Abstract [en]

How can we arrange a large number of information items on the screen and still keep the average search time as short as possible? This question is of interest especially when designing displays for frequent professional use. A simple model of the visual search process was used to rank order competing display designs. Input to the model included characteristics of the display design and some knowledge or assumptions regarding a representative search task. Output from the model included predictions of the average time required for information search. The model was validated by application to 41 display designs described in the literature. Comparison of predicted and observed search time data showed that the model explained 94% of the variance. The most effective display designs are those that exploit the peripheral visual system. Less effective methods are those that require extensive use of the foveal visual system. Implications for display design are discussed.v
