BC(eye): Combining eye-gaze input with brain-computer interaction

Abstract

Gaze-based interfaces gained increasing importance in multimodal human-computer interaction research with the improvement of tracking technologies over the last few years. The activation of selected objects in most eye-controlled applications is based on dwell times. This interaction technique can easily lead to errors if the users do not pay very close attention to where they are looking. We developed a multimodal interface involving eye movements to determine the object of interest and a Brain-Computer Interface to simulate the mouse click. Experimental results show, that although a combined BCI/eye-gaze interface is somewhat slower it reliably leads to less errors in comparison to standard dwell time eye-gaze interfaces. © 2009 Springer Berlin Heidelberg.
