Abstract

A method and a system for estimating the tendency of pressure change on a touch panel are disclosed. The method includes: getting first left-image data and first right-image data by using a left image-capturing device and a right image-capturing device at a first time, respectively; calculating first estimation pressed-area parameter according to the first left-image data and the first right-image data; getting second left-image data and second right-image data by using the left image-capturing device and the right image-capturing device at a second time, respectively; calculating second estimation pressed-area parameter according to the second left-image data and the second right-image data; and compare the first estimation pressed-area parameter with the second estimation pressed-area parameter.

Description

technical field [0001] The invention relates to a method for estimating pressure changes; in particular, to a method for estimating pressure changes of a touch screen. Background technique [0002] With the rapid development of science and technology, more and more touch products appear in our daily life. Looking at the smart phones, digital cameras, computers and TVs currently on the market, all of them are characterized by touch functions. one. However, users often have expectations when touching the screen, thinking that the screen should have a specific physical reaction after being touched, for example, the screen will sink while pressing. [0003] In order to solve this problem, in the past, visual or auditory effects were used to assist, such as the visual effect that the screen sinks while pressing, or the auditory effect that produces the sound effect of the button, so that the user can have the feeling of interacting with the screen. [0004] However, touch is a ...
