SIXTH SENSE TECHNOLOGY
ABSTRACT
Sixth sense is a wearable gestural interface that augments the physical world around us with digital information and use natural hand gestures to interact with that information. Sixth Sense Technology is a mini-projector coupled with a camera and a cellphonewhich acts as the computer and connected to the Cloud, all the information stored on the web.Pranav Mistry,28 year old,of Indian origin is the mastermind behind the sixth sense technology.The device sees what we see but it lets out info that we see but it lets out info that we want to know while viewing the object. The camera recognizes objects around a person instantly, with the microprojector overlaying the information on any surface, including the object itself or hand. Also can access or manipulate the information using fingers. Make a call by extending hand on front of the projector and numbers will appear for to click. The device has a huge number of applications , it is portable and easily to carry as can wear it in neck. The drawing application lets user draw on any surface by observing the movement of index finger. Mapping can also be done anywhere with the features of zooming in or zooming out. The camera also helps user to take pictures of the scene is viewing and later can arrange them on any surface. Some of the more practical uses are reading a newspaper. Reading a newspaper and viewing videos instead of the photos in the paper or live sports updates while reading the newspaper. The device can also tell arrival, departure or delay time of air plane on tickets.

INTRODUCTION
1.1 Overview
We've evolved over millions of years to sense the world around us. When we encounter something, someone or some place, we use our five natural senses to perceive information about it; that information helps us make decisions and chose the right actions to take. But arguably the most useful information that can help us make the right decision is not naturally perceivable with our five senses, namely the data, information and knowledge that mankind has accumulated about everything and which is increasingly all available online. Although the miniaturization of computing devices allows us to carry computers in our pockets, keeping us continually connected to the digital world, there is no link between our digital devices and our interactions with the physical world. Information is confined traditionally on paper or digitally on a screen. SixthSense bridges this gap, bringing intangible, digital information out into the tangible world, and allowing us to interact with this information via natural hand gestures.SixthSense frees information from its confines by seamlessly integrating it with reality, and thus making the entire world your computer. Sixth Sense technology is the science of tomorrow with the aim of connecting the digital world with the physical world seamlessly, eliminating hardware devices. Mistrys flirtations with the digital world began in the early 2000s when he pieced together four mouse rollers with pulleys and springs to give shape to a motion sensing device. It is similar to Telepointer, a neck worn projector/camera system developed by Media Lab student Steve Mann (which Mann originally referred to as "Synthetic Synesthesia of the Sixth Sense"). What the researchers have done is combine a number of standard gadgets including a webcam, projector, and mobile phone, to form a brand new interaction experience. In its current form the battery-powered projector is attached to a hat, the webcam is hung around the neck (or also positioned on a hat), and the mobile phone provides the connection to the Internet. The wearer uses hand gestures combined with the gadgets to perform actions. So, for example, they could make a circle over their wrist with the fingers of one hand. WUW would recognize this action and project a clock face on to their wrist. Make a picture frame with both your hands and WUW will take a picture as if it was a

camera. Stand near a wall and you can get a projected desktop allowing you to open applications, view the pictures youve taken, or surf the Net.
1.2 THE MASTER MIND
Pranav Mistry, 28 year old, of Indian origin is the mastermind behind the sixth sense technology. Born in Palanpur, Gujarat he received his Bachelors of technology in computer science and engineering from India and later received masters in design from MIT Boston. He invented Sixth Sense / WUW ( Wear UR World) which is a wearable gestural , user friendly interface which links the physical world around us with digital information and uses hand gestures to interact with them. Pranavs eagerness to pop pixels out of the digital world into the real world led to the birth of Sixth Sense technology. Currently he is a PhD student at MIT and he won the Invention of the Year 2009 - by Popular Science. The device sees what we see but it lets out information that we want to know while viewing the object. It can project information on any surface, be it a wall, table or any other object and uses hand / arm movements to help us interact with the projected information. The device brings us closer to reality and assists us in making right decisions by providing the relevant information, thereby, making the entire world a computer.

