Skinput technology enables users to control audio devices by tapping their skin, utilizing the body's acoustic properties for input. It combines the detection of ultra low frequency sounds with pico projectors to create an innovative interaction method, particularly benefiting those with larger fingers. The system includes a wearable bio-acoustic array that effectively detects finger taps on the body, even during motion.

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.

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.
