How GPUs Help People with Disabilities Race Using Brain Signals

GPUs aren’t quite ready to help people with severe disabilities shed their wheelchairs, but they’ve helped researchers take a big step closer. At this fall’s Cybathlon آ— dubbed the world’s first "bionic Olympics," and held in Zurich آ— a team of 40 students from Imperial College of London developed technology that let competitors participate in a brain-computer interface race. The participants, referred to as pilots, wear electroencephalogram (EEG) caps, which record the electrical activity of the brain and are connected to computers running GPU-powered machine learning algorithms. Normally unable to engage in physical competitions due to spinal cord injuries, neurological diseases or other trauma, the pilots raced in a video game, with the algorithms interpreting their brain impulses to control their digital avatars. The approach was the latest step in Aldo Faisal’s efforts to jettison the use of invasive brain implants to aid those with restricted movement, and instead rely on software made smarter via machine learning.
