[0127] refer to Figure 8 , Figure 8 It is a schematic flowchart of the second embodiment of the pressure sensor-based key recognition method of the present invention. Based on the first embodiment of the above pressure sensor-based key recognition method, the step S30 includes:

[0128] Step S31, when the pressure difference is less than or equal to the first threshold, comparing the second pressure value with a preset second threshold;

[0129] Step S32, if the second pressure value is greater than or equal to the second threshold, then determine that the second sensing area is accidentally touched;

[0130] Step S33 , if the second pressure value is less than the second threshold value, perform key recognition according to the pressing time of the first sensing area and the pressing time of the third sensing area.

[0131] When the pressure difference is less than or equal to the first threshold, the mobile terminal compares the second pressure value with a preset secon...

Abstract

The invention discloses a keystroke identification device based on a pressure sensor. The keystroke identification device based on the pressure sensor comprises a detection module, a comparison module and an identification module, wherein the detection module is used for obtaining a first pressure value in a first induction area of the pressure sensor, a second pressure value in a second induction area of the pressure sensor and a third pressure value in a third induction area of the pressure sensor; the first induction area, the second induction area and the third induction area are sequentially arranged adjacently; the comparison module is used for calculating a pressure difference value between the first pressure value and the third pressure value and comparing the pressure difference value with a preset first threshold value; and the identification module is used for identifying a keystroke according to the second pressure value when the pressure difference value is less than or equal to the first threshold value. The invention further provides a keystroke identification method based on the pressure sensor. According to the invention, the keystroke identification accuracy based on the pressure sensor is greatly increased; and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a pressure sensor-based key recognition device and method. Background technique [0002] With the rapid development of communication technology and terminal technology, terminals such as mobile phones, smart phones, notebook computers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), and PMPs (Portable Multimedia Players) are more and more widely used. Because large-screen mobile terminals are more suitable for various entertainment activities such as watching movies and playing games, the display area of ​​existing mobile terminals is getting larger and larger, and the button area of ​​mobile terminals is also getting smaller and smaller. It is becoming more and more difficult to recognize the keys. Because the existing pressure sensor-based keys only obtain pressure values ​​through two pressure sensing areas, the key recognition is performed according to t...
