Efforts to incorporate intelligence into the user interface have been underway for decades, but the commercial impact of this work has not lived up to early expectations, and is not immediately apparent. This situation appears to be changing. However, so far the most interesting intelligent user interfaces (IUIs) have tended to use minimal or simplistic AI. In this panel we consider whether more or less AI is the key to the development of compelling IUIs. The panelists will present examples of compelling IUIs that use a selection of AI techniques, mostly simple, but some complex. Each panelist will then comment on the merits of different kinds and quantities of AI in the development of pragmatic interface technology.
