In this paper we present an approach to define reusable
gestures for embodied web agents, defined according to the H-Anim
standard for VRML.
We identify the dimensions to compare gestures and
criteria to circumscribe a set of gestures
an avatar should be endowed with.
Based on these dimensions and criteria we propose
a uniform way to define a wide range of gestures,
that may be adapated to particular circumstances and
personal style.
We have implemented our gesture library in STEP,
which is a scripting language for humanoids based
on dynamic logic.
We will discuss the example of conducting music, to
explain our approach to
the parameterized definition and control of gestures.
We conclude by briefly discussing issues for
future research.
was:
We developed and implemented in our STEP language a framework for defining gestures for avatars in VRML.
In this paper we focus on the reusability aspects of gestures. We identify the dimensions to compare gestures and criteria to circumscribe a set of gestures an avatar should be endowed with.
Then we discuss the parameterized definition and control of gestures. We show examples from one of the implemented demonstrators, the conductor.
