Powerful software

for powerful research

To analyze the eye tracking data you’ve gathered from eye tracking glasses like the Tobii Pro Glasses 3, you’ll need software that can provide the precision and accuracy your study requires. With the iMotions Eye Tracking Glasses Module, you can analyze your real-world eye tracking data with metrics such as:

  • Heatmaps
  • Gaze replays
  • Areas of interest (AOI)
  • Time to first fixation
  • Automated gaze-mapping: converts gaze from dynamic environments into static scenes for simpler aggregation and analysis
