This paper presents an experimental investigation into input suitability for human-computer interaction during computer aided design operations. Specifically, three types of operations, synthesis, interrogation, and modification, are examined with respect to three different types of user interfaces, mouse, direct tablet, and indirect tablet. The study, using undergraduate student participants in an introductory engineering graphics course, demonstrates that the mouse performs the highest across the dimensions of completion time and number of errors. However, the direct tablet, using a pen like device directly on the visualization screen, shows promise.
