Effect of phase difference of ear motions on direction detection performance.

In the upper panels, blue line indicates the left ear’s orbit given by , and orange line does the right ear’s orbit , respectively. Black straight lines connect simultaneous points of the left and right ears’ orbits with the phase difference ΔΦ. In particular, the ear motion with ΔΦ = 180° is [, , ] and the ear motion with ΔΦ = 0° is [, COS, SIN]. For motions with ΔΦ between 45° and 180°, good-quality direction detection performance is achieved.
