Abstract:	Evaluating user experience (UX) with respect to previous experiences can provide insight into whether a product can positively aect a user's opinion about a technology. If it can, then we can say that the product provides a positive UX. In this paper we propose a method to assess the UX in BCI systems with respect to user expectations. We demonstrate the application of our method in a preliminary study. The study results showed that BCI game control was natural and enjoyable despite the low reliability of the BCI. However SSVEP based selection induced fatigue on participants. The proposed method can extract the right and wrong practices to employ BCI in applications and can suggest interaction paradigms or considerations to follow when developing BCI systems.
