What is eye-tracking and how does it work

Eye-tracking is a state of the art process which tracks users' eye movements. In other words, it's a process of measuring eyes position over time, so measuring where someone was looking (where was his/her gaze point) and for how long. A device that makes those measurements is called an eye-tracker. (...)

RealEye 7.3 - Finish test with a keystroke

We're happy to announce that we've just released RealEye v7.3, which contains a pretty commonly asked feature: the ability to finish displaying stimuli (image/video) on a keystroke event.

This ability will enable researchers to create implicit reaction tests like IAT or IRT and measure not only which keys were pressed but also what was the reaction time was and the average reaction time for each key separately.

Please read more about this recent feature in our Support

Special thanks to Pablo for requesting this feature long time ago, it's finally out there! :)

RealEye 7.2 - Less eye-tracking data gaps and better sampling rate on low-end hardware

RealEye v7.2 release focused mainly on ensuring more useful data.
This time we've tackled two things:

  • Reduce eye-tracking data gaps when the participant moves head too much.
    SOLVED: The eye-tracking test is paused when the "fix your position" popup is displayed.
  • Increase eye-tracking sampling rate for low-end/old hardware that does not support WebGL (GPU acceleration).
    SOLVED: We're now using the latest browser features that should result in up to a 40% higher eye-tracking sampling rate.

Other essential updates in version 7.2:

  • We've enabled the ability to export Facial Coding data into CSV (Facial Coding is still in BETA).
  • The price for a University license changed to $350/month. If you have active University license - those changes won't affect your account.
  • Exports are re-ordered into several categories.
  • Drop-rate info for the last 30 and 7 days.

  • Facial coding offers "Neutral" and "Happy" stats.
  • French instructions for participants.
  • Unused participant spots get released when a study is removed.
  • Participant Quality Stats page can show recording and heatmaps.
  • University PRO license is available.
  • Drop-rate CSV.
  • CSV filename with Study/Item name.
  • Improve tester logs - page opened.
  • Optimize Heatmap playback.
  • Speed up gaze data download (use cache) and reduce CSV export time.
  • Speed up AOI Overall Stats computation.

  • Other UI/UX tweaks, performance improvements, and bug fixes.


RealEye 7.0 - Eye-tracking Metrics Improved

RealEye version 7.0 introduces quite significant improvements in eye-tracking metrics we provide on the dashboard and in the exported CSV files.

NOTICE: Some metric values might have changed from what you've seen in previous versions of RealEye. That's because we've improved our algorithms to provide even more accurate and useful data.

If you have any questions regarding this release please, contact us via email or chat. We'll be happy to answer all your questions.

A detailed explanation of the eye-tracking metrics you can get from RealEye is described on this support page.

RealEye 7.0 release notes:

  • Improved eye-tracking metrics, e.g.:
    • Show AOI size in percentage of the whole stimuli.
    • Show AOI time range.
    • A new metric: "Gaze count".
    • A new metric: "First Fixation Duration".
    • Fixation is considered valid for the AOI time range:
      - if it has begun exactly when the AOI time range starts or later
      - if it has begun before the end of theAOI time range
    • Fixation point is an average of all included gaze points.
    • For smoothed and normalized data gaze (fixations), raw gaze timestamp is now considered to be gaze end time.
    • "Revisits" metric improved.
      AOI visit is detected:
      - if there's a fixation in the AOI, or many fixations "one after another".
  • The readability note removed - it was too subjective.
  • Data export improved: CSV files with AOI data take the AOI time range into account.
  • You can manually adjust the "Noise reduction" setting both for fixations and gazes.
  • New data export file: CSV with AOI Overall Stats. It's a file that contains most of the metrics you see on the dashboard.
  • New data export file: CSV Raw Gazes Denoised.
  • Improved Data Chart.
  • Minor UI/UX and performance improvements. Bug fixes.
  • Security and reliability improvements.

Special thanks to Luis, one of our customers, who has given us a lot of feedback regarding our metrics and data export feature.
