Overview
Skinput is a Bio-acoustic Sensing Technique that allows the body to be used as an Input Surface.
Overview : Skinput
Finger Taps on Skin Creates Several Forms of Acoustic Energy
Overview : Skinput Continued
Overview : Skinput Continued
Transverse Wave Propagation: Finger Impacts Displace The Skin Creating Transverse Waves
Overview : Skinput Continued
Longitudinal Wave Propagation: Finger Impacts Create longitudinal(Compressive) waves that cause internal structures to vibrate. This in turn Creates longitudinal Wave Forms outwards from the bone towards skin.
Overview : Skinput ContinuedOutside View Inside View
A Wearable Bio-acoustic Sensing Array Built into an Armband. Sensing Elements detect vibrations transmitted through the body. The two sensor packages shown above each contain five specially weighted cantilevered 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 Points
Designed Software Listens for impacts & Classifies them. Then Different Interactive Capabilities are bounded on different regions.
User Research: Skinput
Playing Tetris: Using Fingersas Control Pad
Active also in Movable Environment
Using Fingers,Palms,Arms as Control Any Computing Device Can be run.Response is real time,robust & remains functional while walking & Accuracy level is 99.5%()
User Research: SkinputUsing a Pico Projector On the Armband Skinput can also be used as an Output Surface
Using A mobile Phone by Skinput
User Research: SkinputProjection of a Dynamic Graphical Interface
Finger Inputs are Classified & 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.
