Abstract

The invention relates to the field of communication and discloses an ultrasonic gesture recognition method and device. In the present invention, the ultrasonic gesture recognition method comprises steps of: acquiring a gesture feature by using an ultrasonic signal processing mode; optimizing the acquired gesture feature; and recognizing the optimized gesture feature. The invention also discloses an ultrasonic gesture recognition device comprising: a first acquisition module for acquiring the gesture feature by using the ultrasonic signal processing mode; an optimization module for optimizing the acquired gesture feature; a recognition module for recognizing the optimized gesture feature. Compared with the prior art, the method and device can secondarily extract and optimize the acquired gesture feature so as to achieve high accuracy of the acquired gesture feature and help to improve the recognition rate of the gesture feature.

Description

technical field [0001] The invention relates to the communication field, in particular to an ultrasonic gesture recognition method and device. Background technique [0002] In recent years, with the continuous development of communication technology and the continuous advancement of science and technology, mobile terminals such as mobile phones or notebook computers have become indispensable tools in people's daily life; Brings great convenience. Moreover, the functions of mobile terminals are becoming more and more powerful, and have gradually penetrated into people's lives. [0003] At present, many terminal devices on the market realize gesture recognition through ultrasonic waves, and then realize operations corresponding to gestures. However, the accuracy of gesture recognition in the prior art is relatively low. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a method and device for ultrasonic gesture recogn...
