    Exposure to sensory stimuli such as aromatherapy and immersion in Virtual Reality (VR) has shown impacts on task performance and emotional state. In this study, we examined the effects of stimuli types (olfactory, visual, and both) and themes (forest and café) in a VR environment to improve students’ performance and mood. While both the stimuli type and theme had no influence on the performance of the Stroop Test, providing olfactory with visual stimuli did increase the level of awakeness compared to providing visuals only or olfactory only. The choice of theme was an important factor in affecting mood; presenting the forest theme made participants feel better, more awake, and calmer compared to presenting the café theme. No interaction effect of stimuli and the theme was observed in any of the studied measurements. More complex tasks should be further tested to see whether aforementioned stimuli can have effects on students’ performance.

    Understanding Multi-user, Handheld Mixed Reality for Group-based MR Games
    Bautista Isaza, Carlos Augusto; Enriquez, Daniel; Moon, Hayoun; Jeon, Myounghoon; Lee, Sang Won (ACM, 2024-04-23)
    Research has identified applications of handheld-based VR, which utilizes handheld displays or mobile devices, for developing systems that involve users in mixed reality (MR) without the need for head-worn displays (HWDs). Such systems can potentially accommodate large groups of users participating in MR. However, we lack an understanding of how group sizes and interaction methods affect the user experience.} In this paper, we aim to advance our understanding of handheld-based MR in the context of multiplayer, co-located games. We conducted a study (N = 38) to understand how user experiences vary by group size (2, 4, and 8) and interaction method (proximity-based or pointing-based). For our experiment, we implemented a multiuser experience for up to ten users. We found that proximity-based interaction that encouraged dynamic movement positively affected social presence and physical/temporal workload. In bigger group settings, participants felt less challenged and less positive. Individuals had varying preferences for group size and interaction type. The findings of the study will advance our understanding of the design space for handheld-based MR in terms of group sizes and interaction schemes. To make our contributions explicit, we conclude our paper with design implications that can inform user experience design in handheld-based mixed reality contexts.
