[0055] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0056] Reference Figure 1 , a flow chart of a method for controlling the edge area of ​​an electronic whiteboard screen according to an embodiment of the present application is shown. The method for controlling the edge area of ​​an electronic whiteboard screen may include at least steps S100-S400:

[0057] S100: Acquire historical touch data of the electronic whiteboard screen.

[0058] S200: Analyze historical touch data to determine layout information and area type.

[0059] The area type characterizes the corresponding supported touch modes, for example, whether the volume and brightness are touch-controlled in different independent areas, or touch-controlled based on different gestures in a shared area.

[0060] S300: Generate an initial edge area on the electronic whiteboard screen according to the layout information and the area type.

[0061] S400: In response to a touch on an initial edge area, adjust the volume or the brightness.

[0062] The edge area touch control method of the electronic whiteboard screen in the embodiment of the present application can be executed by the processor of the electronic whiteboard.

[0063] The technical solution of the embodiment of the present application obtains historical touch data of the electronic whiteboard screen, analyzes the historical touch data, determines layout information and determines area types, the area type represents the corresponding supported touch mode, generates an initial edge area on the electronic whiteboard screen according to the layout information and the area type, and performs volume adjustment or brightness adjustment in response to the touch of the initial edge area. Based on the analysis of historical touch data, an initial edge area located at the edge of the electronic whiteboard screen is generated for the user to adjust the volume or brightness by touching the initial edge area, which is convenient and quick and helps to improve user experience.

[0064] In one embodiment, when a user touches the screen of an electronic whiteboard, the corresponding touch data can be collected through the touch sensor under the screen of the electronic whiteboard, so after a certain time and number of operations, the corresponding historical touch data can be collected. The historical touch data may include the location, number, time, moving direction, moving distance and speed of the touch point, etc., for subsequent statistical analysis.

[0065] In one implementation, the historical touch data is analyzed in step S200 to determine the arrangement information, including steps S210-S230:

[0066] S210: Analyze historical touch data to determine a number of sub-areas where sliding operations are performed on the electronic whiteboard screen and a touch frequency of each sub-area.

[0067] Optionally, the historical touch data is analyzed to determine a number of sub-areas where sliding operations are performed on the electronic whiteboard screen and the touch frequency of each sub-area. The size of the sub-area can be adjusted based on needs, for example, the screen is divided into grid sub-areas, and then the touch frequency of each sub-area is counted.

[0068] S220 , determining a target sub-region with the highest touch frequency, and determining layout information according to a position and a size of the target sub-region.

[0069] In the embodiment of the present application, the layout information includes the deployment position and deployment size of the initial edge area.

[0070] Among them, S220 includes:

[0071] S2201. Determine, according to the frequency threshold, candidate sub-regions other than the target sub-region whose touch frequency is greater than or equal to the frequency threshold.

[0072] Optionally, a target sub-region with the largest touch frequency and candidate sub-regions other than the target sub-region with a touch frequency greater than or equal to a frequency threshold are determined, and the frequency threshold is set based on needs.

[0073] S2202: When the target sub-region has an adjacent candidate sub-region, the sum of the size of the target sub-region and the size of the adjacent candidate sub-region is determined as the deployment size; when the target sub-region does not have an adjacent candidate sub-region, the size of the target sub-region is determined as the deployment size.

[0074] Optionally, assume that the screen is divided into grids, where grid A is the target sub-region, and with grid A as the center, the grids above, below, left, right, upper left, upper right, lower left, and lower right of grid A form a nine-square grid with grid A. If 8 grids other than grid A have candidate sub-regions, it is considered that grid A has adjacent candidate sub-regions, that is, the target sub-region has adjacent candidate sub-regions.

[0075] Then, when the target sub-region has an adjacent candidate sub-region, the sum of the size of the target sub-region and the size of the adjacent candidate sub-region is determined as the deployment size. When the target sub-region does not have an adjacent candidate sub-region, the size of the target sub-region is directly determined as the deployment size.

[0076] S2203: When the target sub-region is not an edge region, if the adjacent candidate sub-region is an edge region, the position of the adjacent candidate sub-region is used as the deployment position; if the adjacent candidate sub-region is a non-edge region, the position of the sub-region closest to the target sub-region is used as the deployment position.

