Pranav Mistry is a PhD student in the Fluid Interfaces Group at MIT’s Media Lab and is the inventor of SixthSense, a wearable device that enables new interactions between the real world and the world of data.

When I saw this talk I was absolutely blown away and began thinking how far multi-touch and gesture-based user interfaces have evolved. Interestingly in Pranav’s SixthSense demo, the concept of a screen-based UI is largely redundant.

This also got me thinking about the creation of augmented realities (e.g. Layar); as smartphones and Web-enabled mobile devices become increasingly more sophisticated and powerful, the distinction between our physical world and the digital world becomes blurred.
