Abstract
The integration of a P300-based brain–computer interface (BCI) into virtual reality (VR) environments is promising for the video games industry. However, it faces several limitations, mainly due to hardware constraints and constraints engendered by the stimulation needed by the BCI. The main limitation is still the low transfer rate that can be achieved by current BCI technology. The goal of this paper is to review current limitations and to provide application creators with design recommendations in order to overcome them. We also overview current VR and BCI commercial products in relation to the design of video games. An essential recommendation is to use the BCI only for non-complex and non-critical tasks in the game. Also, the BCI should be used to control actions that are naturally integrated into the virtual world. Finally, adventure and simulation games, especially if cooperative (multi-user) appear the best candidates for designing an effective VR game enriched by BCI technology.
Highlights
A video game can be defined as “a mental contest, played with a computer according to certain rules, for amusement, recreation, or winning a stake”
We suggest restricting the use of the brain–computer interface (BCI) to a limited set of aspects (LoE C; Level of Interest (LoI) 1)
We suggest the use of the same workaround as for strategy games and to use a thirdAdventure games are well-suited for P300-based BCI, if the player is given a set of limited options person point of view (LoE C; LoI 1)
Summary
A video game can be defined as “a mental contest, played with a computer according to certain rules, for amusement, recreation, or winning a stake”. It has been defined briefly as “story, art, and software” [1]. By completely different means, virtual reality (VR) and the brain–computer interface (BCI) are both excellent candidates for enhancing the possibilities of entertainment and satisfaction in video games. Both enhance immersion and it is a common belief that this encourages the feeling of amusement.
