This technology would be great to many people!
"Robotic Adaptation to Humans Adapting to Robots, (Radhar), was an EU-funded initiative which ran from 2010 until this September. Ian Steadman writes for New Statesman that Radhar has created a semi-autonomous system for wheelchairs.
He says that a wheelchair that drives itself without any intervention wouldn't work. "A better method is to smooth out jerky journeys, estimating where it thinks its owner wants to go and making subtle alterations to the journey route that leaves the user feeling absolutely in control, without the sensation of being ferried around."
Radhar's system uses two Kinect cameras and an onboard computer to do just that.
One camera scans the surroundings and makes a map. The computer uses this to spot obstacles and generate possible routes.
The other camera scans the wheelchair user, "assuming that the destination correlates with the direction of gaze. It also recognises if someone has a part of their body sticking out to the side, and knows to warn of the danger of hitting something as a result".
