Shive, Joshua and Francis, Gregory (2008): Applying models of visual search to map display design. In International Journal of Human-Computer Studies, 20 (2) pp. 67-77

“We explored how to use a computational model of visual search to design a map of a mall directory. We parameterized the Guided Search model [Wolfe, J.M., 1994. Guided Search 2.0: a revised model of visual search. Psychonomic Bulletin and Review 1(2), 202-238] for a task involving visual search of a target store in a map. The resulting model was then used to choose color assignments for all the elements of the display that would result in the fastest average search time for the display and search tasks. These predicted optimized color assignments were then tested empirically. The empirical data closely matched the predicted pattern of search times. We conclude that computational models of visual search are sophisticated enough to contribute to the development of optimized map designs, discuss some limitations of the current models, and suggest directions for further development.”

Liu, Baili, Francis, Gregory and Salvendy, Gavriel (2002): Applying models of visual search to menu design. In International Journal of Human-Computer Studies, 56 (3) pp. 307-330

“The Guided Search (GS) model, a quantitative model of visual search, was used to develop menu designs in a four-step process. First, a GS simulation model was defined for a menu search task. Second, model parameters were estimated to provide the best fit between model predictions and experimental data. Third, an optimization algorithm was used to identify the menu design that minimized model predicted search times based on predefined search frequencies of different menu items. Fourth, the design was tested. The results indicate that the GS model has the potential to be part of a system for predicting or automating the design of menus.”

“ Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context. ”
