The Cybathlon competition has been the first ever international championship for disabled individuals competing with assistive devices1. Held in Zürich, Switzerland in October 2016, it featured the Brain-Computer Interface (BCI) race as one of its most innovative disciplines2. The Cybathlon BCI race aspired to accelerate the development of BCI technology, promote end-user and public awareness, as well as to attract funding agencies and entrepreneurs. The discipline consisted of a virtual race game called “Brain Runners” (Figure 1), where four brain-controlled avatars could be pushed towards the finish line by means of (up to) three mental commands. These commands should be issued by the “pilot” exclusively on suitable color-coded areas (spin on cyan, jump on magenta and slide on yellow “pads”). Pilots should also be able to “idle” and avoid any command delivery on additional white pads. Erroneous commands would slow down the pilot’s course down the race track, which consisted of sixteen consecutive pads (four of each type) placed in random order. Brain Runners has been designed to assess all those skills that are considered crucial to allow BCI in real-world scenarios, while also being attractive to Cybathlon’s live audience. Eleven teams representing BCI research groups from around the world have participated in the competition.
