International Collaborations in Brain-Computer Interface (BCI) Research

The strength and quality of a research field can be depicted from its literature. In this paper, the Brain-Computer Interface (BCI) research literature is examined for collaborations at the individual level (i.e. researchers) and international level (i.e. countries). Records from the Web of Science (WoS)(Thomson Reuters) are examined to form an updated picture of the BCI research worldwide and in particular its international collaboration. Results indicate strong collaboration between Germany, USA, Austria, and Italy. At the BCI researcher level, this is less prominent. Furthermore, a research quality proxy, based on both Impact Factor (IF) and Eigen Factor (EF), is also examined for journals publishing BCI research. These results, updated regularly, will be published online to help to improve the BCI research community visibility.
