Skinput is an input technology that uses bio-acoustic sensing to localize finger taps on the skin.Here is a brief introduction about skinput technology.
3. WHAT IT IS?
A novel input technique that
allows the skin to be used as a
finger input surface.
It is a sensor system
Developed by chris harrison,
Microsoft research.
5. Step :1
When user tap on skin(Hand),
the Bio-acoustics & sensors
study the sound waves.
When a finger taps the skin,
several distinct forms of
acoustic energy are produced
1.Longitudinal wave
2.Tranverse wave
(a)Longitudinal wave
(b) Transverse wave
9. ADVANTAGES
Don’t have to worry about keypad.
No need to interact with the gadgets directly.
People with large fingers get trouble in navigating tiny
buttons and keypads on mobile phones. With skinput
this problem disappears.
12. SKINPUT FUTURE
Extensive research is going on currently on skinput to
1. Make the armband more
smaller.
2. Extend accuracy level.
3. Incorporate more device
with this system.
13. CONCLUSION
Skinput allows the human body as an input surface.
It describes a novel, wearable bio-acoustic sensing
array that we built into an armband in order to detect
and localize finger taps on the forearm and hand.
The system performs well even when the body is in
motion.
