This text investigates the foundational principles and technical implementation of interactive graphical systems within the context of computer-aided design. Prince provides a technical overview of the hardware and software requirements necessary to bridge the gap between human input and machine-generated visual output. The work serves as a primary reference for understanding the early computational frameworks that enabled engineers to manipulate geometric data in real-time environments.

Experts recognize this work as a foundational text that documents the early development of CAD systems. Readers frequently note the technical density of the prose, which reflects the specialized computing environment of the early 1970s.
