WHY SIXTH SENSE ???? Here by Physical world is painted with the digital information. You can carry your digital world with you wherever you go. You can start with any wall or any surface as an interface even your palm.

INTRODUCTIONSixth Sense is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information.

Sixth Sense bridges the gap by bringing intangible, digital information out into the tangible world, and allowing us to interact with this information via natural hand.

CONTD.It was developed by Pranav Mistry, a PhD student in the Fluid Interfaces Group at the MIT Media Lab. Sixth Sense comprises a pocket projector, a mirror, a camera and a smart phone. The hardware components are coupled in a pendant like mobile wearable device.

COMPONENTSCamera Projector

Mirror Colored Markers Smart Phone/laptop


.Captures an object in view and tracks theusers hand gestures. .It sends the data to smart phone. .It acts as a digital eye, connecting you to the world of digital information.

PROJECTOR The projector projects visual information enabling surfaces and physical objects to be used as interfaces. It displays data sent from the smart phone on any surface in viewobject, wall, or person.



The usage of the mirror is significant as the projector angles pointing downwards from the neck. .

COLOR MARKERS At the tip of the users fingers. Helps the webcam to recognize the gestures. The movements and arrangements of these makers are interpreted into gestures.

SMART PHONE A web enabled smart phone in the users pocket processes the video data. Other software searches the web and interprets the hand gestures.

CAPABILITIESRecognizes hand movements Examples from online demonstrations:

Make frame with hands: camera takes picture Google map onto wall Draw circle on wrist: projects digital clock Movement of text book/web info onto page Airline ticket updates Draw @ symbol: check email for you Many more capabilities (its on youtube or TED website)


CHECK THE TIME Check the time just by drawing a circle on the wrist. WATCH VIDEOS Watch related videos on the newspaper articles you are reading.

MAKE A CALL To make a call, virtual keypad is shown on your palm.

CALL UP A MAP Call up the map and use thumbs & index fingers to navigate through.ZOOMING FEATURES Zoom in & zoom out using intuitive hand movements. DRAWING APPLICATION Drawing application by tracking fingertip movements.

PEOPLE INFORMATION Projects relevant information regarding a person.TAKE PICTURES Click pictures just by forming framing gesture.

ORGANIZE PHOTOS Organize, sort & resize pictures by projecting them on a surface.

GET PRODUCT INFORMATION Get product information by using image recognition technology.BOOK INFORMATION Get book reviews, ratings & other relevant information. GET FLIGHT UPDATES Get flight updates regarding timing of the flight.

ADVANTAGES Connectedness between world and information. Data access directly from machine in real time. Mind map the data anywhere.

Portable. Inexpensive.

Cost: ~350$ Software will be open source


CONCLUSIONIntegrating information to everyday objects will not only help us to get rid of the digital divide, but will also help us in some way to stay human, to be more connected to our physical world.
