Behavior Planning for Life-Like Characters and Avatars
In Conjunction with the i3 Spring Days '99
March 9th -10th 1999
Sitges, Spain

Workshop Information

What the Workshop is About

During the last decade, a growing number of research projects both in academia and industry embarked on the development of life-like agents as a new metaphor for highly personalized human-machine communication. Due to advances in computer graphics, the realization of visually appealing agents, either based on real video, cartoon-style drawings or even model-based 3D graphics, has become manageable. The visual appearance of an life-like interface agent is, however, only one side of the coin. To be useful, however, agents have to behave in a reasonable and natural manner. The workshop aims to bring together researchers and developers who share a common interest in all aspects of behavior planning for life-like agents. Topics of interest include, but are by no means restricted to the following:

Submission Details

We solicit the submission of abstracts (1-2 pages), demo proposals (1 page) and/or video-tapes (under 5 minutes) by January 16th 1999 (extended deadline). If at all possible, submit your abstract in electronic form (ASCII text) rather than printed copy: email to Your abstract should include:

Workshop Participation

Workshop attendance will be limited to maximally 40 people. We will give preference to those people who have submitted an abstract and are willing to present their work. If a selection of contributions has to be made, this will be done by the members of the organisation committee on the basis of the information provided in the abstracts. Invited participants will be given an opportunity to present their work and are encouraged to bring demonstration prototypes or videos with them. To a certain extent, participation without giving a presentation is possible.

The workshop is sponsored by i3, and probably there will be no or a very low workshop fee. However, you should indicate your interest in participating ASAP, to assure your place at the workshop.


All authors are invited to submit an extended version of their abstract (5 - 20 pages) for publication in a workshop proceedings by July 31st 1999. The best papers will be selected for a Special Issue on Behavior Planning for Lifelike Characters and Avatars of Artificial Intelligence Communications. You are encouraged to use LaTeX for the preparation of your camera-ready manuscript together with the corresponding AICom style file aicom.sty which you can reach following this link or by sending an e-mail message to aicom . A demo file is also available. For authors not using LaTex Instructions to Authors are available. #All accepted abstracts will be printed in an informal workshop proceedings. #Depending on the quality of the contributions that we will receive, we #will seek for further publication opportunities.


All attendees of the i3 Spring Days must register for the events (ese-conference on Monday 8, workshops on Sunday 7, Tuesday 9 and Wednesday 10) in which they wish to participate.
With regard to the overall structure of the Spring Days a per-day registration is possible. That is, people can register for all four days, for three days, two days, or for a single day only.
The conference site offers two Registration Packages:
Besides your registration at Melia Gran Sitges, you are kindly asked to notify
