A Study of Audio Interactive Device Design with Microphone Array and Applications

[[abstract]]Music and dance are inseparable, generally, dancers use their body movement to present music's content and emotion; However, if the presentation of music is decided by dancer's body movement, that could make music and dance has another interactive relationship. The purpose of this study is to develop an audio interactive device. In the part of input, we use microphone array as interactive device to capture the sound signal of user’s steps, and use step recognition and triangulation to recognize user steps' tempo and location. In the part of output, the different tempo of user's stepping will change the tempo of MIDI music, and the different location of stepping will make MIDI music different mixed content. By the development of this device, offering a wearless way to make interaction between human and machine. User can display the music immediately match up with his body movement, achieving a real-time interactive music device.
