ABSTRACT
This chapter provides an overview of audiovisual quality perception and how evaluation approaches of quantitative and sensory evaluation help to better understand audioviinteraction. It discusses an assessing audiovisual quality and studying audiovisual interaction by applying sensory evaluation. The chapter introduces open profiling of quality as a structured approach to study audiovisual quality. In conventional audiovisual quality research, a focus is set mainly on understanding user preference toward technical settings of system components and expressing the outcome of any quality assessment as an affective degree-of-liking using so-called mean opinion scores. The H. McGurk effect is a well-known example of audiovisual interaction in which auditory and visual information is integrated into a new and unified audiovisual perception. The work on audiovisual quality evaluation has recently been conducted mainly in the domain of quality of experience. The descriptive sorted napping study was conducted at the end of a series of research into audiovisual quality perception.
