Embodied Conversational Characters
as Individuals
16th July, 2003
Melbourne, Australia
in conjunction with
AAMAS2003 Conference

The goals of the "ECAs as Individuals" workshop are:

  • to bring together the growing ECA communities of the world;
  • to provide a forum for demonstration and discussion of new "ECAs as individuals" paradigms, applications and research;
  • to promote interaction between academic and industrial research;
  • to provide an opportunity to become part of a global network of ECA researchers and practitioners.

This workshop will bring both established and new researchers together to discuss the development, implementation and evaluation of ECAs as individuals , the current ECA state-of-the-art and to create a vision for the future of individual ECAs.

The origin of this workshop dates from a successful workshop on Embodied conversational agents - let's specify and evaluate them! for AAMAS 2002, Bologna in mid July 2002 and a special IST 5th Framework meeting on Representation Formats/Languages.

The Workshop Organisers would welcome the submission of papers on substantial, original, and unpublished research on all aspects from the Major Topic areas. These include (but are not limited to)

  • identification of the factors influencing expressiveness and individuality; the factors may come from linguistics, speech, emotion, personality, gesture, social relation and/or dialogue capabilities.
  • description, parameterisation, representation of such values;
  • evaluation of a particular representation of individualism - what are the useful features; what are the limitations; in how far are original requirements met ?

The full day workshop will feature a mix of paper presentations, demonstrations, and discussion rounds. The presentations should cover one of the several academic or industrial themes of the workshop and should be oriented toward:

  • Description and/or evaluation of ECAs as individuals with
    • Pointers, such as on-line demos or videos, to actual working examples that demonstrate their usage and practicality.
    • Pointers to evaluation results, eg, Individual ECA's believability, engagement, affect.
  • Design decisions for specifications or languages that control the individualism of ECAs.
  • Practical knowledge from evaluation of robust academic or commercial systems. Discussing the link between the targeted audience and actual outcomes of the system.

We especially invite papers/presentations/demonstrations of industrial ECA research and/or commercial ECA systems.

We strongly encourage you to demonstrate your work and to provide URLs to permanent web sites that contain examples of your system. To give us time to organize the technical requirements, if you are to demonstrate your system, we must be notified before 15th April . Contact us for details at: raytrace@vhml.org

The workshop will conclude with a panel discussion of:

  • Important issues raised within presentations,
  • A visionary glimpse of / plan for the future for ECAs as individuals.

At the end of the workshop, participants should have a broad understanding of the differing technologies involved in the production, development and directing of "individualised ECAs". They will have seen several ECA systems and will understand the problems associated with the technology. They will have contributed, through discussion, to the future development of individual ECA interfaces within the global context. They will also become part of a network of ECA researchers and practitioners.
