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 the Microsoft Research's Computational User Experiences Group(MRCUEG)

The primary goal of Skinput is to provide an always available mobile input system

.

Skinput allows the user to simply tap their skin in order to control audio devices, play games etc.

It uses the sensors to determine where the user taps on their skin.

Its first public appearance was at Microsoft's Tech Fest 2010

PRINCIPLE OF SKINPUT

It listens to vibrations in your body.Skinput also responds to the various hand gestures.

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..

HOW MAKE IT WORK

PICO- PROJECTORVery small projector, basically used in gadgetsPico projector applies the use of projector in a hand

held device. The system comprises three main parts:

The Laser light source The Combiner optics The Scanning mirror

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 WavesAn acoustic detector detects the ultra low

frequencyThese waves form the integral part of the

whole concept of skinput.

BIO- ACOUSTICS (SENSING)

These signals need to be sensed and worked upon.

This is done by wearing the wave sensor arm band.

HOW IT WORKS

In Skinput, a keyboard, menu, or other graphics are beamed onto a user's arm 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.

PROCESSING: Model

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.

ADVANTAGES

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.

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.

SKINPUT IN FUTURE

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 arm 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.

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.
