Abstract
Due to the rapid development of high-speed train automatic driving, the combination forms of multimodal interface are various. In order to determine the differential effects of visual interface location and auditory interface on takeover efficiency and validity in high-speed train automatic driving scenario, 48 participants were selected to conduct multimodal interface simulation takeover test of high-speed train automatic driving, and the takeover reaction time, takeover completion time, takeover errors, SUS scale and generalized anxiety disorder scale were analyzed by variance analysis and Mann-Whitney U test. The results show that non-speech type auditory interface can attract drivers 'attention faster, and has significant advantage in takeover response, but it should avoid the anxiety caused by startle effect when used. Finally, reasonable TOR interface design suggestions for high-speed train autopilot are formed, which can provide theoretical basis for interface design of high-speed train autopilot, and provide new research methods for evaluation and optimization of train man-machine cooperation.
