BIOS - Bidirectional Input/Output System is a custom-built helmet with sixteen electrodes that are attached to a spectator’s head, a head-mounted display, an EEG device, and a computer. The display shows images that are synthesized from impulses generated by the spectator’s brain, which are in reaction to the images shown a moment before, thus creating a feedback loop.
