gesture recognition device based on FDC2214

Abstract

The invention belongs to the technical field of man-machine interaction, and particularly relates to a gesture recognition device based on FDC2214. The gesture recognition device comprises an MSP430G2553 master control unit, an FDC 2214 capacitive sensor detection unit and a man-machine interaction unit. And the main control unit adopts an MSP430G2553 chip and comprises a power supply circuit, a clock crystal oscillator circuit and a reset circuit which are used for ensuring the normal operation of the processor. The power supply circuit is provided with a ground filter capacitor at the inputend and the output end of the voltage stabilizing chip so as to provide stable 3.3 V voltage for the whole device. The clock circuit comprises a low-speed crystal oscillator circuit, and the low-speedcrystal oscillator is used when the main control unit sleeps. The defects that in the prior art, the cost is high, the algorithm is complex or the accuracy and the stability are reduced due to the influence of the external environment are overcome, and after a user is temporarily trained, the recognition accuracy is high, and the recognition speed and the stability are very high.

Problems solved by technology

The recognition distance of the infrared tube solution depends on the performance of the infrared tube, and the infrared tube has a great influence on the light intensity, which will seriously affect the performance and stability. This solution has not been fully adopted

The gesture recognition scheme based on the inertial sensor mainly uses the accelerometer and the gyroscope to obtain the motion state information of the hand, so as to judge the gesture. It can only be recognized by wearing a specific device on the hand, so the scope of application is greatly limited
