Chasing Metaverses: Reflecting on Existing Literature to Understand the Business Value of Metaverses

Metaverses refer to immersive virtual worlds in which people, places, and things of the physical world are represented by their digital representations. The wide adoption of metaverses is expected to widely disrupt the way we interact in the virtual world by elevating our online interactive experiences and bringing a plethora of implications for businesses. Following a structured literature review of related research published in the last decade, we shed light on our current understanding of metaverses and reflect on the potentially transformative value of metaverses for businesses in the near future. We draw on an established research framework to organize the insights of existing literature across different levels of analysis and activities’ purpose. Through this analysis, we reveal eight propositions on the changes brought by the use of metaverses and identify a number of open questions which could serve as future research avenues.publishedVersionPaid Open Acces

Identifying immersive environments’ most relevant research topics: an instrument to query researchers and practitioners

This paper provides an instrument for ascertaining researchers’ perspectives on the relative relevance of technological challenges facing immersive environments in view of their adoption in learning contexts, along three dimensions: access, content production, and deployment. It described its theoretical grounding and expert-review process, from a set of previously-identified challenges and expert feedback cycles. The paper details the motivation, setup, and methods employed, as well as the issues detected in the cycles and how they were addressed while developing the instrument. As a research instrument, it aims to be employed across diverse communities of research and practice, helping direct research efforts and hence contribute to wider use of immersive environments in learning, and possibly contribute towards the development of news and more adequate systems.The work presented herein has been partially funded under the European H2020 program H2020-ICT-2015, BEACONING project, grant agreement nr. 687676.info:eu-repo/semantics/publishedVersio

Empowering Users to Create Augmented Reality-Based Solutions – Deriving Design Principles for No-Code AR Authoring Tools

Grounded on an experimental study with 18 participants, we derive 15 design principles for no-code AR authoring tools in an organizational setting. The study consists of two distinct treatments that aim to augment lightweight processes with AR. The outcomes are two interactive tutorials utilizing AR instructions. Following the no-code approach, the participants were empowered to create relevant AR content using a reduced interface and no need for advanced configurations or coding. The study thus combines two research streams with the aim of better understanding mechanisms for AR use in a professional context. As prior work has shown, despite the potential benefits, the adoption of AR authoring tools is limited because ramping up AR to productive use is heavily dependent on consulting and custom software solutions. Our novel approach bears the potential to broaden application domains and empower professionals to apply AR

Coping with the inheritance of COVID-19: the role of new interactive technologies to enhance user experience in different contexts of use

The COVID-19 pandemic has upset the habits of people and various sectors of society, including training, entertainment, and retail. These sectors have been forced to adapt to abnormal situations such as social distancing, remote work, and online entertainment. The pandemic has significantly transformed the training field, leading to the closure of many in-person instruction centers and a shift toward online education courses, which can be less effective. In addition, the entertainment industry has been heavily transformed by social distancing, resulting in the cancellation of many live events and the closure of several cinemas. This has increased demand for online entertainment options, such as streaming services and virtual events. Finally, the restrictions imposed by the COVID-19 pandemic substantially impacted physical stores and fairs, suspending exhibitions for more than two years. This has further driven consumers to rely on e-commerce to fulfill their purchasing and companies to increasingly take advantage of new technologies such as augmented reality. In this suddenly disrupted scenario, new technologies have the potential to fill the gap generated by the pandemic, functioning as an interactive bridge to connect people. This Ph.D. thesis explored the potential of interactive technologies in mitigating the challenges posed by the COVID-19 pandemic in various contexts of use in the above-mentioned areas. Specifically, three lines of research were investigated by conducting different studies using a mixed approach in the Human-Computer Interaction field. The first research line focused on the study of immersive virtual reality training, with a particular interest in flood emergencies, a growing phenomenon. The goal was to implement engaging and efficient training for citizens that live near rivers through a human-centric design approach. The second line of research explored innovative ways to improve social interaction and collaboration in the entertainment sector, highlighting guidelines for the design of shared streaming experiences. In particular, three different communication modalities were studied during group viewing of an interactive film on a streaming platform. Finally, the third research line focused on the retail sector. On the one hand, the focus consisted of understanding which aspects of the 3D web and AR technology are helpful for supporting small businesses and trade fairs. On the other hand, the focus was to investigate how to support consumers during an AR shopping experience when interacting with 3D virtual products of different sizes. Overall, this project provides suggestions and guidelines for designing systems that can both increasingly connect people at a distance and offer new hybrid worlds. In addition, this project expands state-of-the-art related to interactive technologies and offers generalizable results outside the crisis created by COVID-19. These technologies, now increasingly integrated into everyday life, can be a tool for empowerment and resilience, improving people's lives.The COVID-19 pandemic has upset the habits of people and various sectors of society, including training, entertainment, and retail.

How to design for persistence and retention in MOOCs?

Design of educational interventions is typically carried out following a design cycle involving phases of investigation, conceptualization, prototyping, implementation, execution and evaluation. This cycle can be applied at different levels of granularity e.g. learning activity, module, course or programme. In this paper we consider an aspect of learner behavior that can be critical to the success of many MOOCs i.e. their persistence to study, and the related theme of learner retention. We reflect on the impact that consideration of these can have on design decisions at different stages in the design cycle with the aim of en-hancing MOOC design in relation to learner persistence and retention, with particular attention to the European context
