Measuring the Success of Visual Communication in User Interfaces    

This article discusses three key areas of visual communication we address in user interfaces (UIs): conventional—emphasis on imitating generic forms that meet readers' expectations; icon recognition; visual appeal or 'look-and-feel'. The article uses five case histories to demonstrate how usability research has helped the authors evaluate the quality of visual communication in navigation, icon recognition, and look-and-feel. It describes some of the research methodology the authors use, with examples from the case histories. For each of the three topic areas, we discuss the lessons we learned from the case histories about both usability testing methodology and visual communication guidelines. We mention, but do not concentrate on, related topics such as visual clutter.

Replay TV

You've all heard of TiVo. Sure you have. TiVo is the hard-disk video recorder that automatically records all of your favorite shows. Then there's ReplayTV, the other leading brand. Late fall 2001, ReplayTV crossed over a line that should never have been crossed, one that threatened the future of consumer products.
