Young Driver Preferences and Experimental Investigation of Audio and Visual Interface Designs for In-Vehicle Information Systems

Of all the in-vehicle information systems (IVISs) available, Collision Avoidance Warning Systems (CAWSs) and in-vehicle Route Guidance Systems (RGSs) are particularly helpful and attractive to drivers, enabling them to reach their destinations with greater ease and safety. As these two advanced systems become popular, it is important to design system user interfaces that do not distract the drivers¡¦ and threatening their safety. This study used focus groups to investigate drivers¡¦ concerns and preferences regarding CAWS and RGS audio and visual interface designs. Four types of IVIS devices were included: beep sounds, voice messages, a heads-up display (HUD) and a liquid crystal display (LCD). A driving simulation experiment was conducted to determine the best HUD location. Focus group discussions suggest that the CAWS interface should have an audio message combining beep sounds and a voice message indicating the direction of danger (e.g., beep-beep-¡§right¡¨), or provide beeps and display the direction of danger on a HUD. Considering gender, road event and road type factors, data analysis reveals that the best HUD location is positioned at column -5 degrees and row -5 degrees.
