Immersive Virtual Reality for the Management of Pain in Community-Dwelling Older Adults.
Immersive virtual reality (VR) can provide a high level of engagement and distraction analgesia to address pain. However, community-based applications of this technology for older adults have not been studied. The objective of this study was to examine the applicability and effectiveness of an immersive VR intervention for pain, depression, and quality of life (QOL) in older adults. This pretest–posttest, mixed-methods design included senior center members (n = 12) with pain that interfered with daily functioning. The outcomes included the Numeric Pain Rating Scale, Patient-Reported Outcomes Measurement Information System (PROMIS®) depression scale, World Health Organization Quality of Life Scale Brief Version (WHO QOL-BREF), and open-ended questions. The VR intervention (15- to 45-min sessions, 12 sessions over 6 weeks) was well accepted with no dropouts. There was a significant decrease in pain (p =.002, d = −1.54) with no effect on depression and QOL. There were no adverse effects, and positive perceptions of VR were reported. The 6-week immersive VR intervention was applicable and effective in reducing pain intensity for community-dwelling older adults
MetaSpace II: Object and full-body tracking for interaction and navigation in social VR
MetaSpace II (MS2) is a social Virtual Reality (VR) system where multiple
users can not only see and hear but also interact with each other, grasp and
manipulate objects, walk around in space, and get tactile feedback. MS2 allows
walking in physical space by tracking each user's skeleton in real-time and
allows users to feel by employing passive haptics i.e., when users touch or
manipulate an object in the virtual world, they simultaneously also touch or
manipulate a corresponding object in the physical world. To enable these
elements in VR, MS2 creates a correspondence in spatial layout and object
placement by building the virtual world on top of a 3D scan of the real world.
Through the association between the real and virtual world, users are able to
walk freely while wearing a head-mounted device, avoid obstacles like walls and
furniture, and interact with people and objects. Most current virtual reality
(VR) environments are designed for a single user experience where interactions
with virtual objects are mediated by hand-held input devices or hand gestures.
Additionally, users are only shown a representation of their hands in VR
floating in front of the camera as seen from a first person perspective. We
believe, representing each user as a full-body avatar that is controlled by
natural movements of the person in the real world (see Figure 1d), can greatly
enhance believability and a user's sense immersion in VR.Comment: 10 pages, 9 figures. Video:

Emotional Qualities of VR Space
The emotional response a person has to a living space is predominantly
affected by light, color and texture as space-making elements. In order to
verify whether this phenomenon could be replicated in a simulated environment,
we conducted a user study in a six-sided projected immersive display that
utilized equivalent design attributes of brightness, color and texture in order
to assess to which extent the emotional response in a simulated environment is
affected by the same parameters affecting real environments. Since emotional
response depends upon the context, we evaluated the emotional responses of two
groups of users: inactive (passive) and active (performing a typical daily
activity). The results from the perceptual study generated data from which
design principles for a virtual living space are articulated. Such a space, as
an alternative to expensive built dwellings, could potentially support new,
minimalist lifestyles of occupants, defined as the neo-nomads, aligned with
their work experience in the digital domain through the generation of emotional
experiences of spaces. Data from the experiments confirmed the hypothesis that
perceivable emotional aspects of real-world spaces could be successfully
generated through simulation of design attributes in the virtual space. The
subjective response to the virtual space was consistent with corresponding
responses from real-world color and brightness emotional perception. Our data
could serve the virtual reality (VR) community in its attempt to conceive of
further applications of virtual spaces for well-defined activities.Comment: 12 figure
The power of immersive technologies: a sociopsychological analysis of the relationship between immersive environments, storytelling, sentiment, and the impact on user experience
This dissertation initially focused on exploring the potential of immersive technologies for the distant future. However, the emergence of the COVID-19 virus in late 2019 disrupted the world, causing a pause in many areas. Nevertheless, the butterfly effect of the pandemic spurred the development of immersive technologies, resulting in the rise of the metaverse, web3, non-fungible tokens (NFT), and avatars, which are gaining increasing popularity. The excitement for the metaverse is growing in both academia and industry, leading to new avenues of research, digital marketing, video games, tourism, and social media. This dissertation explores this rapidly emerging technological revolution and its effects on user experience (UX)
Exploring the Use of Virtual Worlds as a Scientific Research Platform: The Meta-Institute for Computational Astrophysics (MICA)
We describe the Meta-Institute for Computational Astrophysics (MICA), the
first professional scientific organization based exclusively in virtual worlds
(VWs). The goals of MICA are to explore the utility of the emerging VR and VWs
technologies for scientific and scholarly work in general, and to facilitate
and accelerate their adoption by the scientific research community. MICA itself
is an experiment in academic and scientific practices enabled by the immersive
VR technologies. We describe the current and planned activities and research
directions of MICA, and offer some thoughts as to what the future developments
in this arena may be.Comment: 15 pages, to appear in the refereed proceedings of "Facets of Virtual

Data Driven Discovery in Astrophysics
We review some aspects of the current state of data-intensive astronomy, its
methods, and some outstanding data analysis challenges. Astronomy is at the
forefront of "big data" science, with exponentially growing data volumes and
data rates, and an ever-increasing complexity, now entering the Petascale
regime. Telescopes and observatories from both ground and space, covering a
full range of wavelengths, feed the data via processing pipelines into
dedicated archives, where they can be accessed for scientific analysis. Most of
the large archives are connected through the Virtual Observatory framework,
that provides interoperability standards and services, and effectively
constitutes a global data grid of astronomy. Making discoveries in this
overabundance of data requires applications of novel, machine learning tools.
We describe some of the recent examples of such applications.Comment: Keynote talk in the proceedings of ESA-ESRIN Conference: Big Data
