Abstract

The invention discloses a handwriting track drawing method and device. The handwriting track drawing method comprises the steps that a central processing unit receives a plurality of touch events responding to handwriting input; the central processing unit generates a track point sequence according to the touch events; the central processing unit sends a drawing instruction and a track point sequence to the graphic processor; and the graphic processor draws the handwriting track according to the track point sequence in response to the drawing instruction. According to the handwriting track drawing method and device, the handwriting track can be quickly drawn, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a handwriting trajectory drawing method and device. Background technique [0002] Existing devices increasingly adopt touch mode for human-computer interaction, such as smart phones, vehicle infotainment systems, and so on. Devices that use touch for human-computer interaction generally have a touchpad for user input and a display for displaying user input. When the user performs handwriting input on the touch panel, the user's handwriting track will be displayed on the display to give feedback to the user's input. If the time interval from the user's handwriting input to the display of the handwriting track is relatively long, the user will feel that the handwriting is not smooth, and the user experience is not good. In order to improve the user experience, it is necessary to shorten the time interval between displaying the handwriting track on the display and the han...
