GOMS modeling of user interfaces using NGOMSL

Abstract

This tutorial will present the NGOMSL methodology for constructing and using GOMS models for use in analytical user interface design evaluation. The first half-day will present the basic concepts of GOMS models, the NGOMSL notation, a procedure of conducting the analysis, and obtaining and using usability predictions. The second half-day will be a lab session in which with the help of the instructor, participants will construct and make use of a GOMS model for a suitable subset of a user interface design.
