I was sorting through some old and priceless documents, such as the five year-old proceedings of a CHI (Computer Human Interaction) conference. In it I encountered a thesaurus that lists 137 terms that crop up in the papers selected for the event. The list runs from agents, to work analysis, and includes, in-between, such subjects as augmented reality, cognitive models, ethnography, help desks, input devices, metaphors, predictive interfaces, story-telling, tactile inputs, and usability engineering. As I said, 137 entries. Now CHI is for and about designers who care passionately about people – but you have to ask: is it possible to stay on top of this kind of burgeoning knowledge-base and still find time to get out of the house and mix with….real people?
