Introduction A wearable, gestural interface that
augments the physical world around us with thedigital information.
Integrates the digital information into thephysical world and its objects, making the entireworld your computer.
Developed by Pranav Mistry, a PhDstudent in the Fluid Interfaces Group at the MITMedia Lab.

Bridges the gapbetween
the tangible and theintangible world.
It is a technologywhich aims at causingcomputers and othermachines to adapt to
human needs.
The current prototypecosts around $350.

Genesis
The first gesture interface device wascreated by attaching some strings and
pulleys to the rollers of a scroll mouse.

Another exploration wasaimed at helping thedesigners and architects toimagine and draw objects in
3- dimensions.
The device was a pen
that could draw in 3-dimensions.

Human mind is interested indynamic information, rather than
in computing.
The next phase was to go theother way round, to paint thereal world with the digitalinformation
The key idea behind it was tofree the pixels from the confines
of digital devices.
Thus evolved the Head-Mounted Projector.

q Smart PhoneoAn internet enabled smart phone is
necessary to process the data.o As the smart phone is the open source, aprogram to process the data need to bedeveloped.o The software searches the web andinterprets the hand gestures.
q Color Markerso They are at the tips of the users
Fingers & help the camera torecognize the hand gestures.o The movements and arrangementsofthese markers are interpreted andthey act as instructions for the
projectedapplication interfaces.

v Playing with paper
Why only computers, we canplay with papers.
We can take a part of adocument putting
over another paper and we canevenmodify the paper and print it.So the work flow is moreintuitive.
In a more dynamic way you canpinch the information on the
paper to your system.

v Third EyeMultiple viewers can seedifferent things on a same
display screen at the sametime.
A public sign board candisplay information in different
languages at the same time.
We need not have the splitscreen in games now.
A public display can showsecret messages or patterns.
In the same movie theatre,people can see different end ofa suspense movie.

Limitations
Requires high speed internet whichis costly for general use.
Post processing can occur however.
There exists hardware limitations
of the devices.

Future
EnhancementsTo get rid of color markers.
To incorporate camera and projector inside mobilecomputing devices.
Whenever we place pendant- style wearable device ontable, it should allow us to use the table as a multi-touchuser interface.
Applying this technology in various interest like gaming ,
education systems etc.,
To have 3-dimensional gesture tracking.
To make sixth sense work as a fifth sense for the disabled
person.

ConclusionImagination is the only limit for such technologies.
It is a sense that would give seamless and easy accessto the Meta information.
We can have our digital world with us wherever we goand we can start using any surface around us as aninterface.
Actually ,the hardware is not that hard to
manufacture. The open source software is going to bemade available.
So the technology can reach masses than staying to
laboratories or environments.
