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.

THE DEVICES USED IN SIXTH SENSE TECHNOLOGY

ARE:

CAMERA.

COLOURED MARKERS.

MOBILE TECHNOLOGY.

MIRROR.

PROJECTOR.

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);

IR CODING

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


10/23

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.

COLOUR MARKERS

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.


15/23

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.

16/23

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.


19/23

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.
