Abstract: This paper describes a flexible method for synchronizing electroencephalography (EEG) and eye tracking (ET) recordings to the presentation of visual stimuli. The method consists of embedding a synchronization signal in the visual stimuli, and recording this signal with both the EEG and ET equipment. The signal is recorded by the EEG device as an additional data channel, and with the camera used in the ET equipment by modulating the global illumination of the scene in time with the synchronizing signal. The prototype system where this method was implemented resulted in a single sample of jitter in both the EEG and ET system, while the ET system achieved a spatial resolution of 1.26 degrees. The system will be used in future work with augmented memory applications.
