ABSTRACT

Recently, new digital technologies are frequently used in the industry within the scope of Industry 4.0. Augmented reality (AR) is one of these emerging technologies; it assists users with the help of virtual images on the real display of the work environment. Although AR benefits employees in terms of productivity and quality, it is not precisely known if it has a cognitive effect on the employees. In this study, the effect of AR glasses on the cognitive loads of the employees was investigated. The experiments were carried out on the assembly line of an automobile company. Electroencephalography (EEG) and NASA Task Load Index (NASA-TLX) were used to measure cognitive load. The current and AR-based work procedures were examined comparatively. Also, the difference between the cognitive load on the first and last days of experiments was compared to determine the adaptation status of the employees. The average of the area under the EEG graph as a measure of cognitive load, were 18.96 and 5.24 μV*ms in employees working with and without AR glasses, respectively. NASA-TLX scores of the employees decreased by 10% when they work with AR glasses. So, there was a less cognitive load on employees in the case of using AR glasses. And there was no significant difference between the first and last days of device usage. Hence, AR glasses did not constitute an extra cognitive load from the first day of usage.

增强现实眼镜对汽车行业装配工人认知负荷的影响

摘要

最近,在工业4.0范围内,新的数字技术在该行业中被频繁使用。增强现实(AR)是这些新兴技术之一。它在工作环境的真实显示上通过虚拟图像帮助用户。尽管AR在生产率和质量方面使员工受益,但尚不清楚AR是否会对员工产生认知作用。在这项研究中,研究了AR眼镜对员工认知负荷的影响。实验是在汽车公司的装配线上进行的。脑电图(EEG)和NASA任务负荷指数(NASA-TLX)用于测量认知负荷。比较了当前和基于AR的工作程序。还,比较实验第一天和最后几天的认知负荷之间的差异,以确定员工的适应状况。使用和不使用AR眼镜的员工的EEG图下的平均面积分别为认知负荷的量度,分别为18.96和5.24μV* ms。使用AR眼镜的员工的NASA-TLX分数降低了10%。因此,在使用AR眼镜的情况下,员工的认知负担较小。在使用设备的第一天和最后几天之间没有显着差异。因此,从使用的第一天开始,AR眼镜就不会构成额外的认知负担。分别。使用AR眼镜的员工的NASA-TLX分数降低了10%。因此,在使用AR眼镜的情况下,员工的认知负担较小。在使用设备的第一天和最后一天之间没有显着差异。因此,从使用的第一天开始,AR眼镜就不会构成额外的认知负担。分别。使用AR眼镜的员工的NASA-TLX分数降低了10%。因此,在使用AR眼镜的情况下,员工的认知负担较小。在使用设备的第一天和最后一天之间没有显着差异。因此,从使用的第一天开始,AR眼镜就不会构成额外的认知负担。
