Eye gaze collaboration with Brain-Computer Interfaces – using both modalities for more robust interaction

In this chapter, we discuss the motivation for the hybrid Brain-Computer Interface (BCI), and review progress toward more robust user interaction from existing studies. In addition, we discuss the design and development of a hybrid Brain-Computer Interface (hBCI) example that combines two symbiotic modalities: Steady State Visual Evoked Potential and eye gaze technology. By adopting a modular design, we show that it has been possible to implement such hybridisation by integrating mostly existing software components and, indeed, facilitate future updates to the system that will be necessary as hardware, software and interfaces continue to evolve.
