Application of Combined Brain Computer Interface and Eye Tracking

As a non-invasive electrophysiological detection technology, electroencephalograph (EEG) is one of the means to diagnose diseases. In addition, EEG is widely used in many fields, such as emotion recognition. Eye tracking technology can record the subjects' saccade, blink, fixation time and pupil changes, which has been applied in the field of psychology. However, there are not many applications about the combination of EEG and eye tracking in recent years. The main purpose of this review is to summarize the application of combined brain computer interface (BCI) and eye tracking. Furthermore, we also discuss the future development of BCI and eye tracking.
