  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.
