Human Factors and HMI

抄録

The Human Factors and HMI research project consisted of three tasks: A, B, and C, and started in FY2016 as a three-year project. Task A investigated the effects of system information on driver takeover performance. The provision of well-defined knowledge about the system before driving and experience of using the system were found to have a positive effect. The provision of some dynamic information about the system state was also shown to be effective. Task B investigated the effects of the driver state (readiness) on takeover performance and metrics of readiness. It was found that different driver states influenced takeover performance in different ways. Some metrics for states (readiness) influencing takeover performance were found. Task C investigated effective ways of functionalizing automated vehicles to communicate with nearby road users. An external HMI was found to be an effective additional cue for pedestrians to make a decision to cross a road when an approaching automated vehicle intended to yield but did not decelerate largely enough to clearly signal this intention. It was observed that the external HMI also induced unsafe behavior in some pedestrians. This report was produced in the middle of the third year of the project and does not include all the studies conducted in the project.
