• If the background color of the Calibration Result is light yellow, you have
achieved a medium quality calibration. You might be able achieve better eye
tracking results by improving one or more points individually.
• If the background color of the Calibration Result is green, you have achieved a
high quality calibration.
The closer the lines within the calibration point are to a dot in the center of the circle
of the calibration point, the better the calibration is of that point, .You can choose
the points to be improved and calibrate only those points again.
Improve one or more calibration points by:
1. Under
Calibration Result
marking the point(s) you want to improve.
2. Clicking
Improve Point(s)
and a calibration for the selected point(s) will
start.
The quality of the calibration can depend on several different things. If the background
color is red and the lines are long, it can indicate that there is something wrong with
the setup, e.g. that the Display Area measurements were faulty. Other things that can
influence the calibration results are scratches or smudges on glasses or interferences
from surrounding light sources. By cleaning the glasses or ensuring that the eye
tracker or the person in front of the eye tracker is not facing a light source that emits
near infrared light (e.g. the sun) the calibration results can often be improved.
Be aware that no matter what quality of calibration you have achieved you will be
able to select OK or Apply and begin using the eye tracker. It is the accuracy and
functionality of the eye tracker that is affected by the quality of the calibration results.
Try for the best calibration possible before proceeding.
Select Finish on the final page of the Configuration Guide and your settings and
configurations will be saved for future use.
