  • 1. Presented ByAbhijeet S. Kapse Guided ByProf. S.B. Somani MITCOE
  • 2.  Introduction What is Skinput Principle of Skinput How it works Advantages Applications Future Implementation Conclusion MITCOE
  • 3.  Mobiles becomes ubiquitous Mobility, flexibility, responsiveness getting more demands Devices with small sized have some limitations Can’t make buttons and screens large without losing benefit of small sized Microsoft introduces new flesh-control input technology-”Skinput” MITCOE
  • 4.  Collaboration between Chris Harrison at Carnegie Mellon University and team of Microsoft research lab. Touch-Screen gadgets have become popular due to the advantages they come with Skinput turns the body into a touch-screen interface MITCOE
  • 5.  Skinput allow the users to simply tap their skin in order to control mobile applications It applies the use of series of sensors to determine where user taps on their arms Each part of body creates different types of vibrations depending on features of bones, muscle and tendons MITCOE
  • 6. Bio- AcousticsBluetooth Pico- Projector MITCOE
  • 7. Pico-Projector: Small Sized Projector to Display menu Widely Used in Gadgets like Mobile , Camera MITCOE
  • 8. Bio-Acoustics: Study Of Sound waves inside living body When a finger taps the skin, distinct forms of acoustics energy are produced- Longitudinal waves Transverse waves MITCOE
  • 9. Transverse Wave Propagation Longitudinal Wave Propagation • Finger Impacts creates • Finger impact creates longitudinal transverse waves(ripples) (compressive)waves • Sensor is Activated as • Causes internal skeletal structure wave passes underneath it to vibrate MITCOE
  • 10. • Wave Sensor Armband• Responsive to the Vibrations MITCOE
  • 11. Processing : Model Vibrations are Capturedfrom Sensors and Converted to Digital signal form This is connected to Mobile device Via Bluetooth A Software to match sound frequencies to Specific skin location is used Corresponding Action is implemented in Device MITCOE
  • 12. Fingers•Tapping on tips of fingers• Accurately Interact with eyes free mannerArm• Maximum Surface area• Provides 10 Different Locations MITCOE
  • 13. Ten Channels of acoustic data generated by three finger taps on the Forearm, followed by three taps on Wrist MITCOE
  • 14. MITCOE
  • 15.  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 keyboards on mobile phones. With Skinput that problem disappears. Can be used without visual screen MITCOE
  • 16.  Mobile i-Pods Gaming Simpler Browsing System MITCOE
  • 17.  Small Sized Pico-projector Wrist watch size sensor armband MITCOE
  • 18.  We have presented the approach to appropriating the human body as an input surface. We described a novel wearable bio acoustic array used to detect and localize finger taps on the hand and forearm. MITCOE
