Query: Towards Artificial Learning Companions for Mental Imagery-based
  Brain-Computer Interfaces   Mental Imagery based Brain-Computer Interfaces (MI-BCI) enable their users to
control an interface, e.g., a prosthesis, by performing mental imagery tasks
only, such as imagining a right arm movement while their brain activity is
measured and processed by the system. Designing and using a BCI requires users
to learn how to produce different and stable patterns of brain activity for
each of the mental imagery tasks. However, current training protocols do not
enable every user to acquire the skills required to use BCIs. These training
protocols are most likely one of the main reasons why BCIs remain not reliable
enough for wider applications outside research laboratories. Learning
companions have been shown to improve training in different disciplines, but
they have barely been explored for BCIs so far. This article aims at
investigating the potential benefits learning companions could bring to BCI
training by improving the feedback, i.e., the information provided to the user,
which is primordial to the learning process and yet have proven both
theoretically and practically inadequate in BCI. This paper first presents the
potentials of BCI and the limitations of current training approaches. Then, it
reviews both the BCI and learning companion literature regarding three main
characteristics of feedback: its appearance, its social and emotional
components and its cognitive component. From these considerations, this paper
draws some guidelines, identify open challenges and suggests potential
solutions to design and use learning companions for BCIs.
