Abstract

Even if a system's hardware and software underpinnings are completely reliable, errors at the user interface can cripple or destroy a mission, often with catastrophic consequences. Little attention has been paid to handling faults and errors at the user interface; their causes and remediations are little understood, and methods of predeployment fault detection in user interfaces are almost nonexistent. This paper presents a working definition of a user interface defect, and a robust method for detecting defects automatically. An experimental methodology for empirical testing and validation is given. Results show that while manifestations of defects may be many, only a few root causes are responsible for them.
