Towards Real-Time GOMS.
John, Bonnie E.; And Others
This report presents an analysis of an expert performing a highly interactive computer task. The analysis uses GOMS models, specifying the Goals, Operators, Methods, and Selection rules used by the expert; the GOMS models are implemented within a unified theory of cognition called Soar. Two models are presented, one with function-level operators, performing high-level functions in the domain; and one with keystroke-level operators, describing hand movements. For a segment of behavior in which the expert accomplished about 30 functions in a computer game in about 30 seconds, the function-level model predicted the observed behavior well, while the keystroke-level model predicted only about half of the observed hand movements. These results, including the discrepancy between the models, are discussed. Appendices include a transcription of observed behavior, predictions of the GOMS models, and a comparison between observed expert behavior and predictions of the GOMS models.
