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.

The neckworn projector and camera combination was first

proposed by MIT Media Lab student Steve Mann. The concept was

further developed by Pranav Mistry, while he was also a student at

the MIT Media Lab.

SixthSense bridges the gap by bringing intangible, digital information

out into the tangible world, and allowing us to interact with this

information via natural hand

SixthSense comprises a pocket projector, a mirror and a camera. The

hardware components are coupled in a pendant like mobile wearable

device

Introduction

Sixth Sense technology is the science of tomorrow with the aim of connecting the digital world with the physical world seamlessly, eliminating hardware devices

The 5 senses Here comes the sixth sense

The SixthSense prototype is comprised 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 user’s pocket.

Components

The Main Components:

Camera

Projector

Mirror

Mobile Component

Colored Markers

The camera is the key input device of the SixthSense system. The camera acts as a digital eye of the system. It basically captures the scene the user is looking at. The video stream captured by the camera is passed to mobile computing device which does the appropriate computer vision computation.

The major functions of the camera can be listed as: Captures user’s hand movements and gestures

(used in reorganization of user gestures) Captures the scene in front and objects the user

is interacting with (used in object reorganization and tracking)

Takes a photo of the scene in front when the user performs a ‘framing’ gesture

Captures the scene of projected interface (used to correct the alignment, placement and look and feel of the projected interface components)

Camera

The projector is the key output device of the SixthSense system. The projector visually augments surfaces, walls and physical objects the user is interacting with by projecting digital information and graphical user interfaces. The mobile computing device provides the projector with the content to be projected. The projector unit used in prototype runs on a rechargeable battery.

The major functions of the projector can be listed as:

Projects graphical user interface of the selected application onto surfaces or walls in front.

Augments the physical objects the user interacting with by projecting just-in-time and related information from the Internet.

Projector

The mirror reflects the projection coming out from the projector and thus helps in projecting onto the desired locations on walls or surfaces. The user manually can change the tilt of the mirror to change the location of the projection. For example in application where the user wants the projection to go on the ground instead of the surface in front, he can change the tilt of the mirror to change the projection. Thus, the mirror in the SixthSense helps in overcoming the limitation of the limited projection space of the projector.

Mirror

MicrophoneThe microphone is an optional component of the SixthSense. It is required when using a paper as a computing interface. When the user wants to use a sheet of paper as an interactive surface, he or she clips the microphone to the paper. The microphone attached this way captures the sound signals of user’s touching the paper. This data is passed to computing device for processing. Later, combined with the tracking information about user’s finger, the system is able to identify precise touch events on the paper.

The SixthSense system uses a mobile computing device in user’s pocket as the processing device. The software program enabling all the features of the system runs on this computing device. This device can be a mobile phone or a small laptop computer. The camera, the projector and the microphone are connected to this device using wired or wireless connection. The detail of the software program that runs on this device is provided in next section. The mobile computing device is also connected to the Internet via 3G network or wireless connection.

Mobile computing device

Color Markers

It is at the tip of the user’s fingers .

Marking the user’s fingers 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.

These are the basic pieces that you should buy. We can choose any brand, and the following list are those items that worked well for Pranav Mistry:

Pico-Projector◦ Laser

AAXA ~$110 Microvision ~$200

◦ L.E.D 3M MPro110 ~$270

Camera◦ Logitech QuickCam Pro for notebooks ~$23

Microphone◦ Microphone of Logitech QuickCam pro for notebooks ~$23

A mirror assembly◦ Front faced mirror is best, 1”X1” first surface mirror (this can be

purchased from anywhere, i.e. Ebay). Laptop Computer: Any Windows computer (this will act as the

mobile computing device)

Suggested Products

Working principle

The prototype system runs on windows platform and majority of the code is written in C++ and C#.

WUW v0.1 beta WUW_v0.1 is the beta version of SixthSense code (WUW stands

for Wear Ur World, a former name of the project). This version runs on Windows.

Microsoft DirectX Microsoft Visual Studio. Adobe Flash Player Microsoft Outlook

Software

Draw: The red marker (M) draws when the yellow marker (N) is hidden. When both the markers are visible you can move the mouse pointer to select different colours or eraser, etc.

Photo: Make a rectangle with your pointer fingers and thumbs and when the gesture is recognized, the countdown starts. Remove you hands from the camera frame to capture the desired photo. (The countdown lasts for 3 secs)

Gallery: Displays the photos that you have taken

Mail: Displays a list of email from outlook (required that MS Outlook be running for this to work)

Stock: Displays 16 stocks values real time, use the slider at the bottom of the projected display to set the time scale.

Effects: Play with beautiful wavy lines and explore your imagination.

Newspaper: It projects newspaper stories and related videos from YouTube or other web sites, directly onto the surface of the paper.

Book: For book-recognition, the program gets activated with a gesture, and the system snaps a photo of the book, compares it with book-cover images it finds online, computes a match, and retrieves and projects the ratings

Clock: An Analog clock will be projected by doing a circle gesture.

Working of Apps

APPLICATIONS

Make 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

Check the time

Draw a circle on your wrist to get a virtual watch that gives you the correct time

Create multimedia reading experiences

Sixth Sense can be programmed to project related videos onto newspaper articles you are reading

Drawing application

The drawing application lets the user draw on any surface by tracking the fingertip movements of the user’s index finger

Zooming features

The user can zoom in or zoom out using intuitive hand movements

Get product information

Sixth Sense uses image recognition or marker technology to recognize products we pick up, then feeds us information on those products

Get book information

The system can project Amazon ratings on that book, as well as reviews and other relevant information

v

Take pictures

If you fashion your index fingers and thumbs into a square ("framing" gesture), 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 organize and resize them.

ADVANTAGES

Supports multi-touch and multi-user interaction

Portable

Connectedness between world and information

Cost effective

Data access directly from machine in real time

Mind map the idea anywhere

Press Coverage from all over the world

SixthSense prototypes cost approximately $350 to build (not including the computer), the main cost being the micro-projector. Mistry had announced in Nov 2009 that the source code will be released with an open source licence. The open source code for the project can be found at SixthSense Google Code and SixthSense Github Repo. The source code is currently being ported into Java from C# to allow the developers to make mobile ports.