[0077] Optionally, assuming that the screen is divided into grids, the outermost circle of grids is considered to be edge grids, that is, edge areas. In an embodiment of the present application, when the target sub-area is a non-edge area, if the adjacent candidate sub-area is an edge area, the position of the adjacent candidate sub-area is used as the deployment position; and if the adjacent candidate sub-area is a non-edge area, the position of the sub-area closest to the target sub-area is used as the deployment position. It should be noted that when the initial edge area is subsequently generated, the center of the deployment position is used as the center of the initial edge area, and then the initial edge area is generated. In an embodiment of the present application, analysis is performed based on the user's usage habits, and the deployment position is determined based on the user's frequently used areas to better adapt to the user's operating habits.

[0078] In one embodiment, the historical touch data is analyzed in step S200 to determine the area type, including steps S230-S250:

[0079] S230: Determine a touch operation and touch time corresponding to each sub-area, where the touch operation includes volume adjustment and brightness adjustment.

[0080] Optionally, after determining each sub-area, a touch operation and a touch time corresponding to each sub-area are further determined, and the touch operation includes volume adjustment and brightness adjustment.

[0081] S240: Determine a first frequency for adjusting the volume and a second frequency for adjusting the brightness, and determine a probability of an erroneous operation according to the touch operation and the touch time.

[0082] Optionally, a first frequency for volume adjustment and a second frequency for brightness adjustment are determined, and then analysis is performed based on each touch operation and the corresponding touch time. For example, the interval threshold is set to 5 seconds. If there are operations in opposite directions within two seconds, for example, the volume is increased and the volume is decreased at the same time within 5 seconds, or the brightness is increased and the brightness is decreased at the same time within 5 seconds, then the two touches are considered as erroneous operations, and the probability of erroneous operations is determined based on the ratio of the number of erroneous operations to the total number of touch operations.

[0083] S250: When the probability of misoperation is greater than or equal to the probability threshold, the area type is determined to be an independent area; when the probability of misoperation is less than the probability threshold, the area type is determined to be a shared area.

[0084] Optionally, when the probability of misoperation is greater than or equal to the probability threshold, such as the risk of misoperation of the screen is high or the screen has low accuracy in gesture recognition, the area type is determined to be an independent area, that is, the volume adjustment and brightness adjustment are set separately and used separately. When the probability of misoperation is less than the probability threshold, such as the risk of misoperation of the screen is low or the screen has high accuracy in gesture recognition, the area type is determined to be a shared area, that is, the volume adjustment and brightness adjustment functions are set in the same area, and whether to adjust the volume or the brightness is determined based on different gestures, which is conducive to reducing the memory burden and improving simplicity.

[0085] In one implementation, step S300 includes step S310 or S320:

[0086] S310: When the area type is a shared area, a shared area having a size equal to the deployment size is generated at the deployment position on the electronic whiteboard screen as an initial edge area.

[0087] Optionally, when the area type is a shared area, at the deployment position on the electronic whiteboard screen, a shared area having a size equal to the deployment size is generated as an initial edge area with the center point of the deployment position as the center.

[0088] S320: When the area type is an independent area, two first independent areas and a second independent area, each of which is half the size of the deployment size, are generated as initial edge areas at the deployment position in the electronic whiteboard screen.

[0089] Optionally, when the area type is an independent area, at the deployment position in the electronic whiteboard screen, with the center point of the deployment position as the center, two first independent areas and a second independent area, each of which is half the size of the deployment size, are generated as initial edge areas. The first independent area and the second independent area are symmetrically arranged, which helps to better avoid misoperation.

[0090] In one implementation, step S400 includes step S410 or S420:

[0091] S410: When the initial edge area is generated based on the shared area, in response to performing gesture analysis on a touch of the initial edge area, adjusting the volume or the brightness according to the gesture analysis result.

