One of the pervasive challenges in mobile interaction is decreasing the visual demand of
interfaces towards eyes-free interaction. In this paper, we focus on the unique affordances of
the human ear to support one-handed and eyes-free mobile interaction. We present EarPut,
a novel interface concept and hardware prototype, which unobtrusively augments a variety
of accessories that are worn behind the ear (eg headsets or glasses) to instrument the
human ear as an interactive surface. The contribution of this paper is three-fold. We …
