CONTENT
• Overview of SKINPUT
• Need of SKINPUT
• Working Model of SKINPUT
• What actually SKINPUT does
• What are BIO-ACOUSTICS?
• Bio-acoustic SENSING
• ACCURACY of Working
• Advantage
• Disadvantage
• Conclusion
Overview: What is skinput?• Skinput is a joint
collaboration between: Chris Harrison Dan Morris Desney Tan
• Touch-screen gadgets h become popular due to advantages they come with
• Skinput turns the body into a touch-screen interface
Need for Skinput?Motivation• To limit the interaction
space
• We cannot simply make buttons and screens large without losing the primary benefits of small size
Working Model of Skinput…
What skinput does?• Skinput allow simple
tapping for: Playing game Video & control audio
device Making Calls ,
navigation & browsing
• Sensors find the location of tap
• Each part of body creates different types of variations depending on the features of bones, muscle and tension
How Skinput works?Pico – Projector• A very small projector , basically used in gadgets• Eg . Spice popcorn (mobile cum projector)
What are Bio – Acoustics?• Study of sound wave
inside living body
• When a finger taps the skin , several distinct forms of acoustic energy are produced
Longitudinal wavesTransverse waves
• Whole concept is based on wave theory
Bio-Acoustics : Sensing• These signals travels through our muscles and bones and
need to be sensed and worked upon
• This is done by wearing a wave sensor armband on our biceps
Accuracy• Its accuracy of input is:• Five fingers (87.7%)• Whole Arm (95.5%)• Fore arm (81.5%)• Finger Tips (89.6%)• Finger Flicks (96.8%)
Advantages• Larger projected interface
• Distance can be reduced or as required
• Setting can be made for better display in day and night both
• Blind people can also use
Disadvantages• Accuracy degrade with time
• Obsessed body decrease its accuracy
• Armband may slip on wearing too long
• Not affordable for common people
Conclusion• Working is still not crystal clear
• factors like performance, price ,compatibility etc need second thought
• Technology applications vast and need to investigate yet
• Reported that it will not be used for commercial purpose yet
• Microsoft commitment is still a big question
• But still it will bring a Promising and revolutionary change in technology
THANK YOU !!!
