Recently, Ron Mukherjee forwarded me an amazing link on game changing technology from MIT Media Lab. Am sharing the link and video here. At this time it is not clear how far away this is from commercial application though they expecting the cost already to be same as a good mobile phone. But whenever it comes the applications suggested in the video are only a limited view of the enormous possibilities it opens up. They have linked a mobile with camera with video projection and built intelligence in the system to resolve and take decisions on the basis of video imagery and actions of 4 fingers. So a simple view is the projector projects a key board on any surface and as you touch the keyboard - -the camera picks up and takes the alphabets touched as input to any computing device/telephone etc. The thing is getting developed by a person of Indian origin - Pranav Mistry. Enjoy.
