It is commonly said that we live today in a multimedia age. Until recently, and except for broadcast television and radio, voice was still the sole communication mechanism. However, the diffusion of digital processing algorithms and hardware has brought images, music, and video into everyday life. The availability of open standards (such as JPEG, MPEG-X Audio and Video, H.26X) has had a major impact on this progression. Such standards have made the creation, and communication of (digital) data aimed at our most important senses, sight and hearing, simple, inexpensive and commonplace.
The growing heterogeneity of networks, terminals and users and the increasing availability and usage of multimedia content have been raising the relevance of content adaptation technologies able to fulfill the needs associated to all usage conditions without multiplying the number of versions available for the same piece of content while simultaneously maximizing the user satisfaction.
While universal multimedia adaptation is still in its infancy it has already become clear that, as delivery technology evolves, the human factors associated with multimedia consumption assume an increasing importance. In particular, the importance of the user rather than the terminal as the final point in the multimedia consumption chain is becoming clear. We are starting to speak about Universal Multimedia Experiences (UME) which provide the users with adapted, informative (in the sense of cognition), and exciting (in the sense of feelings) experiences. Following the same trends, the notion of ‘quality of service’ has to evolve to something more encompassing like ‘quality of experience’ where user satisfaction considers not only the sensorial and perceptual dimensions but also the important emotional dimension.
Sensations, perceptions and emotions play a central role in major multimedia applications such as video streaming, personal communications, and image and music libraries, determining final user satisfaction. In this context, this talk proposes a triple sensation-perception-emotion user characterization model for content adaptation and discusses adaptation tools and quality of experience metrics at the light of this model.
Fernando Pereira was born in Vermelha, Portugal in October 1962. He graduated in Electrical and Computer Engineering by Instituto Superior Técnico (IST), Technical University of Lisbon, Portugal, in 1985. He received the M.Sc. and Ph.D. degrees in Electrical and Computer Engineering from IST, in 1988 and 1991, respectively. He is currently Professor at the Electrical and Computer Engineering Department of IST. He is responsible for the participation of IST in many national and international research projects. He acts often as project evaluator and auditor for various organizations. He is a member of the Editorial Board and Area Editor on Image/Video Compression of the Signal Processing: Image Communication Journal, a member of the IEEE Press Board, and an Associate Editor of IEEE Transactions of Circuits and Systems for Video Technology, IEEE Transactions on Image Processing, and IEEE Transactions on Multimedia. He is an IEEE Distinguished Lecturer and member of the Scientific and Program Committees of tens of international conferences and workshops. He has contributed more than 150 papers to journals and international conferences. He won the 1990 Portuguese IBM Award and an ISO Award for Outstanding Technical Contribution for his participation in the development of the MPEG-4 Visual standard.
He has been participating in the work of ISO/MPEG for many years, notably as the head of the Portuguese delegation, chairman of the MPEG Requirements group, and chairing many Ad Hoc Groups related to the MPEG-4 and MPEG-7 standards. His current areas of interest are video analysis, processing, coding and description, and multimedia interactive services.
