Individualized Quality of Experience Estimation in Audiovisual Communication

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.
