Introduction
Brain-Computer Interfaces (BCI) have been shown to be very promising for numerous applications, such as rehabilitation or entertainment, among many others. Despite this potential, most BCI applications remain prototypes that are not used in practice, outside laboratories. The main reason is the widely acknowledged low reliability of current BCI systems that are based on the translation of the spontaneous non-invasive electroencephalogram (EEG): Mental tasks performed by the user are being too often incorrectly recognized by the BCI. Poor recognition performances are due in part to "imperfect" signal processing algorithms used to analyze EEG signals. However, another component in the BCI loop may also be deficient: the signal generator, i.e., the user him/herself who may not be able to reliably produce EEG patterns. Indeed, it is widely acknowledged that BCI use is a skill, which means the user must be properly trained to achieve successful BCI control. If the user cannot correctly perform the desired mental commands, even the most advanced signal processing algorithm could not properly identify them. Despite this, the BCI community has devoted significant research efforts on signal processing, mostly neglecting the human in the loop. For instance, user feedback has been scarcely studied despite various studies which showed promising results with virtual reality and/or multi-sensory stimulations. This workshop aims at addressing this lack of research on training users, by focusing on feedback and training protocols for BCI. More particularly, this workshop aims at 1) convincing the audience that further research on BCI user training is valuable and necessary to push BCI performances to a new level, 2) reviewing current (good) BCI feedback and user training and 3) coming up with new ideas and research directions to advance protocols to teach the BCI skill. Overall, we expect this workshop to be a first step towards exciting new research works and results on user training approaches, with the potential to increase BCI performances and reduce BCI illiteracy.
