Cheap gadget lets you steer a wheelchair with your eyes
People who can't move their arms and legs will soon be able to attach a £50 gadget to their wheelchair along with their laptop to allow them to drive around using just their eyes – without having to stare at any controls.
The New Scientist reported that Aldo Faisal at Imperial College London and his colleagues have developed software that uses subtle eye movements to distinguish when a person is looking around and when they want to move. "Current eye tracking software doesn't allow you to look around while moving," says Faisal. "And technologies that use brainwaves to control wheelchairs aren't common because it takes many months to train a person to use them, and then you need to really concentrate to move – it's not natural."
The team will showcase the technology at the Imperial Festival this weekend in London.
