The Effect of Video Viewing before Driving on Driving Behavior: Analysis of Drivers with Different Levels of Trait Anxiety

Chihiro Shumiya･Yukiko Nishizaki (Kyoto Institute of Technology)

Video contents influences emotions or post-viewing behavior. However few studies have examined the effects of watching videos before driving. Negative videos, in particular, may adversely affect drivers with high trait anxiety. This study experimentally examined the impact of qualitatively different video content on subsequent driving behavior and its association with individual differences in trait anxiety.

Evaluation of Driver Trust in in-Vehicle Driving Assistance Information Across Various Situations using Physiological Data

To quantitatively evaluate driver trust in the provided information for driving assistance, we tested the potential use of physiological data. Central nervous system responses to appropriate and inappropriate information were investigated using a driving simulator and physiological measurements. By analyzing event-related potentials (ERPs) under each condition, we found differences in the characteristics of late components of the ERPs. This indicates that physiological data can be useful for assessing driver trust in various driving assistance information.

Evaluation of Effect of the Roll Component of Shaking on the Operability of Information Terminals

With the spread of AD and ADAS, improving comfort during the second task is also an important issue. In this study, operability of a tablet device was evaluated from body behavior, eye movement, and stress indices when operating the tablet on a ride comfort evaluation test device that can reproduce the driving waveform of a passenger car. As a result, it was clarified that the roll component of shaking has a large contribution to the deterioration of operability.
