BrainSnake: Exploring Mode of Interaction in a Cooperative Multi-brain BCI Game Based on Alpha Activity

摘要

This paper describes the design, development and evaluation of BrainSnake, a cooperative multi-brain closely-coupled brain-computer interface (BCI) game based on alpha activity. BrainSnake uses communication to address common shortcomings of BCI as an interaction modality. A within-subject study was performed to understand the value of communication in a BCI setting by putting players in both a "co-present" and "remote" condition. Results draw a complex picture of player experience but indicate that participants attributed more control over the snake character and less frustration to the co-present condition. Moreover, there was a preference for balancing communication and BCI input while playing the game. Recommendations for future design of cooperative multi-brain BCI games are derived.
