Correlation between peak velocity of saccades and susceptibility to motion blur

Abstract

If participants are not carefully selected for subjective evaluations of TV picture quality, the evaluations tend to be imprecise and to lose power to detect statistically significant differences between experimental conditions. In assessments of traditional television, participants' visual acuity (VA) should be screened. For emerging TV systems with a wide field of view (FOV), in which objects move quickly relative to the display frame, it is unclear whether screening viewers' VA is sufficient or not. Here, we evaluated saccadic eye movement parameters to identify adequate methods to screen participants. We found that the peak saccade velocity can be used to screen participants for wide-FOV TV motion picture evaluation studies, because of the significant correlation between the average subjective evaluation score and the peak saccade velocity.
