Attention driven visual QoE: Mechanism and methodologies

User experience plays a crucial role in emerging multimedia services. Traditional Quality of Service (QoS) criteria have been demonstrated to be not adequately accurate to measure and manage the user viewing experience when consuming multimedia content. Recently Quality of Experience (QoE), a quality criterion purely driven by subjective cognition, has been defined to evaluate the overall acceptability of a service. As a perceptual concept, QoE is influenced by internal and external factors. In order to effectively manage visual QoE for multimedia services, visual attention, an integral mechanism of the human perceptual system, should be integrated into QoE definition, assessment, and improvement. This paper systematically presents visual QoE management methodologies driven by attention mechanism.
