Acetabular Implant Alignment

Abstract

We describe a methodology for evaluating the user interface components of a pre-operative planning system for performing complex 3-D spatial manipulation and reasoning tasks. The design of a pre-operative planning system for the alignment of acetabular implants in total hip replacement (THR) surgery is used as an example. For this application, we have implemented several alternatives to two of the planner 's sub-systems. We report the results of a pilot study which evaluate these alternative components with respect to task and user specific design criteria.
