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.

评估和制定视频介导的通信系统中的社交网真感：目光交流对增强社交网真的贡献

视频介导的通信系统通常用于在遥远的地方实现人与人之间的面对面交流。但是，就社交网真而言，视频通信系统通常不如实际的面对面通信，这是在线通信系统的长期挑战。多项研究报告说，几个特定的​​组件（例如，传输的视频的分辨率和视野的宽度）分别影响社交远程呈现。然而，尚未建立用于全面评估由视频通信系统（即，具有各种规格的集成多组件系统）提供的社交网真感的方法。在这项研究中，基于主观评估结果进行回归分析，我们基于一些系统组件的规范，建立了一种预测社交网真感的新方法。使用这种表述，很明显，实现眼神交流和按比例缩放真人秀对增强社交网真做出了较大贡献。最后，我们开发了一个原型系统，实现了眼神交流和真实尺寸的缩放，并执行了其他主观评估，以重新确认这些组件的有效性，从而增强了实时通信中的社交网真感。
