Emerging trends in search user interfaces

What does the future hold for search user interfaces? Following on a recently completed book on this topic, this talk identifies some important trends in the use of information technology and suggest how these may affect search in future. This includes is a notable trend towards more "natural" user interfaces, a trend towards social rather than solo usage of information technology, and a trend in technology advancing the integration of massive quantities of user behavior and large-scale knowledge bases. These trends are, or will be, interweaving in various ways, which will have some interesting ramifications for search interfaces, and should suggest promising directions for research.
