基于LC谐振腔传感器的简易手势识别系统

Simple Gesture Recognition System Based on LC Resonator Sensor

近年来,手势识别在体感交互、康复训练等各行各业发挥了重要应用。本文在前人的基础上提出了一种基于LC谐振腔传感器的简易手势识别系统,本系统采用MSP430F5529单片机为控制器,通过定制覆铜板与电容式近距离传感芯片FDC2214实现接近检测手势信号,并由I2C接口将测得的数据回传给单片机进行滤波、特征提取、模式分析等操作,进行手势的训练或判定。通过对猜拳模式和划拳模式的测试发现,本装置可以方便高效地识别出简单手势,成功率高。

In recent years,gesture recognition has played an important role in somatosensory interaction and rehabilitation training.In this paper,on the basis of previous studies,we propose a new method based on LC,the system uses MSP430F5529 single chip microcomputer as the controller,realizes the close detection of gesture signal by customizing copper clad laminate and capacitive proximity sensor chip FDC2214,and sends the measured data back to the single chip microcomputer for filtering,feature extraction,pattern analysis and other operations by I2C interface,so as to train or judge the gesture.After testing,the device can realize simple gesture recognition in a short time,and meet the design requirements.
