2. Introduction to SKINPUT
2
 Skinput turns our
body into touch
screen interface.
 Thus we can use
our own skin as
input canvas.
 This technology
uses the screen as
the tracking
surface or the
unique input
device

3. What is Skinput
3
 Giving input through
skin.
 It was developed by
Chris Harrison (
Carnegie Mellon
University),
Microsoft Research.
 Skinput turns skin
into a touch screen
interface.

4. Touch Screen vs. Skinput Technology
4
 A touch screen is an electronic
visual display that can detect
the presence and location of a
touch within the display area.
 Needs visual assistance.
• Turns our skin into touch screen.
• Visual assistance is not needed.

5. Principle of Skinput
5
 It listens to the
vibrations in the
body.
 Skinput also
responds to various
hand gestures.
 The arm itself is an
instrument.

6. How it works
6
• It needs Bluetooth connection.
• It uses a microchip-sized Pico projector to
display menu.
• An acoustic detector to detect sound
vibrations.

8. Waves Generated
8
FIG: Transverse wave propagation: Finger impacts displace the skin, creating transverse
waves (ripples). The sensor is activated as the wave passes underneath it.
FIG: Longitudinal wave propagation: Finger impacts create longitudinal (compressive) waves
that cause internal skeletal structures to vibrate. This, in turn, creates longitudinal waves that
emanate outwards from the bone (along its entire length) toward the skin.

10. Advantages
10
 No need to interact with the gadget directly.
 No need to worry about keypad.
 People with larger fingers get trouble in navigating tiny buttons
and keyboards on mobile phones. With Skinput that problem
disappears.
 Skinput will bring in a new way of operating a mobile phone, by
turning a persons hand into a keyboard and forearm into a screen.

11. Applications
11
 I pods
 Gaming
 Mobile
 Simple browser
systems

12. Conclusion
12
 Skinput technology provides an always available mobile input
system that does not require a user to carry or pick up a device.
 Using skinput technology, human body can be appropriated as an
input surface to any of the devices ,system performs very well for
a series of gestures, even when the body is in motion.
