5. INTRODUCTION
Skinput is a technology which uses the surface of the skin as an
input device.
To capture this acoustic information, there is an wearable armband
developed that is easily removable and light in weight.
Skinput allows the user to simply tap their skin in order to control
various devices.
It uses the sensors to determine where the user taps om their skin.

6. WHAT IS SKINPUT. . .???
• Skinput is a combo of two technology i.e. the ability to detect the ultra low frequency sound and
the pico projector.
• Turns The body into a TOUCH-SCREEN
interface.
• Giving input through skin.
• Skinput uses a series of sensors to track where a user taps on his arm.
• It listen to vibration in our body.
• Provides an always available mobile input
system.
• Basically the arm is an instrument.

7. REQUIREMENTS:
•An acoustic detector to detect sound vibrations.
•It uses a microchip-sized pico projector to display menu.
•It needs Bluetooth connection.

8. HARDWARE REQUIREMENTS
PROTOTYPE
ARMBAND
.

9. HOW IT WORKS….???
In skinput, a keyboard, menu and other graphics are beamed onto a
user’s palm and forearm from a pico projector embedded in an arm
band.
 an acoustic detector in the arm band can determine 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 “skin button” the user
pressed.

10. BASIC PRINCIPLE

11. .
 To maximize the surface area for
input, we place the sensor above
the elbow, leaving the entire
forearm free.
 This increases input consistency.
 Accuracy does drop when 10 or more locations are used.
ACCURACY

12. SURFACE AND OBJECT RECOGNIZATION
• Ability to identify the operating system.
• Participants to tap their index finger against
1. a finger on their other hand
2. a page pad 80 pages thick
3. an LCD screen

13. ADVANTAGES
• No need to interact with the gadgets directly.
• Don’t have to worry about keypad.
• Via skinput we can control audio devices, play games, make phone calls.
• We can even have a control over our TV with the help of remote connection.
• People with larger fingers get trouble in navigating tiny buttons and
keyboards on mobile phones. With skinputs that problem disappears.
• Through the help of skinput technology we can implement in education
system like we can use calculator or browsing through a mobile phone etc…

14. DISADVANTAGES
• Individuals with visual disabilities cannot use this product.
• The armband is currently bulky.
• The visibility of the projection of the buttons on the skin can be reduced if the user has a
tattoo located on their arm.
• The east accessibility will cause people to be more socially distracted.
• The technology might startup at a very high cost which will not be affordable by comman
man.
• Enough resources has not been conducted on skinput to test skin diseases or cancer.

15. APPLICATIONS
• The skinput system can display an image of a digital keyboard on a person’s forearm.
• Using Skinput, someone could send text messages, make a phone call by tapping his or her
arm in certain places.
• While walking and logging, we can listen to music.
• One can play games via skinput just with the tapping on arm.

16. FUTURE SKINPUT
• The achievement of skinput is proving that the human body can be used as a
sensor.
• One can simply tap their palm to unlock the door and can turn ON/OFF TV
and start flipping through channels.
Research is going on to-
 Make armband smaller.
Incorporate more devices.
Extend accuracy level.

17. CONCLUSION
• Skinput allows the human body as an input surface.
• It descrives a wearable bio acoustic sensing array that we built
into an arm in order to detect and localize finger tap on forearm
and hands.
• This system performs well even when the body is in motion.