HISTORY
The exploration of this sixth sense technology started with a question why cant we use a computer to interact with physical world. This literally started with a mouse that comes with a ball in it and two rollers that actually guide the movement. So taking out rollers from another mouse totally we have four rollers. Using these system interface device was formed. With this you do in physical world will be reflected in the digital world. With this initially a pen to draw 3- dimensions in digital world was made that can help designers and architects not only think but they can actually draw so that it is more intuitive to use that way.

Not only this, the reverse process is made possible. Initially the device started with a helmet consisting of the camera, projector and colored markers .Later it was converted into a form so that it is easy to use it by wearing around the neck. Sixth Sense bridges this gap, bringing intangible, digital information out into the tangible world, anda l l o wi n g u s t o i n t e r a c t wi t h t h i s i n f o r ma t i o n v i a n a t u r a l h a n d g e s t u r e s .

3.1 What is Sixth Sense?
Sixth Sense in scientific (or non-scientific) terms is defined as Extra Sensory Perception or in shortESP. It involves the reception of information not gained through any of the five senses. Nor is ittaken from any experiences from the past or known. Sixth Sense aims to more seamlessly integrate o n l i n e i n f o r ma t i o n a n d t e c h i n t o e v e r yd a y l i f e . B y ma k i n g a v a i l a b l e i n f o r ma t i o n n e e d e d f o r decision-making beyond what we have access to with our five senses, it effectively give users a sixth sense.
3.2 Earlier Sixth Sense Prototype
MIT group, which includes seven graduate students, were thinking about how a person could be more integrated into the world around them and access information without having to do something l i k e t a k e o u t a p h o n e . Th e y i n i t i a l l y p r o d u c e d a wr i s t b a n d t ha t wo u l d r e a d a R a d i o F r e q u e n c y Identification tag to know, for example, which book a user is holding in a store.They also had a r i n g t h a t u s e d i n f r a r e d t o c o m mu n i c a t e b y b e a c o n t o s u p e r ma r k e t s ma r t s h e l v e s t o g i v e yo u information about products. As we grab a package of macaroni, the ring would glow red or green to tell us if the product was organic or free of peanut traces whatever criteria we program into the system. They wanted to make information more useful to people in real time with minimal effort in a way that

doesnt require any behavior changes. The wristband was getting close, but we still had t o t a k e o u t o u r c e l l p h o n e t o l o o k a t t h e i n f o r ma t i o n . T h a t s wh e n t h e y s t r u c k o n t h e i d e a o f accessing information from the internet and projecting it. So someone wearing the wristband could pick up a paperback in the bookstore and immediately call up reviews about the book, projecting them onto a surface in the store or doing a keyword search through the book by accessing digitized pages on Amazon or Google books. They started with a larger projector that was mounted on a helmet. But that proved cumbersome if someone was projecting data onto a wall then turned to speak to friend the data would project on friends face.
3.3 Recent Prototype
Now they have switched to a smaller projector and created the pendant prototype to be worn around the neck. The Sixth Sense prototype is composed of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant-like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the users pocket. We can very well consider the Sixth Sense Technology as a blend of the computer and the cell phone. It works as the device associated to it is hanged around the neck of a person and thus the projection starts by means of the micro projector attached to the device. Therefore, in course, you turn out to be a moving computer in yourself and the fingers act like a mouse and a keyboard. The prototype was built from an ordinary webcam and a battery-powered 3M projector, with an attached mirror all connected to an internet-enabled mobile phone. The setup, which costs less than $350, allows the user to project information from the phone onto any surface walls, the body of another person or even your hand. Mistry wore the device on a lanyard around his neck, and colored Magic Marker caps on four fingers (red, blue, green and yellow) helped the camera distinguish the four fingers and recognize his hand gestures with software that Mistry created.

