OneClick: A Framework for Measuring Network Quality of Experience

Abstract

Abstract-As the service requirements of network applications shift from high throughput to high media quality, interactivity, and responsiveness, the definition of QoE (Quality of Experience) has become multidimensional. Although it may not be difficult to measure individual dimensions of the QoE, how to capture users' overall perceptions when they are using network applications remains an open question.In this paper, we propose a framework called OneClick to capture users' perceptions when they are using network applications. The framework only requires a subject to click a dedicated key whenever he/she feels dissatisfied with the quality of the application in use. OneClick is particularly effective because it is intuitive, lightweight, efficient, time-aware, and application-independent. We use two objective quality assessment methods, PESQ and VQM, to validate OneClick's ability to evaluate the quality of audio and video clips. To demonstrate the proposed framework's efficiency and effectiveness in assessing user experiences, we implement it on two applications, one for instant messaging applications, and the other for firstperson shooter games. A Flash implementation of the proposed framework is also presented.

A real-time video quality estimator for emerging wireless multimedia systems

“…The MOS rates the video quality on a scale of 1-5, where 5 is the best possible score. It should be noted that in the tests, observers tend to avoid scores at the extreme end of the scale (1 or 5) due to the influence of psychological factors [21]. However, MOS is not suitable for real-time video assessment approaches.…”

Quality-of-Experience (QoE) in Emerging Mobile Social Networks

“…The service providers have to more carefully observe users' perception and tune QoS parameters according to the observation. To deal with this issue, accurate assessment of QoE has been studied in early projects in wired networks [13], [14], [23], [24]. Specially, Chen et al [23], [24] proposed a framework to capture users' perception when they are actually using network applications.…”

Review and Analysis of Cloud Computing Quality of Experience

“…Chen et al [5] argue that obtaining user feedback after they used an application is not the most appropriate mechanism. They proposed a QoE capture framework called OneClick where users click a particular button indicating they are not satisfied with the quality of an application.…”
