The Alternate Reality Kit (ARK) is a project under development in
the Xerox PARC System Concepts Laboratory. ARK is an animated
environment for creating interactive simulations. It is a kit of
parts in which users can assemble their own ``microworlds.'' The
interface is quite faithful to a physical world metaphor: all ob-
jects have a visual presence, a velocity, and can experience
forces. One of the objects on the screen is a disembodied hand,
which moves around in response to a mouse. The user's ``hand''
can carry and throw objects, and can press buttons. In ARK, even
the underlying simulation laws are represented by physical ob-
jects called interactors. Interactors are important actors in
the story of how ARK attempts to enable intuition by making
abstractions concrete. Although the implementation is still
evolving, ARK has already hosted dozens of experimental subjects.
This presentation will feature videotape of the system, discuss
the underlying motivations for the design, and describe some of
the experiments. Future plans, which include making ARK a self-
contained programming environment, will be discussed.