SIXTH SENSE:THE DEVICE
Sixth Sense is a mini-projector coupled with a camera and a cellphonewhich acts as the computer and your connection to the Cloud, all the information stored on the web. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the users pocket.
Software:
Software program processes the video stream data captured by the camera Pranav Mistry says the SixthSense software will be open source. As far as this seems to be a little set of items, there will not be user interfaces or much advanced programs for the users. There will be much harder and secured coding inside the device to make sure the security of the software. It will be interesting to know the new language for coding for a SixthSense device.
Hardware:
In order to control the SixthSense, it requires some advance hardware as it appears to be. In some of the public presentations, the presenter was wearing some controlling devices including color markers, Camera and projector. They has to be compact and easily controllable. However the hardware integration of SixthSense

technology is quite innovative since they have manage to develop camera and pen like day to day objects. Projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces Camera recognizes and tracks user's hand gestures and physical objects using computer-vision based techniques. Colored markers (visual tracking fiducials) placed at the tip of the users fingers using simple computer-vision techniques helps the webcam to track the movement of fingers. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces Mobile device may be a laptop, PDA, smart phones etc. These are connected to other hardware devices and sends information to projector for projection. The important thing is that the device is a mobile device. Means, it is so light that we can take it with us where ever we want to. It is as small as a cell phone and is so simple to use.

5.1.1 Camera
A webcam captures and recognizes an object in view and tracks the users hand gestures using computer-vision based techniques. It sends the data to the smart phone. The camera, in a sense, acts as digital eye, seeing what the user sees. It also tracks the movements of the thumbs and index fingers of both of the user's hands. The camera recognizes objects around you instantly, with the micro-projector overlaying the information on any surface, including the object itself or your hand.
5.1.2 Projector
Also, a projector opens up interaction and sharing. The project itself contains a battery inside, with3 h o u r s o f b a t t e r y l i f e .

SIXTH SENSE TECHNOLOGY 5.2 Working
The hardware that makes Sixth Sense work is a pendant like mobile wearable interface It has a camera, a mirror and a projector and is connected wirelessly to a Bluetooth or 3G or Wi-Fi smart phone that can slip comfortably into ones pocket . The camera recognizes individuals, images, pictures, gestures one makes with their hands Information is sent to the Smartphone for processing The downward-facing projector projects the output image on to the mirror. Mirror reflects image onto the desired surface Thus, digital information is freed from its confines and placed in the physical world. The entire hardware apparatus is encompassed in a pendant-shaped mobile wearable device. Basically the camera recognizes individuals, images, pictures, gestures one makes with their hand sand the projector assists in projecting any information on whatever type of surface is present inf r o n t o f t h e p e r s o n . Th e u s a g e o f t h e mi r r o r i s s i g n i f i c a n t a s t h e p r o j e c t o r d a n g l e s p o i n t i n g downwards from the neck. To bring out variations on a much higher plane, in the demo video which was broadcasted to showcase the prototype to the world, Mistry uses colored caps on his fingers so that it becomes simpler for the software to differentiate between the fingers, demanding various applications. The software program analyses the video data caught by the camera and also tracks down the locations of the colored markers by utilizing single computer vision techniques. One can have any number of hand gestures and movements as long as they are all reasonably identified and differentiated for the system to interpret it, preferably through unique and varied fiducially. This is possible only because the Sixth Sense device supports multi-touch and multiuser interaction. MIT basically plans to augment reality with a pendant Pico projector: hold up an object at the store and the device blasts relevant information onto it (like environmental stats, for instance), which can be browsed and manipulated with hand gestures. The "sixth sense" in question is the internet, which naturally supplies the data, and that can be just about anything -- MIT has shown off the device p r o je c t i n g i n f o r ma t i o n a b o u t a p e r s o n

