whiteboard control device. The electronic whiteboard control device will close the drawn icon according to the coordinates of each point. Process to ensure that the drawn icon shape is a closed shape, so as to facilitate subsequent determination of the icon operated by the user.

The electronic whiteboard control device recognizes the default icon to be replaced by the icon drawn by the user according to the position where the user draws the icon. For example, if the user draws an icon at the star-shaped position in FIG. 2, the electronic whiteboard control device replaces the star with the icon drawn by the user. shape default icon.

The user can also draw icons in sequence. When drawing an icon, start by pressing down the brush (or finger, etc.) and end by raising the brush. The electronic whiteboard control device will record the coordinates of each point in the process of drawing the icon by the user as the icon's Metadata describing the shape of this icon. Each time an icon is drawn, the electronic whiteboard control device displays the icon drawn by the user and replaces the default icon; when the number of icons drawn by the user reaches the predefined number, the setting process is automatically completed, and the electronic whiteboard control device prompts User: The electronic whiteboard control device has recorded all the setting icon information for subsequent identification.

Step S110, associate the command icon with the operation instruction.

The electronic whiteboard control device associates the command icon with the operation instruction corresponding to the first default icon at the position where it recognizes that the command icon is located at the first default icon among the plurality of default icons, and recognizes that the command icon is located at the position of the second default icon , associate the command icon with the operation instruction corresponding to the second default icon, and so on, associate the command icon drawn by the user with the operation instruction at the position of the default icon.

Pre-associated operation instructions can include creating a new whiteboard, freezing the whiteboard interface, and deleting annotations. Among them, creating a whiteboard means that the electronic whiteboard control device creates a new whiteboard interface on its display; freezing the whiteboard interface: after the user operates this function, subsequent operations on the electronic whiteboard will not be recognized. After creating a new whiteboard interface, delete the content on the electronic whiteboard; delete annotation: after the user operates this function, click the annotation to be deleted on the electronic whiteboard, and the electronic whiteboard control device will automatically delete the annotation. This process generally requires the user to combine the function of freezing the whiteboard interface, so as to manually delete the mark on the electronic whiteboard and ensure that the display contents of the electronic whiteboard and the display of the control device are consistent.

Step S120, identifying the operation coordinates in the electronic whiteboard.

Preferably, before step S120, it can also include steps: judging whether the electronic whiteboard has set a command icon; if so, go to step S120 to identify the operation coordinates in the electronic whiteboard; otherwise, return to setting the calibration command area and set the calibration command area in the calibration command area Steps to set the command icon inside.

In the process of using the electronic whiteboard, if the user needs the function corresponding to the icon, click (including single-click, double-click, etc.) the icon area of the electronic whiteboard, and the electronic whiteboard will feedback a coordinate position to the electronic whiteboard control device. The device recognizes the icon to which it belongs based on this coordinate position.

Since the setting icon is drawn by the user, it is likely to be an irregular polygon. We can use the ray method to determine whether the operation point (ie the user's operation position) is within the icon. The principle of the ray method is briefly introduced below. .

The ray method is a basic method for judging the relationship between points and polygons, which generally includes the following situations. 1. If the point (operation point) belongs to one of the vertices of the polygon, it is considered to be in the icon; 2. If the point is on any side of the polygon, it is considered to be in the icon; 3. The line is drawn from the point to be judged to a certain direction, Calculate the number of intersection points with the polygon. If the number is even or 0, the point is outside the polygon, and if it is odd, it is inside the polygon; 4. When the ray passes through the vertex of the polygon, some special judgment processing is required: a) The ray If the points passing through belong to one side of the ray, it is considered to be disjoint; b) If the two endpoints of the line segment are on both sides of the ray, it is considered to intersect the ray. The basic principle of the ray method for the relationship between points and polygons belongs to the well-known technology of those skilled in the art, so it will not be repeated here.

When it is determined that the user's operation position is not located inside any icon in the calibration command area, the operation action is not responded. If it is judged that the user's operation position is inside an icon in the calibration command area, the next step is entered.

Step S130: Execute the operation instruction corresponding to the command icon at the position where the operation coordinates are located.

The electronic whiteboard control device receives the operation coordinates executed on the electronic whiteboard from the electronic whiteboard, and executes the operation instruction corresponding to the command icon when it is determined that the operation coordinates are located in the command icon area.

The control method flow ends.

In the electronic whiteboard control method in this embodiment, by customizing the calibration command area, drawing setting icons by yourself, and defining the associated functions of the setting icons, the user can complete the electronic whiteboard that should be done on a computer (or other control devices, such as a mobile phone) (including creating a whiteboard, freezing the whiteboard interface, and deleting annotations, etc.), so users do not need to switch between the computer and the electronic whiteboard frequently when using the electronic whiteboard. Setting a personalized drawing icon as a setting icon greatly optimizes the user's operating experience of using the electronic whiteboard.

Please refer to FIG. 3. FIG. 3 is a block diagram of a module of an embodiment of the electronic whiteboard control device of the present application. The electronic whiteboard control device of this embodiment includes but is not limited to an acquisition module 301, an association module 302, an identification module 303, an execution module 304, A determination module 305 , a display module 306 and a determination module 307 are provided.

Wherein, the connection form between the electronic whiteboard and the electronic whiteboard control device may be a wired connection or a wireless connection, and the specific connection form is not limited here. The electronic whiteboard control device may be a terminal device such as a computer and a mobile phone.

