Touch operation response method, system and touch screen terminal

Abstract

The invention is suitable for the technical field of touch screens and provides a touch operation response method. The method comprises the following steps: on a touch operation track where a touch point Pi subjected to noise reduction treatment currently is located, a touch point (Pi-1) and a touch point (Pi-2) which are most adjacent to the touch point Pi are taken sequentially before the touch point Pi, a plurality of adjacent touch points from a touch point Ni,..., to a touch point (Ni+m) are taken sequentially after the touch point Pi, and a radial ray is made in a direction from the touch point (Pi-2) to the touch point (Pi-1); distances from the touch point Ni, ..., and the touch point (Ni+m) to the radial ray are calculated respectively, and the coordinate of a first reference touch point Pi' is calculated; the coordinate of a second reference touch point Pi' is calculated; the coordinate of the touch point Pi after the noise reduction treatment is calculated according to the first reference touch point Pi', the second reference touch point Pi', as well as the touch point (Pi-1) and the touch point Ni which are most adjacently located on two sides; and the touch operation for the touch point Pi by a user is responded in the coordinate position of the touch point Pi after the noise reduction treatment. According to the invention, the touch operation on the touch screen can be truly restored, so that the 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] like 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 curve,...

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.
