Usability Evaluation of User Interfaces with the Computer-aided Evaluation Tool PRO-KUS

Because of the increasing use of data processing in all fields in human life (e.g. work, education, leisure) the attention to a user-friendly software design is rising more and more. The quality and acceptance of an interactive human-computer system highly depends on the ergonomic design of the user interface. In the past, ergonomic aspects were often neglected when developing software and information systems. Thus, many users complain about the troubles in learning to use a software product or its insufficient functionality and complexity of interactions. Once the user gets dissatisfied with a software product, a dialogue system or an accessible interface, this dissatisfaction dominates the functionality and the productivity of the system.
