Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] figure 1 As shown, it is a control flow chart of the method for preventing false triggering of the pressure button implemented by the lock of the present invention. In the figure, the steps for realizing the lock of the present invention are:

[0025] 101) Confirm that the pressure key triggers the effective circle position and the number of sensors used is N+1 (N>=3).

[0026] combine figure 2 As shown, according to the requirements of the pressure button, the effective trigger position of the button is specified (that is, the button function can only be responded to when the pressure is...

Abstract

The invention discloses a method for preventing false triggering of a pressure button. The method comprises the following steps: determining a valid triggering position of the pressure button and the number of sensors; determining valid positions of the sensors, measuring pressure values corresponding all the sensors; judging whether a pressure is applied or not and determining whether a triggering position of the pressure button is at the valid position or not; and executing a corresponding operation according to a result. Through adoption of the method, whether the applied pressure is a real touch control pressure or not can be judged accurately; the problem of false triggering of the pressure button in an invalid pressing area is solved; a valid pressing area is controlled accurately; and the performance and practicability of the pressure button are improved greatly.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a method for preventing false touches of pressure keys. Background technique [0002] With the rapid development of smart electronic devices, pressure touch technology has appeared in mobile phones, smart watches, notebooks and home appliances, and has a trend of widespread popularization. However, in the application of pressure buttons, there are situations where it is easy to trigger by mistake. [0003] For example, patent application 201610166341.5 discloses an AD key confirmation method and device and electronic products, the AD key confirmation method includes: obtaining the AD key sampling value during a key press process; calculating the maximum and minimum of the acquired AD key sampling values Value difference; compare the calculated difference with the preset threshold, if the difference is greater than the preset threshold, it is determined that the number...
