The importance of task completion times for modeling web-QoE of consecutive web page requests

In the context of Quality of Experience for web browsing, recent results have shown that existing models for measuring performance in terms of QoE still address a too limited selection of metrics. For a more valid approach, an extension of single page requests into 'sessions', i.e. a consecutive series of page requests, and task-driven evaluation is required. In our study, we evaluated the impact of page load durations, total session durations and task completion times on Web-QoE. The results show that task completion time is a key influencing factor for understanding Web-QoE of sessions. Thus, novel diagnostic information beyond page load durations is needed to reliably capture the interactive nature of web applications when measuring Web-QoE.
