ABSTRACT
In this chapter, several decoding methods for the Steady State Visual Evoked Potential (SSVEP) paradigm are discussed, as well as their use in Brain Computer Interfaces (BCIs). The chapter starts with the concept of BCI, the different categories and their relevance for speech- and motor disabled patients. The SSVEP paradigm is explained in detail. The discussed processing and decoding methods employ either time-domain or spectral domain features. Finally, to show the usability of these methods and of SSVEP-based BCIs in general, three applications are described: a spelling system, the “Maze” game and the “Tower Defense” game. We conclude the chapter by addressing some challenges for future research.
