Drivers' properties to detect visual targets was investigated. White dot targets were presented on a screen, and both error rates and detection times were measured. The investigated factors affecting the detection were as follows: presentation type (appearance or changing size), target size, and background. In the results, more detection errors were observed for a small target presented far from the fixation point upon dot-texture background. The following factors increased the target detection times: presenting target in peripheral regions, lower rate of changing size, small size, and dot-texture background. "Detection maps" were illustrated to understand the drivers' visual detection properties intuitively.
