Abstract

A BCI (Brain-Computer Interface) is based on the analysis of the brain activity recorded during certain mental activities, to control an external device. Some of these systems are based on discrimination of different mental tasks, matching the number of mental tasks to the number of control commands and providing the users with one to three commands. The main objective of this paper is to introduce the navigation paradigm proposed by the University of Málaga (UMA-BCI) which, using only two mental states, offers the user several navigation commands to be used to control a virtual wheelchair in a virtual environment (VE). In the same way, this paradigm should be used to provide different control commands to interact with videogames. In order to control the new paradigm, subjects are submitted in a progressive training based in different VEs and games. Encouraging results supported by several experiments show the usability of the paradigm.
