Summary: In this experiment, we investigated the effects of augmented reality (AR) and how these effects could be influenced by privacy perceptions. Using a between-subject experimental design with 114 Korean adults, we found that AR had a significant impact on perceived ease of use but not on perceived usefulness. However, the positive effect of AR on perceived usefulness was weakened when participants were primed with privacy concerns. The results also supported a moderated mediation model, showing that the indirect effect of AR on app usage intention via perceived usefulness was moderated by privacy priming.

Summary: This study explored the application of immersive virtual reality (VR) in food product evaluation by comparing the effects of congruent and incongruent VR contexts on consumer acceptance. The results showed that immersive VR induced positive sensations of presence and engagement, and congruent contexts were more effective in enhancing desire and liking for the food product. This highlights the importance of VR as a tool for evaluating contextual factors in new product development.

Summary: The perception behavior of consumers plays a vital role in determining the importance given to a product in the market. Immersive technologies such as virtual, augmented, and mixed reality have been developed to understand and analyze consumer behavior. In the field of food selection, these technologies can be used to develop new products, understand real-time shopping behavior, and study the influence of emotions on product selection.

Summary: This study examined the use of virtual reality (VR) and augmented reality (AR) virtual tourism to address issues in the senior tourism market. The researchers investigated the characteristics of VR and AR in revitalizing senior tourism and their impact on older adults' experience, perceived advantage, enjoyment, and reuse intention. Mixed methods were used to develop four attributes of VR and AR for senior tourism and analyze their effects on emotional and behavioral responses of older adults. The findings revealed significant relationships between the variables, providing useful insights for using VR and AR to effectively activate senior tourism.

Summary: Heuristic evaluation is widely used for assessing augmented reality systems, with the focus often on performance metrics rather than the overall user experience. This study compared the use of specific and general heuristics for evaluating different interactive levels of an AR application. Participants' personality traits and prior experience, along with usability data, were collected and analyzed. The results showed that the use of specific heuristics led to a larger number of unique usability problems, while general heuristics resulted in higher overall satisfaction. Additionally, the more interactive version of the AR application was perceived as more challenging to evaluate, regardless of the heuristics used.

Summary: This study proposes a Mobile Augmented Reality Acceptance Model (MARAM) to examine the factors influencing teachers' intention to use Mobile Augmented Reality (MAR) in their teaching. The MARAM incorporates perceived relative advantage, perceived enjoyment, facilitating conditions, and mobile self-efficacy in addition to the existing Technology Acceptance Model (TAM). Data were collected from pre-service and in-service teachers who developed MAR applications and completed a questionnaire. The results show that intention is influenced by attitude, perceived usefulness, and facilitating conditions, while attitude is influenced by perceived enjoyment and perceived usefulness.

Summary: This study explores the application of augmented reality (AR) and virtual reality (VR) in tourism from an integrated perspective and confirms the importance of presence as the core feature of AR/VR in tourism. The study findings show that presence has both direct and indirect effects on tourism experience through the mediators of value perception and psychological response. Additionally, the study identifies simulation type and social interaction as positive moderators of the effect of presence on tourism experience, while prior visitation has a negative moderating effect.

Summary: Augmented reality technology has been adopted by the food and beverage sector to improve customer experience. Research shows that by visually simulating the consumption of food items in real-time environments, AR increases consumers' desire for the products and their likelihood to make a purchase. This increased mental simulation is influenced by the consumers' personal relevance of the food items.

The results showed that home cooking frequency and self-perceived cooking skills were positively associated with SWFL, while commensality was positively associated with SWFL but not with subjective well-being. Loneliness was negatively associated with SWFL and subjective well-being. Satisfaction with food-related life and subjective health status were positively associated with subjective well-being.

Summary: Natural and electrical lighting have received attention in hospital environments for their benefits to hospital staffs, shift workers, and patients. This study investigated the satisfaction and perception of a circadian lighting system (CLS) among staff in a newly built hospital. The results showed that the CLS was highly satisfactory and easier to use and adjust compared to the pre-existing lighting system. The ability to customize the lighting for individual patients in rooms with multiple patients was highly appreciated. The findings highlight the importance of close collaboration with occupants and continuous adjustments for a successful implementation and long-term use of CLS in hospitals.

Summary: This research compares three techniques for grasping virtual objects, which differ in terms of how the firmness of users' grip of the controller affects the behavior of the virtual object. The study finds no significant differences between the techniques in terms of perceived task load and usability. However, it suggests that the variable force grip may be perceived as the most realistic and may have an impact on task completion time.

The participants played a two versus-two game, either physically walking or using VR controller while standing. Walking resulted in higher social presence, lower simulator sickness, a more natural experience, a tendency to forget about using controllers, and a concern for maintaining distance from other players.

Summary: This study investigated how spatialized sound affects perceptual detection thresholds for rotation gains in virtual environments with different visibility levels. The results showed no significant effects of sound spatialization or visibility on detection thresholds, indicating that visual rotation gains may be robust to auditory interference and useful even in environments with limited visibility. Further empirical studies are needed to confirm the dominance of vision over audition in this context.
