Abstract :
Monitoring eye movement offers insights into visual perception, as well as the users associated attention mechanisms and cognitive processes. The paper presents the results of an empirical study that investigated the impact of differing multimedia presentation frame rates on the user´s perceptual experience, as reflected through video eye path data. Results show that varying frame rates do not affect the median coordinate value of user eye gaze and therefore highlight that selection of visual cues, which defines a user´s region of interest, is not adversely affected by frame rate variation.
