Abstract

Over the last decade, feature creep and the convergence of multiple devices have increased the complexity of both design and use. One way to reduce the complexity of a device without sacrificing its features is to design the UI consistently. However, designing consistent user interface of a multifunction device often becomes a formidable task, especially when the logical interaction is concerned. This paper presents a systematic method for consistent design of user interaction, called CUID (Consistent User Interaction Design), and validates its usefulness through a case study. CUID, focusing on ensuring consistency of logical interaction rather than physical or visual interfaces, employs a constraint-based interactive approach. It strives for consistency as the main goal, but also considers efficiency and safety of use. CUID will reduce the cognitive complexity of the task of interaction design to help produce devices that are easier to learn and use.
