What is calibration?
For eye tracking to accurately track eye movements, the algorithm must be calibrated to each participant. To do so, the participants are taken through one or multiple calibrations within a study. During a calibration, the participant is asked to look at specific points on the screen, also known as calibration dots, while the eye tracking algorithm measures characteristics of the participant’s eyes. This information is then used to calculate the gaze data.
Why is this important?
Calibrations are vital to ensure accuracy of the data collected. Excessive movement and other participant behaviors jeopardize the usability of their sessions; by having calibrations strategically implemented throughout the study, the health of a session can be maintained in spite of common participant aberrations.
Calibration Check Points (CCPs)
Based on years of data collected, Sticky's platform is able to automatically identify and insert CCPs where they are most likely to improve session usability and prevent participant errors from negatively impacting the session. To do so, the platform uses several factors including study length and design.
At least 1 CCP must be enabled for a study to be launched;
A CCP will be added to a study for every 60 seconds of consecutive media;
It is recommended that you keep all CCPs enabled. Turning CCPs off may lower the study's overall success rate;
CCPs cannot be moved, they are strategically placed to optimize session performance;
If there are instructions immediately preceding media, a CCP will be placed before the instructions to prevent participants from forgetting instructions if the calibration were to come after;
If there are survey questions immediately preceding media, a CCP will be placed immediately after the questions.
