基于穿戴式输入系统的手指敲击识别算法

随着穿戴式接收设备的发展,与其配套的输入设备也要求更加便携和小型化.基于此,设计了一款穿戴式输入系统,系统包括十个指环,指环上集成有MEMS传感器、微处理器、蓝牙通信模块、电池.操作者佩戴该指环键盘通过惯性传感器检测手指的敲击动作,并根据设定的输入法实现文本的输入.另外,针对该系统操作的特点,还提出一种手指敲击识别算法,以实现对敲击动作的识别,通过验证,该算法可实现96％以上的敲击识别率.

Finger Tapping Recognition Algorithm based on Wearable Input System

With the development of wearable receiving equipment, input devices matching which require more portable and miniaturization. So a wearable input system was designed in the paper, the system consists of ten rings integrated with MEMS sensor, microprocessor, Bluetooth communication module and battery. Figure tapping movement was detected by inertial sensors on the ring and text input was implemented according to the text input method. In addition, according to the characteristics of the system operation, in order to realize the recognition of percussion action , a finger tapping recognition algorithm was presented, through the verification, the rate of recognition is more than 96%.
