ABSTRACT
Interface analysis methods can be used to assess a number of different aspects associated with a particular interface, including usability, user satisfaction, error, layout, labelling, and the controls and displays used. A number of different types of interface analysis method are available, such as usability assessment, error analysis, interface layout analysis and general interface assessment methods. Layout analysis is similar to link analysis in that it is based on spatial diagrams of the product and its output directly addresses interface design. The questionnaire for user interface satisfaction is a questionnaire method that is used to assess user acceptance and opinions of human-computer interfaces. An operational version of the interface under analysis is also required for the task performance component of the QUIS analysis. The repertory grid method is an interview-based method that can be used to analyse participant perceptions or views regarding a set of similar products, systems or devices.
