Evaluating interaction—what is the right balance of user control and automatic processing when searching for information?  People did better and liked better the ‘penetrable’ interface for relevance feedback in the filtering task  [See Muramatsu & Pratt (SIGIR 01) for another study of making queries ‘transparent’ in 4 ways: automatic Boolean operator; stop word removal, term suffix expansion, and term order sensitivity---in this case, search task but look at user’s mental models---not a quantitative comparison…poor mental models]         

Christel et al.

Evaluating video skims: video retrieval and multiple features.  5 alternative system instances (baseline long and short, new, best audio, full).  Integration of multiple features the best direction….implications for giving users more control at the risk of overload.  [See Wildemuth et al (JCDL 04) for a study examining fast forward rates for video
