Call For CHI2003 Workshop on Subtle Expressivity For Characters And Robots

Humans, both consciously and unconsciously, use subtle expressions to communicate their emotions and intentions through variations of the gaze direction, pitch of speech and gesture speed. They form their own class of communication acts. Embodied characters, including robots, need to use subtle expressions to become believable communication partners.

The design and evaluation of subtle expressivity are challenges for designers and researchers of embodied characters. How do the subtle variations in expression influence the interaction? What types of subtle expressions are most important for the design of interactive media? How can the effect of the expressions be reliably measured?

The workshop aims to:

  • Provide a forum to discuss emerging issues in the design and evaluation of subtle expressivities and its applications.
  • Discuss the role of cognitive science and psychology in the use of subtle expressions in the design of interactive media.

We plan to cover the following topics:

  • Concepts, theories or guidelines for design of subtle expressions
  • Implementation methods for of subtle expressions
  • Measuring methods for the effects of subtle expressions.
