Human computer interface virtual acoustic display using gyroscopic sensors

In the paper the spherical-head model for the HRTF is developed and is used in conjunction with yaw angle tracking provided using software developed for a WiiRemote controller to simulate sound radiated from a point source as a function of head position. The yaw rotation angle is evaluated using gyros supplied in the Wii motion plus extension device. The real-time data obtained is used to control the parameters of the head related transfer function. This work aims to bring affordable experimental platforms for educating students in physical acoustics and signal processing.
