Quality of Experience

Quality of Experience (QoE) is the degree of delight or annoyance of the user of an application or service. It results from the fulfillment of his or her expectations with respect to the utility and / or enjoyment of the application or service in the light of the user’s personality and current state [16]. Thus, QoE ties together user perception, experience and expectations to application and network performance, typically expressed by QoS parameters. Quantitative relationships between QoE and QoS are required in order to be able to build effective QoE control mechanisms onto measurable QoS parameters. Generic relationships between QoE and its influence factors provide fundamental insights into the nature of user perception and are the basis for quantified QoE models of concrete Internet applications. The developed QoE provisioning-delivery hysteresis [9], the IQX hypothesis [4], the WQL hypothesis[2], and the SOS hypothesis [12] are highly relevant for application and network research as well as the human computer interaction (HCI) research community. The results were also discussed with psychologists at the Internet Research Center at the University of Würzburg and will be presented in the following.
