Abstract
We investigated effect of location of information in the visual field and effect of age on the criterion adopted in a visual detection task. The task was carried out in a complex visual environment as seen by car drivers. Criterion was recorded in 150 healthy participants with ages ranging between 15 y and 67 y. Results show a significant effect of location. In visual periphery, participants adopted a more conservative criterion as was the case in the central visual field. With increasing age, a more conservative criterion was adopted. We conclude that costs for wrong decision were rated higher in the peripheral task than was the case for the task in the central visual field. This conclusion has implications in the design of information layout in augmented reality systems used in cars. Drivers could benefit from assistant systems detecting and processing peripheral information.
