In some embodiments, the display device 200 may have a touch interaction function, and a user may operate the host machine by only lightly touching the display with a finger, so as to get rid of operations of a keyboard, a mouse, and a remote controller, and make human-computer interaction more straightforward. Based on the display device 200, the display device 200 can support a touch interaction function by adding a touch component. In general, the touch-sensing component may constitute a touch screen together with the display 260. A user can input different control instructions on the touch screen through touch operation. For example, the user may input a click, slide, long press, double click, etc. touch command, and different touch commands may represent different control functions.
In order to implement the different touch actions, the touch assembly may generate different electrical signals when a user inputs different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.
For example, when a user inputs a click touch action at any program icon position in the application program interface, the touch component senses the touch action and generates an electrical signal. After receiving the electrical signal, the controller 250 may first determine a duration of a level corresponding to a touch action in the electrical signal, and when the duration is less than a preset time threshold, recognize that a click touch instruction is input by the user. The controller 250 then extracts the positional features generated by the electrical signals to determine the touch position. And when the touch position is within the display range of the application icon, determining that the user inputs a click touch instruction at the position of the application icon. Accordingly, the click touch command is used to execute a function of running a corresponding application program in the current scene, so that the controller 250 may start running the corresponding application program.
For another example, when the user inputs a sliding motion in the media asset presentation page, the touch component also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When the determined duration is longer than the preset time threshold, the position change condition generated by the signal is judged, and obviously, for the interactive touch action, the generation position of the signal changes, so that the sliding touch instruction input by the user is determined. The controller 250 determines the sliding direction of the sliding touch instruction according to the change condition of the position of the signal generation, and controls to turn pages of the display frame in the media asset display page so as to display more media asset options. Further, the controller 250 may extract features such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a page-turning screen control according to the extracted features, so as to achieve a hand-following effect.
Similarly, for the touch instruction such as double click, long press, etc., the controller 250 may execute the corresponding control function according to the preset interaction rule by extracting different features and determining the type of the touch instruction through feature judgment.

In the state of picking up the brush control 823, the user can input content based on contact with the second drawing region 822, that is, a sliding path of the user on the second drawing region 822.
Further, after the user selects parameters such as a line color, a line type, a line thickness, and the like in the brush toolbar 920, in order not to affect an area where drawing can be performed, the brush toolbar 920 may be hidden by contacting the brush control 823 with the second drawing area 822, and an interface of the electronic drawing board behind the brush toolbar 920 is hidden as shown in fig. 6.
In some embodiments, after the user leaves a sliding path through contact with the second drawing area 822, the controller controls to store the coordinates of the pixel points that the sliding path passes through into the second operation list, and refreshes the first drawing layer based on the second operation list, so as to fill the pixel points corresponding to the coordinates of the pixel points stored in the memory in the second preset area (the second drawing area 822) of the first drawing layer with color, so as to display the sliding path in the second preset area (the second drawing area 822), thereby completing drawing of the sliding path.
In some embodiments, the user may begin drawing after configuring the parameters of the brush control. Because the second layer to which the first control area 811 and the second control area 821 belong is arranged in a floating manner on the upper layer of the first layer to which the first drawing area 812 and the second drawing area 822 belong, when a user picks up the brush control and starts drawing, the second layer will receive a sliding operation from a drawing starting point to a drawing end point input by the user prior to the first layer, when the second layer receives a sliding track corresponding to the sliding operation from the drawing starting point to the drawing end point input by the user, the controller controls to store pixel point coordinates passed by the sliding path into the first operation list, and determines a target area according to the pixel point coordinates corresponding to the drawing starting point, the target area is the drawing area to which the drawing starting point is located, if the drawing starting point belongs to the first drawing area 812, the first layer is refreshed according to the brush parameters indicated by the first brush control and the first operation list stored in the memory, and carrying out color filling or replacement on pixel points which pass through the sliding path in the first drawing area. And if the drawing starting point belongs to the second drawing area 822, refreshing the first layer according to the drawing parameters indicated by the second drawing control and a second operation list stored in the memory, and performing color filling or replacement on the pixel points passing through the sliding path in the second drawing area 822.
For example, after the user respectively configures the brush parameters of the brush control 813 and the brush control 823, if the drawing start point is in the first drawing area 812, the controller will read the brush parameters of the brush control 813, at this time, the brush control 813 is in a pick-up state, if the user continues to perform touch movement on the electronic drawing board by using the brush control 813, all the pixels located on the first drawing area 812 on the touch movement trajectory will be filled according to the brush parameters of the brush control 813, and all the pixels located on the second drawing area 822 on the touch movement trajectory will not be filled. Or, if the drawing start point is in the second drawing area 822, the controller reads the brush parameter of the brush control 823, at this time, the brush control 823 is in a pick-up state, if the user continues to perform touch movement on the electronic drawing board using the brush control 823, all pixel points located on the second drawing area 822 on the touch movement trajectory will be filled according to the brush parameter of the brush control 823, and all pixel points located on the first drawing area 812 on the touch movement trajectory will not be filled.
