JIN Chun;JIA Zhen-mei;Wireless Transmission Key Laboratory,School of Communication & Information Engineering,Chongqing University of Posts & Telecommunications;Chongqing Jinou Science&Technology Development Co,Ltd;  
With the development of wearable receiving equipment,input devices matching which require more portable and miniaturization. So a wearable input system was designed,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%.
