Valve's Chief Experimental Psychologist, Mike Ambinder, will discuss brain-computer interface research at the upcoming GDC 2019 conference. Ambinder states that while brain-computer interfaces are currently just a theoretical technology, they have the potential to play a significant role in the future interaction between players and games. As computer interfaces become more natural, such as touchscreens and VR/AR headsets that can track head and hand movements, it becomes easier for users to convey their intentions to computers without the need to learn abstract input systems. The ultimate frontier of computer input could be brain-computer computing, where the brain could directly communicate with computers without any abstract I/O. Though direct brain I/O is still far off, recent progress in brain reading technology has shown great potential in changing the way we interact with machines and how machines interact with us. Ambinder's presentation will focus on the recent research and how it can benefit game developers. While the official description does not mention AR/VR specifically, the application of brain-computer interfaces in the AR/VR field is evident, as understanding users better can enhance the immersion in virtual worlds.
