Evaluation of a New In-vehicle HMI System Composed of Steering Wheel Switch and Head-Up Display when a Driver Encounters Sudden Danger

We conducted an experiment to evaluate the operational convenience and the influence on safe driving of a new human-machine interface (HMI) by using a driving simulator (DS). In this system a driver operates the new HMI and center-cluster panel switches while driving on an expressway and when encountering a sudden danger. Based on the results, we discuss the operational convenience and driving safety when operating an HMI while driving on a virtual expressway.
