Designing Help Systems Using a GOMS Model: Part 1. An Information Retrieval Evaluation
Abstract
Using the GOMS model (Card, Moran, and Newell, 1983), a help system was developed which was complete and well structured. The content of this help system was determined from the goals, operators, methods, and selection rules, needed to perform HyperCard (TM) authoring tasks. The index to these help methods, which was an integrated part of the system, was determined from the hierarchical goal tree provided by the GOMS analysis. To determine the effectiveness of using GOMS as a design aid for help systems, the GOMS help system was compared to a state-of-the-art help interface developed by Apple (R) Computer which was modified slightly for experimental purposes (Original help system). Two groups of 14 users, assigned to one of the two help systems, retrieved help information for 56 tasks separated into 4 sessions. Human- computer interaction, Online help, Information retrieval.
