针对手势交互中手势信号的相似性和不稳定性,在研究了加速度传感器MMA8452Q的基础上,设计并实现了一种基于三轴加速度传感器的手势识别方案。该系统利用MMA8452Q传感器采集手部倾斜角度信号,通过IIC连接方式将采集到的数据传送到单片机STC89C52RC,单片机STC89C52RC对接收到的数据进行分析处理,最后输出相对应的控制信号,可以用来实现肢体动作控制家电。测试结果表明：系统测量精度高、运行稳定,实时性好、性价比高,具有一定的实用价值。

Aiming at similarity and instability of gesture activity signal in gesture interaction,a gesture recognition scheme based on three-axial accelerometer Freescale MMA8452Q is designed and realized. The system uses the MMA8452Q chip to collect the hand tilt angle signals,then transmits the data to the MCU STC89C52RC through the IIC bus,the MCU STC89C52RC analyzes and processes the sig-nals,then outputs the final corresponding control signals,which is used to implement gesture for home appliances controlling. The test re-sult shows that this system has high measuring accuracy,stable operation,good real-time and high performance-price ratio,with certain practical value.
