A state of the art and scoping review of embodied information behavior in shared, co-present extended reality experiences

We present a state of the art and scoping review of the literature to examine embodied information behaviors, as reflected in shared gaze interactions, within co-present extended reality experiences. Recent proliferation of consumer-grade head-mounted XR displays, situated at multiple points along the Reality-Virtuality Continuum, has increased their application in social, collaborative, and analytical scenarios that utilize data and information at multiple scales. Shared gaze represents a modality for synchronous interaction in these scenarios, yet there is a lack of understanding of the implementation of shared eye gaze within co-present extended reality contexts. We use gaze behaviors as a proxy to examine embodied information behaviors. This review examines the application of eye tracking technology to facilitate interaction in multiuser XR by sharing a user’s gaze, identifies salient themes within existing research since 2013 in this context, and identifies patterns within these themes relevant to embodied information behavior in XR. We review a corpus of 50 research papers that investigate the application of shared gaze and gaze tracking in XR generated using the SALSA framework and searches in multiple databases. The publications were reviewed for study characteristics, technology types, use scenarios, and task types. We construct a state-of-the field and highlight opportunities for innovation and challenges for future research directions.

我们对文献进行了一次最前沿的范围综述，以研究在共同在场的扩展现实体验中体现在共享注视交互中的具身信息行为。近期，处于现实 - 虚拟连续体多个点上的消费级头戴式XR显示器的大量涌现，增加了它们在利用多尺度数据和信息的社交、协作和分析场景中的应用。共享注视代表了这些场景中同步交互的一种方式，但对于在共同在场的扩展现实环境中共享眼神注视的实施缺乏了解。我们将注视行为作为一种替代来研究具身信息行为。本综述研究了眼动追踪技术通过共享用户注视来促进多用户XR交互的应用，确定了2013年以来在此背景下现有研究中的突出主题，并确定了这些主题中与XR中的具身信息行为相关的模式。我们回顾了50篇研究论文的语料库，这些论文使用SALSA框架并在多个数据库中搜索，研究了共享注视和注视追踪在XR中的应用。对这些出版物从研究特征、技术类型、使用场景和任务类型方面进行了综述。我们构建了该领域的现状，并强调了创新机会以及未来研究方向面临的挑战。
