SMI BeGaze and AcqKnowledge 4.3 – merge physiology and eye tracking data
Starting with AcqKnowledge 4.3 it is possible to synchronize and merge BIOPAC physiological data and SMI BeGaze eye tracking data. Connect the SMI parallel port to BIOPAC isolated digital interface STP100C, then set SMI experiment center to send a trigger with each stimulus presentation, and set AcqKnowledge to record the triggers on a digital channel. When SMI data is imported and merged with an AcqKnowledge file, the trigger data is used to precisely align the data. Using the merged data, it's easy to explore the relationship between a stimulus presentation and the physiological response that follows.
