Peak-end effects in video Quality of Experience
Abstract
The study reported in this paper demonstrated, for the first time, that the peak-end effect, commonly found with respect to memories of experience, also applies to overall Quality of Experience (QoE) measures obtained after participants view a sequence of videos. Sequences of videos shown in an experiment varied according to the sequencing and grouping of videos with better or worse Technical Quality (TQ). An end effect was found for both better TQ and worse TQ videos. However the peak effect was found for bad, but not good, videos. These results provide an important first step towards the development of models of Likelihood to Recommend (L2R) based on accumulated experience with a service.
