Synopsis: Researchers demonstrate that tetraplegic users could operate mind-controlled wheelchairs in a natural, cluttered environment after training for an extended period. Tetraplegic people were recruited for the longitudinal study and underwent training sessions thrice weekly for 2 to 5 months. The participants wore a skullcap that detected their brain activities through electroencephalography (EEG), which would be converted to mechanical commands for the wheelchairs via a brain-machine interface device. By the end of the training, all participants were asked to drive their wheelchairs across a cluttered hospital room. They had to go around obstacles such as a room divider and hospital beds, which were set up to simulate the real-world environment.
