User-centric quality of experience measurement

Abstract

Quality-of-experience (QoE) produces the blue print of human perception, feelings, needs and intentions, while Quality-of-Service (QoS) is a technology centric metric used to assess the performance of a multimedia services and/or network..It is quite important for service/content providers tounderstand user/customer experience requirements in order to improve theservice quality or the content recommendation. With advent of 3G and 4G wireless networks, and efficient smart phones, the band-width hungry multimedia applications are becoming common in use on end-user devices. Thus,it is also important for telecom operators to understand the impact of wireless network performances on the user experience in mobile environment.On the fly evaluation of user experience for multimedia services is a challenging problem especially in mobile environments. It implies the collection and the correlation of a mixture of variables on network conditions, on the service, as well as on the user itself. This paper proposes an innovative mobile application that can be used for measuring user quality-of-experience on the fly with a high accuracy and the consideration of multiple parameters about the user, the network and the system. This application takes advantages ofcurrent advances in mobile technologies to measure user experience directly on the user device. In addition, it aims to preserve the user privacy by transmitting only estimated quality-of-experience to the service provider.
