Skinput

  1. 1. Name: Shashaank MathurRoll No.: 113Batch: B-2
  2. 2.  Skinput: Overview Touchscreen and skinput devices Need of skinput Functioning of skinput Working of Skinput Bio-Acoustics Processing Armband Software Specifications Other technologies
  3. 3.  Skinput is a collaboration between Chris Harrison at Cambridge Mellon university and Dan Morris at Microsoft’s research lab Touch screen gadgets have become popular due to the advantage they come with Skinput turns body into touch screen interface
  4. 4.  Device with touch available. Certain drawbacks of these devices present. Some drawbacks are:  Small contact area  Less accurate interactions Cannot make button larger without using primary benefit of small size.
  5. 5.  Primary functions are:  Control audio devices  Play games  Make phone calls  Navigate browsing systems Uses series of sensors to determine where user tapped on skin
  6. 6.  Pico-Projector  A very small projector  Used in compact gadgets  E.g.. Spice Popcorn (mobile cum projector)
  7. 7.  Bio-Acoustics:  Study of sound waves inside body  When finger taps the skin, several distinct forms of acoustics energy are produced  Longitudinal Waves  Transverse Wave  The waveforms form the integral part of skinput
  8. 8.  Finger touch displaces skin Creates transverse wave (ripple) Sensor activated as wave passes under it.
  9. 9.  Finger impacts Creates longitudinal waves (compressive) Causes internal skeletal structure to vibrate.
  10. 10.  Each body part creates different type of vibrations depending on:  Bones  Muscles  Tendons These signal need to be sensed and worked upon. This is done by wearing wave sensor armbands Sensing elements detect vibrations transmitted through the body.
  11. 11.  Sensing elements detect vibrations transmitted through the body. Contain five, specially weighted piezo films Responsive to a particular frequency range.
  12. 12.  Primary application, written in Java Three key functions  Provides a live visualization of the data  It segments inputs from the data stream into independent instances (taps).  Classified these input instances.
  13. 13.  Speech input Wearable computing  Glove based input systems Smart fabric Sixth Sense
  14. 14.  Bulky armband cannot be carried everywhere. Research needs to be done to integrate it in more devices
  15. 15.  Single handed gestures Taps with different parts of the finger Differentiating between materials and objects. Reduction in size of armband.
  16. 16.  Skin as input Wearable bio-acoustic sensors Skinput V/S Other technologies Improvements for skinput
