[0001] The invention relates to the field of electronic whiteboard data erasing, in particular to a method for erasing electronic data based on an electronic whiteboard eraser. Background Art

[0002] With the continuous development of intelligent technology, image recognition technology has also been further improved. The emergence of electronic whiteboards combines data presentation and handwriting functions, which is closer to today's rapidly developing social life. It has begun to be widely used in work and teaching research.

[0003] Currently, there are three types of variable erasing methods in the writing whiteboard: the first is to clear all, with a fast clearing speed, and the erasing method is controlled by the hardware; the second is to select the target color to erase, this method uses color as a partition, one-click selection to clear, and the erasing method is controlled by the system; the third is arbitrary erasing with the device blackboard eraser, this method captures a large range of touch points, and the erasing method is controlled by the properties of the touch device.

[0004] Among the existing methods, the traditional clear all technology is mainly combined. Its disadvantage is that the erasing range is uncontrollable. For example, in the first erasing method mentioned above, it is impossible to select an area for clearing all. In the second method, color is used as a partition for one-click erasing. Only the area where the color is located can be deleted, and it is easy to erase useful information by mistake. The erasing area cannot be changed. For example, in the third method mentioned above, the erasing range area cannot be controlled. The physical properties of the device directly control the size of the erasing area. For users, the erasing effect is not ideal, so it cannot be erased effectively and quickly. Different devices have different properties. Some whiteboards require some preparation before use, such as connecting to a wireless erasing device, which consumes time. Summary of the invention

[0025] In the embodiment of the present application, when operating on the image interface, erasing data depends on the number of touch points and movement trajectory of the finger, and output feedback results can be obtained in a timely and effective manner.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described here. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that for the sake of ease of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them. Example 1

[0027] like Figure 1 As shown, the present application provides a method for erasing electronic data based on an electronic whiteboard eraser, characterized in that a system for improving the speed of erasing data on an electronic whiteboard is applied to a touch-screen electronic whiteboard peripheral device, and the method includes:

[0028] S100: Collecting and acquiring touch data parameters of the access object to obtain a touch data parameter set;

[0029] In the application embodiment, the first touch data parameter and the second touch data parameter are collected as the touch data parameter set. Specifically, the access object refers to a user using a touch-screen electronic whiteboard. When the user touches, the number of touch points is recorded, and when the user slides on the screen, the motion trajectory is recorded.

[0030] Furthermore, the acquisition of the touch data parameters of the access object to obtain a touch data parameter set is performed in the step

[0031] S100 includes:

[0032] S110: acquiring the number of touch points of the access object and generating a first touch data parameter; S120: acquiring the motion trajectory of the access object and generating a second touch data parameter;

[0033] S130: taking the first touch data parameter and the second touch data parameter as the touch data parameter set;

[0034] The number of touch points refers to the position of the touch point calculated by the screen through finger pressing, and the motion trajectory refers to the position where the finger moves after pressing. For example, the resistive screen evaluates the position on the screen based on the data between the calculated force and the current.

[0035] Press and respond, the one-touch technology principle of the resistive screen makes the machine have higher touch accuracy. S200: Collect and obtain the operating parameters of the target object environment and obtain the operating parameter set;

[0036] In the embodiment of the present application, the first operating parameter and the second operating parameter are collected as the operating parameter set. Specifically, the target object environment refers to the entire operating environment of the touch-screen electronic whiteboard.

[0037] Furthermore, the acquisition of the operating parameters of the target object environment is performed to obtain an operating parameter set, step S200

[0038] include:

[0039] S210: Acquire the reference parameters of the target object and generate the first operating parameters;

[0040] S220: Acquire display parameters of the target object to generate second operation parameters;

[0041] S230: Taking the first operating parameter and the second operating parameter as the operating parameter set;

[0042] The comparison parameters refer to the data in the touch-screen electronic whiteboard database used to identify the number of fingerprints corresponding to the operating tools, including but not limited to personal settings, default settings, etc., which have been stored in the touch-screen electronic whiteboard in advance for identifying the number of fingerprints corresponding to the operating tools. The display parameters refer to the image data information currently displayed on the touch-screen electronic whiteboard, the blank image on the whiteboard or the image with information recorded on it. For example, in teaching research, teachers will inevitably make mistakes when annotating or writing on the blackboard. When they choose to erase, they need to obtain the content currently displayed on the touch-screen electronic whiteboard for the convenience of teachers.

[0043] The teacher clears the content, and the display parameters obtained at this time are the image information content currently displayed on the touch-screen electronic whiteboard. S300: matching the touch data parameter set with identification indicators to generate an operation instruction set;

[0044] In an embodiment of the present application, the first operation instruction and the second operation instruction are used as the operation instruction set. Specifically, identification indicator matching refers to converting the data information accessed by the user into an erasable tool. In subsequent operations, traces of movement are identified, and the selected tool is called in the subsequent step to obtain an instruction that the system needs to prepare for execution.

