In this work, we will examine the problem of detecting the angular motion of head in effort to build a head-tracking system to control sound. The head motion occurs in X, Y, and Z linear directions and three rotation angles, namely pitch, roll, and yaw. In the past, we had difficulties to detect the rotation angles, especially yaw. Our current work focuses on the detection of rotation angles using a software interface program. The distance between sound source and head, and angular rotation data is collected by the Wii-remote’s built-in optical sensor and three-axis accelerometer. These real-time data will be used as input to our software interface. Results will be used in conjunction with head related transfer function to create the three dimensional sound source effects.
