“…By supporting stereoscopic 3D and motion parallax, the system is capable of conveying accurate hand pointing gestures and body poses. Edelmann et al focus on the interaction with digital content [7]. The system features a stereo camera setup behind a semi-transparent holographic multi-touch screen to capture the remote scene.…”

This paper presents 3D-Board, a digital whiteboard capable of capturing life-sized virtual embodiments of geographically distributed users. When using large-scale screens for remote collaboration, awareness for the distributed users' gestures and actions is of particular importance. Our work adds to the literature on remote collaborative workspaces, it facilitates intuitive remote collaboration on large scale interactive whiteboards by preserving awareness of the full-body pose and gestures of the remote collaborator. By blending the front-facing 3D embodiment of a remote collaborator with the shared workspace, an illusion is created as if the observer was looking through the transparent whiteboard into the remote user's room. The system was tested and verified in a usability assessment, showing that 3D-Board significantly improves the effectiveness of remote collaboration on a large interactive surface.

“…A variety of paradigms have been achieved, including a remote user who appears in a local location [36], a remote space appearing to expand beyond the local environment [4,37], and a local user who is immersed in a remote area [38]. High-speed data transmission and real-time visualization of transmitted data are essential in a 3D telepresence system to transmit the 3D representation of the user or an environment and to ensure the interaction system is to provide immediate feedback [39]. Communication technology has developed rapidly with advancements in imaging and display technologies [40].…”

Real-time three-dimensional (3D) reconstruction of real-world environments has many significant applications in various fields, including telepresence technology. When depth sensors, such as those from Microsoft’s Kinect series, are introduced simultaneously and become widely available, a new generation of telepresence systems can be developed by combining a real-time 3D reconstruction method with these new technologies. This combination enables users to engage with a remote person while remaining in their local area, as well as control remote devices while viewing their 3D virtual representation. There are numerous applications in which having a telepresence experience could be beneficial, including remote collaboration and entertainment, as well as education, advertising, and rehabilitation. The purpose of this systematic literature review is to analyze the recent advances in 3D reconstruction methods for telepresence systems and the significant related work in this field. Next, we determine the input data and the technological device employed to acquire the input data, which will be utilized in the 3D reconstruction process. The methods of 3D reconstruction implemented in the telepresence system as well as the evaluation of the system, have been extracted and assessed from the included studies. Through the analysis and summarization of many dimensions, we discussed the input data used for the 3D reconstruction method, the real-time 3D reconstruction methods implemented in the telepresence system, and how to evaluate the system. We conclude that real-time 3D reconstruction methods for telepresence systems have progressively improved over the years in conjunction with the advancement of machines and devices such as Red Green Blue-Depth (RGB-D) cameras and Graphics Processing Unit (GPU).

In product design education, identifying proportion and manipulating proportional relationships are important practices in form-giving training. However, using conventional 2D displays with monocular depth cues to train students with different spatial abilities remains a great challenge. Although, some literature has indicated that stereoscopic 3D (S3D) displays were helpful for depth-related tasks, whether S3D is helpful for proportion estimation is an open question. Therefore, the objective of this research was to study whether using S3D for design department students could assist them in improving their ability to interpret the proportions of products. The independent variables of the experiment included spatial ability, task complexity, and display mode. Spatial ability was a between-subject variable. Students aged 20-25 years were recruited as participants and were categorized into high-, moderate-, and low-performance groups depending on their score on a spatial ability scale. Task complexity and display mode were within-subject variables. In the experiment, three chair styles were used as samples. Digital models of three chairs with distinct proportions were displayed in two conditions: 2D mode with monocular depth cues and S3D mode. Participants were asked to compare the proportions of a physical chair and three digital chairs and then select the digital chair with the correct proportions in the 2D and S3D modes. The dependent variable were the score of selecting the 3D digital models with correct proportions compared to the physical objects. The result indicated that students could perceive proportions more accurately in the S3D mode than in the 2D mode. In particular, when using S3D, participants with low spatial ability demonstrated overall performance that was equal to that of participants with high spatial ability.
