ABSTRACT
Devices with small sized have some limitations.
Since can’t make buttons and screens larger without loosing benefit of small sized.
The main reason for appropriating the Human body as an input device are:
Easily accessible by hands.
Introduction
Skinput allows the user to simply tap their skin in order to control audio devices, play games, make phone calls.
It uses the sensors to determine where the user taps on their skin.
What is Skinput
Giving input through skin.
Was developed by Chris Harrison(Mellon Univ.)
Skinput turns the body into a touch screen surface.
Principle of Skinput
It listens to vibrations in your body.
Skinput also responds to the various hand gestures.
The arm is an instrument.
Technology Used
Skinput, the system is a combination of two technologies: the ability to detect the ultra low frequency sound and the Pico- projectors.
Pico projector applies the use of projector in a hand held device.
An acoustic detector detects the ultra low frequency.
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.
Conclusion
I have presented the approach to appropriating the human body as an input interface.
I described a wearable bio-acoustic array used to detect and localize finger tap on the hand and the forearm.
This system performs well even when the body is in motion.
