You have got to see this! MS is working on a new technology that promises to revolutionize the human computer interface. Project Natal is a hands-free motion sensitive controller integrated with the Xbox system. You definitely want to check out the videos – here and here.
The ability for a person to use physical movements and immersively interact with the digital medium brings a live experience to us like never before. It boggles the mind to think how much learning and training would get influenced by the availability of technology like this. Now the only thing that remains, I guess, is the fourth dimensional simulated experience (feel the cool breeze, the ground shaking under your feet, the smells of the desert)!
What is incredible is the amazingly enhanced potential for live collaboration that you should see in the videos. This simply beats everything I have seen so far in terms of the possibilities it opens up. Wow!
