Using RFID to realize human computer interaction

This paper proposes a human computer interface which is based on Radio frequency identification (RFID) technique to let human communicate with computer by analyzing the signal from tags. For retrieving those signals from tags, how to decreasing the noises created by surrounding environment and detecting useful information from variant signals are the most important. In our proposed method, we adopt a train procedure as pre-processing to categorize all of signals into two categories: noise and real data. After the real data is retrieved, we use "music director" as an application to let user play with computer. The experimental results show the proposed method can analyze the signals from tags successfully with high detection rate.
