Abstract

The ICT industry and services are on the verge of substituting quality of service and utility functions with quality of experience, QoE. While intuitive, QoE, has eluded the research community. QoE takes into account what the user is experiencing with new products and services. Once this information is collected, it becomes an input in the development of the new product or new service. But how does one measure directly quality of experience? In this conceptual paper, I discuss from an ICT perspective, the utility function and quality of service, QoS. I also present how active interested the industry is in QoE. I concluded with some key points that may serve as a guideline in the process of constructing the QoE function.