[0092] Optionally, users can set different gestures as needed, such as single-finger sliding gestures, two-finger up and down sliding gestures, and three-finger up and down sliding gestures. Users can touch in the initial edge area, and the processor will perform gesture analysis on the touch model. For example, a single-finger sliding gesture: normally identifies the writing trajectory according to the movement trajectory and speed of the touch point, generates the corresponding writing input, and displays the writing content on the large screen. Even if the initial edge area is deployed, it does not affect the normal writing of the screen itself; a two-finger up and down sliding gesture: adjusts the brightness; a three-finger up and down sliding gesture: adjusts the volume. In addition, touching with different gestures in the initial edge area can avoid conflicts with gestures in other areas of the screen, can be well distinguished, and can avoid confusion with content operations, thereby optimizing the user experience.

[0093] S420: When the initial edge area is generated based on the independent area, the volume is adjusted in response to the touch on the first independent area, or the brightness is adjusted in response to the touch on the second independent area.

[0094] Optionally, when the initial edge area is generated based on the independent area, the touch of the first independent area, such as the touch of one finger, two fingers or three fingers, is used to adjust the volume; similarly, the touch of the first independent area, such as the touch of one finger, two fingers or three fingers, is used to adjust the brightness.

[0095] Optionally, when adjusting the brightness, the sliding distance and speed of the touch are analyzed. It is assumed that the formula for the brightness adjustment of the screen is Δbrightness=0.1*sliding distance (cm)*speed (cm / s). For example, the upward sliding distance is 10 cm and the sliding speed is 2 cm / s. The calculated brightness adjustment amount is Δbrightness=0.1*10*2=2. If the current brightness is 50%, the brightness after sliding is 52%. On the contrary, if the downward sliding distance is 10 cm, the brightness after sliding is 48%. The design of the formula is based on the strength and sliding amplitude of the user's gesture. A larger sliding distance and a faster speed will lead to changes, which is more in line with reality. The formula for volume adjustment is similar. Assuming the current volume is 50%, the upward sliding distance is 10 cm, and the sliding speed is 2 cm / s, Δvolume=0.1*10*2=2, corresponding to a volume of 52% after sliding.

[0096] In one implementation, the edge area touch control method of the electronic whiteboard screen of the embodiment of the present application may further include steps S510-S530:

[0097] S510: Continuously collect real-time touch data of the initial edge area within a preset time length.

[0098] S520: Analyze the real-time touch frequency of the initial edge area according to the real-time touch data.

[0099] Optionally, based on the newly determined real-time touch data, the real-time touch frequency of the initial edge area is re-analyzed.

[0100] S530: when the initial edge area is generated based on the shared area and the real-time touch frequency is greater than the frequency threshold, expand the size of the initial edge area;

[0101] When the initial edge area is generated based on the independent area and the real-time touch frequency corresponding to the first independent area is greater than the real-time touch frequency corresponding to the second independent area, the size of the first independent area is expanded; or, when the initial edge area is generated based on the independent area and the real-time touch frequency corresponding to the first independent area is less than the real-time touch frequency corresponding to the second independent area, the size of the second independent area is expanded.

[0102] Optionally, when the initial edge area is generated based on the shared area and the real-time touch frequency is greater than the frequency threshold, the size of the initial edge area is expanded, indicating that the user's operation frequency has increased. At this time, the size of the initial edge area is adaptively expanded; similarly, if the real-time touch frequency is less than or equal to the frequency threshold, the size of the initial edge area may remain unchanged or be reduced.

[0103] Optionally, when the initial edge area is generated based on the independent area, and the real-time touch frequency corresponding to the first independent area is greater than the real-time touch frequency corresponding to the second independent area, the size of the first independent area is expanded, and in some embodiments, the size of the second independent area can be reduced at the same time, so as to keep the size of the overall initial edge area unchanged; when the initial edge area is generated based on the independent area, and the real-time touch frequency corresponding to the first independent area is less than the real-time touch frequency corresponding to the second independent area, the size of the second independent area is expanded, and in some embodiments, the size of the first independent area can be reduced at the same time, so as to keep the size of the overall initial edge area unchanged. In the embodiment of the present application, through this adaptive adjustment, the user's intention can be more accurately identified, the probability of misoperation can be reduced, and the overall user experience can be improved.
