Abstract Remote collaboration has been studied for more than two decades and now there is the possibilities for new types of collaboration with the recent advances in immersive technologies such as Virtual, Augmented, Mixed Reality (VR/AR/MR). However, despite the increasing research interest in remote collaboration study with VR/AR/MR technologies, there is still a lack of academic venues specifically focusing on VR/AR/MR remote collaboration research. This special issue provides high-quality papers on the topic of remote collaboration research and increases visibility of this timely interesting and important research area. We particularly focus on three research aspects in remote collaboration: (1) use of multimodal communication cues, (2) awareness of the task space, and (3) human factors understanding. In this editorial, we first describe five essential factors for remote collaboration: task, local user, remote user, communication, and tool/interface, and then summarize a brief history of the research areas. We also cover the feature papers accepted in this issue, which introduce novel multimodal interfaces for remote collaboration and the effects on task performance and perceptual factors. Finally, we discuss some potential future research directions while concluding the editorial. Keywords Remote Collaboration · Communication Cues · Multimodal Interfaces · Mixed Reality
1 Introduction While our society and culture have been evolving, we have continuously developed skills to work/collaborate remotely with other people [46]. Here, collaboration is multi-person activities to achieve a common goal [12], and could be categorized into two sectors according to the collaborators’ locations—e.g., whether they stay in the same place or not. People usually have better collaboration when staying in the same place rather than when they are in remote places [22]. People intuitively and immediately shares

social/communication cues in co-located collaboration, but this is not always available in remote collaboration, especially with conventional remote communication technologies, e.g., telephone and videoconferencing tools. Thanks to the recent advances in immersive technologies with multimodal interfaces, such as Virtual, Augmented, and Mixed Reality (VR/AR/MR) with support for gesture and gaze input, we encounter a new era of technologically enhanced remote collaboration with unique opportunities and challenges [19,37]. In remote collaboration studies, AR/VR/MR technologies have b
