Individualized Quality of Experience Estimation in Audiovisual Communication

The book presents an in-depth exploration of the Individuality Assisted Estimation (IAE) model in the context of Quality of Experience (QoE) assessment for multimedia, specifically audiovisual communication. The book delves into how individual characteristics, including psychological traits and states, influence perceptions of multimedia quality. The book argues for the integration of individual differences into these assessments, hypothesizing that this approach can enhance the accuracy and relevance of QoE ratings. Through a series of experiments and analyses, the book rigorously evaluates the effectiveness of the IAE model, comparing it against traditional methods, and highlights its particular strengths in estimating task load. The research contributes to the field by emphasizing the importance of individuality in multimedia quality assessment and offering a practical, empirically validated approach for incorporating individual differences into QoE models.

Introduces the Individuality Assisted Estimation model of experience for application in multimedia quality assessment Integrates psychological traits and states, and behavioral and physiological responses influencing quality perception Examines individual differences in quality perception, offering insights into user experience with multimedia content

Autorentext

Robert P. Spang, holding degrees in Computer Science from Technische Universität Berlin and Psychological Science from the University of Glasgow, combines his expertise in psychology, computer science, and cognitive neuroscience to drive innovation in Quality of Experience (QoE) assessment. His interdisciplinary approach has been instrumental in advocating for personalized QoE models that take into account individual psychological traits and states. At the Quality and Usability Lab at Technische Universität Berlin, he has challenged conventional methods like mean opinion scores and signal-based metrics, instead exploring novel approaches to video telephony perception. Robert's research delves into the intricacies of how individual differences shape multimedia quality perception, offering fresh insights that enhance user experience (UX). Beyond video telephony, Robert also works in health technology and data science, always prioritizing individual differences and personal preferences. His innovative methodologies have yielded significant contributions to the field, including scientific papers, publicly accessible datasets, speeches, and presentations, underscoring his impact on both academic and industry practices. Robert has also made substantial contributions to standards organizations such as ITU-T and ETSI, reflecting his commitment to shaping future multimedia technologies.
