THE HUMAN BODY AS TOUCH SCREEN

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.

TOUCH SCREEN V/S SKINPUT

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

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

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.

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.

INPUT LOCATIONS

fingers

whole arm

forearm

to maximize surface we place the sensor above the elbow

PERCENT ACCURACY

APPLICATIONS

On paralyzed person or physically disable person

In education system

Using fingers as control pad of game

Making a phone call using skinput

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.

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.

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

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.
