Abstract

The present application provides a terminal device and a pressure touch method. The terminal device includes: a cavity formed by a touch screen and a housing, an air pressure sensor and a processor, and the air pressure sensor is arranged in the cavity for being pressed on the touch screen or the housing. During operation, the air pressure in the cavity is detected, and the processor is used to determine the pressure of the pressing operation according to the air pressure change value and one or more pressure calculation coefficients, wherein the one or more pressure calculation coefficients include a deformation coefficient corresponding to the position of the pressing operation , the deformation coefficient is a coefficient indicating the amount of deformation of the screen. By using the change value of the air pressure in the cavity to determine the pressing force of the user on the terminal device, there is no need to increase the volume of the terminal device, and the cost of the terminal device is reduced.

Description

technical field [0001] The present application relates to touch screen control technology, in particular to a terminal device and a pressure touch method. Background technique [0002] With the increasing popularity of smart electronic devices, human-computer interaction technology innovations emerge in an endless stream. For example, many electronic devices using touch screens adopt forch touch technology. Electronic devices using forch touch technology can sense the strength of light pressure and heavy pressure, and call out different corresponding functions, enriching people's understanding of electronic devices. Operation method. [0003] At present, the technologies for detecting the user's pressing pressure on electronic devices are mainly divided into capacitive, resistive and piezoelectric. In the capacitive solution, two layers of capacitive sensors are arranged under the touch screen of the electronic device. When the user presses the touch screen, the touch scre...
