This paper analyzes the joint assessment of quality, spatial and social presence, empathy, attitude, and attention in three conditions: (A)visualizing and rating the quality of contents in a Head-Mounted Display (HMD), (B)visualizing the contents in an HMD,and (C)visualizing the contents in an HMD where participants can see their hands and take notes. The experiment simulates an immersive communication where participants attend conversations of different genres and from different acquisition perspectives in the context of international experiences. Video quality is evaluated with Single-Stimulus Discrete Quality Evaluation (SSDQE) methodology. Spatial and social presence are evaluated with questionnaires adapted from the literature. Initial empathy is assessed with Interpersonal Reactivity Index(IRI) and a questionnaire is designed to evaluate attitude. Attention is evaluated with 3 questions that had pass/fail answers. 54 participants were evenly distributed among A, B, and C conditions taking into account their international experience backgrounds, obtaining a diverse sample of participants. The results from the subjective test validate the proposed methodology in VR communications, showing that video quality experiments can be adapted to conditions imposed by experiments focused on the evaluation of socioemotional features in terms of contents of long-duration, actor and observer acquisition perspectives, and genre. In addition, the positive results related to the sense of presence imply that technology can be relevant in the analyzed use case. The acquisition perspective greatly influences social presence and all the contents have a positive impact on all participants on their attitude towards international experiences. The annotated dataset, Student Experiences Around the World dataset (SEAW-dataset), obtained from the experiment is made publicly available.

评估社会VR中的质量，存在，同理心，态度和注意力的方法：国际经验用例

本文在以下三个条件下分析了对质量，空间和社会存在，同情心，态度和注意力的联合评估：（A）可视化和评定头戴式显示器（HMD）中内容的质量，（B）可视化内容（C）可视化HMD中的内容，使参与者可以看到他们的手并做笔记。该实验模拟了一种身临其境的交流方式，参与者可以在国际经验的背景下参加不同体裁的对话，并从不同的习得角度参与对话。视频质量通过单激励离散质量评估（SSDQE）方法进行评估。空间和社会影响力可以通过改编自文献的问卷进行评估。最初的同理心通过人际反应指数（IRI）进行评估，并设计问卷调查以评估态度。通过3个具有通过/失败答案的问题对注意力进行评估。考虑到他们的国际经验背景，将54位参与者平均分配到A，B和C条件中，从而获得了不同的参与者样本。主观测试的结果验证了VR通信中的拟议方法，表明视频质量实验可以适应长期关注内容，演员和观察者获取视角以及侧重于评估社会情感特征的实验所施加的条件，并且类型。此外，与存在感相关的积极结果表明，技术在所分析的用例中可能是相关的。收购视角极大地影响着社会存在，所有内容对所有参与者对国际经验的态度都产生了积极影响。从实验获得的带注释的数据集“世界各地的学生体验”数据集（SEAW数据集）已公开可用。
