WHAT IS SKINPUT?? Skinput is an input technology that uses bio-

acoustic sensing to localize finger taps on the skin. When augmented with a pico-projector, the device can provide a direct manipulation, graphical user interface on the body.

Developed by Chris Harrison, Desney Tan, and Dan Morris, atMicrosoft Research's Computational User Experiences Group.

Touch screen gadgets have become popular due to the advantages they come with.Skinput turns the body into a touch-screen interface.

TOUCHSCREEN VS. SKINPUT

Touchscreen gadgets have become popular due to the advantages they come with.This a recent innovation called skinput, turns the body into a touchscreen interface.

An armband projects a user interface onto the skin, enabling users to control devices with a larger touchscreen than is offered by many mobile devices

A new skin-based interface called Skinput allows users to use their own hands and arms as touchscreens by detecting the various ultralow-frequency sounds produced when tapping different parts of the skin.

Touch Screen

Motivation Of SkinputThe motivation for the Skinput device is as follows: the performance and usability of mobile devices can be hindered by the size of the input controls on the devices.The authors’ solution to this problem is to use various regions of the user’s skin as an input device.
