Quality of Experience (QoE) relates to how users perceive the quality of an application. To capture such a subjective measure, either by subjective tests or via objective tools, is an art on its own. Given the importance of measuring users’ satisfaction to service providers, research on QoE took flight in recent years. In this paper we present an overview of various techniques for measuring QoE...

Despite the steady increase in home broadband speeds, simple tasks such as watching a video streamed over the Internet or having a Skype call can still be a frustrating experience. Overloaded servers, network congestion, and poor home WiFi quality are just a few of the potential root causes that can hamper users’ Internet Quality of Experience (QoE) [1]. Without the knowledge of where the probl...

Augmented Reality (AR) devices are commonly head-worn to overlay context-dependent information into the field of view of the device operators. One particular scenario is the overlay of still images, either in a traditional fashion, or as spherical, i.e., immersive, content. For both media types, we evaluate the interplay of user ratings as Quality of Experience (QoE) with (i) the non-referentia...

Compared to traditional 2D image techniques, stereoscopic techniques provide additional information the binocular depth, which strongly enhances the immersion. However, it may also cause visual comfort problems because it is still not a perfect representation of natural human vision but to some extent an illusion. How to fairly evaluate and understand the QoE (Quality of Experience) of stereosc...

Apart from user characteristics, properties of the network over which the content is delivered and device on which the content is displayed affect end-user perceived quality. This paper presents a learner quality of experience (QoE) model that apart from the user-related content adaptation, considers delivery performance-based content personalisation in order to improve user experience when int...

Quality of experience (QoE) takes a user-focused view of the Internet experience, derived from lower-layer metrics like quality of service, reliability and usability, measuring ”the difference between what a customer expected, and what they actually received.” (FY/c) QoE can be usefully divided into a micro and macro aspect, covering the individualized and often shortterm experience of an indiv...

Describing service quality from the end-users' point of view is fulfilled by using Quality of Experience (QoE) metrics. In a networking environment QoE metrics are very close to Quality of Service (QoS), but – because of the subjective nature of QoE – they could not be derived directly from QoS. Collection and analysis of QoS and SLS (Service Level Specification) properties of networking servic...

Web service composition enables seamless and dynamic integration of Web services. The behavior of participant Web services determines the overall performance of a composition. Therefore, it is important to choose high quality services for service composition. Existing Web service selection and discovery approaches rely on non-functional aspects (also known as quality of service or QoS) e.g., re...
