“…Conversely, hardware solutions aim to optically locate a camera in front of the user and take actual frontal images using space‐division or time‐division systems. In space‐division systems, techniques employing a half‐silvered mirror and virtually bringing a camera behind the display are well known 22 . Such a system installs a slanted half‐silvered mirror in front of a display and a camera above or below the mirror.…”

Video‐mediated communication systems are generally used to enable face‐to‐face‐like communication between people in distant locations. However, in terms of social telepresence, video communication systems are generally inferior to actual face‐to‐face communication, which is a long‐standing challenge for online communication systems. Multiple studies have reported that several specific components, such as the resolution of the transmitted video and the width of the visual field, affect social telepresence separately. However, methods have not been established to comprehensively evaluate the sense of social telepresence provided by video communication systems, that is, integrated multiple component systems with various specifications. In this study, employing a regression analysis based on subjective evaluation results, we establish a new method to predict the sense of social telepresence based on the specifications of some system components. Using this formulation, it is clear that realizing eye contact and life‐size scaling make relatively large contributions to enhancing social telepresence. Finally, we develop a prototype system realizing eye contact and life‐size scaling and perform additional subjective evaluations to reconfirm the effectiveness of these components to enhance the sense of social telepresence in real‐time communication.

“…There are two existing approaches for obtaining frontal images to achieve eye contact: a software (SW) approach [4][5][6] , which synthesizes virtual frontal images through image processing, and a hardware (HW) approach [2,[7][8][9] , which obtains optically correct frontal images using fast response projectors and liquid crystal screens or half mirrors. Compared with the SW approach, the HW approach has the advantage that the gap between the user's eye gaze direction and the camera's optical axis direction is small, even in case the display area is large, so natural frontal images can be obtained.…”

In hub-satellite collaboration using video, interpreting gaze direction is critical for communication between hub coworkers sitting around a table and their remote satellite colleague. However, 2D video distorts images and makes this interpretation inaccurate. We present GazeLens, a video conferencing system that improves hub coworkers' ability to interpret the satellite worker's gaze. A 360 • camera captures the hub coworkers and a ceiling camera captures artifacts on the hub table. The system combines these two video feeds in an interface. Lens widgets strategically guide the satellite worker's attention toward specific areas of her/his screen allow hub coworkers to clearly interpret her/his gaze direction. Our evaluation shows that GazeLens (1) increases hub coworkers' overall gaze interpretation accuracy by 25.8% in comparison to a conventional video conferencing system, (2) especially for physical artifacts on the hub table, and (3) improves hub coworkers' ability to distinguish between gazes toward people and artifacts. We discuss how screen space can be leveraged to improve gaze interpretation.
