We've seen this idea tested in the lab, now we see a working model in action.
The wheelchair driver wears a skull cap populated with electrodes and sends signals through it by concentrating on where he or she wants to go, choosing from a selection of destinations displayed on a screen. The list includes, for example, kitchen, bedroom, bathroom, and so on. In a matter of seconds, the chair heads for the chosen destination. The program contains a plan of the house but also uses laser beams in order to avoid obstacles.
Wheelchairs equipped with this kind of thought-command system could be on the market in ten years, according to the developers. They are expected to cost about 10% more than standard motorized models.
