Abstract
In driving situation, drivers encounter a sudden pedestrian or intruding car in a while. At that time, they have to detect the obstacle and push the brake pedal as quickly as possible. In most of cars, the brake and accelerator pedals are in the right side regardless of the driver’s left or right seat. So, they always use the right foot to control the car. However, human perceptual manual responses like pushing the brake pedal may vary according to a lateral visual field including the target. In other words, this setting may incur poor performance because of the violation of the stimulus-response compatibility, namely, the mappings of display elements to control elements. In this perspective, the present study including a driving simulation examined the complementary probability of the crossmodal audiovisual display enhancing the latency and accuracy relatively to a single modality in the information processing. In particular, a crossmodal cue was presented simultaneously or asynchronously with SOA 150ms to prevent a crossing pedestrian (i.e. visual target) from injuring or dying. As the result, in the crossmodal presentation of an auditory cue and a pedestrian the response difference between two sides was smaller. In conclusion, this study suggests the crossmodal audiovisual display to overcome a driver’s intentional disadvantage in a certain side.
