Usability Makeover of a Cognitive Modeling Tool

FEATURE AT A GLANCE: In this article, we describe a new software tool that was developed for modeling human performance and mental workload in single- and dual-task situations. The tool features an interactive interface and is based on psychological theory. Using this new modeling tool, in most cases, users can model and predict human performance and workload by clicking buttons to select options without needing to learn a new programming language. They can also visualize the information-processing state of the model during simulation and compare and evaluate the simulated human performance and mental workload for different user interface designs based on the simulation results.
