The iMotions Eye Tracking Glasses Module

Main features

With the iMotions Eye Tracking Glasses Module, you can collect and analyze real-world eye tracking data using world-leading, research-grade glasses from Tobii, Pupil Labs, Argus Science, and SMI. The Module allows for advanced analysis using tools such as heatmaps, gaze replays, and areas of interest (AOI) output metrics like time to first fixation & time spent. iMotions also provides automated gaze-mapping technology, in which gaze from dynamic environments is converted to static scenes for simpler aggregation and analysis.
