Live drills are the gold standard for mass casualty incident (MCI) training but are often too resource-intensive for widespread implementation. Immersive technologies offer a promising alternative, but can they deliver comparable fidelity and effectiveness? Working with a local disaster response academy, this paper investigated the potential of Augmented Virtuality (AV) in MCI training through two phases. First, we conducted a landscape analysis of 126 papers across the virtuality continuum, revealing trends in population, training focus, and evaluation metrics. Second, we empirically evaluated an AV system for mass casualty triage training against traditional role-playing and Virtual Reality (VR) approaches, involving 60 trainees in an operational curriculum. Results indicated that both AV and VR surpassed traditional simulations, with AV’s tactile integration significantly enhancing physical engagement, satisfaction, and triage accuracy. Through the lens of triage, we discussed the broader practical implications of integrating immersive technologies like AV into real-world MCI education.

Given the widespread presence of screens during meals, the notion that digital engagement is inherently incompatible with mindfulness. We demonstrate how the strategic design of digital content can enhance two core aspects of mindful eating: slow eating and food awareness. Our research unfolded in three sequential studies: (1). Zoom Eating Study: Contrary to the assumption that video-watching leads to distraction and overeating, this study revealed that subtle video speed manipulations—can promote slower eating (by 15.31%) and controlled food intake (by 9.65%) while maintaining meal satiation and satisfaction. (2). Co-design workshop: Informed the development of ViFeed, a video playback system strategically incorporating subtle speed adjustments and glanceable visual cues. (3). Field Study: A week-long deployment of ViFeed in daily eating demonstrated its efficacy in fostering food awareness, food appreciation, and sustained engagement. By bridging the gap between ideal mindfulness practices and screen-based behaviors, this work offers insights for designing digital-wellbeing interventions that align with, rather than against, existing habits. © 2025 Copyright held by the owner/author(s).
