2. SKINPUT TECHNOLOGY Turns human body into a touch screen
input interface.
3. What is Skinput Technology? Giving input through skin It
listen to vibrations in our body Skin put uses a series of sensors
to track where a user taps on his arm. Provide an always available
mobile input system Turns The body into a touch-screen interface.
The arm is an instrument
4. Screens are smaller, 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. Why this?
5. Introduction Developed by Chris Harrison, Desney Tan, And
Dan Morris of the Microsoft Researchs. First introduced in
Microsofts Techfest 2010. Technology that appropriates the Human
Body as Transmission. Project is Under Active Development, Yet Not
Available Commercially.
6. WHAT SKINPUT DOES ? Allows User to Tap their Skin. Uses
Series of Sensor to determine Tap location. Detect Waves. Body
Creates different types of variations Depending on the features of
Bones and Muscles. Skinput listens to these Variation to determine
Tapped location.
7. WHAT MAKES IT WORKS ? Pico projector Bluetooth Bio
Acoustic
8. HOW SKINPUT WORKS ? Pico Projector : Small Size Projector
Used for display purpose in skinput system.
9. Working When User tap on skin(Hand),the Bio-Acoustics &
Sensors study the sound waves. Variations in bone density, size and
mass and the soft tissue and joints create Acoustically different
locations When a finger taps the skin ,several distinct forms of
acoustic energy are produced Transverse wave. Longitudinal
wave.
10. o When you tap your skin with your finger you generate
transverse waves. o Tapping on soft regions of the arm create
higher amplitude transverse wave than tapping on boney areas.
11. Cause internal skeletal structure to vibrate. These waves
travel through the soft tissues of the arm. Joints play an
important role in making tapped locations acoustically distinct.
This makes joints behave as acoustic filters.
12. Bio - Acoustics : sensing Signal is sensed and worked upon
This is done by wearing sensor armband The two sensor packages
shown Each contain five, specially weighted, cantilevered piezo
films, responsive to a particular frequency range.
13. Armband Prototype Two arrays of five sensing elements
incorporated into an armband Two sensor packages focus on the arm
of input One package was located near the Radius other near the
Ulna Signals transmitted though denser bones
14. Processing
15. Input Location Place the Sensor above the Elbow.
16. Applications Mobile Gaming I-pods Simpler Browsing
Systems.
17. Advantages No Need to Interact with the Gadgets directly. A
new way of operating a mobile phone. People with larger fingers get
trouble in Navigating tiny buttons on Mobile Phones. With Skinput
that problems disappear.
18. Disadvantages Accuracy can degrade. High cost. Band seems
easy enough to Slip on.
19. Future Implications With Small sized Pico Projectors,
skinput oriented systems are an Emerging trend. Research is carried
out for Smaller Wrist Watch sized sensor armband.
20. Conclusion System performs very well for a series of
Gestures even if the body is in motion. This Approach provides an
always available, Naturally portable and on body finger input
system. Skinput is very interesting technology.
