Hypertext/Prolog user interface for a flexible inspection cell

An inexpensive but versatile human-computer interface (HCI) for a machine vision system is described. Widely available hardware and computing components are controlled by software based on HyperCard and Prolog. While considerable benefit is obtained using just one of these programming tools, it has been found that the combination provides many advantages, including ease of use and great flexibility. Details of what is possible using HyperCard and Prolog individually and both working in harmony are discussed.
