Powered chairs offer people with limited mobility the chance to be independent, since they can be controlled with an array of switches and pads. For some people though, unpredictable muscle spasms mean that driving can be time-consuming, stressful or dangerous. We try out a new device from Belgium that uses artificial intelligence to quickly learn a user’s profile, filtering out unintentional movements to provide a smooth experience, meaning more people than ever can steer their chairs and live more comfortably. And we find out how clothing can help autistic people communicate their feelings more easily.People Fixing The World from the BBC is about brilliant solutions to the world's problems.
