这篇系统的文献综述介绍了3D环境中眼运动数据的3D可视化技术和分析工具的最新发展。随着向大众市场推出负担得起的非侵入式眼动追踪解决方案,现在越来越有可能访问用户\'凝视。因此,由于趋势是将视线跟踪作为新技术解决方案的一部分,因此在使用头戴式显示器的虚拟环境中采用眼睛跟踪有望增加。本文提出的系统文献综述是使用Scopus数据库(使用2017年至2022年5月17日)进行的,经过分析,导致包含15种与3D虚拟场景的眼动跟踪可视化技术相关的最新出版物。首先,本文简要介绍了眼动跟踪和传统二维可视化技术的基础。作为背景,我们还列出了在之前的综述中确定的早期3D眼动追踪可视化技术.接下来,系统的文献综述介绍了用于获取所包含的论文的方法,并在眼动追踪技术方面进行了描述,观察到的刺激,应用程序上下文,和3D凝视可视化技术的类型。然后我们讨论总体发现,包括机会,挑战,趋势,并提出未来方向的想法。总体而言,结果表明,沉浸式虚拟环境中的眼动跟踪正在兴起,需要更多的研究和开发来创建新颖和改进的3D凝视分析技术解决方案。
This systematic literature
review presents an update on developments in 3D visualization techniques and analysis tools for eye movement data in 3D environments. With the introduction of affordable and non-intrusive eye-tracking solutions to the mass market, access to users\'
gaze is now increasingly possible. As a result, the adoption of eye-tracking in virtual environments using head-mounted displays is expected to increase since the trend is to incorporate
gaze tracking as part of new technical solutions. The systematic literature
review presented in this paper was conducted using the Scopus database (using the period 2017 to 17th of May 2022), which after analysis, resulted in the inclusion of 15 recent publications with relevance in eye-tracking visualization techniques for 3D virtual scenes. First, this paper briefly describes the foundations of eye-tracking and traditional 2D visualization techniques. As background, we also list earlier 3D eye-tracking visualization techniques identified in a previous review. Next, the systematic literature
review presents the method used to acquire the included papers and a description of these in terms of eye-tracking technology, observed stimuli, application context, and type of 3D gaze visualization techniques. We then discuss the overall findings, including opportunities, challenges, trends, and present ideas for future directions. Overall the results show that eye-tracking in immersive virtual environments is on the rise and that more research and developments are needed to create novel and improved technical solutions for 3D gaze analysis.
