Abstract

The COVID-19 pandemic created the need to raise awareness about airborne disease transmission via respiratory particles. Immersive Augmented Reality (AR) could increase Situation Awareness (SA) about this invisible phenomenon. Teachers play an important role in handling health emergencies by providing health literacy and promoting protective behaviors and thus could benefit from this technology. The aim of this study was threefold: (a) to develop an immersive educational AR application that creates awareness about airborne disease transmission, (b) to empirically evaluate its effectiveness in terms of SA and user experience among teachers and (c) to investigate design issues and more specifically the role of color of the visualized respiratory particles. Two versions of the application were created for Magic Leap 1 AR glasses representing respiratory particles as red or blue spherical shapes. An empirical study with forty-eight educators was carried out to measure SA and user experience in terms of presence, simulator sickness, workload, and satisfaction. The results showed that the application created high levels of overall SA for both colors. Presence and satisfaction were very high regardless of color and positively correlated. Simulator sickness and workload were low regardless of color and were not correlated with SA or presence. Participants’ comments confirmed their high levels of presence, SA and satisfaction. In terms of gender differences, women scored slightly higher in SA but were more vulnerable to simulator sickness. Overall, results imply that immersive AR can create high SA about airborne disease transmission while providing a positive experience.
基于沉浸式增强现实的教师对空气传播疾病的体验与态势感知
COVID-19大流行使人们有必要提高对通过呼吸道颗粒传播的空气传播疾病的认识。沉浸式增强现实(AR)可以提高对这种无形现象的态势感知(SA)。教师通过提供卫生知识和促进保护行为,在处理突发卫生事件方面发挥重要作用,因此可以从这项技术中受益。本研究的目的有三个:(a)开发一种沉浸式教育AR应用程序,以提高对空气传播疾病的认识,(b)根据SA和教师的用户体验经验评估其有效性,(c)调查设计问题,更具体地说,是可视化呼吸颗粒颜色的作用。为Magic Leap 1 AR眼镜创建了两个版本的应用程序,将呼吸颗粒表示为红色或蓝色球形。对48名教育工作者进行了一项实证研究,以衡量SA和用户体验的存在感、模拟器疾病、工作量和满意度。结果表明,该应用程序对两种颜色都产生了高水平的总体SA。无论肤色,在场感和满意度都非常高,且呈正相关。无论肤色如何,模拟器病和工作量都很低,与SA或存在无关。参与者的评论证实了他们高水平的存在感、SA和满意度。在性别差异方面,女性的SA得分略高,但更容易患模拟器病。总体而言,研究结果表明,沉浸式AR可以在提供积极体验的同时,对空气传播疾病产生高SA。
