摘要

本研究调查了与视频会议系统相比使用远程呈现系统的有效性,以及与使用一台摄像机相比使用两台摄像机进行远程物理治疗的有效性。我们使用Telegie作为我们的远程呈现系统,使用户可以通过VR耳机看到RGBD相机拍摄的3D环境。由于远程呈现和第二个摄像头的加入都为用户提供了额外的空间信息,我们在远程物理治疗的相关背景下研究了这种可供性。我们在不同时区进行的二元研究将11名物理治疗师与76名参与者配对,他们在远程会话中扮演患者的角色。我们的定量问卷数据和对治疗师的定性访谈揭示了几个重要的发现。首先,在控制了参与者之间的个体差异后,使用两台相机对治疗师的物理治疗评估分数有轻微的积极影响。其次,患者的空间能力是治疗师评估的有力预测因素。第三,远程通信系统的视频清晰度很重要。基于我们的发现,我们对未来远程通信中远程呈现系统的使用提出了一些建议和见解。

An Evaluation Study of 2D and 3D Teleconferencing for Remote Physical Therapy
The present research investigates the effectiveness of using a telepresence system compared to a video conferencing system and the effectiveness of using two cameras compared to one camera for remote physical therapy. We used Telegie as our telepresence system, which allowed users to see an environment captured with RGBD cameras in 3D through a VR headset. Since both telepresence and the inclusion of a second camera provide users with additional spatial information, we examined this affordance within the relevant context of remote physical therapy. Our dyadic study across different time zones paired 11 physical therapists with 76 participants who took on the role of patients for a remote session. Our quantitative questionnaire data and qualitative interviews with therapists revealed several important findings. First, after controlling for individual differences among participants, using two cameras had a marginally significant positive effect on physical therapy assessment scores from therapists. Second, the spatial ability of patients was a strong predictor of therapist assessment. And third, the video clarity of remote communication systems mattered. Based on our findings, we offer several suggestions and insights towards the future use of telepresence systems for remote communication.
