Abstract:As the scope of the brain-computer interface (BCI) applications is extending from medical to recreational use, the expectations of BCIs are also changing. Although the performance of BCIs is still important, finding suitable BCI modalities and investigating their in uence on user experience demand more and more attention. As BCIs have widely been used in medical applications, to facilitate making selections, it would be imaginable to apply similar BCIs to recreational applications. However, whether they are suitable for recreational applications is unclear as they have rarely been evaluated for user experience. In this study two BCI selection methods and a comparable non-BCI selection method were integrated into a computer game to evaluate user experience in terms of immersion and affect. The BCI selection methods were based on the P300 and steady-state visually evoked potential (SSVEP) paradigms. An experiment with fourteen participants showed that the SSVEP selection method was capable of enriching the user experience in terms of immersion and affect. Participants were significantly more immersed and the SSVEP selection method was found more positively affective. Although it was expected that P300 would enrich user experience, it did not.
