Abstract
The Lotus 1·2·3™ spreadsheet macro language provides a low-cost, readily accessible, and easy-to-use method for rapidly building prototypes of computer interface dialogue systems. This method of prototyping was used to evaluate specifications for the human interface component of a satellite ground control system. The prototype mimics the essential functional components of the interface dialogue, and is easily modified, making it possible to determine whether recommended changes in dialogue specifications produce actual improvements in dialogue design.
