INTRODUCTIONSkinput 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 easily removable.

It was developed by Chris Harrison, Densely Tan, and Dan Morris of the Microsoft Research's Computational User Experiences Group(MRCUEG)

CONTINUE……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.

PRINCIPLE OF SKINPUTIt 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, 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. It is also known as pocket projector or mobile projector.

The system comprises two main parts: The Laser light source The Scanning mirror

Bio-AcousticsStudy of sound waves inside living body.When a finger taps the skin, several distinct

forms of acoustic energy are produced.Longitudinal WavesTransverse Waves

Longitudinal Waves:These waves travel through the soft tissues of the arm,

which can respond to the mechanical vibrations by tapping on a rigid body. TransverseWaves:Tapping on soft regions of the arm creates higher amplitude transverse waves.

BIO- ACOUSTICS (SENSING)These signals need to be sensed and worked

upon.This is done by wearing the wave sensor

arm band.

BLUETOOTH

Wireless technology for exchanging data over short distances

Bio acoustic sensors are connected to mobile bluetooth

HOW IT WORKSIn 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.

PROCESSING: Model

ADVANTAGESEasy to workNo 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.

The body is portable and always available, and fingers are a natural input device.

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.• very high cost

• Mobile• Gaming• I-pods

APPLICATIONS

SKINPUT IN FUTUREThe 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.

Extend accuracy level.

CONCLUSIONSkinput 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.
