CORE/X-PRT

A suite of usable cognitive modeling tools designed to interact with the HCI Group's own CORE modeling engine, the goals of this toolkit are to allow extremely fast and easy model building and innovative visualization of PERT-chart-like timecourse output.

Tools to help interface designers predict human performance.

Based on optimal scheduling, the CCM approach is implemented in a tool called CORE (Constraint-based Optimal Reasoning Engine). CORE represents the basic theoretical assumptions of the approach. It includes libraries of constraints derived from twenty years of research in Human-Computer Interaction and can be used to deduce the consequences of these constraints for behavior in a particular task environment. In order to make CORE usable in the context of applied human-computer interaction design, an integrated set of support tools is under developement in the form of X-PRT (Expert-Performance Research Toolkit ). CCM-based tools can help designers predict the time that a user will require to achieve tasks with a given interface. They can also be used to make predictions about speed-accuracy trade-offs in task performance and changes in performance through the process of skill acquisition (novice to expert).
