Abstract

Objective: This study aims to clarify the gazing characteristics of older drivers while driving cars using a gaze analysis device. Methods: The participants included 16 older and 12 middle-aged drivers who drove cars daily. After conducting cognitive and attentional function tests, eye gaze while watching driving videos was measured using an eye tracker. Ten driving videos were prepared. In addition, a total of 34 hazard areas were analyzed. Results: The results of the gaze measurement parameters were statistically compared between the two groups. In the older group, the gaze analysis results indicated that while viewing driving videos, the search for areas close to the car was expanded. In addition, in several hazard areas, we observed a decrease in the number of drivers gazing at the driver, shortened total gazing time, delay in the timing of gazing, and decrease in the number of visits. Conclusions: Older drivers' eye movement is increased; however, it is characterized by gazing at unimportant areas, indicating an inefficient scanning pattern. Although these results do not indicate an obvious decline in driving ability among older drivers, the decline in hazard perception may become apparent in some situations. The data contain underpowered results and require revalidation in larger studies.

关于老年驾驶员观看驾驶电影时目光特征的试点研究。
研究目的本研究旨在利用凝视分析装置,阐明老年驾驶员在驾驶汽车时的凝视特征。研究方法参与者包括 16 名老年驾驶员和 12 名中年驾驶员,他们每天都驾驶汽车。在进行认知和注意力功能测试后,使用眼动仪测量观看驾驶视频时的目光。共准备了 10 个驾驶视频。此外,还对总共 34 个危险区域进行了分析。结果对两组的注视测量参数结果进行了统计比较。老年组的注视分析结果表明,在观看驾驶视频时,对靠近汽车区域的搜索范围有所扩大。此外,在几个危险区域,我们观察到注视驾驶员的人数减少,总注视时间缩短,注视时间延迟,访问次数减少。结论老年驾驶员的眼球运动有所增加,但其特点是注视不重要的区域,这表明其扫描模式效率低下。虽然这些结果并不表明老年驾驶员的驾驶能力明显下降,但在某些情况下,危险感知能力的下降可能会变得明显。这些数据包含的结果效力不足,需要在更大规模的研究中重新验证。
