Human Performance Modeling for Usability Assessment - overview
Extending human performance models of skilled behavior to predict usability for a broader range of users using new types of devices, and new styles of interaction.
Our on-going research is extending our models to predict performance of older adults, novice's as they explore a new interface and use of mobile devices.
We are extending CogTool with these additional models. CogTool is an open source, general purpose user interface prototyping tool that uses a human performance model to automatically evaluate how efficiently a skilled user can do a task on a design.
