3. Introduction
• Skinput turns our body
into touch screen
interface
• This technology uses the
screen as the tracking
surface or the unique
input device
• It was developed by Chris
Harrison, Densely Tan, and
Dan Morris of the
Microsoft Research's
Computational User
Experiences
Group(MRCUEG)
4. PRINCIPLE OF SKINPUT
It listens to the
vibrations in the
body.
Skin put also
responds to
various hand
gestures.
The arm itself is
an instrument.
5. Equipment required
• It needs Bluetooth
connection.
• It uses a microchip-
sized Pico projector
to display menu.
• An acoustic
detector to detect
sound vibrations.
7. Waves Generated
• FIG: Transverse wave propagation: Finger impacts
displace the skin, creating transverse waves (ripples).
The sensor is activated as the wave passes underneath
it.
FIG: Longitudinal wave propagation: Finger impacts create longitudinal
(compressive) waves that cause internal skeletal structures to vibrate. This,
in turn, creates longitudinal waves that emanate outwards from the bone
(along its entire length) toward the skin.
8. BIO- ACOUSTICS: SENSING
These signals need to be sensed and worked upon.
This is done by wearing the wave sensor arm band.
9. HOW IT WORKS
• In Skinput, a keyboard, menu, or other graphics
are beamed onto a user's palm and forearm
from a Pico projector embedded in an armband.
• An acoustic detector in the armband then
determines which part of the display is activated
by the user's touch.
• Their software matches sound frequencies to
specific skin locations, allowing the system to
determine which “skin button” the user pressed.
12. Advantages
No need to interact with the gadget directly.
No need to worry about keypad.
People with larger fingers get trouble in navigating tiny buttons
and keyboards on mobile phones. With skinput that problem
disappears.
Skinput will bring in a new way of operating a mobile phone, by
turning a persons hand into a keyboard and forearm into a screen.
13. IMPLEMENTATION
IMPLEMENTATION ON PARALYZED PERSON OR PHYSICALLY
DISABLE PERSON.
If a person is paralyzed or
physically disable we can
implement this technology. The
feature of skinput technology
provides a projected graphical
interface on the skin, so the person
who is paralyzed or physically
disable they can use it easily like
making a call, playing game,
control music player application
etc.
14. IMPLEMENTATION IN EDUCATION
SYSTEM
Through the help of Skinput
technology we can
implement in education
system like we can use
calculator or browsing
through a mobile phone etc..
15. USING FINGERS AS CONTROL PAD OF
GAME
• Through Skinput we can play games with just
the movement of our hands. This will introduce
a totally new era of gaming.
16. Making a Phone Call Using
Skinput
• We can turn our arm into a
cell phone It will be possible
to make calls by just typing
numbers that flash on your
• forearm[6]. All other
functions can also be
performed using Skinput.
We can also increase or
decrease the volume or
• change the track of our
music players like the i-pod
without actually touching
the gadget.
19. Conclusion
• Skin put allows the human body as an input
surface.
• This system performs well even when the
body is in motion
• Skin put technology provides an always
available mobile input system that does not
require a user to carry or pick up a device.
