Given that the design of the user interface for information retrieval systems is crucial for the exploitation of the ideas of ubiquitous computing, it is likely that the next generation interfaces will be more user-oriented. This suggests the need for detailed observational studies of users working in context in their everyday environment. The study on users' information retrieval from GUI Help systems has commenced this and will supplement the various empirical studies of both expert and novice users of CUIs and GUIs currently being carried out and planned, It. It is important that the needs and requirements of all types of intermittent and frequent users are considered, if ubiquitous computing is to become a reality and the information space is to become readily accessible to all.
