“…Piumsomboon et al [22] proposed a prototype multiscale MR collaboration system that supports two collaboration modes, conventional scale collaboration (CSC) and giant-micro collaboration (GMC), where local users can hold a camera and change the shared view for transmission to remote users. Lee et al [5] evaluated viewsharing techniques in a one-to-many collaborative MR environment, where a camera is placed on the local user's AR HMD to capture the workspace for transmission to the remote user, who observes it using a VR HMD. Rhee et al [4] proposed a remote collaboration platform that transmits a remote VR traveler into a mixed-reality collaborative space (MRC space) to interact with an AR host in another physical space, where a 360 • camera in a fixed location in the physical space provides a realistic representation of the environment for the remote user.…”

“…In this type of collaboration, remote users observe the local environment through virtual reality (VR) head-mounted displays (HMDs) and collaborate with local users wearing AR HMDs [1][2][3]. In traditional mixed-reality remote collaboration, the video capture device is typically placed in a fixed position in the local environment [4] or on a local user's HMD [5], providing a fixed perspective or the local user's first-person view of the local environment, and remote users cannot actively and freely switch views. In recent research on remote presentations, researchers have mainly deployed video capture devices on wheeled robots [6][7][8] or drones [9,10], allowing remote users to move the viewing perspective by operating these devices.…”

In mixed-reality (MR) telecollaboration, the local environment is remotely presented to a remote user wearing a virtual reality (VR) head-mounted display (HMD) via a video capture device. However, remote users frequently face challenges in naturally and actively manipulating their viewpoints. In this paper, we propose a telepresence system with viewpoint control, which involves a robotic arm equipped with a stereo camera in the local environment. This system enables remote users to actively and flexibly observe the local environment by moving their heads to manipulate the robotic arm. Additionally, to solve the problem of the limited field of view of the stereo camera and limited movement range of the robotic arm, we propose a 3D reconstruction method combined with a stereo video field-of-view enhancement technique to guide remote users to move within the movement range of the robotic arm and provide them with a larger range of local environment perception. Finally, a mixed-reality telecollaboration prototype was built, and two user studies were conducted to evaluate the overall system. User study A evaluated the interaction efficiency, system usability, workload, copresence, and user satisfaction of our system from the remote user’s perspective, and the results showed that our system can effectively improve the interaction efficiency while achieving a better user experience than two traditional view-sharing techniques based on 360 video and based on the local user’s first-person view. User study B evaluated our MR telecollaboration system prototype from both the remote-user side and the local-user side as a whole, providing directions and suggestions for the subsequent design and improvement of our mixed-reality telecollaboration system.

This paper proposes a promotion system of social participation for people who have difficulty in going out with mixed reality collaboration technique. More than one billion population in the world are tortured by disabilities, and a majority of them have difficulties in social participation due to the unsatisfied transportation demanding. Therefore, in this paper, we propose to use a remote collaboration system based on mixed reality to help people with disabilities to join in social activities. Specifically, our system employs a pair of VR and AR HMDs as well as a 360 • camera to create a virtual environment, where physically separated users can interact with each other immersively. Furthermore, we also equip our system with a branch of functions which can further facilitate the communications. In order to test our system, we also design a remote shopping scenario to simulate the condition where people with disabilities want to go shopping at home. The user study shows that our system can satisfy most requirements without triggering obvious discomfort.
