(1987) Alternate Reality Kit: Randall Smith

This video is an overview of the Alternate Reality Kit (ARK); an animated environment for creating interactive simulations. ARK is built upon a physical-world metaphor: all objects have an image; a position; a velocity; and can experience forces. Users manipulate objects wiha mouse-operated "hand" which enables them to carry and throw objects; to press buttons; and to operate sliders. Discussion of each ARK feature includes informal observations of early ARK users; an assessment the feature's learnablility; of its usefulness; and of its position on the magical-literal axis.
