Immersive Virtual Reality (IVR) has the potential to play an important role in increasing environmental literacy by providing individuals the opportunity to experience plausible scenarios of climate change directly. However, there is currently little evidence for the role of IVR, and for specific design features, in increasing environmental self-efficacy. The main objective of this study was to investigate the effects of an IVR intervention on pro-environmental intentions, knowledge, and transfer. A total of 90 middle school students were randomly assigned to two IVR intervention conditions: 1) Awareness, in which students experience the impact of their current food choices on future environmental change; 2) Awareness + Efficacy, in which students had the opportunity to change their food choices and experience the positive impact of this on future environmental change. Both interventions resulted in significant increases in intentions, knowledge, and transfer. However, the Awareness + Efficacy condition resulted in further significant increases in intentions and transfer than the Awareness condition. Finally, mediation analysis showed that the effect of the Awareness + Efficacy condition on intentions and transfer was fully mediated by self-efficacy. These results suggest that allowing students not just to experience climate change but also to see the positive impact of changed personal choices can maximize the effectiveness of IVR on intentions and transfer.

Cybersickness has been one of the main impediments to thewidespread adoption of Virtual Reality for decades. It has beenargued that several factors can influence the occurrence of cybersickness, such as technical factors, interaction design, but also users’ demographics and their perceived presence. Yet, previous studies hadcomparably small sample sizes and demographically homogeneoussamples; comparisons across studies (e.g., regarding demographicfactors) are challenging due to the large variation in the studiedvirtual environments. In this paper, we address these limitations andreport the results of a lab-in-the-field experiment on cybersicknesswith a large and heterogeneous sample of N = 837 participants whonavigated and interacted inside a virtual environment (ages 18–80,M = 29.34, SD = 9.50, 431 males, 400 females, 6 non-binaries andother). We found that female participants and participants with lowerVR experience were more susceptible to experiencing higher levelsof cybersickness. Participants’ cybersickness levels increased withthe time spent in VR and with the distance traversed in the virtualworld up to a point, above which reported levels declined. We alsofound a link between higher levels of cybersickness and reducedhead motion, as well as between lower levels of cybersickness andmore head motion, which led them to explore more of the virtual environment. In contrast to past studies, we did not find any evidencesuggesting an effect of age on cybersickness, nor a negative correlation between presence and cybersickness. Based on our results,we derived a model that achieves a mean classification accuracyof 67.1% for two levels of cybersickness using demographic, userexperience, and behavioral data in VR.

Background Research suggests that head‐mounted displays (HMD) can spark situational interest when they are used to provide science learning experiences that are not possible in traditional classroom settings. However, few studies have investigated the lasting effects of using HMDs in an authentic instructional intervention. Objectives We investigated the effects of a one‐time experience of a virtual field trip to Greenland in a sample of 105 middle school students. Methods Students used either a standard 2D video (video condition; N = 50) or an HMD (HMD condition; N = 55) as part of a six‐lesson educational activity on the topic of climate change. Informed by social cognitive career theory (SCCT), we investigated the effects of the different conditions (video vs. HMD) on the outcomes of self‐efficacy, outcome expectations, interest, and science intentions across three time points. Results and Conclusions The results showed that using the HMD‐based virtual field trip, compared to the video, had a positive immediate effect on self‐efficacy and interest, and total later effects on self‐efficacy, outcome expectations, and interest an average of two and a half weeks after the virtual field trip. The results suggest that HMD‐based virtual field trips can influence self‐efficacy, outcome expectations, and interest more than a video‐based virtual field trip when measured approximately two and a half weeks after the intervention.

This study investigates the impact of an immersive virtual reality (VR) simulation of herd immunity on vaccination intentions and its potential underlying mechanisms. In this preregistered field study, N = 654 participants were randomly assigned to one of the three VR conditions: (1) Gamified Herd Immunity; (2) Gamified Herd Immunity + Empathy (with additional narrative elements); (3) Control (gamified with no vaccination-related content). In the Gamified Herd Immunity simulation, participants embodied a vulnerable person and navigated a wedding venue trying to avoid getting infected. A total of 455 participants with below maximum intentions to take a novel vaccine and without severe cybersickness were analyzed. The Gamified Herd Immunity + Empathy and the Gamified Herd Immunity conditions increased vaccination intentions by 6.68 and 7.06 points on a 0–100 scale, respectively, compared to 1.91 for the Control condition. The Gamified Herd Immunity + Empathy condition enhanced empathy significantly more than the Gamified Herd Immunity condition but did not result in higher vaccination intentions. Experienced presence was related to the change in vaccination intentions. The results suggest that VR vaccination communication can effectively increase vaccination intentions; the effect is not solely due to the technological novelty and does not depend on empathy.

In the metaverse, users will actively engage with 3D content using extended reality (XR). Such XR platforms can stimulate a revolution in health communication, moving from information-based to experience-based content. We outline three major application domains and describe how the XR affordances (presence, agency and embodiment) can improve healthy behaviour by targeting the users’ threat and coping appraisal. We discuss how health communication via XR can help to address long-standing health challenges.
