Skinput is an input technology that uses bio-acoustic sensing to localize finger taps on the skin. ... While other systems, like SixthSense have attempted this with computer vision, Skinput employs acoustics, which take advantage of the human body's natural sound conductive properties (e.g., bone conduction).

3. ⧭ Screens Are Small,Cameras are more
ubiquitous,touch Screen is everywhere.
⧭ Mobility,Flexibility,Responsiveness are
getting more demands.
⧭ MicroSoft puts Forward a new flesh Control
input technology called Skinput.

4. ⧭ Giving Input Through Skin.
⧭ It listens the vibrations in our body.
⧭ Skinput uses a series of sensors to track
where a user taps on his arm.
⧭ provides an always available mobile input
system.
⧭ Turn the body into touch screen interface.

5. Skinput Vs Touch- Screens

6. Skinput can allow users to simply tap their skin in order
to control audio devices,play games,make phone
calls,and navigate hierarchical browsing systems.
It applies the use of series of sensors to determine
where the user taps on their arms.
Each part of the body creates different types of
variations depending on the features of the
bones,muscle and tendons.

7. Its need Bluetooth
Connection.
A microchip-sized
Pico-Projector.
A acoustic
detector to detect
sound vibrations.

8. Pico-Projector
Small size Projector.
Used for display purpose in skinput system.
Eg. Spice Popcorn(mobile cum projector)
The system comprises three main parts
The Laser Light Source.
The Combiner Optics.
The Scanning mirror.

9. Study of Sound Waves Inside living body.
When a finger tape on skin,several distinct
forms of acoustic energy are produced.
Longitudinal Waves.
Transverse Waves.

11. These Signals need to be sensed and
worked upon.
This is done by wearing
the wave sensor arm
band.

Locations is used. Corresponding

15. Mobile
Gaming
i-Pods
Simpler browsing systems.
An aid to paralyzed people.

16. 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.
easy to access when your phone is not available

17. Accuracy can degrade.
High cost.
Band seems easy enough to slip on.
The easy accessibility will cause people to be more
socially distracted.

18. The most profound achievement of skinput is
proving that the human body can be used as
sensor.
Extend accuracy level.
Incorporate more devices with this system.

19. 1. Skinput’s are not available yet, but could
be in the next few years.
2. This system perform very well even if the
body in motion.
3. In the future your hand could be your i-
phone & your handset could be watch
sized on your wrist.
