What Is Skinput Technology??????

Introduction

Skinput is named because it uses the human skin

Skinput, is a sensor system .

Skinput allows the user to simply tap their skin in order to

control audio devices, play games, make phone calls.

Developed by Chris Harrison(Mellon university),

Microsoft research

What is skinput Skinput turns the body into a touch screen surface.

Skinput is an “input technology” mainly used to control mobile devices.

Skinput uses a series of sensors to track where a user taps on his arm.

It listen to vibrations in our body

The arm is an instrument

Components of The Technology

A microchip-sized Pico projector Pico projector applies the use of projector in a

hand held device.

An acoustic detector to detect sound vibrations It detects the ultra low frequency.

It needs Bluetooth connection

Pico Projector

It is also known as pocket projector or mobile projector.

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. Longitudinal Waves Transverse Waves

Longitudinal Waves:

These waves travel through the rigid tissues of the arm, exciting the waves, which can respond to the mechanical vibrations by tapping on a rigid body.

Transverse Waves:

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.

Two sensor packages focus on the arm of input.

Signals transmitted though denser bones.

ADVANTAGES

No need to interact with the gadget directly.

Don’t have to worry about keypad.

Skinput could also be used without a visual interface.

People with larger fingers get trouble in navigating tiny buttons and keyboards on mobile phones. With Skinput that problem disappears.

DISADVANTAGEIndividuals with visible disabilities cannot use this product.

The arm band 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.

APPLICATION

Using skinput, someone could send text messages by tapping his or her arm in certain places .

While walking and jogging, we can listen to music.

Mobile

Gaming

FUTURE SKINPUT

Research is going on to-

Make armband smaller

Incorporate more devices

Extend accuracy level

CONCLUSIONS

This system performs very well even if the body is in motion

in the future your hand could be your iPhone and your handset could be watch-sized on your wrist.
