    Spatial Multi-Presence System to Increase Security Awareness for Remote Collaboration in an Extended Reality Environment

    Jun Lee1, Hyun Kwon2,*

    Intelligent Automation & Soft Computing, Vol.37, No.1, pp. 369-384, 2023, DOI:10.32604/iasc.2023.036052

    Abstract Enhancing the sense of presence of participants is an important issue in terms of security awareness for remote collaboration in extended reality. However, conventional methods are insufficient to be aware of remote situations and to search for and control remote workspaces. This study proposes a spatial multi-presence system that simultaneously provides multiple spaces while rapidly exploring these spaces as users perform collaborative work in an extended reality environment. The proposed system provides methods for arranging and manipulating remote and personal spaces by creating an annular screen that is invisible to the user. The user can… More >

    View Types and Visual Communication Cues for Remote Collaboration

    Seungwon Kim1, Weidong Huang2, Chi-Min Oh3, Gun Lee4, Mark Billinghurst4, Sang-Joon Lee5,*

    CMC-Computers, Materials & Continua, Vol.74, No.2, pp. 4363-4379, 2023, DOI:10.32604/cmc.2023.034209

    Abstract Over the last several years, remote collaboration has been getting more attention in the research community because of the COVID-19 pandemic. In previous studies, researchers have investigated the effect of adding visual communication cues or shared views in collaboration, but there has not been any previous study exploring the influence between them. In this paper, we investigate the influence of view types on the use of visual communication cues. We compared the use of the three visual cues (hand gesture, a pointer with hand gesture, and sketches with hand gesture) across two view types (dependent… More >
