I have heard people suggesting me to track the dominant eye when doing single eye eye-tracking, because the "dominant eye will give more accurate data". However in normal subjects the fixation locations of two eyes should be quite consistent. Is the data quality significantly different between dominant eye-tracking and non-dominant eye-tracking?
Hi there, It depends on what level of precision you want. I would say yes to tracking the dominant eye. I recently carried out a study where the dominant eye was closer to to target and more often on the target compared to the non-dominant eye. However, if you are recording targets bigger than 0.5 degrees of visual angle, then it is not a problem.
No, unfortunately. I am still working on it. However, take a look at the study attached. In the opposite way, they consider a fixation accurate where the dominant eye is located on the target. Also, what eye tracker are you using? I am using the tobii x3-120 and in their manual they recommend using the dominant eye for more accurate precision. I am finding in my study the dominant eye is more accurate too.
