The iMotions VR Module

Main features

The iMotions VR Eye Tracking Module allows for eye tracking data collection, visualization, and analysis in virtual environments using the Tobii HTC Vive VR and Varjo VR-1 eye tracking headsets. Capture and analyze visual attention using heatmaps, gaze replays, and areas of interest (AOI) output metrics such as 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.
