Evaluation of a New In-vehicle HMI System Composed of Steering Wheel Switch and Head-Up Display - Comparison with a center-cluster panel when the number of switch pushes is the same for each HMI - 2008-01-0559

In this paper, we discuss the operational convenience and safe driving when operating a human-machine interface (HMI) while driving on a virtual expressway. We previously conducted an experiment to evaluate a center-cluster panel switch and two prototypes of new HMI with a head-up display (HUD) and steering wheel switch (SWS) in which the participant followed a lead vehicle on an expressway by using a driving simulator (DS). We also conducted another experiment to evaluate these new HMIs when a driver operating an HMI encountered a sudden danger while driving. However, in these previous experiments, the number of switch pushes was not the same for each HMI. In this study, we compared the participants' switch operation performance, eye movement, and reaction to sudden danger in the new experimental condition, where the number of switch pushes is the same for each HMI, with those of the previous work.
