BCI Conference in Graz – September

Paper accepted called: The Impact of Flow in an EEG-based Brain Computer Interface

Official website for Graz 2017 conference.

Major issues in Brain Computer Interfaces (BCIs) include low usability and poor user performance.
This paper tackles them by ensuring the users to be in a state of immersion, control and motivation, called state of flow. Indeed, in various disciplines, being in the state of flow was shown to improve performances and learning. Hence, we intended to draw BCI users in a flow state to improve both their subjective experience and their performances. In a Motor Imagery BCI game, we manipulated flow in two ways: 1) by adapting the task difficulty and 2) by using background music. Results showed that the difficulty adaptation induced a higher flow state, however music had no effect. There was a positive correlation between flow and offline performance, although the flow factors had no effect (adaptation) and negative effect (music) on performance. Overall, favoring the flow state seems a promising approach for enhancing users’ satisfaction, although its complexity requires more thorough investigations.
