DEFINITION
Sixth sense is a wearable gestural interface.
It mixes real world with the digital information and lets us use handgestures to interact with the Digital information.
It uses hand gestures to interact with the information.
Steve mann was the first person to implement sixth sense
technology as the neck worn projector with a camera system.
It was developed by pranav mistry a phD student at MIT media lab.

GESTURE RECOGNITION
STRUCTURED LIGHT
SENSING CIRCUIT.
Gesture recognition is the
inverse process of convertingthe 2D image to 3D format .
Infra red coding is adopted
in structured light sensing
circuit.
The light in the surrounding
is divided into dark and white
bands.
These bands are converted
into digital data and sent to
smartphone.

Coding segment in gesture capture
Code-
addpath('Mex') //It adds folders to top or bottom of
program//
SAMPLE_XML_PATH='Config/SampleIRConfig.xml';//Extensible markup language
Used for machine aswell human reading it is an markup
Language.
%Start the Kinect Process
KinectHandles=mxNiCreateContext(SAMPLE_XML_PATH
);//this function connects to the microsoft image ordata kinect file and uses it//.
figure;//Array with pointers to kinect node objects
generated//.
J=mxNiInfrared(KinectHandles); J=permute(J,[2
1]);//Rearranging of dimensions of array is done//.
h=imshow(J,[0 1024]);//displays image in handle
graphics figure 0 and 1 for IR//.for i=1:9000//length:depth view 3D data in IR form//.
J=mxNiInfrared( KinectHandles); J=permute(J,[2 1]);
set(h,'Cdata',J);//Handle graphics interface in matlab//.
end
% Stop the Kinect Process//closes kinect objects
connected to kinect streams//.
mxNiDeleteContext(KinectHandles);

Captures the objects in view and tracks the users hand
gestures.
It sends the data to smart phone.
It acts as a digital eye connecting you to a world of
Digital information.
CAMERA

It is at the tip of users fingures.
Marking the users fingures with red,yellow,green and
blue tape helps the webcam recognize gestures.
The movements and arrangements of these makers are
interpreted into gestures that act as interaction instructions
for the projected application interfaces.

MAKING A CALL
You can use the Sixth Sense to
project a keypad onto your hand,
then use that virtual keypad to
make a call.
CALL UP A MAP
With the map application we
can call up the map of our choice
and then use thumbs and index
fingers to navigate the map.

CREATE MULTIMEDIA
READING
EXPERIENCE.
Sixth Sense can be programmed to
project related videos onto newspaper
articles you are reading.
FEED INFORMATION
ON PEOPLE
The system will project
relevant information about a
person such as what they do,
where they work, and so on.

TAKE PICTURES
If you fashion your index
fingers and thumbs into a
square the system will snap a
photo.
After taking the desired number of
photos, we can project them onto a
surface, and use gestures to sort
through the photos, and organizeand resize them.

DRAWING
APPLICATION
The drawing application lets theuser draw on any surface by
tracking the fingertip movements
of the usersindex finger.
ZOOMINGTECHNOLOGY
The user can zoom in or zoom out
using intuitive hand movements.

Portable.
Support Multi touch and Multi user interaction.
Cost Effective(300$).
Data access directly from the machines in real time.
Mind map the idea anywhere.
Open Source Software.
ADVANTAGES

20/23
Sixth Sense recognizes the objects around us, displaying informationautomatically and letting us to access it in any way we need.
Allowing us to interact with this information via natural hand gestures.
The Sixth Sense prototype implements several applications that
demonstrate the usefulness, viability and flexibility of the system.
