Japanese auto manufacturer Toyota has taken its brainwave interface technology to the next level by unveiling a wheelchair controlled by the user's thoughts, with a revolutionary system allowing "nearly instant" movement forward, right, or left. Previous brainwave-controlled wheelchairs took several seconds to read signals from the user's brain. Toyota's creation, below, takes a mere 25 milliseconds to read signals from a brain-scan electroencephalograph (BSE).

A cap worn by the user relayes electrical impulses from the brain to an on-board computer that analyzes them almost instantly and transmits commands controlling the chair in order to move it forward or turn it. The wheelchair isn't quite so easy to stop, however: Its user must inflate one cheek to trigger it to halt.
