The
widespread adoption of mobile electronic devices and the advent of wearable computing
have encouraged the development of compact alternatives to the keyboard and
mouse. This makes the emerging technology called Skinput a relevant one. Skinput is a technology that appropriates the human body for
acoustic transmission, allowing the skin to be used as an input surface. 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. The skinput technology turns the human hand in to a
virtual key board.
Skinput is a novel technique for physical
communication or interaction, which is focused on mobile devices that utilize
‘skin’ as an info interface. This info interfacing method is an integration of
some bio-acoustic sensors and machine learning languages, which helps people,
to utilize their fingers, arms or any other part of their bodies as a track pad
or touch pad to operate and control various devices. Skinput combines simple bio-acoustic sensors and some
sophisticated machine learning to enable people to use their fingers or
forearms as touch pads. Different types of finger taps on different parts of
the hand and forearm produce unique acoustic signatures. A simple input device
used here provides an acoustic signal, which the system decomposes into various
unique features. Machine interpretation parses this features into a unique identification of the different taps. Skinput gives new
meaning to the term “touch typing.”
