Handwriting report point prediction method

Abstract

The invention discloses a handwriting report point prediction method, which comprises the following steps: S1, acquiring handwriting data of a plurality of original report points generated during real-time writing, and forming an original sequence seqY by the original report points according to a generation sequence of the original report points, the handwriting data of the original report points including coordinates x, coordinates y and timestamps t for generating the report points; s2, performing duplicate removal on report points in the original sequence seqY to obtain a prediction sequence seqP; and S3, performing parameter setting and feature judgment on the obtained prediction sequence seqP, and obtaining single prediction time pt and the number n of original report points required by single prediction according to a feature judgment result. According to the method, the position to be drawn by the handwriting pen can be predicted through the report point coordinate information and characteristics of the handwriting, and the predicted report point is drawn in advance, so that the difference between the point displayed on the screen and the actual position of the handwriting pen is reduced, the handwriting input becomes smoother, the delay is lower, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of handwriting prediction, in particular to a method for predicting handwriting reporting points. Background technique [0002] At present, more and more tablet computers have a stylus, which supports handwriting input (meeting minutes, drawing graffiti), which improves the convenience and fun of people's daily note-taking and communication. However, due to delays in hardware report transmission and software rendering, there will be a certain distance between the strokes displayed on the screen and the actual position of the pen tip during the writing process. Such delays and distances prevent the strokes from being displayed on the screen in real time, which in turn leads to a poor writing experience for users. Contents of the invention [0003] The purpose of the present invention is to provide a method for predicting handwriting reporting points, which can predict the place where the stylus will draw t...
