This article reports on a study of route guidance using a navigation system that receives location information from a Global Positioning System receiver. Fifteen visually impaired participants traveled along 50-meter (about 164-foot) paths in each of five conditions that were defined by the type of display interface used. One of the virtual displays-virtual speech-led to the shortest travel times and the highest subjective ratings, despite concerns about the use of headphones.
本文报道了一项关于使用导航系统进行路线引导的研究，该导航系统从全球定位系统接收器接收位置信息。15名视力障碍参与者在由所使用的显示界面类型定义的五种条件下，沿着50米（约164英尺）的路径行走。尽管有人担心使用耳机，但其中一种虚拟显示——虚拟语音，导致了最短的行进时间和最高的主观评分。
