GOMS Models for Task Analysis
David E. Kieras · 2003
Analyzing a task into Goals, Operators, Methods, and Selection rules (GOMS) is an established method for characterizing a user's procedural knowledge. When combined with additional theoretical mechanisms, the resulting GOMS model provides a way to quantitatively predict human learning and performance for an interface design, in addition to serving as a useful qualitative description of how the user will use a computer system to perform a task. This chapter focusses on GOMS models as a task-analytic notation and how to construct them.
