• Skinput is a technology that appropriates the human bodyfor acoustic transmission.

• It allows the skin to be used as an input surface.

• It was developed by Chris Harrison, Densely Tan, and DanMorris of the Microsoft Research's Computational UserExperiences Group(MRCUEG)

• Its first public appearance was at Microsoft's Tech Fest 2010

• Skinput allows the user to simply tap their skin in order tocontrol audio devices, play games, make phone calls.

• It uses the sensors to determine where the user taps ontheir skin.

It listens to vibrations in your body.

Skinput also responds to the various hand gestures.

The arm is an instrument.

Arm band detects the acoustic signals and convert themto electronic signals which easily enable the users toperform simple tasks as browsing through a mobilephone menu, making calls, controlling portable musicplayers, etc..

• Skinput, the system is a combination of twotechnologies:

1. the ability to detect the ultra low frequency sound

2. the ‘Pico’ projectors.

Pico projector applies the use of projector in a handheld device.

An acoustic detector detects the ultra lowfrequency.

• A very small projector, basically used in gadgets.

• The system comprises three main parts:

The Laser light source The Combiner optics The Scanning mirror

• In Skinput, a keyboard, menu, or other graphics are beamedonto a user's palm and forearm from a pico projectorembedded in an armband.

• An acoustic detector in the armband then determines whichpart of the display is activated by the user's touch.

• Their software matches sound frequencies to specific skinlocations, allowing the system to determine which “skinbutton” the user pressed.

• Currently, the acoustic detector can detect five skin locationswith an accuracy of 95.5%, which corresponds to a sufficientversatility for many mobile applications.

• The prototype system then uses wireless technology likeBluetooth to transmit the commands to the device beingcontrolled, such as a phone, iPod, or computer.

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.

The body is portable and always available, and fingers are a natural

input device.

Though the band seems easy enough to slip on, 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 or types of cancer, one can get from

using this product.

This technology might start up at very high cost which will not be

affordable for the common man.

• Skinput allows the human body as an inputsurface.

• It describes a novel, wearable bio-acousticsensing array that we built into an armband inorder to detect and localize finger taps on theforearm and hand.

• We conclude with descriptions of severalprototype applications that demonstrate therich design space we believe Skinput enables.

ITZ UR TURN TO THINK OVER….
