Pablo Cesar

Dr. Pablo Cesar is a researcher at the Distributed and Interactive Systems (DIS) group at CWI (The National Research Institute for Mathematics and Computer Science in the Netherlands). He has (co)-authored over 50 publications about multimedia systems and infrastructures, social media sharing, interactive media, multimedia content modeling, and user interaction. He actively participates in EC-funded projects, such as (current) REVERIE and Vconect, and (past) TA2 and iNEM4U; standardization activities such as W3C's SMIL 3.0; and collaborates in interesting open source projects such as the Ambulant Player and the MDCS (about multi-modal interfaces and multimedia). He has given tutorials about multimedia systems in prestigious conferences such as ACM Multimedia, CHI, and the WWW conference. He is editor of the book "Social Interactive Television: Immersive Shared Experiences and Perspectives". More information about Pablo can be found in his webpage and on his Twitter account.

Selected topic: Pablo Cesar is interested, among other topics, on socially-aware multimedia. It is a fact that multimedia social communication is filtering into everyday use. Videoconferencing is appearing in the living room and beyond (e.g., FaceTime, SkypeTV, Umi), television is becoming smart and social (e.g., Boxee, GoogleTV, GetGlue), and media sharing applications are transforming the way we converse and recall events (Twitter, Facebook, YouTube). The confluence of computer-mediated interaction, social networking, and multimedia are radically reshaping social communications, bringing new challenges and opportunities. Socially-Aware multimedia considers the social dimension of the mediated interactions between people as important as the characteristics of the media content and of the communication link. Even though this social dimension is implicitly addressed in some current solutions, further research is needed to better understand what makes a good socially-aware application. In other words, social interactivity needs to become a first class citizen of multimedia research. Relevant insights can be found within a number of disciplines such as multimedia research, human-computer interaction, and sociology. In particular, multimedia research provides quantitative metrics regarding multimedia objects (e.g., precision and recall) and multimedia systems (e.g., delay, jitter). Human-Computer Interaction (HCI) research incorporates both quantitative metrics and qualitative understanding regarding human perception (e.g., quality of experience); and sociology and communication science provide a better understanding about motivations and collective group behaviour (e.g., conversational and interaction patterns, strength of interpersonal ties)
