This paper presents an emerging research area of using eye response for video quality evaluation. Experiments were conducted to study how eye movements such as saccades and fixations in a video, which represents visual information processing, react to changes in video quality. Discussed in this paper are two sets of experiments on eye movements. The first experiment had multiple original movie video clips with quality variation applied across the entire scene. The second round of tests had multiple original movie video clips with transitioning between extreme qualities half way through within the video. The key contributions of this paper are an exploration of gaze response to video quality variation and results of the experiment show a significant difference in Fixations/Saccades ratio between low and high-quality videos. Gaze response to video quality shows a potential to be considered as one of the quality evaluation metrics for future studies.
