INTRODUCTION
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 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
WHY SIXTH SENSE?
Camera
Projector
The projector projects visual information enabling surfaces and physical objects to be used as interfaces
The project itself contains a battery inside, with 3 hours of battery life.
A tiny LED projector displays data sent from the smart phone on any surface in view–object, wall, or person.
Mirror
The usage of the mirror is significant as the projector dangles pointing downwards from the neck.
Smart Phone
A Web-enabled smart phone in the user’s pocket processes the video data
Other software searches the Web and interprets the hand gestures
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.
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 smart phone that can slip comfortably into one’s 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 on to the desired surface
Thus, digital information is freed from its confines and placed in the physical world
RELATED TECHNOLOGIES
Augmented reality is a term for a live direct or indirect view of a physical real world environment whose elements are augmented by virtual computer generated imagery.
Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms.
Computer vision is the science and technology of machines that see. It is concerned with the theory behind artificial systems that extract information from images.
Radio Frequency Identification is basically an electronic tagging technology that allows the detection, tracking of tags and consequently the objects that they are affixed to.
