Visualizing, describing and reviewing BCIs' workflow from data: what's needed?
Brain-Computer Interfaces is a technology aiming at enhancing communication capabilities and improving human interactions with the environment. In recent years, there have been tremendous impulses in research and development, and several resources have been released to the community, supporting different data formats, methods, and models. This heterogeneity is mainly a consequence of the multidisciplinarity of the research field, which brings to describe the same system from different points of view. Then, easy accessibility to BCI data and tools remains challenging because of the lack of well-defined standards. In fact, while there exist various approaches to defining standards or unified frameworks, the applicability scope is constrained to a merely conceptual analysis if the appropriate tools are not provided. In this work, we discuss how BCI's workflow should be visualized, described, and reviewed by considering the intersection between the BCI glossary, the BCI functional model, and the databases that the IEEE Standard Association P2731 Working Group has been developing. Our goal is to implement a visual interactive tool to describe the interoperability between these three abstractions. We picture a user-friendly tool able to generate a visual report after reading the necessary information from a BCI data file and provide hyperlinks to the BCI glossary for all the used terms. This could potentially enhance the synthesis and simulation of multiparadigm BCI models by improving the experience of any BCI developer, researcher, or user, in the assessment and construction of such systems and facilitate the adoption of standards. A discussion with all stakeholders is then necessary to maximize the utility of such a visual tool.
