Abstract
This study aims to investigate drivers' directional judgments and psychological aspects at intersections when using metaphor for route guidance of AR-HUD. In the VR experiment, experimental conditions were consisted of yaw and roll angles of the metaphors and the number of metaphors. Participants approached a left-turn intersection which was divided to three directions while experiencing various combinations of metaphor design of AR-HUD, and then asked to judge what direction the metaphor indicated. Experimental data were analyzed and evaluated in terms of reaction time and psychological aspects.
