Software Tool for Evaluation of Human Cognitive Characteristics in Interaction with Computer

This paper presents an extension of cognitive model for Human-Computer Interaction (HCI) - XUAN/t, based on decomposition of user dialogue into elementary actions (GOMS). Using this model, descriptions of elementary actions performed by user and system are introduced sequentially, as they will happen. Based on the described model and psychometric concepts, we developed software tool for testing sensomotor abilities of users for HCI. Software tool arranges tests into test groups for psychosensomotor and memory capabilities. User test results are stored in a database and available for further statistical analysis.
