Abstract
Experiments were conducted to examine whether information refresh rate and moving objects have an effect on saccade latency times. The ratio of the number of moving objects to the number of static objects in a display was used to define dynamic object ratio (DOR), an independent variable in the study. The results of the experiment reveal the following: (a) dynamicity and information refresh rates have effects on saccade latency; (b) it was observed that when DOR increases, participants took longer time to make their initial saccades; and (c) as the DOR increases beyond 2 dynamic objects, latency times seem to be the same irrespective of the information refresh rate. The results suggest that the movement of objects and the information presentation refresh rates in a display environment are important variables to consider in visual cognition studies. We hope to expand the experiment to include effects on visuospatial attention, information recall, and information contents to be analyzed by human participants.