In some embodiments, the user can erase the contents in the first drawing area 812 and/or the second drawing area 822 through an eraser control, and specifically, the controller determines an erasing path from an erasing start point to an erasing end point in response to a sliding operation from the erasing start point to the erasing end point input by the user, and obtains a target drawing area according to coordinates of a pixel point where the erasing start point is located, where the target drawing area is the drawing area where the erasing start point is located; if the target drawing area is the first drawing area 812, storing the coordinates of the pixel points passed by the erasing path into a first operation list, refreshing the first layer according to the coordinates of the pixel points passed by the erasing path stored in the first operation list, and eliminating or replacing the colors of the pixel points passed by the erasing path in the first layer so as to erase the historical drawing track coinciding with the erasing path in the first drawing area 812, namely eliminating or replacing the colors of the pixel points passed by the historical drawing track coinciding with the erasing path in the first drawing area 812; if the target drawing area is the second drawing area 822, storing the coordinates of the pixel points passed by the erasing path into a second operation list, refreshing the first layer according to the coordinates of the pixel points passed by the erasing path stored in the second operation list, and eliminating or replacing the colors of the pixel points passed by the erasing path in the first layer so as to erase the historical drawing track in the second drawing area 822 coincident with the erasing path, namely eliminating or replacing the colors of the pixel points passed by the historical drawing track in the second drawing area 822 coincident with the erasing path.
It should be noted that the eraser control 814 in the first control area 811 can only delete the content in the first drawing area 812, and the eraser control 824 in the second control area 821 can only delete the content in the second drawing area 822. That is, when the user's drawing start point belongs to the first drawing region 812, the eraser control 814 is in the pick-up state, and the user moves the eraser control 814 to delete the content on the touch movement locus of the eraser control 814, and the content in the second drawing region 822 will not be deleted even if the touch movement locus of the eraser control 814 is partially on the second drawing region 822. Similarly, when the user's falling point belongs to the second drawing region 822, the eraser control 824 is in the pickup state, and the user deletes the content on the touch movement locus of the eraser control 824 by moving the eraser control 824, even if the touch movement locus of the eraser control 824 is partially on the second drawing region 822, the content in the second drawing region 822 is not deleted.
In some embodiments, the user can delete the entire contents of the first drawing region 812 by selecting the delete control 815 in the first control region 811. For example, when the user selects the delete control 815, a selection interface as shown in FIG. 8 is triggered, which includes a confirm option and a cancel option, and when the user selects the confirm option, the entire contents of the first drawing region 812 are deleted, while the entire contents of the second drawing region 822 are retained, as shown in FIG. 9.
In some embodiments, in response to a user selecting the deletion control 815 in the first control area 811, the operation contents stored in the first operation list are controlled to be deleted, and the first image layer is refreshed according to the second operation list and the first operation list after the deletion operation, so as to empty all contents in the first drawing area 812 and retain the contents in the second drawing area 822.
In some embodiments, the user can delete the entire contents of the second drawing region 822 by selecting the delete control 825 in the second control region 821. For example, when the user selects the delete control 825, a selection interface as shown in FIG. 10 is triggered, which includes a confirm option and a cancel option, and when the user selects the confirm option, the entire contents of the second drawing region 812 will be deleted, while the entire contents of the first drawing region 812 will remain, as shown in FIG. 11.
In some embodiments, in response to a user selecting the deletion control 825 in the second control area 821, the deletion of the operation contents stored in the second operation list is controlled, and the first image layer is refreshed according to the first operation list and the second operation list after the deletion operation, so as to empty all contents in the second drawing area 822 and retain the contents in the first drawing area 812.

In some embodiments, each time the user selects the restore control 819 in the first control area 811, the display device reads the first restore data set, stores the most recently saved drawing operation data in the first restore data set into the first drawing operation data set, and deletes the drawing operation data in the first restore data set. At the same time, the first image layer is refreshed according to the first drawing operation data set and the second drawing operation data set to display the input contents corresponding to the aforementioned drawing operation data in the first drawing region 812.
In some embodiments, each time the user selects the undo control 828 in the second control area 821, the display device reads the second drawing operation data set, stores the drawing operation data stored in the second drawing operation data set last time into the second restore data set, and deletes the drawing operation data in the second drawing operation data set. At the same time, the input contents corresponding to the aforementioned drawing operation data in the second drawing region 822 are deleted.
In some embodiments, each time the user selects the restore control 829 in the second control area 821, the display device reads the second restore data set, stores the drawing operation data stored in the second restore data set last time into the second drawing operation data set, and deletes the drawing operation data in the second restore data set. Meanwhile, the first image layer is refreshed according to the first drawing operation data set and the second drawing operation data set to input an input content corresponding to the drawing operation data in the second drawing region 822.
It can be understood that, since the first recovery data set is stored in the first operation list, the second recovery data set is stored in the second operation list, and the first operation list and the second operation list are independent from each other, the first recovery data set and the second recovery data set are also independent from each other and do not affect each other.
