Abstract

Despite the tremendous development and increasing availability of computers in working life, severe usability problems are frequently observed, leading to bad user acceptance, negative stress, anxiety, and even health problems for the users. We need to create a scientific foundation for the studies of humans interacting with computer systems to achieve a specific work task in a physical and psycho-social work environment. Interdisciplinary studies of systems analysis, software engineering, cognitive and perceptual psychology, sociology, organisation theory, human factors, and design and art, all contribute to the science of human-computer interaction (HCI). With an engineering approach to design, scientific principles, technical information and imagination can be used in the definition of a mechanical structure, machine or system to perform prespecified functions with maximum economy and efficiency. This thesis covers methods for the study and modelling of a human-computer system, focu...
