The creation of the Action Catalogue involved the programming
of A2A rules for the actual reuse of the stored animation data. The
animator and the 3D programmer analyzed the structure of each
primitive action included in the plan library to translate it into
the animation language, possibly reusing clips stored in the Animation
Data Repository. Most of the actions had to be produced from
scratch as animation clips. This is the case for primitive actions,
such as !Talk, !Put-down, !Write-line, corresponding to the
units Uttering, Taking, Writing, identified during the breakdown of
the original animation. For other actions, however, an existing clip
(or pose) was embedded in an A2A mapping rule, such as walk and
grab-one-hand. In the experiment, we developed 9 direct correspondences
between action and animation and 3 A2A rules, with
a use of action parameterization. However, given its short duration,
the animated scene did not include any reuse of animations across
different actions.
