Quality of Recordings

[Elizabeth]

I am working on statistical analysis of the data provided by my Tobii eye tracking recordings. I am trying to find an acceptable recording quality “cut-off” value, but there is nothing standard in the literature. Is there a recommended acceptable quality of recording?

There is an “Accuracy and precision test method for remote eye trackers”. This paper describes the comprehensive method for gaze accuracy and precision measurements that Tobii has adopted to facilitate performance comparisons of different remote eye tracking systems. This analysis is done offline, after the test.
