Gesture recognition system and gesture recognition method

Abstract

The invention relates to a gesture recognition system and a gesture recognition method. The gesture recognition system comprises a left sound source, a right sound source, a signal collecting module and a gesture analysis module, wherein the left sound source and the right sound source are horizontally placed at intervals and used for sending sound signals to a gesture detecting region, the signal collecting module is placed on a perpendicular bisector of a connecting wire of the left sound source and the right sound source and used for receiving sound signals sent from the left sound source and the right sound source and translating sound signals into audio signals. The gesture analysis module is used for receiving and analyzing the audio signals output from the signal collecting module and ensuring gesture and outputting instructions. The gesture recognition system and the gesture recognition method have the advantages of being small in calculating amount, low in misjudgment rate and free of relying on light. Non-contacted instrument output of a computer can be achieved on a personal computer, a notebook computer, a tablet computer and other mobile devices through a loudspeaker and a microphone.

Description

【Technical field】 [0001] The invention relates to the field of gesture recognition, in particular to a gesture recognition device and a recognition method. 【Background technique】 [0002] With the continuous development of personal electronic products, the way people interact with electronic devices is also constantly changing, from keyboard input at the beginning to touch input, and now a new non-contact gesture recognition human interaction mode has emerged. [0003] Currently popular gesture recognition methods include video-based gesture recognition and voice-based gesture recognition. Gesture recognition based on video has disadvantages such as large amount of calculation, high rate of misjudgment, and requirements for lighting. However, voice-based gesture recognition captures a group of voice information obtained through the speech process such as keywords, which requires the accuracy of human pronunciation and the need to remember voice commands and other defects. ...
