Following a general trend in software development, CDROM applications are increasingly implementing Graphical User Interfaces (GUIs). The general assumption is that GUIs offer advantages in terms of ease of learning and use, especially for non‐expert users. Moreover, the adoption of GUIs for CDROMs has been suggested as a means of providing a de facto standard interface. This study assesses the appropriateness of GUIs, more specifically Windows‐based interfaces for CDROM. An evaluation model was devised to carry out an expert evaluation of the interfaces of seven CDROM products. The model identified two levels of interaction, the dialogue level and task level, and focused on general interface features, search and retrieval tasks, and output and processing options as well as the help facilities. The results are discussed in the light of HCI Usability Criteria and design guidelines (including general interface design guidelines, specific Windows design guidelines and The CDROM Consistent Interface Guidelines) to assess to what extent the applications comply and appropriate recommendations are made.
