    Collaborative View Configurations for Multi-user Interaction with a Wall-size Display
    (The Eurographics Association, 2017) Kim, Hyungon; Kim, Yeongmi; Lee, Gun A.; Billinghurst, Mark; Bartneck, Christoph; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    This paper explores the effects of different collaborative view configuration on face-to-face collaboration using a wall-size display and the relationship between view configuration and multi-user interaction. Three different view configurations (shared view, split screen, and split screen with navigation information) for multi-user collaboration with a wall-size display were introduced and evaluated in a user study. From the experiment results, several insights for designing a virtual environment with a wall-size display were discussed. The shared view configuration does not disturb collaboration despite control conflict and can provide an effective collaboration. The split screen view configuration can provide independent collaboration while it can take users' attention. The navigation information can reduce the interaction required for the navigational task while an overall interaction performance may not increase.

    Improving Collaboration in Augmented Video Conference using Mutually Shared Gaze
    (The Eurographics Association, 2017) Lee, Gun A.; Kim, Seungwon; Lee, Youngho; Dey, Arindam; Piumsomboon, Thammathip; Norman, Mitchell; Billinghurst, Mark; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    To improve remote collaboration in video conferencing systems, researchers have been investigating augmenting visual cues onto a shared live video stream. In such systems, a person wearing a head-mounted display (HMD) and camera can share her view of the surrounding real-world with a remote collaborator to receive assistance on a real-world task. While this concept of augmented video conferencing (AVC) has been actively investigated, there has been little research on how sharing gaze cues might affect the collaboration in video conferencing. This paper investigates how sharing gaze in both directions between a local worker and remote helper in an AVC system affects the collaboration and communication. Using a prototype AVC system that shares the eye gaze of both users, we conducted a user study that compares four conditions with different combinations of eye gaze sharing between the two users. The results showed that sharing each other's gaze significantly improved collaboration and communication.

    Sharing Gaze for Remote Instruction
    (The Eurographics Association, 2017) Barathan, Sathya; Lee, Gun A.; Billinghurst, Mark; Lindeman, Robert W.; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    In this paper, we report on how sharing gaze cues can assist remote instruction. A person wearing a head-mounted display and camera can share his or her view with a remote collaborator and get assistance on completing a real-world task. This configuration has been extensively studied in the past, but there has been little research on how the addition of sharing gaze cues might affect the collaboration. This paper reports on a user study exploring how sharing the gaze of a remote expert affects the quality of collaboration over a head-worn video conferencing link. The results showed that the users performed faster when the local workers were aware of their remote collaborator's gaze, and the remote experts were in favour of shared gaze cues because of the ease-of-use and improved communication.
