Accuracy Threshold

Accuracy threshold defines the accuracy that participants must achieve when performing their session. The accuracy is calculated at the end of the calibration step. Participants will see a circle getting smaller over 10 seconds at the end of the calibration. The average value from the gaze points collected during this period to the center of the screen, corresponds to the accuracy value. If the accuracy value is below the accuracy threshold, the participant can continue with their session. Otherwise, the participant receives a notification to repeat the calibration under better conditions. This ensures a certain quality of the collected data.

Calibration

Just like eyetracking hardware in the lab, Adsata's eyetracking software needs to be calibrated. Calibration means that coordinates on the screen are assigned to specific positions of the participant's eyes. Therefore, the participant has to click on a circle with the mouse while looking at it. Adsata's eyetracking software is thus trained to later infer where the participant is looking from the positions of his/her eyes.

Participant feedback

Adsata collects feedback from your participants in order to improve their experience. Tthe participants will have the possibility to give us feedback after doing an eyetracking session.
