Hanger Reflex : A Head Rotational Movement Induced by a Compression to the Head : Condition Identification and Reproduction of the Phenomenon

Abstract

When a head is equipped with a hanger made of wire sideways, and its temporal region is sandwiched by the hanger, the head rotates unexpectedly. We named the phenomenon "Hanger Reflex", and we have studied this phenomenon to understand its mechanism and to show the possibility of utilizing the phenomenon as a human interface or for rehabilitation. In this paper, we evaluated that the necessary conditions of the Hanger Reflex are compressions to temporofromtal region of the head and its counter position. We also developed an interface that can induce head rotation by Hanger Reflex, without giving pain to the user.
