Computational NeuroscienceA brain computer interface-based explorer

- We propose a file explorer based on a BCI mouse.
- Common functions of an explorer have been implemented in the BCI system.
- Experimental results prove the feasibility of the system.

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