Identification and operation method of touch screen interface gestures

Abstract

An identification and operation method of touch screen interface gestures comprises the following steps: 1) gesture input used for acquiring gesture data input by a user through a touch screen, 2) gesture identification, and 3) operation instruction execution used for executing an operation instruction corresponding to the gesture data, wherein step (1) comprises the following steps: 11) reminding the user to input a gesture; 12) judging whether the user inputs the gesture, and entering step 13) if the user inputs the gesture, otherwise, transferring to step 11); and step 13) acquiring the gesture data of the touch screen. The identification and operation method matches a response action by identifying the features of graphic symbols input by a user instead of clicking on a quite small screen area; therefore, the method has strong tolerance on user input and has no requirements on the specific input position of the user; the method can identify similar graphic symbols input by the user, thereby increasing equipment accessibility; moreover, the method can establish and expand a graphic database by identifying and studying graphics input by the user.

Description

technical field [0001] The invention relates to a touch screen interface gesture recognition operation method. Background technique [0002] Most of today's embedded devices use touch screens as the main input device. In existing touch screen applications, the system first obtains the coordinates of the touched position, and then judges the area to which the coordinates belong to determine which operation should be triggered. This approach has the following disadvantages: [0003] 1. The click position must accurately fall into the judgment area to trigger the correct operation; [0004] 2. Limited by the size of the screen, the judgment area cannot be very large. Prone to inaccurate problems; [0005] 3. Due to the relatively large human fingers, the error rate will be very high when operating with fingers, and the usability is not good; [0006] 4. Today's embedded devices have many functions. Different users have different concerns. Therefore, the commonly used fun...
