Customized Timing for Experimental Psychologists and Neuroscientists

The StimTracker for SMI by Cedrus Corporation is a customized timing and synchronization solution for multimodal scientific research with SMI Eye Trackers. StimTracker for SMI allows experimental psychologists to determine accurate participant response times by precisely marking the onset of visual or sound stimuli.

The device also sets common time stamps with complementary physiological devices which makes it a perfect multichannel synchronization tool for neuroscientists. StimTracker for SMI is a scientific solution for SMI eye trackers allowing accurate timing analysis in the millisecond precision range for up to eight data channels simultaneously.

Compatibility with SMI Eye Tracking Solutions

StimTracker for SMI is compatible with SMI’s mobile (SMI Eye Tracking Glasses), Remote (SMI iView 2K, RED250mobile, REDn Scientific, RED250/500) and Hi-Speed eye tracking systems.

It is a plug & play device which can be ordered directly through Cedrus corporation.

Determine millisecond response times

Some scientific research paradigms require to determine millisecond response times to stimuli presented within an experiment. The StimTracker for SMI helps researchers to eliminate timing delays caused by computer operating systems or monitor graphic cards in data analysis.

The StimTracker for SMI uses light sensors to precisely detect stimuli changes and writes this information as event markers in the eye tracking data file.

Multisignal integration and synchronization

For studies which require multisignal data integration and synchronization, StimTracker for SMI can receive signals in parallel from a stimulus presentation software (E-Prime, Superlab etc.), a microphone, two audio channels, and a participant response key.

StimTracker for SMI sets markers for these incoming signals and can send those markers simultaneously to the SMI eye tracking system and to an external physiological device such as EEG systems. The common time stamps in both data files can then be used for easy multichannel synchronization and analysis.