[0045] Furthermore, the touch data parameter set is matched with identification indicators to generate an operation instruction set, and step S300 includes:

[0046] S310: Identify a first touch data parameter according to a first operating parameter to obtain a first operation instruction;

[0047] S320: generating a second operation instruction according to the second touch data parameter;

[0048] S330: taking the first operation instruction and the second operation instruction as the operation instruction set;

[0049] An operation instruction refers to a user accessing a touch-screen electronic whiteboard, combining the user's touch data with a one-to-one comparison within the first operating parameter, traversing all operating parameters until the required parameters are found, and obtaining an instruction that the system needs to prepare to execute. The content of the instruction includes but is not limited to framing regular area erasing, erasing all, etc. For example, in Photoshop, when a user uses the lasso tool to circle a certain position in an image in a layer, the data that needs to be modified or cleared is quickly circled, and the background system identifies the touch data parameters through the operating parameters to obtain instructions for modifying or clearing the information.

[0050] In different environments, the command attributes obtained are not the same. Specifically, the settings can be initialized according to personal usage habits. For example, when used by people with hand disabilities, the settings can be adjusted according to actual conditions. For example, the trigger area of ​​multiple fingers can be changed to obtain different operation instructions according to different triggering methods of single or double fingers. The triggering methods include but are not limited to single-click, double-click, long press, drag, etc. to obtain different operation instructions.

[0051] The second operation instruction refers to when the touch-screen electronic whiteboard recognizes the information of a finger touching the screen, the information is converted into a tool, and the tool moves again according to the trajectory to perform the operation.

[0052] Combining the results of the first and second steps, the judgment signal detection is triggered. The first aspect is to judge based on the number of touch points, and the judgment methods include but are not limited to single finger, double finger, three fingers, etc. When the touch-screen electronic whiteboard is in use, the command can be triggered by multiple fingers and at least one touch point is used for triggering. The second aspect is to make an area judgment based on the motion trajectory of the touch. The judgment methods include but are not limited to the areas formed by erasing trajectories such as circles, rectangles, and irregular shapes. When the touch-screen electronic whiteboard is in use, after following the tool selected in the first aspect, the trajectory formed by the sliding operation is the motion trajectory guiding the tool selected in the first aspect.

[0053] S400: Generate an output parameter set according to the operation parameter set and the operation instruction set;

[0054] In an embodiment of the present application, the operation parameter set is collected and traversed, and the first output parameter and the second output parameter are combined to generate an output parameter set. Specifically, the traversal is to visit each node along the route in the initial data set in the database, and overwrite the operation instruction set with a new image.

[0055] Furthermore, the running parameter set and the operation instruction set generate an output parameter set, and step S400 includes:

[0056] S410: Generate a first output parameter according to the operation parameter set and the operation instruction set;

[0057] S420: Using the first output parameter as the current output parameter, and generating a second output parameter according to the operation parameter set and the operation instruction set;

[0058] S430: traverse the operation parameter set, combine the first output parameter and the second output parameter, and generate an output parameter set;

[0059] Output parameters refer to the feedback of the results of the operation to the touch-screen electronic whiteboard after the instruction information is read and executed by the system. Because the actual operation is continuous, each time a new step is generated, the image is constantly overwritten. For example, in some photo editing software, when the user adjusts the image parameters, the image output is fed back to the user. When the picture is opened, the default data on the picture is the initial value. When our hands operate, the image will change accordingly. We can read the information intuitively, which is the result fed back to us after the operation is executed.

[0060] The first output parameter is superimposed. The result of the first command being overwritten and superimposed is used as the current output state. Subsequent instructions are continuously overwritten and superimposed until all instructions are executed.

[0061] All command executions are accessed and executed at each node, and each output result is used as the current output image of the next execution. These generated images are collected together to form an animation process, and the complete animation process is output as a command, which makes it easier for users to read it in a timely and smooth manner and avoids delays and freezes in the screen.

[0062] S500: Outputting the output parameter set to the external touch-screen electronic whiteboard device;

[0063] In the embodiment of the present application, the data result of the output parameter set is output to an external touch-screen electronic whiteboard device and fed back to the access object. Further, the output parameter set is output to the external touch-screen electronic whiteboard device. For example, when reporting on a job, the PPT presentation is projected onto a blank screen. When the presenter finds that the presentation is insufficient in some places during the presentation, the presenter makes timely modifications on the whiteboard, and the file projected onto the screen is also modified accordingly, so that everyone can continue to browse.

[0064] Based on the same inventive concept as the method for erasing electronic data based on an electronic whiteboard eraser in the aforementioned embodiment, Figure 4 As shown, the present application provides a device for improving the speed of erasing data on an electronic whiteboard, wherein the device for erasing electronic data based on an electronic whiteboard eraser comprises:

[0070] Furthermore, the device also includes:

[0071] A third obtaining unit collects and obtains the number of touch points of the access object to generate a first touch data parameter;

[0072] A fourth obtaining unit, which collects and obtains a motion trajectory of the access object and generates a second touch data parameter;

[0073] The fourth processing unit uses the first touch data parameter and the second touch data parameter as the touch data parameter set.

[0074] Furthermore, the device also includes:

[0075] The fifth obtaining unit collects and obtains the control parameter of the target object to generate the first operating parameter.

[0076] The sixth obtaining unit collects and obtains display parameters of the target object to generate second operating parameters.
