Human-computer Interaction lies at the crossroads of many research areas (computer vision, multimedia, psychology, artificial intelligence, pattern recognition, etc.) and is used in a wide range of applications. In particular, we are aiming at developing human-centered information systems. The most important issue here is how to achieve synergism between man and machine. The term ¡°human-centered¡± is used to emphasize the fact that although all existing vision systems were designed with human uses in mind, many of them are far from being user friendly. What can the scientific/engineering community do to effect a change for the better?
On one hand, the fact that computers are quickly becoming integrated into everyday objects (ubiquitous and pervasive computing) implies that effective natural human-computer interaction is becoming critical (in many applications, users need to be able to interact naturally with computers the way face-to-face human-human interaction takes place). On the other hand, the wide range of applications that use multimedia, and the amount of multimedia content currently available, imply that building successful computer vision and multimedia applications requires a deep understanding of multimedia content. The success of human-centered vision systems, therefore, depends highly on two joint aspects: (1) the way humans interact naturally with such systems (using speech and body language) to express emotion, mood, attitude, and attention, and (2) the human factors that pertain to multimedia data (human subjectivity, levels of interpretation).
In this tutorial, we take a holistic approach to the human-centered vision systems problem. We aim to identify the important research issues, and to ascertain potentially fruitful future research directions in relation to the two aspects above. In particular, we introduce key concepts, discuss technical approaches and open issues in three areas: (1) multimodal interaction: visual (body, gaze, gesture) and audio (emotion) analysis; (2) image databases, indexing, and retrieval: context modeling, cultural issues, and machine learning for user centric approaches; (3) multimedia data: conceptual analysis at different levels (feature, cognitive, and affective).
The following research areas will be covered:
Thomas S. Huang received the B. S. degree in electrical engineering from National Taiwan University, Taipei, Taiwan, R.O.C., and the M.S. and Sc.D. degrees in electrical engineering from the Massachusetts Institute of Technology (MI), Cambridge. He was with the Faculty of the Department of Electrical Engineering at MIT from 1963 to 1973 and with the Faculty of the School of Electrical Engineering and Signal Processing at Purdue University, West Lafayette, IN from 1973 to 1980. In 1980, he joined the University of Illinois at Urbana- Champaign, where he is now William L. Everitt Distinguished Professor of Electrical and Computer Engineering, Research Professor at the Coordinated Science Laboratory, and Head of the Image Formation and Processing Group at the Beckman Institute for Advanced Science and Technology. He is also Co-Chair of the Institute¡¯s major research theme (Human Computer Intelligent Interaction). During his sabbatical leaves, he has been with the MIT Lincoln Laboratory, Lexington, MA; the IBM Thomas J. Watson Research Center, Yorktown Heights, NY; and the Rheinishes Landes Museum, Bonn, West Germany. He held visiting professor positions at the Swiss Federal Institutes of Technology, Zurich and Lausanne, Switzerland; University of Hannover, West Germany; INRS-Telecommunications, University if Quebec, Montreal, QC, Canada; and University of Tokyo, Tokyo, Japan. He has severed as a consultant to numerous industrial forms and government agencies both in the United States and abroad. His professional interests lie in the broad area of information technology, especially the transmission and processing of multidimensional signals. He has published 14 books and over 500 papers in network theory, digital filtering, image processing, and computer vision. He is a Founding Editor of the International Journal Computer Vision, Graphics, and Image Processing and Editor of the Springer Series in Information Sciences, published by Springer Verlag.
Dr. Huang is Member of the National Academy of Engineering; a Foreign Member of the Chinese Academies of Engineering and Sciences; and a Fellow of the International Association of Pattern Recognition and of the Optical Society of America. He has received a Guggenheim Fellowship, an A. V. Humboldt Foundation Senior U.S. Scientist Award, and a Fellowship from the Japan Association for the Promotion of Science. He received the IEEE Signal Processing Society¡¯s Technical Achievement Award in 1987 and the Society Award in 1991. He was awarded the IEEE Third Millennium Medal in 2000. In addition, in 2000, he received the Honda Lifetime Achievement Award for ¡°contributions to motion analysis.¡± In 2001, he received the IEEE Jack S. Kilby Medal. In 2002, he received the King-Sun Fu Prize from the International Association of Pattern Recognition and the Pan Wen-Yuan Outstanding Research Award.
Alejandro Jaimes is an Advanced Multimedia Specialist at FXPAL Japan, Fuji Xerox, where he leads the efforts in Multimedia Analysis and Interaction. Dr. Jaimes received a Ph.D. in Electrical Engineering (2003) and a M.S. in Computer Science from Columbia University (1997) in New York City. He holds a Computing Systems Engineering degree from Universidad de los Andes (1994) in Bogota, Colombia. Prior to joining the Ph.D. program at Columbia he was a member of Columbia's Robotics and Computer Graphics groups, where he worked on projects related to computer vision and computer graphics. He has held summer research positions at AT&T Bell Laboratories, Siemens Corporate Research, and IBM (TJ Watson and Tokyo Research Laboratories). His recent professional activities include co-chairing the ACM Multimedia 2005 and 2004 Interactive Art program, and the PCM 2004 and ICME 2004 special sessions on ¡°Immersive Conferencing: Novel Interfaces and Paradigms for Remote Collaboration,¡± and ¡°Novel Techniques for browsing in Large Multimedia Collections¡± respectively. He is co-founder and co-chair of the Workshop on Technology for Education in Developing Countries (TEDC ¡¯05, TEDC ¡¯04, TEDC ¡®03), and serves as the TPC member for several international conferences (ICME, ICIP, CIVR, ICCV and ECCV Workshops on HCI, etc.), among others. His work has led to over 35 technical publications in international conferences and journals, and to numerous contributions to the MPEG-7 standard. He has 7 patents pending. He is a member of the IEEE and ACM.
Nicu Sebe is an assistant professor in the Faculty of Science, University of Amsterdam, The Netherlands, where he is doing research in the areas of multimedia information retrieval and human-computer interaction in computer vision applications. He is the author of the following books: Robust Computer Vision¡ªTheory and Applications (Kluwer, April 2003) and Machine Learning in Computer Vision (Springer, May 2005). He was a guest editor of a CVIU special issue on video retrieval and summarization (December 2003) and was the co-chair of ACM Multimedia Information Retrieval Workshops, MIR¡¯03 & MIR'04 (in conjunction with ACM Multimedia conferences). He also was the co-chair of the first Human Computer Interaction Workshop, HCI ¡¯04 (in conjunction with ECCV 2004) and of the IEEE Workshop on Human computer Interaction Workshop (in conjunction with ICCV 2005).
He is the guest editor of three special issues on multimedia information retrieval and human computer interaction in ACM Transactions on Multimedia Computing, Communication, and Applications, ACM Multimedia Systems, and Image and Vision Computing.
