TV'03: the 3rd Workshop on Personalization in Future TV in conjunction with User Modeling 2003 Pittsburgh, PA, USA June 23rd, 2003 Background and motivation There are large differences in types of users (e.g., ages, languages, ethnic backgrounds) and ranges of viewing purposes (e.g., enjoyment, business, education and learning, etc.) witness speciality stations in sports, business, economics, biography/history, etc. The diffusion of digital TV and the availability of hundreds of TV channels are exciting challenges for the design, development and exploitation of user modeling, personalization and adaptive user interfaces techniques. First of all, personalized Electronic Program Guides (EPGs) are needed to support the TV viewer in the selection of the interesting programs. Second, the presence of Set-top boxes running complex programs facilitates the development of user modeling systems that monitor the viewer's behavior each time (s)he watches TV, acquiring long-term user models. At the same time, however, there are important issues to be solved: for example, viewers typically do not watch TV alone; therefore, household models have to be acquired and efficient unobtrusive identification techniques have to be developed to make the explicit identification unnecessary. Moreover, the viewer's interests have to be acquired without bothering her/him with questions and, as such interests may abruptly change, the system has to promptly react to such changes to provide suitable recommendations. Finally, privacy issues have to be addressed to make such systems acceptable. Another important challenge for digital TV is the development of suitable user interfaces for TV services. For instance, the transition from a passive type of interaction to an active one and the need to use simple remote control devices constrains the types of actions that the TV viewer can perform. Moreover, as the TV is located far away from its viewers, there are special constraints on the layout of the user interfaces. Finally, increasingly sophisticated and interactive games will provide additional challenges. And new forms of interactive television promise to place the viewer in the drivers/design seat. The previous TV workshops The 3rd workshop on Personalization in Future TV follows TV'01, held in association with the 8th Int. Conf. on User Modeling (Sonthofen, 2001), and TV'02, organized in conjunction with the 2nd Int. Conf. on Adaptive Hypermedia and Adaptive Web Based Systems (Malaga, 2002). Both TV events have been organized as forums in which researchers from diverse areas such as machine learning, knowledge engineering, cognitive sciences, adaptive user interfaces, and business intelligence could share their experiences in the design, development and exploitation of user interfaces for future TV services. After the success of such workshops, which attracted the attention of academic and industrial researchers and provided an excellent overview of the current international work in the area of digital TV, we propose the third edition of such event, to be held in Pittsburgh in conjunction with the UM 2003 Conference. Call for papers For this workshop, we will consider contributions devoted to user modeling and user-adaptive systems in the field of Personalized TV Applications available on the Web and on new generation TV-sets. In order to focus the themes addressed during the workshop, the submitted papers should try to address at least one of the following questions: 1. Will users prefer personalized television over traditional television? 2. What are the unknown usability problems for digital TV applications? What testing methods could be applied to assess the usability of TV services? 3. What are the most effective algorithms for selecting shows relevant to viewers' personal interests? 4. What is the most intuitive personalized interface for users to browse and select programs? 5. How can privacy be managed and balanced against needs for personalization of massive television data? 6. What is the best way to convey user preferences to the computer? 7. Are stereotypes more effective than individualized models of users' television interests and preferences? Workshop format This workshop is intended to provide a forum in which researchers from diverse fields such as machine learning, knowledge engineering, psychology, cognitive sciences, adaptive user interfaces, user modeling and business intelligence can examine the personalization aspects of the user interface in interactive TV. During the workshop, the authors presenting their work should try to answer at least one of the previously listed questions. Notes will be taken, in order to produce a summary of the contributions. At the end of the workshop, a discussion session will be held to summarize the results of the presentations. All contributions will be made available in a Web site before the UM'03 Conference, so that people can read them in advance. If possible, the proceedings will also be published as an informal Annex to the main Conference Proceedings. In order to participate to this workshop, one of the following is required: * present a contribution to the workshop (long paper, short paper or demonstration, see below) * submit a short interest statement describing current work and interests as related to the workshop topics. Important Dates: * Submission of contributions: March 14, 2003 * Notification of acceptance: March 25, 2003 * Submission of final contributions: May 10, 2003 Submission instructions: The following types of submission are solicited: * Long paper submissions, describing substantial contributions of novel ongoing work. Long papers should be at most 10 pages long. * Short paper submissions, describing work in progress. These papers should be at most 5 pages long. * Demonstration abstracts: software demonstrations are wellcome and should be described in a short abstract outlining the key features of the system to be demonstrated. The abstracts should be at most two pages long. Notice that the authors are expected to bring their own equipment for running the systems during the workshop. All the submissions should be formatted according to the guidelines used for the papers of the main conference (see http://www2.sis.pitt.edu/~um2003/). Suitable templates (LaTex2e | LaTex | Tex | MS Word (PC)) may be retrieved from the LNCS Web site at the following URL: http://www.springer.de/comp/lncs/authors.html. Electronic submission of the URL address of the paper is preferred, although e-mail submissions of the Postscript/PDF files will be accepted. Send your submission to liliana@di.unito.it.
