Explorer based on brain computer interface

摘要

In recent years, various applications which apply the hybrid brain computer interfaces (BCIs) have been studied. In this paper, we present a hybrid BCI system to operate the explorer with P300 and motor imagery, which is mainly composed of a BCI mouse, a BCI speller and an explorer. Through this system, the user can access to his computer and manipulate (open, close, copy, paste, delete) files such as documents, pictures, music, movies and so on. The system has been tested with 5 subjects, and the experimental results show that the explorer can be successfully operated according to subjects' intention with only a small number of mistakes.
