4.  It turns the body into Touch Screen
Interface.
 Developed By Chris Harrison, Desney Tan
And Dan Morris of the Microsoft Research’s
Computational User Experiences Group.
 It is a Technology That Appropriates The
Human Body For Acoustic Transmission.

Required) 7SKINPUT TECHNOLOGY

8.  Allows User To Tap Their skin To Control
Audio Device, Make Call , Play Game
And For Navigation Purposes.
 Uses Series Of Sensors To Determine
Tapped Location.
 Detects Waves Produced Due To Finger
Tap To Perform Action

9.  Each Part Of The Body Creates Different
Types Of Variation Depending On The
Features Of Bones And Muscles.
 Skinput Listens To These Variations To
Determine Tapped Location.

11.  A very small projector basically used in
gadgets.
 E.g. Spice Popcorn (Mobile cum Projector)

12.  Study Of Sound Waves Inside Human Body.
 When Finger Taps Following Waves Are
Produced
A. Longitudinal Waves
B. Transverse Waves
 These Waves Serves Input For The System .

14. These signals need to be
sensed and worked upon
This is done by wearing
the wave sensor Armband
14SKINPUT TECHNOLOGY

15. An audio interface is
captured from
sensors and is
converted to digital
signal form
This is connected
to a pc system via
Bluetooth
A software to match
sound frequencies to
specific skin location
is used.

16.  Fingers (5 Locations)
Whole Arm(5
Locations)
Forearm (10 Location)
 To Maximize the Surface
Area For Input , We Placed
The Sensor Above The
Elbow Leaving the Forearm
Free.

18. Mobile
Gaming
I-pods
Simpler Browsing Systems.
An aid to paralyzed people

19.  No Need To interact with the Gadget
directly .
 Skinput Will Bring a New Way Of
Operating a Mobile Phone By Turning a
Persons Hand Into a Keyboard And Forearm
Into a Screen
 People With Larger Finger Get Trouble in
Navigating Tiny Buttons On Mobile Phones .
With Skinput That Problem Disappears. 19

20. 20SKINPUT TECHNOLOGY
 Accuracy Can Degrade Over Time The
Longer You Wear It.
 Technology Might Start Up At Very
High Cost Which Can Not Be Affordable
For The Common Man.

21. 21SKINPUT TECHNOLOGY
Research is Carried For smaller Wrist Watch
Sized Sensor Armband

SKINPUT TECHNOLOGY
 System Perform Very Well For a Series Of
Gestures Even If The Body Is In Motion.
This Approach Provides An Always Available,
Naturally Portable And On Body Finger Input
System.
Skinput Is Very Interesting Technology But
Its Fate Will Ultimately Depend On How
Committed Microsoft Is To Make It A
Commercial Reality And How Soon.
