Modeling subjective quality evaluations for mobile video watching in a living lab context

The ability to understand and quantify the Quality of Experience (QoE, i.e., the users´ subjective perception of an application or service) will play a major role in the success of mobile services in the next years. This paper discusses results from an exploratory study in which QoE aspects related to mobile video watching were investigated in a living lab setting. More specifically, we zoom in on usage patterns in a natural research context and on the subjective evaluations regarding different aspects of the mobile video session. Multinomial logistic regression results in a model to estimate the subjective evaluations regarding the perceived distortion and loading speed based on objectively-measured parameters of the video session.
