  1. THE HUMAN BODY AS TOUCH SCREEN Presented by:- Suraj Duhan LC08570 EECE-7th sem

  2. CONTENTS • Abstract • Introduction • What is Skinput • Principle of skinput • How it works • Advantages • Applications • Future Implications • Conclusion

  3. ABSTRACT • Devices with small sized have some limitations. • Since can’t make buttons and screens larger without loosing benefit of small sized. • The main reason for appropriating the Human body as an input device are: • Easily accessible by hands.

  4. 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.

  5. What is Skinput • Giving input through skin. • Was developed by Chris Harrison (Mellon Univ.) • Skinput turns the body into a touch screen surface.

  6. Principle of Skinput • It listens to vibrations in your body. • Skinput also responds to the various hand gestures. • The arm is an instrument.

  7. 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.

  8. 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

  9. 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

  10. Longitudinal Waves: These waves travel through the rigid tissues of the arm, exciting the waves, which can respond to the mechanical vibrations by tapping on a rigid body. Transverse Waves:Tapping on soft regions of the arm creates higher amplitude transverse waves.

  11. Bio-Acoustics: Sensing • These signals need to be sensed and worked upon. • This is done by wearing the wave sensor arm band.

  12. Percent Accuracy

  13. 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.

  14. Applications • Mobile • Gaming • I-pods • An aid to paralyzed persons.

  15. 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.

  16. Conclusion • I have presented the approach to appropriating the human body as an input interface. • I 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.
