Larger and higher resolution screens that support multiple windows are now widely available. They are often used to traverse hypertext databases for fact retrieval, education or casual browsing. This paper introduces window control strategies that we implemented, describes their cognitive complexity, and characterizes the tasks that users might encounter. An infomal usage by dozens of visitors and a usability test with four subjects performing information search tasks revealed the limitations of several strategies and guided us to select user control of article placement in a tiled non-overlapping multiple window display.
