Skinput

  1. 1. THE HUMAN BODY AS TOUCH SCREEN
  2. 2. Introduction 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.
  3. 3. What is Skinput Skinput turns the body into a touch screen surface. Skinput is an “input technology” mainly used to control mobile devices. Skinput is named because it uses the human skin as an input devices or tracking surface.
  4. 4. Principle of Skinput It listens to vibrations in your body. Skinput also responds to the various hand gestures. The arm is an instrument.
  5. 5. Technology Used Skinput, the system is a combination of two technologies: the ability to detect the ultra low frequency sound and the ‘pico’ projectors. Pico projector applies the use of projector in a hand held device. An acoustic detector detects the ultra low frequency.
  6. 6. Pico Projector It is also known as pocket projector or mobile projector. The system comprises three main parts: The Laser light source The Combiner optics The Scanning mirror
  7. 7. Bio-Acoustics Study of sound waves inside living body. When a finger taps the skin, several distinct forms of acoustic energy are produced. Longitudinal Waves Transverse Waves
  8. 8. Longitudinal Waves:These waves travel through the rigidtissues of the arm, exciting the waves,which can respond to the mechanicalvibrations by tapping on a rigid body. TransverseWaves:Tapping on soft regions of the armcreates higher amplitude transversewaves.
  9. 9. Bio-Acoustics: Sensing These signals need to be sensed and worked upon. This is done by wearing the wave sensor arm band.
  10. 10. Percent Accuracy
  11. 11. Advantages 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.
  12. 12. Applications Mobile Gaming I-pods An aid to paralyzed persons.
  13. 13. Future Implications With small sized Pico-projectors, Skinput oriented systems, are an emerging trend. Research is carried out for smaller wrist watch sized sensor arm band.
  14. 14. Conclusion This approach is to appropriate the human body as an input interface. It described a wearable bio-acoustic array used to detect and localize finger tap on the hand and the forearm. This system performs well even when the body is in motion.
  15. 15. THANKYOU
  16. 16. QUERIES
