Research Abstract

Today, we can find many risk-taking behaviors (e.g. hasty driving), and these have the potential to cause traffic accidents. In order to reduce traffic accidents truly, it is necessary to suppress the risk-taking behavior. In this research, we attempted to intervene in the driver's velocity perception using the superimposing display of the optic flow, to suppress the risk-taking behavior. The experiment using a driving simulator was executed in order to evaluate the velocity perception. As the result, it was confirmed that the flow influences the velocity perception, and this influence varied depending on the visual fields. The flow, which is presented in the central visual field, had been allowed to sense slower than no-flow condition always. On the other hand, the flow that was presented in the peripheral visual field varied the perceived velocity in accordance with its velocity. These results suggest that the superimposing flow can intervene in the velocity perception.
