Overview : Skinput OverviewSkinput is a Bio-acoustic Sensing Technique that allows the body tobe used as an Input Surface.
Overview : Skinput Continued Finger Taps on Skin Creates Several Forms of Acoustic Energy
Overview : Skinput Continued Transverse Wave Propagation: Finger Impacts Displace The Skin Creating Transverse Waves
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.
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.
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.
Overview : Skinput ContinuedRecognizing Input Locations Finalizing Input PointsDesigned Software Listens for impacts & Classifies them. ThenDifferent Interactive Capabilities are bounded on differentregions.
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%()
User Research: SkinputUsing a Pico Projector On the Armband Skinput can also be used as anOutput Surface Using A mobile Phone by Skinput
User Research: SkinputProjection of a Dynamic Finger Inputs are Classified &Graphical Interface processed in Real Time
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.
