Subjective assessment methodology for preference of experience in 3DTV

The measurement of the Quality of Experience (QoE) in 3DTV recently became an important research topic as it relates to the development of the 3D industry. Pair comparison is a reliable method as it is easier for the observers to provide their preference on a pair rather than give an absolute scale value to a stimulus. The QoE measured by pair comparison is thus called “Preference of Experience (PoE)”. In this paper, we introduce some efficient designs for pair comparison which can reduce the number of comparisons. The constraints of the presentation order of the stimuli in pair comparison test are listed. Finally, some analysis methods for pair comparison data are provided accompanied with some examples from the studies of the measurement of PoE.
