THE HUMAN BODY AS TOUCH SCREEN

2. INTRODUCTION
 Skinput is a technology which uses the surface of the skin
as an input device
 It was developed by Chris Harrison, Densely Tan, and Dan
Morris of MRCUEG.
 Skinput allows the user to simply tap their skin in order to
control audio devices, play games, make phone call.

3. TOUCH SCREEN V/S SKINPUT

4. PRINCIPLE OF SKINPUT
 It listens to vibrations in your body.
 Skinput also responds to the various hand gestures.
 Skinput, the system is a combination of two technologies
›‘Pico’ which applies the use of projector in a handheld
device
›Acoustic detector detects the ultra low frequency

6. 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

7.  BIO- ACOUSTICS
 Study of sound waves inside living body.
 Longitudinal Waves and Transverse Waves
 These waves excites the bone.
 The sensor is activated as the waves pass underneath it.
 These signals need to be sensed and worked upon.
 This is done by wearing the wave sensor armband.

8. 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.

10. INPUT LOCATIONS
 fingers
 whole arm
 forearm
 to maximize surface we place the sensor above the elbow

11. PERCENT ACCURACY

12. APPLICATIONS
 On paralyzed person or physically disable person
 In education system
 Using fingers as control pad of game
 Making a phone call using skinput

13. 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.

14. DISADVANTAGES
 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 devices.

15. SKINPUT IN FUTURE …
 The most profound achievement of Skinput is proving that
the human body can be used as a sensor.
 Home automation.
 Extensive Research is going on Currently on Skinput

16. CONCLUSION :
 The technology itself is intriguing , and have more
application other than always availability.
 Its fate will ultimately depend on how committed Microsoft
is to making it a commercial reality and how soon.
