Although the idea of making technology more context aware is an alluring one, this seemingly simple move hides a great deal of complexity. Even simple examples such as a context sensitive mobile phone which knows when not to ring, are unlikely to be successful. Any context sensitive technology is likely to make mistakes - like ringing in the middle of a film, or not ringing for an urgent call. Using three examples from fieldwork of alerting systems (two ringing phones and one medical alarm in a hospital), we suggest three guidelines for context systems which could genuinely assist users. First, we argue that context sensitive computing should be used defensively, where incorrect behaviour is tolerable. Second, that technology can provide structures to which people themselves can add context. Third, that technology can communicate context to users, allowing users to make sense of that contextual information themselves. Lastly we argue for an understanding of the long term use of technology use, dwelling with technology, a process which changes how the world is seen and experienced.
Biologists are aware that sexual dimorphism can result from size differences, shape differences, and differences in the relationship between the two (allometry), but the digital human modeling community has not fully ...

This work proposes a user-oriented approach as a basis for proper information visualization in the production automation area. A total consideration of the user consists of analyzing his tasks, context and profile. In order to implement this in the visualization process, an intelligent framework that is based on a multi agent system is developed. The advantage is that the tasks can be distributed to several small and manageable agents. The long term objective is to develop a working platform for the user-oriented information visualization.
A new interactive floorspace has been developed which uses modular nodes connected together to create a pressure-sensitive area of varying size and shape, giving it the potential to be integrated into an interactive e...

Within the software development process, reuse at the requirements level has become an increasingly more compelling notion. Following a human-centric approach, this work focuses on both requirements and design solution reuse using a design knowledge repository. In recent years, many improvements have been made to increase reuse through design knowledge repositories, but retrieval of knowledge in the context of design activities continues to be a formidable challenge. We propose a new system, called CERVi, to browse a repository through visualization by exploiting relationships between units of knowledge (in our case, claims). These relationships are key to finding the most appropriate reusable knowledge based on design conditions. Testing shows that CERVi enhances the design knowledge selection process and helps users proceed through structured design decision making. Our approach would be most useful to those interested in unlocking the potential of design knowledge reuse.
