Quality of Experience

In Quality of Experience (QoE) we want to understand how the quality of a system or service affects the experience of users. When does a long delay in tele-communication disrupt the conversation and when do we not even notice at all? How much bandwidth does a videostream need that we really feel we are getting a better quality? It turns out, to understand the experience of users, taking personal and situational factors into account is as important as the actual quality of the system. Media consumption has become a ubiquitous part of life and if we want to optimize our systems understanding the interplay of situation, personality and system quality is a key requirement.