Specifically, the determining module 305 is used to determine the calibration command area set by the electronic whiteboard. Among them, in the set calibration command area, a graph can be drawn for the user at any position on the electronic whiteboard, the electronic whiteboard detects the set of coordinates of each point of the graph, and transmits the set of coordinates of each point to the In the electronic whiteboard control device, the determining module 305 of the electronic whiteboard control device correspondingly determines an area on the display screen as the calibration command area according to the set of coordinates of the respective points and their positions. The calibration command area may be a rectangle, a circle, a square, and an irregular geometric shape, etc., which are not limited here.

Preferably, the determining module 305 identifies an operation point of the user on the electronic whiteboard, and defines a rectangular area with a diagonal corner closest to the operation point and the electronic whiteboard as the calibration command area. For the specific steps of determining the calibration command area, please refer to the relevant description in the embodiment of the electronic whiteboard control method in the above embodiment.

The display module 306 is configured to display a plurality of default icons in an area corresponding to the calibration command area on the screen of the electronic whiteboard control device, and the default icons may have shapes such as circles, squares, and stars.

The obtaining module 301 is used to obtain the command icon set by the electronic whiteboard. The association module 302 is used to associate the command icon with the operation instruction.

The user can choose to use the default icon as the set icon, and when the user does not want to use the default icon as the set icon, he can also draw an icon by himself as the set icon. The user can choose to draw the icon shape at will, and the electronic whiteboard sets the coordinates of each point of the graph drawn by the user, and transmits the coordinates of each point to the association module 302 of the electronic whiteboard control device, and the association module 302 will draw according to the coordinates of each point. The icon is closed to ensure that the drawn icon shape is a closed shape, so as to facilitate the subsequent determination of the icon operated by the user.

The association module 302 identifies the default icon to be replaced by the user-drawn icon according to the position where the user draws the icon. For example, if the user draws an icon at the star-shaped position in FIG. 2 , the association module 302 replaces the star-shaped default icon with the icon drawn by the user.

The user can also draw icons in sequence. When drawing an icon, it starts with the brush (or finger, etc.) clicked down, and ends when the brush is lifted. Data describing the shape of this icon. Each time an icon is drawn, the display module 306 displays the icon drawn by the user, and the association module 302 replaces the default icon with the icon drawn by the user; after the number of icons drawn by the user reaches a predefined number, the setting process is automatically completed. Prompt the user: the association module 302 has recorded all set icon information for subsequent identification.

Pre-associated operation instructions can include creating a new whiteboard, freezing the whiteboard interface, and deleting annotations. Among them, creating a whiteboard means that the electronic whiteboard control device creates a new whiteboard interface on its display; freezing the whiteboard interface: after the user operates this function, subsequent operations on the electronic whiteboard will not be recognized. After creating a new whiteboard interface, delete the content on the electronic whiteboard; delete annotation: after the user operates this function, click the annotation to be deleted on the electronic whiteboard, and the electronic whiteboard control device will automatically delete the annotation. This process generally requires the user to combine the function of freezing the whiteboard interface, so as to manually delete the mark on the electronic whiteboard and ensure that the display contents of the electronic whiteboard and the display of the control device are consistent.

The judgment module 307 is used to judge whether the electronic whiteboard has set a command icon; if so, the identification module 303 identifies the operation coordinates in the electronic whiteboard; otherwise, the determination module 305 needs to re-determine the calibration command area.

In the process of using the electronic whiteboard, if the user needs the function corresponding to the icon, then click (including single-click, double-click, etc.) the icon area of the electronic whiteboard, and the electronic whiteboard will feed back a coordinate position to the recognition module 303 at this time, and the recognition module 303 according to This coordinate position identifies the icon to which it belongs.

The execution module 304 is configured to execute the operation instruction corresponding to the command icon at the position of the operation coordinate. Since the setting icon is drawn by the user, it is likely to be an irregular polygon. The execution module 304 uses the ray method to determine whether the operation point (ie, the user's operation position) is within the icon. The principle of the ray method is briefly described below. introduce.

The ray method is a basic method for judging the relationship between points and polygons, which generally includes the following situations. 1. If the point (operation point) belongs to one of the vertices of the polygon, it is considered to be in the icon; 2. If the point is on any side of the polygon, it is considered to be in the icon; 3. The line is drawn from the point to be judged to a certain direction, Calculate the number of intersection points with the polygon. If the number is even or 0, the point is outside the polygon, and if it is odd, it is inside the polygon; 4. When the ray passes through the vertex of the polygon, some special judgment processing is required: a) The ray If the points passing through belong to one side of the ray, it is considered to be disjoint; b) If the two endpoints of the line segment are on both sides of the ray, it is considered to intersect the ray. The basic principle of the ray method for the relationship between points and polygons belongs to the well-known technology of those skilled in the art, so it will not be repeated here.

When the execution module 304 determines that the user's operation position is not located inside any icon in the calibration command area, it does not respond to the operation action. If the execution module 304 determines that the user's operation position is located inside an icon in the calibration command area, the operation instruction corresponding to the command icon at the position where the operation coordinates are located is executed.

In the electronic whiteboard control device in this embodiment, by customizing the command area and icons, the user can complete the functions that should be performed on the computer (or other control devices, such as mobile phones, etc.) on the electronic whiteboard (including creating a whiteboard, freezing the whiteboard, etc.). interface and delete labels, etc.), so that the user does not need to frequently switch between the computer and the electronic whiteboard when using the electronic whiteboard, which greatly facilitates the user's operating experience of using the electronic whiteboard.
