Enhancing In-game Immersion Using BCI-controlled Mechanics

Abstract

Due to multimodal approach, the virtual reality experiences become increasingly more immersive and entertaining. New control modalities, such as brain-computer interfaces (BCIs), enable the players to engage in the game with both their bodies and minds. In our work, we investigate the influence of employing BCI-driven mechanics on player’s in-game immersion. We designed and implemented an escape room-themed game which employed player’s mental states of focus and relaxation as input for selected game mechanisms. Through a between-subject user study, we found that controlling the game with mental states enhances the in-game immersion and attracts the player’s engagement. At the same time, using BCIs did not impose additional cognitive workload. Our work contributes qualitative insights on psychocognitive effects of using BCIs in gaming and describing immersive gaming experiences.
