Situation and progress of brain computer interfaces in China-a bibliometric analysis of the literature from China national knowledge infrastructure database / 中华物理医学与康复杂志

ABSTRACT

Objective To investigate the situation and progress in technology of brain computer interfaces (BCI) by using the bibliometric approach.Methods Literature searching was done in China national knowledge infrastructure (CNKI) database using keyword brain computer interface.Subsequent results were analyzed by using softwares concerning the periodical distribution,subjects' distribution,foundations,authors,institutes,journal types and key words.Results Overall 425 publications from 160 journals were included.The amount of the relevant articles showed an increasing trend in 2002 to 2012.The research in BCI in China was supported by a large amount of funds.There were a lot of Chinese authors and institutions participating in BCI study,and they were widely distributed across the country.However,only 32.56％ of all authors and 51.85％ of all institutions published more than 1 article.Moreover,research on BCI mainly was focused on the biomedical engineering aspect.Conclusions Research on BCI developed rapidly in the past 12 years in China and will continue to develop in the following decades.In the future studies,the focus should shift to clinical research instead of biomedical engineering,and to make this technology a useful clinical practice is the first priority.
