Mobiles becomes ubiquitous Mobility, flexibility, responsiveness getting

more demands

Devices with small sized have somelimitations

Cant make buttons and screens large

without losing benefit of small sized

Bio-Acoustics: Study Of Sound waves inside living body

When a finger taps the skin, distinct forms of

acoustics energy are produced-Longitudinal waves

Transverse waves

Transverse Wave Propagation Longitudinal Wave PropagationFinger Impacts createstransverse waves(ripples)

Sensor is Activated aswave passes underneath it

Finger impact creates longitudinal(compressive)waves

Causes internal skeletal structureto vibrate

Vibrations are Capturedfrom Sensors and Converted

to Digital signal form

This is connected toMobile device Via Bluetooth

A Software to match sound

frequencies to Specific skinlocation is used

No need to interact with the gadget directly. Dont have to worry about keypad.

People with larger fingers get trouble innavigating tiny buttons and keyboards onmobile phones.

With Skinput that problem disappears.

Can be used without visual screen

We have presented the approach toappropriating the human body as an inputsurface.

We described a novel wearable bio acousticarray used to detect and localize finger tapson the hand and forearm.
