A major challenge in making software easy for people to use is to design screen layouts that people can search efficiently. Although there has been a great deal of research on visual search, the field of human-computer interaction HCI still does not have an empirically validated model of the perceptual, cognitive, and motor processes that people use when they look for a known item on a computer screen. There are many guidelines to direct the design of computer screen layouts, but few if any have been explained in terms of how these processes give rise to the guidelines. This dissertation presents the first empirically validated models of the perceptual, cognitive, and motor processes involved in the visual search of computer menus, models that can be generalized to explain the cognitive processes involved in more general computer layout visual search tasks on a computer. These models should contribute to the design and analysis of more usable computer systems.
