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.
