Outline of Final Research Achievements |
This study has examined how factors such as users, tasks and network environments affect QoE (Quality of Experience) in multimedia communications in quantitative ways; taking into consideration the influencing factors thus clarified, it has developed fundamental technologies for QoE enhancement. First, we have written a textbook on fundamental technologies of information networks by setting an organized structure of QoE and QoS (Quality of Service) as its framework. We have also improved, extended and/or merged individual QoE enhancement technologies, which include a QoE-based video output scheme SCS for audiovisual communications, Multi-View-Video and audio communications, Media Adaptive Buffering (MAB) control in haptic-audiovisual communications, and user-assisted QoE enhancement with graphical user interfaces. In addition, we have built Bayesian statistical models of QoE, which was never found in previous studies on QoE worldwide.
