3. INTRODUCTION
 Skinput is a technology which uses the surface of the
skin as an input device.
 To capture this acoustic information , they developed
a wearable armband that is non-invasive and easily
removable.
 It was developed by Chris Harrison, Densely Tan, and
Dan Morris of the Microsoft Research's Computational
User Experiences Group(MRCUEG)
.

4.  Skinput 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

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 to 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:
 the ability to detect the ultra low frequency sound
the ‘Pico’ projectors
.
Pico projector applies the use of projector in a
hand held device.
An acoustic detector detects the ultra low
frequency.

7. HOW MAKE IT WORKS

8. 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

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

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

12. HOW IT WORKS
 In Skinput, a keyboard, menu, or other graphics
are beamed onto a user's palm and forearm from
a pico projector embedded in an armband.
 An acoustic detector in the armband then
determines which part of the display is activated
by the user's touch.
 Their software matches sound frequencies to
specific skin locations, allowing the system to
determine which “skin button” the user pressed.

13. PROCESSING: Model

15. IMPLEMENTATION
IMPLEMENTATION ON PARALYZED
PERSON OR PHYSICALLY DISABLE
PERSON.
 If a person is paralyzed or physically
disable we can implement this technology.
The feature of skinput 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
etc.

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

17. USING FINGERS AS CONTROL
PAD OF GAME
 Through Skinput we can play games with just the
movement of our hands. This will introduce a
totally new era of gaming.

18. Making a Phone Call Using
Skinput
 We can turn our arm into a cellphone It will be
possible to make calls by just typing numbers
that flash on your
 forearm[6]. All other functions can also be
performed using Skinput. 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.

19. Controlling Music Player
Applications Using Skinput

20. APPLICATIONS
 Mobile
 Gaming
 I-pods

21. 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
skinput this problem disappears.

22. 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.

23.  The most profound achievement of Skinput is
proving that the human body can be used as a
sensor.
 A person might walk toward their home, tap their
palm to unlock the door and then tap some virtual
buttons on their arms to turn on the TV and start
flipping through channels.
 Extensive Research is going on Currently on
Skinput to
make the armband more smaller.
Incorporate More Devices with This System.
Extend accuracy level.

24. 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.
