Distinction of Attention Decline Using Eye-Centering Phenomenon in Viewing Driving Video

Hiroaki Ogawa･Katsushi Asami (DENSO)･Takushi Kawamorita (Kitasato University)

The previously reported eye-centering phenomenon, in which gaze shifts toward the center of the visual field during decreased attention, has raised concerns regarding its applicability in driving environments, where forward gaze predominates. In this study, we confirmed that this phenomenon also occurs while viewing driving scenes and demonstrated its potential applicability for detecting attentional decline.

Development of an Intention Estimation Method Using Driver Gaze Behavior During Driving (First Report)

When reaching for a cup, humans typically look at the cup before extending their hand. In this way, gaze movements precede limb movements. By exploiting this characteristic, this study aims to develop a method for estimating the trajectory that a driver intends to follow (i.e., intention) from the driver’s gaze behavior prior to the execution of driving actions. In this report, we present human gaze characteristics that are related to trajectory generation.

Analysis of Driving Behavior of Automobile Drivers During Sudden Visual Field Changes Using a Driving Simulator (Report 1)
-Investigation of a Method for Reproducing Sudden Visual Field Changes and the Effectiveness of the Blind Spot Monitor (BSM)-

Yushi Mitsumori･Daisuke Ito (Kansai University)･Hiroshi Kuniyuki (Suwa Tokyo University of Science)

Driving behavior during sudden visual field changes and the effectiveness of the Blind Spot Monitor (BSM) were analyzed through driving simulator experiments. In a scenario assuming lane changes and stopping while a vehicle was approaching from behind, drivers with higher anxiety tendencies tended to require more time to stop, and the results suggested that auditory warnings may be more effective than visual warning lights for the BSM.

Effect of Forward Field-of-View Width on Motion Sickness During Fixed Gaze Inside a Car

To reduce motion sickness during in-car visual tasks, we investigated the effect of forward field-of-view restriction on motion sickness while rear-seat passengers maintained a fixed gaze within the vehicle interior. During figure-eight driving maneuvers with a maximum yaw rate of 15 deg/s, the motion sickness score (MISC) was lowest when the forward field of view within ±30° was occluded.
