Evaluating and Reporting Data Quality in Eye Movement Research. Technical Report No. 193.
McConkie, George W.
Stressing that it is necessary to have information about the quality of eye movement data in order to judge the degree of confidence one should have in the results of an experiment using eye movement records as data, this report suggests ways for assessing and reporting such information. Specifically, the report deals with three areas: (1) characteristics of the eye movement signal, (2) algorithms used in reducing the data, and (3) accuracy of the eye position data. The paper argues that all studies involving eye movements data should report such information. Appendixes include linear interpolation algorithms for mapping the eye movement signal to stimulus space, and a way of obtaining an index of accuracy for each data point. (Author/FL)
