Multi-Brain BCI Games: Where to Go from Here?

Clinical research on brain-computer interaction has focused on patients and assistive technology for disabled users. How can we provide an ALS patient with the possibility to communicate with the outside world using his or her brains only? Or, how can an artificial limb or prosthetic device be controlled by thoughts only. In the early years of brain-computer interface research many other applications were considered. Artists used EEG devices to audify and visualize brain activity and gave it a role in real-time performances. Rather than having just one person’s brain activity measured and used they also thought of, designed, and implemented artistic applications where brain activity of two users was needed in order to produce a desired result. In this paper we look at various artistic and other non-clinical BCI applications that can become the face of BCI research in the near future.
