A key trigger method and device

Abstract

The invention discloses a key trigger method. The key trigger method comprises the following steps: obtaining distance data and light intensity data detected in a key touch area in real time; when detecting that both of the distance data and the light intensity data are smaller than a preset threshold, sending a key trigger signal to a wearable device, thus allowing the wearable device to process according to the key trigger signal. Correspondingly, the invention further discloses a key trigger apparatus. By adopting the key trigger method and apparatus disclosed by the embodiments of the invention, the key trigger accuracy can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a key trigger method and device. Background technique [0002] In the wearable device in the prior art, the operation of the wearable device by the user is generally implemented by placing physical buttons. However, if ordinary physical buttons are used, the gap between the button and the main body of the wearable device will lead to poor waterproof ability of the wearable device, which will lead to the failure of the button function. Moreover, the pressing height and mechanical height of the physical button have certain requirements. As a result, it occupies a large structural space. In addition, existing wearable devices also have capacitive buttons. However, due to the inherent characteristics of capacitive sensing, when the capacitive key is exposed to water, the surface is wet, which may easily cause misoperation of the key.
