CIRCULAR SELECTION METHOD AND DEVICE FOR HANDWRITTEN CHINESE CHARACTERS, TOUCH APPARATUS, AND READABLE STORAGE MEDIUM

摘要

A circular selection method and device for handwritten Chinese characters, a touch apparatus, and a readable storage medium. The circular selection method for handwritten Chinese characters comprises: monitoring a circular selection operation performed on target handwriting on a display interface (S21); connecting touch points detected during the circular selection operation, and generating an enclosed motion trajectory corresponding to the circular selection operation (S22); determining, according to a point of intersection between a straight line corresponding to each handwriting point of the target handwriting and the enclosed motion trajectory and a trajectory angle corresponding to each of the points of intersection therebetween, whether each handwriting point is located within the enclosed motion trajectory, wherein the straight line corresponding to each handwriting point is a straight line passing through the handwriting points (S23); determining, according to the calculated number of handwriting points located within the enclosed motion trajectory, whether the target handwriting is located within the enclosed motion trajectory (S24); if it is determined that the target handwriting is located within the enclosed motion trajectory, encircling and selecting the target handwriting (S25). The method reduces user difficulty in selecting a handwritten Chinese character on a screen, thereby improving user experience.
