Evaluation of Human Cognitive Characteristics in Interaction with Computer
Nebojscarona ordevi, Dejan Rani · InTech eBooks · 2008
Understanding physical, intellectual and personal differences between potential users defines the level of understanding and fulfilling user needs. Regarding different human perceptual, cognitive and motor abilities can lead to universally usable interface development. Taking into account different aspects of user profiles confronts us with the challenges of physical, cognitive, perceptual, personal and cultural differences between users. In order to evaluate user performance in interaction with interface, we extend the concepts of existing XUAN interaction model. Extended model is named XUAN/t and extension is related to the equal treatment of interaction complexity both from the system and user. Based on the described model and psychometric concepts we have developed software CASE tool for testing cognitive as well as psychomotor abilities of user in humancomputer interaction. Test concept allows program-led testing of the target group and precisely quantifies user performance.
