Paralyzed people have learned to control a wheelchair with the power of thought.

In Texas, scientists have created a wheelchair that paralyzed people can control with their minds. Some volunteers achieved 98% accuracy after the training course. Paralyzed people controlled the direction of the wheelchair by thinking about the movement of body parts. For example, thinking about hands for turning left or legs for turning right. The computer read the volunteers' neural signals and turned them into wheelchair commands. Initially, patients controlled the wheelchair with an accuracy of 43-55%. After training, some had an indicator of 98%. Each volunteer trained three times a week for 2-5 months.
