The StimTracker supports high precision time stamps between iMotions’ stimuli presentation and the ABM B-Alert EEG and Tobii TX300 eye tracker.


Some scientific research studies require to determine millisecond response times to stimuli presented within an experiment. The StimTracker from Cedrus allows researchers to eliminate timing delays caused by computer operating systems or monitor graphic cards in data analysis. It uses light sensors to precisely detect stimuli changes and writes this information as time stamps (event markers) in the EEG and eye tracking data. The common time stamps can then be used for easy multichannel synchronization and analysis.
