Method for presenting force touch screen handwriting input as writing pen featured handwriting

Abstract

The invention provides a method for presenting a force touch screen handwriting input as a writing pen featured handwriting, and belongs to a method for presenting a touch screen handwriting. A speedfeature and a pressure feature other than a tracing point of the touch writing are acquired. The handwriting presentation width of each point is determined according to the two features. The handwriting presentation of two adjacent points on the trace is realized by: inserting n-1 points at equal distances between the two points, linearly inserting n-1 handwriting presentation widths according tothat the handwriting presentation width of the two adjacent points on the trace is n-1 points and, finally, in the n+1 points, for all the adjacent two points, drawing six straight line segments through the two points and four auxiliary points related to "the two points and to the handwriting presentation width and the inclination angle of the handwriting at the two points". The method of the invention solves the problems that the existing touch writing products present a stiff handwriting and the computer writing features are too obvious to reflect the writing pen styles of different writers.

Description

Technical field: [0001] The invention relates to a method for presenting handwriting written on a touch screen, in particular to a method for presenting a single-point trace of writing on a touch screen capable of sensing touch pressure as characteristic handwriting of a type pen. technical background: [0002] With the rapid development of electronic display technology and touch screen technology, force touch display screens (ForceTouch) that can sense touch have begun to be used on interactive computer system equipment, such as: various smart phones and handheld devices. Most of these devices provide the function of handwriting input. As we all know, the handwriting of the existing touch screen writing input is essentially a single-point trajectory sequence, so most of the handwriting input products directly link the trajectory points with straight lines, displaying lines that conform to the input trajectory, and finally display the symbols to be input, different countries...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the touch handwriting input product of the touch screen (Force Touch) that can sense the touch pressure adopts the method of "directly linking the track points with a straight line to display a line conforming to the input track" when writing and presenting. The handwriting is dull, the computer writing features are obvious, and the pen styles of different writers cannot be reflected. A method for presenting the single-point trajectory of the touch screen handwriting input as a handwriting with the characteristics of a pen
