What Is SixthSense Technology?

SixthSense devices are wearable gestural interfaces that augment the physical world with digital information and lets us use natural hand gestures to interact with that information. Essentially, SixthSense extends our physical world by overlaying digital data onto our analog senses.

The pioneering SixthSense prototype developed by Pranav Mistry was a pendant-like apparatus worn around the neck. It contained a miniaturized projector, camera, mirror setup and color marker detection components. The builtin camera recognizes hand gestures and physical objects using computer vision technology.

How Does The SixthSense Technology Work?

The sixth sense interaction model is based on four fundamental principles – the ability to detect markers, gestures, objects and map projection.

The prototype SixthSense device uses color markers with unique patterns to detect surfaces like wall, table tops or sheets of paper. The camera analyzes video feed to track these color markers to accurately pinpoint where to project information. The gesture recognition component uses computer vision algorithms to interpret hand gestures. This allows users to control the projected digital overlay through intuitive hand movements. For example, drawing a rectangle in the air can take a picture.

Advanced object recognition techniques detect physical objects. Users can retrieve more information about objects they pick up or interact with by using hand postures. This bridges the gap between the real and virtual. Finally, the projector maps relevant digital information like texts, videos, graphics etc. directly onto environmental surfaces or onto hands and physical objects tagged with visual markers.

Capacities And Features Of SixthSense

Some of the amazing ways in which SixthSense augments everyday reality are:

Information Retrieval
