Skinput msu

  1. 1. Invented ByPresented By Md. Shihab Uddin Roll : 0607029 CSE,KUET
  2. 2. Outline• Overview• User Research• Future• References
  3. 3. Overview : Skinput OverviewSkinput is a Bio-acoustic Sensing Technique that allows the body tobe used as an Input Surface.
  4. 4. Overview : Skinput Continued Finger Taps on Skin Creates Several Forms of Acoustic Energy
  5. 5. Overview : Skinput Continued Transverse Wave Propagation: Finger Impacts Displace The Skin Creating Transverse Waves
  6. 6. Overview : Skinput ContinuedLongitudinal Wave Propagation:Finger Impacts Create longitudinal(Compressive) waves thatcause internal structures to vibrate. This in turn Createslongitudinal Wave Forms outwards from the bone towardsskin.
  7. 7. Overview : Skinput ContinuedOutside View Inside ViewA Wearable Bio-acoustic Sensing Array Built into an Armband. SensingElements detect vibrations transmitted through the body. The twosensor packages shown above each contain five specially weightedcantilevered piezo films responsive to a particular frequency range.
  8. 8. Overview : Skinput ContinuedFinger Taps on Arm Generated Signals Variation in Bone Density, Size & Mass as well as filtering effects from Soft Tissues & Joints Mean Different Locations that are acoustically distinct.
  9. 9. Overview : Skinput ContinuedRecognizing Input Locations Finalizing Input PointsDesigned Software Listens for impacts & Classifies them. ThenDifferent Interactive Capabilities are bounded on differentregions.
  10. 10. User Research: SkinputPlaying Tetris: Using Fingers Active also in Movableas Control Pad EnvironmentUsing Fingers,Palms,Arms as Control Any Computing Device Canbe run.Response is real time,robust & remains functional whilewalking & Accuracy level is 99.5%()
  11. 11. User Research: SkinputUsing a Pico Projector On the Armband Skinput can also be used as anOutput Surface Using A mobile Phone by Skinput
  12. 12. User Research: SkinputProjection of a Dynamic Finger Inputs are Classified &Graphical Interface processed in Real Time
  13. 13. Future: Skinput• Extensive Research is going on Currently on Skinput to make the armband more smaller.Incorporate More Devices with This System.Extend accuracy level.
