Quality and Usability

Cross-service, cross-user Quality of Experience (CSCU-QoE)

The internet can be used to implement new services and to provide established services at lower costs. Due to the design of the internet the parameters of an end-to-end connection cannot be guaranteed, which results in different levels of service quality.

The aim of this project is to study the long-term Quality of Experience (QoE) of IP-based communication and entertainment services. The key question is how the user’s QoE evolves over time and how this knowledge can be used to determine Key Quality Impact (KQI) factors. Starting with the development of a Web browsing-QoE (Web-QoE) model and the adaptation of existing IP-based QoE models, the project will eventually focus on developing cross-service QoE models for IP-based services. In the scope of this project services such as  Voice-over-IP (VoIP), video telephony, Video on demand (VoD), IPTV, and web browsing.
