The Rise of Contextual User Interfaces
Read Write Web has an interesting article on the concept of the contextual user interface. A contextual user interface - as the name implies - is an interface which adapts to the current wishes of its users, the context. The interface will change according to the actions the user takes; present a set of minimal options, and show other options as the user goes along. While the article makes some good points, it also contains some generalisations that I find rather debatable.
