Calibrate eye tracker

Aim

To calibrate an eye tracker device to ensure recordings are as accurate as possible.

Before you begin

  • The calibrate functionality depends on your application-level user role:
    • As an Administrator you can calibrate eye trackers for any project.
    • As a Researcher you can calibrate eye trackers for projects you created yourself and projects shared with you as a member.
    • As a User you can calibrate eye trackers for projects shared with you as a member.
  • Ask a colleague or co-worker to assist you as a participant because calibration is an interplay between a Test leader PC and the Participant PC.
  • Navigate to the record page of the test station inside your project for which you want to calibrate the eye tracker.

Note

  • Calibration starts from the Test leader PC. 
  • Each procedure step indicates who, you or the participant, must execute the step.
  • Check the Frequently Asked Questions (FAQ), if you run into trouble.

Procedure

  1. You: Ask the participant to take place at the Participant PC and to follow the instructions on the screen.
