Idea to make something similar to the Sixth Sense technology

I was just thinking yesterday night on what could be a game changer in the Mobile Market, may be some application, features or anything. 

I came up with an idea that, something similar to sixth sense be implemented on the mobile phone. 'SixthSense' 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 is a technology developed by Pranav Mistry(PHd. MIT). For more details visit http://www.pranavmistry.com/projects/sixthsense/

In mobile, what we can do is near the camera we can have a projector kind of thing which can project, whatever is there on the mobile screen on a flat surface. The camera should be capable of recognizing the gestures of the hand where the focus is being made on the screen and should perform the same function on the mobile phone.

Well a lot has to be researched before I start, but its quite a good idea...2