It's pretty interesting technology that, like many MIT Media Lab projects, makes the wearer look like a complete dork if the projector doesn't give it away, the colored finger bands the device uses to detect finger motion certainly might. The idea is that Sixth Sense tries to determine not only what someone is interacting with, but also how he or she is interacting with it.The software searches the internet for information that is potentially relevant to that situation, andt h e n t h e p r o je c t o r t a k e s o v e r . A l l t h e wo r k i s i n t h e s o f t wa r e ," s a ys D r M a e s . " Th e s ys t e m i s constantly trying to figure out what's around you, and what you're trying to do. It has to recognize the images you see, track your gestures, and then relate it all to relevant information at the same time." The software recognizes 3 kinds of gestures: Multi touch gestures, like the ones you see in Microsoft Surface or the iPhone -- where you touch the screen and make the map move by pinching and dragging. Freehand gestures, like when you take a picture, b e c a u se o f c u l t u r e , I d o a N a ma s t e g e s t u r e t o s t a r t th e projection on the wall. Iconic gestures, drawing an icon in the air like, whenever I draw a star, show me the weather. When I draw a magnifying glass, show me the map. You might want to use other gestures that you use in everyday life. This system is very customizable. The technology is mainly based on hand gesture recognition, image capturing, processing, and manipulation, etc. The map application lets the user navigate a map displayed on a nearby surface using hand gestures, similar to gestures supported by multi-touch based systems, letting the user zoom in, zoom out or pan using intuitive hand movements. The drawing application lets the user draw on any surface by tracking the fingertip movements of the users index finger.

APPLICATIONS
6.1 Motion Picture
The innovative camera is something that got applauds of the crowd in the demonstration. Four rubber rings in the four fingers two in each can be used do draw a rectangular. It will be the area covered by the photograph. Then the photos can be taken to any interface for editing, managing the galleries and sharing. This is much controversial. There is an inbuilt storage device where the data can be stored. When using a surface, the whole data is taken into that surface and stored in the device after the editing. And also the capturing device being so small like 4 rubber rings can be used to capture the photos of any location. Example using 2 fingers to send 5 seconds, 3 fingers to send10 seconds likewise it can be done. There are so many new applications to be developed in the near future. A remote controller for media devices can be implemented to be worked with fingers using this technology. Except having the remote controller to send fast forward, rewind or next or previous options, a Sixth Sense device can be used. The current process of sending fast-forward or rewind with advanced options. Many games can be made using this technology. A car race using an imaginary steering wheel will be an attractive application. The player will have to drive the vehicle as a real one using his arms. The Sixth Sense tool kit will be a good replacement for the XBOX game kit and it will not be much expensive as it is said.
6.2 Capture Photos with fingers

CONCLUSION
Using this technology Finally one gets a taste of the world of Harry Potter.
Sixth Sense technology is the science of tomorrow with the aim of connecting the digital world with the physical world seamlessly, eliminating hardware devices. Mistrys flirtations with the digital world began in the early 2000s when he pieced together four mouse rollers with pulleys and springs to give shape to a motion sensing device. This device interprets gestures made in the physical world and replicates them in the digital world. Next he gave the omni-present sticky note a digital makeover. Digitized sticky notes (or Quickies) set as reminders can jog your memory regarding tasks through an SMS or E-mail. Jotting down a question on a quickie prints you the answer. All it takes to message someone on their cell phone is write a note on a quickie. Next in tow for Mistry was a pen that can draw in 3D (a technology popular by the name Inktuitive). With the invention of intuitive computer interfaces, the digital and physical worlds came together closer than ever. One just has to place an object (anything from a flight boarding pass to a key) on a Tangible Public Map (TaPuMa) on its horizontal smart screen to get inside-out information about it. Keep a coffee cup on a particular spot on the map and a whole range of cafs in the area is brought to you on a platter. Pranavs eagerness to pop pixels out of the digital world into the real world led to the birth of Sixth Sense technology. All you have to do to get seamlessly connected with the digital world is wear simple pendant-like equipment consisting of a camera and a portable battery-powered projection system with a mirror (a more modish version is just round the corner). The device (now known as the Sixth Sense Device) when connected to a cell phone acts as a computation and communication tool. The camera tracks hand gestures and helps gather meta information (information from the surroundings) and articulates it with the digital domain. The potential of becoming the ultimate transparent user interface for accessing information about everything around us.
