	 Automating the creation of explanatory pictures

The APEX [Automated Pictorial EXplanations] project has as its
long-term goal the real-time computer generation of effective
pictorial and textual explanations.  Our current research has
concentrated on the creation of pictures that depict the perfor-
mance of physical actions, such as turning or pushing, on ob-
jects.	The research combines techniques of artificial intelli-
gence and computer graphics.

We are constructing a test-bed system that generates pictures of
actions performed by a problem solver.	Our system supports rules
for determining automatically the objects to be shown in a pic-
ture, the style and level of detail with which they should be
rendered, the method by which the action itself should be indi-
cated, and the picture's viewing specifications.  A picture crys-
tallizes about a small set of objects inferred from the nature of
the action being depicted.  Additional objects and detail are ad-
ded when it is determined that they help disambiguate an object
from others with which it may be confused.
