Eye-Tracker Analysis of the Contrast Sensitivity of Anomalous and Normal Trichromats: A Loglinear Examination with Landolt-C Figures

The contrast sensitivity of normal and anomalous trichromats were examined with Landolt-C figures by eye-tracking system. For the measurements, two series test images (achromatic colored) designed. difficulty levels tests gradually increased after each right answer. In case observation ring figures, variables related to fixation duration, count, visit duration count significantly affected this subject, success or image parameters, their interactions. main questions study as follows: Which statistical method is suitable model differences between trichromats? eye-movement have a significant effect on investigated parameters interactions? Is there any difference How does survival time change in achromatic colored figures? results showed that answers can be described multiple cross-classified contingency tables evaluated effectively loglinear regression. analysis are more successful interpreting images, while seemed efficient perceiving images.
