THE HUMAN ARM AS TOUCH SCREENSKINPUT TECHNOLOGY1

SWATHI. B

Introduction to SKINPUT2

Skinput turns our body into touch screen interface.

Thus we can use our own skin as input canvas.

This technology uses the screen as the tracking surface or the unique input device

What is Skinput3

Giving input through skin.

It was developed by Chris Harrison ( Carnegie Mellon University), Microsoft Research.

Skinput turns skin into a touch screen interface.

Touch Screen vs. Skinput Technology4

A touch screen is an electronic visual display that can detect the presence and location of a touch within the display area.

Needs visual assistance.

• Turns our skin into touch screen.

• Visual assistance is not needed.

Principle of Skinput5

It listens to the vibrations in the body.

Skinput also responds to various hand gestures.

The arm itself is an instrument.

How it works6

• It needs Bluetooth connection.

• It uses a microchip-sized Pico projector to display menu.

• An acoustic detector to detect sound vibrations.

Skin Interface7

The three input location sets evaluated in the study.

Waves Generated8

FIG: Transverse wave propagation: Finger impacts displace the skin, creating transverse

waves (ripples). The sensor is activated as the wave passes underneath it. 

FIG: Longitudinal wave propagation: Finger impacts create longitudinal (compressive) waves that cause internal skeletal structures to vibrate. This, in turn, creates longitudinal waves that

emanate outwards from the bone (along its entire length) toward the skin.

Wearable Arm Band9

Advantages10

No need to interact with the gadget directly.

No need to worry about keypad.

People with larger fingers get trouble in navigating tiny buttons and keyboards on mobile phones. With Skinput that problem disappears.

Skinput will bring in a new way of operating a mobile phone, by turning a persons hand into a keyboard and forearm into a screen.

Applications11

I pods

Gaming

Mobile

Simple browser systems

Conclusion12

Skinput technology provides an always available mobile input system that does not require a user to carry or pick up a device.

Using skinput technology, human body can be appropriated as an input surface to any of the devices ,system performs very well for a series of gestures, even when the body is in motion.
