Pressure simulation algorithm for non pressure sensitive touch screen

Abstract

The application of non pressure-sensitive touch screens in smart tablet software is becoming increasingly widespread, but they cannot directly sense pressure, which limits the user's writing experience.  This article proposes a pressure simulation algorithm based on gestures and speed, which simulates pressure by analyzing touch data.  This algorithm identifies the user's touch gestures and speed changes, infers the corresponding pressure values, and maps them to simulated pressure data.  The experimental results show that the algorithm can significantly improve the writing performance of non pressure-sensitive touch screens, making the user experience more natural and smooth.
