2.  Skinput is a technology that appropriates the
human body for acoustic transmission, allowing
the skin to be used as an input surface.
 Skinput allows the user to simply tap their skin
in order to control audio devices, play games,
make phone calls.
 It uses the sensors to determine where the user
taps on their skin.
INTRODUCTION

3. TECHNOLOGY USED
 Skinput, the system is a combination of two
technologies: the ability to detect the ultra
low frequency sound and the ‘pico’
projectors.
 Pico projector applies the use of projector
in a hand held device.
 An acoustic detector detects the ultra low
frequency.

4. BIO-ACOUSTICS
 Study of sound waves inside living body.
 When a finger taps the skin, several
distinct forms of acoustic energy are
produced.
 Longitudinal Waves
 Transverse Waves

5. BIO-ACOUSTICS : SENSING
 These signals need to be sensed and
worked upon.
 This is done by wearing the wave
sensor arm band.

6. WORKING OF SKINPUT
TECHNOLOGY

8. ADVANTAGES
 No need to interact with the
gadget directly.
 Don’t have to worry about keypad.
 People with larger fingers get
trouble in navigating tiny buttons
and keypads on mobile phones. With
skinput this problem disappears.

9. CONCLUSION
 This approach is to appropriate
the human body as an input
interface.
 It described a wearable bio-
acoustic array used to detect and
localize finger tap on the hand
and the forearm.
 This system performs well even
when the body is in motion.
