Sixth 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.It was developed by Pranav Mistry, a PhD student in the Fluid Interfaces Group at the MIT Media Lab.SixthSense comprises a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device
In this paper, I would like to acknowledge Mr. PranavMistry for thegreat and deep research work he has done in this field.
Camera: tracks the movement of the colored markers using movement algorithms.Colored Markers: Red, blue, green, and yellow tape worn on the users fingertips for tracking purposes.Projector: Projects stored data onto most any surface.Smart phone: needed for internet connection and computing power
The Sixth Sense technology contains a pocket projector, a mirror and a camera contained in a pendant-like, wearable device. Both the projector the camera and sensors are connected to a mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks users' hand gestures and physical objects using computer-vision based techniques.
Recognizes hand movementsExamples from online demonstrations:Make frame with hands: camera takes pictureGoogle map onto wallDraw circle on wrist: projects digital clockMovement of text book/web info onto pageAirline ticket updatesDraw @ symbol: check email for youMany more capabilities (it’s on youtube or TED website)

INTRODUCTION Sixth Sense is a wearable gestural interfacethat augments the physical world around us withdigital information and lets us use natural handgestures to interact with that information. Steve Mann is considered as the father of SixthSense Technology who made wearable computerin 1990. He implemented the Sixth SenseTechnology as the neck worn projector with acamera system (which Mann originally referred toas “Synthetic Synesthesia of the Sixth Sense”).
THEN HIS WORK WAS CARRIED FORWARD BY PRANAV MISTRY (PH.DSTUDENT IN THE FLUID INTERFACES GROUP AT THE MIT MEDIA LAB).
CAMERACOLORED MARKER.MOBILE COMPONENTMIRRORPROJECTORTHE DEVICES WHICH ARE USEDIN SIXTH SENSE TECHNOLOGYARE:
Camera Captures an object in view and tracks the user’s hand gestures It sends the data to smart phone It acts as a digital eye, connecting you to the world of digitalinformation
Color Markers It is at the tip of the user’s fingers . Marking the user’s fingers with red, yellow, green, and blue tape helpsthe webcam recognize gestures The movements and arrangements of these makers are interpreted intogestures that act as interaction instructions for the projected applicationinterfaces.
Mirror The usage of the mirror is significant as the projector danglespointing downwards from the neck.Smart Phone A Web-enabled smart phone in the user’s pocket processes the videodata Other software searches the Web and interprets the hand gesturesMIRROR
Projector The projector projects visual information enabling surfaces andphysical objects to be used as interfaces The project itself contains a battery inside, with 3 hours of batterylife. A tiny LED projector displays data sent from the smart phone onany surface in view–object, wall, or person.
Make a call You can use the Sixth Senseto project a keypad onto yourhand, then use that virtualkeypad to make a call.Call up a map With the map application wecan call up the map of ourchoice and then use thumbsand index fingers to navigatethe map
Check the time Draw a circle on your wrist toget a virtual watch that givesyou the correct timeCreate multimediareading experiences Sixth Sense can beprogrammed to project relatedvideos onto newspaperarticles you are reading
Get flight updates The system will recognize yourboarding pass and let you knowwhether your flight is on timeand if the gate has changed.Feed information onpeople The system will project relevantinformation about a person suchas what they do, where theywork, and so on.
Take pictures If you fashion your index fingersand thumbs into a square("framing" gesture), the systemwill snap a photo. After taking the desired numberof photos, we can project themonto a surface, and use gestures tosort through the photos, andorganize and resize them.
Drawing application The drawing application letsthe user draw on any surfaceby tracking the fingertipmovements of the user’s indexfinger.Zooming features The user can zoom in or zoomout using intuitive handmovements
Get product information Sixth Sense uses imagerecognition or markertechnology to recognizeproducts we pick up, then feedsus information on thoseproducts.Get book information The system can project Amazonratings on that book, as well asreviews and other relevantinformation
ADVANTAGES 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
DISADVANTAGES Hardware limitations of the devices, that wecurrently carry around with us. For example many phones will not allow theexternal camera feed to be manipulated in realtime. Post processing can occur however.
CONCLUSION Sixth Sense recognizes the objects around us, displayinginformation automatically and letting us to access it in anyway we need. The Sixth Sense prototype implements several applicationsthat demonstrate the usefulness, viability and flexibility ofthe system. The potential of becoming the ultimate "transparent" userinterface for accessing information about everythingaround us. Allowing us to interact with this information via naturalhand gestures
FUTURE ENHANCEMENTS To get rid of color markers. To incorporate camera and projector insidemobile computing device. To have 3D gesture tracking. To make Sixth Sense work as fifth Sense fordisabled person.
