According to him, some insurance companies used the technology to tell if the insured driver was drowsy before an accident.

On its medical application, he said: "Until recently, we had no good technique; but with functional MRI, it's possible to instruct patients to imagine they are doing something, like playing tennis, and the results show her brain was lighted up. By knowing that, doctors got to understand that the patient was not brain dead and still had some consciousness."

In the world which could be better perceived, robotics will play a role caring the sick and old, said Ralph Hollis, research professor of the Carnegie Mellon University's robotics institute.

The university was introducing at the event its "ballbot", which is a robot balancing and moving on a ball instead of the conventional kind of wheeled drive for robots.

Ballbot moves from place to place by managing its center of mass with respect to its point of support on the floor. "It can provide many useful services especially for the elderly or physically challenged in their everyday work and home environments," he said.

He projected a $30 billion market for such service robotics.
