Step 33: Form the movement track of the touch point according to the position information, and judge whether it moves, if yes, the touch screen displays and draws the track of the touch point; otherwise, the touch screen displays the touch point in ink Control point of the stay point, and enter the step 5;

Step 34: Automatically select related information blocks before and after the touch point, display the information blocks in the floating window, and enter the step 5;

Step 4: switch the operation mode according to the touch point information;

Step 41: Enter the pan zoom mode or screenshot mode according to the touch time; if the touch time is less than the mode judgment time, enter the pan zoom mode; otherwise, enter the screenshot mode and enter step 43:

Step 42: Generate a movement trajectory according to the position information of the touch point, judge whether the moving directions of the touch points are the same according to the movement trajectory, if they are the same, the page is translated according to the movement trajectory, otherwise according to all The position information of the touch point determines whether to enter the proportional scaling mode or the free scaling mode; when the distribution of the touch points is greater than or equal to three, enter the proportional scaling mode; otherwise, enter the free scaling mode , using the orientation of the touch point as the change axis to freely zoom and change, complete the zoom according to the change of the touch point, and enter the step 5;

Step 43: A screenshot frame appears in the drawing area of the touch screen, and the border position of the screenshot frame is changed by sliding a single touch point to complete the screenshot;

Step 5: Whether there is the touch point information on the touch screen at present, if there is the touch point information, return to the step 2, otherwise the operation is completed.

Preferably, the touch point information in the step 1 includes touch point number, touch time and position information.

Preferably, the translation process is to form a straight line according to the motion trajectory of the touch points, judge the direction of motion according to the straight line, and realize the multi-touch operation by sliding all the touch points in the same direction in a continuous straight line. The state pans up, down, left, and right.

Preferably, the proportional zoom mode is to zoom in or out of the page through the distance changes of the motion tracks of all the touch points, and when the touch points leave the touch screen, the page remains on the The last changed state of the touch point.

An electronic device screen operating system, including a data acquisition module, a touch point judgment module and a mode switching module;

The mode switching module switches the current operation mode according to the judgment result, and generates a movement trajectory according to the touch point information, and executes the current operation mode according to the movement trajectory.

It can be seen from the above-mentioned technical solutions that, compared with the prior art, the present invention discloses an electronic device screen operating system and method, including a data acquisition module, a touch point judgment module and a mode switching module. The detection and collection of the upper touch point, judge the user's intention through the touch point judgment module, judge the page operation that needs to be switched according to the number of touch points, touch time and position information in the touch point information, and execute it through the mode switching module page operations. Enter the handwriting mode when it is single-touch, and then judge whether it is in the writing state or select the writing text in the floating window display state according to the touch time. When in the writing state, the motion track is generated according to the position information, so that the writing line is generated according to the motion track. Display; when it is multi-touch, it is the page operation mode. If all the touch points move in the same direction, the page will be translated. When the touch points move in the opposite direction, the page will be zoomed out. At the same time, according to the different distribution positions of the touch points, it can automatically choose whether to perform proportional scaling or free scaling. When the distribution orientation of the touch points is greater than or equal to three, it will be proportional scaling. Height scaling, width scaling when distributed on the left and right of the page. Therefore, the present invention implements page operation switching based on the information of touch points on the touch screen according to simple gestures, avoids the cumbersomeness of clicking menu switching and reduces the misoperation rate, and makes the use of electronic devices easier and faster.
