Skinput Technology

  1. 1. SKINPUT TECHNOLOGY PRESENTED BY : MEDHA CHAUDHURI Bio Medical Engineering Netaji Subhash Engineering College
  2. 2.  Skinput is a technology that appropriates the human body for acoustic transmission, allowing the skin to be used as an input surface.  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. INTRODUCTION
  3. 3. 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.
  4. 4. 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
  5. 5. BIO-ACOUSTICS : SENSING  These signals need to be sensed and worked upon.  This is done by wearing the wave sensor arm band.
  6. 6. WORKING OF SKINPUT TECHNOLOGY
  7. 7. 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.
  8. 8. 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.
  9. 9. THANK YOU
