6. • Skinput is a technology that appropriates the human body
for acoustic transmission.
• It allows the skin to be used as an input surface.
• It was developed by Chris Harrison, Densely Tan, and Dan
Morris of the Microsoft Research's Computational User
Experiences Group(MRCUEG)
• Its first public appearance was at Microsoft's Tech Fest 2010
• 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.

7.  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 them
to electronic signals which easily enable the users to
perform simple tasks as browsing through a mobile
phone menu, making calls, controlling portable music
players, etc..

8. • Skinput, the system is a combination of two
technologies:
1. the ability to detect the ultra low frequency sound
2. the ‘Pico’ projectors.
 Pico projector applies the use of projector in a hand
held device.
 An acoustic detector detects the ultra low
frequency.

9. • A very small projector, basically used in gadgets.
• The system comprises three main parts:
 The Laser light source
 The Combiner optics
 The Scanning mirror

10. • In Skinput, a keyboard, menu, or other graphics are beamed
onto a user's palm and forearm from a pico projector
embedded in an armband.
• An acoustic detector in the armband then determines which
part of the display is activated by the user's touch.
• Their software matches sound frequencies to specific skin
locations, allowing the system to determine which “skin
button” the user pressed.
• Currently, the acoustic detector can detect five skin locations
with an accuracy of 95.5%, which corresponds to a sufficient
versatility for many mobile applications.
• The prototype system then uses wireless technology like
Bluetooth to transmit the commands to the device being
controlled, such as a phone, iPod, or computer.

13.  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.

14. • Skinput allows the human body as an input
surface.
• It describes a novel, wearable bio-acoustic
sensing array that we built into an armband in
order to detect and localize finger taps on the
forearm and hand.
• We conclude with descriptions of several
prototype applications that demonstrate the
rich design space we believe Skinput enables.

THINK OVER….
