ABSTRACT
We present Skinput, a technology that appropriates the human body for acoustic transmission, allowing the skin to be
used as an input surface.
In particular, we resolve the location of finger taps on the arm and hand by analyzing mechanical vibrations that propagate through the body.
We
collect these signals using a novel array of sensors worn as
an armband.
This approach provides an always available,
naturally portable, and on-body finger input system.
We
assess the capabilities, accuracy and limitations of our technique through a two-part, twenty-participant user study.
To
further illustrate the utility of our approach, we conclude
with several proof-of-co
