“This seminar presents the current state of the art of evaluating user interface designs using models of human performance that are based on cognitive architectures. Such models can yield usability results without the delay and expense of user testing of prototypes, but because they are new and still under development, whether and how to apply them is a challenge. This seminar will survey current theory and practice; no ‘how-to’ of actual model construction will be presented; rather the goal is to enable a good choice of whether a modeling approach will be useful, and which type of model would be best to pursue.” (School of CS – CMU)
