3. 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
4. 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
6. 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
7. How Skinput works?
Pico – Projector
• A very small projector , basically used in gadgets
• Eg . Spice popcorn (mobile cum projector)
8. 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 waves
Transverse waves
• Whole concept is based on
wave theory
9. 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
10. 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%)
11. 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
12. Disadvantages
• Accuracy degrade with time
• Obsessed body decrease its accuracy
• Armband may slip on wearing too long
• Not affordable for common people
13. 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
