Abstract: Techniques include providing a user with a set of loudspeakers on a sphere and playing back sound from the set of loudspeakers one at a time. For each loudspeaker, the user points in a direction at which the user perceives the sound. The HRTF corresponding to a new direction based on the perceived direction is used instead, or the original HRTF at the perceived direction is used. In some implementations, the new direction is obtained from the perceived direction via a barycentric mapping. In some implementations, a difference between the new direction and the perceived direction is equal to a difference between the perceived direction and the original direction.
