Smith of Xerox Palo Alto Research Center speaking on AARRKK:: TThhee AAlltteerrnnaattee RReeaalliittyy KKiitt 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. Monday, April 6, 1987, 7:30 p.m. MC5158 University of Waterloo Tea and Doughnaughts Served
