Problems solved by technology

[0005] In the process of using the touch screen for input, when the palm or face with a large area touches the resistive touch screen or is close to the capacitive touch screen, it is easy to trigger the touch screen, so that the hand-held device will cause misoperation without the user's knowledge.
For example, when answering a call, if the mobile communication terminal is too close to the face, the face may trigger the hang-up key on the touch screen, so that the call is hung up without the user's knowledge, and the result is that the user's normal life is affected. call

Abstract

The invention discloses a triggering method of a touch screen, a touch device and a handheld device, relating to the technical field of information input and aiming to prevent false triggering of the touch screen. The triggering method of the touch screen comprises the following steps of: comparing random figure parameters which are generated by touch input with standard figure parameters which are stored in advance; receiving the touch input and executing corresponding operation according to the touch input if the comparison result of the random figure parameters and the standard figure parameters is in a preset range; and locking the touch screen if the comparison result of the random figure parameters and the standard figure parameters exceeds the preset range. The invention can be used for preventing false triggering of the touch screen.

Description

technical field [0001] The invention relates to the technical field of information input, in particular to a touch screen trigger method, a touch device and a handheld device. Background technique [0002] With the development trend of convenience and miniaturization of handheld devices, higher requirements are put forward for the input configuration of handheld devices. Among them, the touch screen has been widely used as an input device that occupies a small volume, is easy to use, and can accept multi-point input (such as pressing the shift key and the letter key simultaneously to switch between upper and lower case). [0003] In a handheld device with a touch screen, touch input is generally generated by pressing a finger or a stylus. Compared with key input, less force is required when using a touch screen for input, especially for a capacitive touch screen (where the touch screen includes several types of resistive touch screens and capacitive touch screens), fingers ...
