3. INTRODUCTION:
 Skin-put is a technology which uses the surface of the skin an
input device.
 Skin-put allows the user to simply tap their skin in order to
control audio devices, play games, make phone call.
 It uses the sensors to determine where the user taps on their
skin.
 Its first public appearance was at Microsoft's Tech Fest 2010.
To capture this acoustic information , they developed a
wearable armband that is easily removable.

4. EVOLUTION OF TECHNOLOGY
 Skin-put Technology was introduced by Microsoft
Corporation at their first public appearance in Microsoft Tech
fest in 2010 where the prototype was shown live on the event.
 Developed by Chris Harrison and Dan Morris at Microsoft
Research, Skin-put utilizes the skin as an input surface,
enabling users to interact with digital devices through taps,
gestures, and touches on their own skin.

5. PRINCIPLE OF SKINPUT
 It listens to vibrations in your body.
 Skinput also responds to the various hand gestures.
 The arm is an instrument.
 Arm band detects the acoustic signals and convert them o
electronic signals which easily enable the users to perform
simple tasks as browsing through a mobile phone menu,
making calls, controlling portable music players, etc,,,

6. Skinput, the system is a combination of two technologies:
1. The ability to detect the ultra low frequency sound and the
‘Pico’ projectors.
2. Pico projector applies the use of projector in a hand held
device.
An acoustic detector detects the ultra low frequency.

7. COMPONENTS REQUIRED
 Microchip-sized Pico-projector
(Used to display menu)
 Bio-acoustic sensing
(Used to detect sound vibrations)
 Bluetooth
(Connection purpose)

8. HOW IT WORKS:

9. PICO- PROJECTOR
A very small projector, basically used in gadgets
The system comprises three main parts:
 The Laser light source
 The Combiner optics
 The Scanning mirror

10. BIO- ACOUSTICS
 Study of sound waves inside living body.
 When a finger taps the skin, several distinct forms of
acoustic energy are produced.
1. Longitudinal Waves
2. Transverse Waves
These waves form the integral part of the whole concept
of skinput.

12. BIO- ACOUSTICS: SENSING
 These signals need to be sensed and worked upon.
 This is done by wearing the wave sensor arm band.

14. IMPLEMENTATION
IMPLEMENTATION IN EDUCATION SYSTEM
Through the help of Skin-put technology we can implement
in education system like we can use calculator or browsing
through a mobile phone etc...

15. Making a Phone Call Using Skin-put
 We can turn our arm into a cellphone It will be possible to
make calls by just typing numbers that flash on your
fore-arm. All other functions can also be performed using
Skin-put. We can also increase or decrease the volume or
change the track of our music players like the i-pod without
actually touching the gadget.

16. Implementation on paralyzed person
or physically disable person
If a person is paralyzed or physically disable we can implement
this technology. The feature of skin-put technology provides a
projected graphical interface on the skin, so the person who is
paralyzed or physically disable they can use it easily like making
a call, playing game, control music player application.

17. APPLICATIONS
 Mobile Computing(used to control smartphones without
needing physical touch screen)
 Fitness and Healthcare(analyzing signals from the body such
as heartrate, blood pressure)
 Industrial and Military
 Authentication and Security
 Gaming
 Education system

18. ADVANTAGES
 No need to interact with the gadget directly.
 Don’t have to worry about keypad.
 People with larger fingers get trouble in navigating tiny
buttons and keypads on mobile phones. With skin-put this
problem disappears.

19. DISADVANTAGES
 Though the band seems easy enough to slip on, many
people would not wear a very big band around their arm for
the day.
 Not enough research has been conducted on this product to
test the possible skin diseases or types of cancer, one can
get from using this product.
 This technology might start up at very high cost which will
not be affordable for the common man.

20. SKINPUT IN FUTURE
 In the future your hand could be your i-phone & your hand
set could be watch sized on your wrist.
 Extend accuracy level.
 Incorporate more devices with this system.
 Extension to research is going on currently on skin-put to
make the armband more smaller.

21. CONCLUSION
 Skinput allows the human body as an input surface.
 It describes a novel, wearable bio-acoustic sensing array
that we built into an armband in order to detect and localize
finger taps on the forearm and hand.
 This system performs well even when the body is in
motion.
