Towards in SSVEP-BCI systems for assistance in decision-making

Abstract

In recent years, Brain Computer-Interfaces (BCI) has a major focus on systems out of clinical scope. These systems have been used to control electrical and electronic equipment, control of digital games and other kinds of “control”. Such control can be accomplished through decision-making by a BCI system. A paradigm known for this purpose is SSVEP (system based on steady-state visually evoked potential paradigm), in which it is possible to distinguish targets with different frequency flicker through visual evocations. This paper proposes a human-computer interaction system using SSVEP for assistance in decision-making. In particular, the work describes a prototype of traffic lights proposed as a case study. The experiments with this prototype, have created decision-making situations, allowing the SSVEP-BCI system assists the individual to decide correctly.
