Touch control method

Abstract

The invention relates to a touch control method. Two detection units are arranged in a touch screen unit and used for detecting vibration caused by touching a function or program selecting operation area by a user, respectively detecting propagation time for propagating a vibration wave of a vibration point to the two detection units or propagation distances from the vibration wave of the vibration point to the two detection units, and sending detected numerical values to a control unit simultaneously; and the control unit receives the numerical values which are sent by the two detection units, compares the numerical values with standard numerical values which are pre-stored in a storage unit, and finds coordinate information which corresponds to the vibration point, so the specific position and corresponding functions or programs of an operation point of the user are determined, corresponding response is carried out, and setting of the functions or the programs is realized. By the method, the touching mode of vibration detection is completely realized; influence of an electric field on interference of the method is avoided; detection precision is high; and the method is very convenient to use.

Description

Technical field [0001] The invention relates to a touch control method, belonging to the technical field of touch screen control. Background technique [0002] At present, touch screens are commonly used as display and operating devices in various fields such as household appliances. The touch screen is basically divided into function selection touch area and program selection touch area. The touch screen is connected to the control unit. The user selects and operates the place according to needs and prompts on the touch screen. The required functions or procedures to complete all required tasks. According to different touch control methods, the currently commonly used touch screens are basically divided into two types, one is a capacitive touch screen and the other is a resistive touch screen. [0003] For capacitive touch screens, when a finger touches the screen, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitanc...

AI Technical Summary

Problems solved by technology

[0005] Whether it is a capacitive touch screen or a resistive touch screen, it is more susceptible to interference from electric fields, which in turn affects its use effect and detection accuracy

In addition, for the capacitive touch screen, since the human body becomes a part of the circuit, the drift phenomenon is more serious, and it will no longer work after wearing gloves, so the use is greatly restricted.
