A Triple User Characterization Model for Video Adaptation and Quality of Experience Evaluatio

This paper proposes the triple sensation-perception-emotion user characterization model for content adaptation and discusses adaptation tools and quality of experience metrics in light of this model. In the context of this paper, the utility would be associated to the sensorial, perceptual and emotional dimensions of the quality of experience. The adequate usage by the adaptation mechanism of available user preferences data will imply higher quality perceptual and emotional experiences. The major purpose of this paper is to launch some new ideas in the field of video adaptation and quality of experience evaluation. This model is hierarchical in the sense that typically emotions build on perceptions and perceptions build on sensations, setting a hierarchy
