The amount of complex information while driving is constantly increasing, leading to driver inattention and traffic accidents. Since the majority of this information is visual, the driver´s visual attentnion is deflected away from driving the vehicle. The driver´s visual load can be reduced without performance degradation by presenting secondary information multimodally, which implies possible safety benefits. However, methods to design multimodal in-vehicle information stimuli are lacking. The purpose of this paper is to present a design method using multimodal sketching in an iterative process. The applicability of the method is evaluated for designing audio-tactile stimuli for in-vehicle navigation.
