Touch operation response method, system and touch screen terminal

Abstract

The present invention is applicable to the technical field of touchscreens, and provided is a touch operation response method. The method comprises the following steps: on a touch operation track on which a touch point Pi performing noise reduction processing currently is located, taking two touch points Pi-1 and Pi-2 which are closest to the touch point Pi in sequence before the touch point Pi, taking several adjacent touch points Ni,..., Ni+m in sequence after the touch point Pi, and making a ray along a direction from the touch point Pi-2 to the touch point Pi-1; calculating distances from the touch points Ni,..., N1+m to the ray respectively and a coordinate of a first reference touch point Pi'; calculating a coordinate of a second reference touch point Pi"; according to the first reference touch point Pi', the second reference touch point Pi", and the closest touch points Pi-1 and Ni at the two sides, calculating a coordinate of the touch point Pi after the noise reduction processing; and responding to a touch operation of a user on the touch point Pi at the coordinate of the touch point Pi after the noise reduction processing. The present invention can truly restore a touch operation on a touchscreen, so that a curve of the touch operation is smoother.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a touch operation response method, system and touch screen terminal. Background technique [0002] Capacitive touch screens are increasingly used in many electronic products. The reliability, stability and resolution of the touch detection results depend on the accuracy and stability of the touch detection data, regardless of the type of application and the touch detection method. The detection device will encounter interference in actual use. In many cases, noise interference will bring large errors to the touch detection data, affect the stability and resolution of the touch detection results, and even cause false touch and touch out-of-control detection results in severe cases. [0003] Such as figure 1 As shown, when "2" is input on the touch screen, due to the influence of noise, the touch screen points will not be able to form a continuous and smooth cur...

Problems solved by technology

In many cases, noise interference will bring large errors to the touch detection data, which will affect the stability and resolution of the touch detection results. In serious cases, it may even lead to false touch and touch out of control detection results.

[0003] like figure 1 As shown, when inputting "2" on the touch screen, due to the influence of noise, the touch screen points will not be able to form a continuous and smooth curve, resulting in local distortion, which cannot be applied to capacitive touch screen systems that require a higher signal-to-noise ratio.
