THE EFFECTS OF A SIMULATED HEAD-UP DISPLAY SPEEDMOMETER ON PERCEPTUAL TASK PERFORMANCE
研究比较了模拟抬头显示与仪表盘数字车速表对驾驶感知任务的影响，发现抬头显示能显著加快对显著线索的反应速度，对汽车安全有启示。
This study compared the effects of simulated head-up display (HUD) and dashboard-mounted digital speedometers on key perceptual driving tasks in a simulated driving environment. Subjects were 20 male and female volunteers ranging in age from 19 to 51 years. A videotape, taken from the driver's perspective, of a car traveling along a memorized route served as the test scene. While viewing the test scene subjects performed tasks related to navigation, speed monitoring, and salient cue detection. The simulated HUD speedometer produced generally superior performance on the experimental tasks; most important, it enabled subjects to respond significantly more quickly to the salient cues. Implcations for the effects of the HUDs on automobile safety are discussed.
