“Hanger reflex”:A reflex motion of a head by temporal pressure for wearable interface

When a head is equipped with a clothes hanger made of wire sideways, and its temporal region is sandwiched by the hanger, the head rotates unexpectedly. Although this phenomenon is widely known, the mechanism that underlies this phenomenon is not well understood. This paper aims to understand the mechanism, and further show the possibility to utilize the phenomenon as a human interface.
