Evaluate effects of multiple users in collaborative Brain-Computer Interfaces: A SSVEP study

This study investigates the effects of collaboration on task performance in brain-computer interface (BCI) based on steady-state visually evoked potential (SSVEP). Navigation tasks were performed in a virtual environment under two conditions, e.g., individual performance and team performance. The results showed that average task completion time in the collaborative condition is decreased by 6 percent compared with that of individual performance, which is inline with other studies in collaborative BCI (cBCI) and joint decision-making. Our work is a step forward for the progress in BCI studies that include multi-user interactions. ### Competing Interest Statement The authors have declared no competing interest.
