Effective communication is essential in high-stress environments but stress often disrupts the flow of information and leads to miscommunication. While scenario-based training exercises are widely used, post-hoc reflection and analysis of verbal interactions remain challenging due to overlapping speech, limited analysis time, and the dynamic nature of these situations. This paper introduces ROGER, a novel visual analytics interface designed to support after-action reviews of communication during high-stress training scenarios. Developed in collaboration with police trainers through an iterative design study, ROGER integrates emotional voice metrics, heart rate variability, and spoken language content to provide a comprehensive analysis of team communication. The system enables a flexible in-depth exploration of communication patterns through motifs—repeated sequences or content elements—including those generated by a large language model (LLM) as well as predefined ones. Our approach addresses the limitations of existing tools, which focus primarily on content summarization or voice replays without incorporating emotional and stress-related voice data. We validated the utility through interviews with police trainers and conducted a workshop with medical first responders to investigate the potential for cross-domain applicability. Our findings provide preliminary evidence that ROGER supports effective team performance analysis in diverse high-stress environments. See also supplemental material at https://osf.io/pc6un

In mobile technologies for health and well-being (mHealth), push notifications are a widely used tool to implement persuasive strategies. However, little research has been carried out to investigate the impact of notifications in such technologies and users' attitudes towards them. In this study, we address this gap by exploring the role of notifications and their customisation in the context of mobile applications that promote social, mental, or physical well-being. Based on observational data collected from 152 participants, we investigate users' attitudes and preferences towards notifications and explore how they differ along demographic dimensions. In addition, we then verified these results with behavioural measures and attitude ratings through a user study (N = 31), which saw participants interacting with a prototype of a mHealth application. Our findings show that customisation of notifications is a desired feature that can be used to improve the persuasive aspect of mHealth applications. Implications derived from our study can provide guidance for researchers and practitioners alike when designing app notifications to create better motivating, meaningful, and persuasive experiences.

In the field of medical first responder training, the choice of training modality is crucial for skill retention and real-world application. This study introduces the Green Manikin, an advanced Mixed Reality (MR) tool, conceptually combining the immersiveness of Virtual Reality (VR) with the tangibility of real-world training, and compares it against traditional real-world simulations and VR training. Our findings indicate that MR and real-world settings excel in Self and Social Presence, and in intention to use, offering heightened psychological presence suitable for complex training scenarios. Effort expectancy was highest in real-world environments, suggesting their ease of use for basic skill acquisition. This nuanced understanding allows for better tailoring of training modalities to specific educational objectives. Our research validates the utility of MR and offers a framework for selecting the most effective training environment for different learning outcomes in medical first responder training.

In medical simulation training two approaches are currently rather disjunct: realistic manikins are used to teach physical skills and procedures and VR systems are used to train situation assessment and decision making. We propose a mixed reality approach, which allows trainees to use real tools and their hands when interacting with a physical manikin overlaid with a responsive virtual avatar. In close exchange with first responder organizations, we developed and evaluated an MR training scenario. In the scenario, users can talk to injured people in a car accident, assess the threat of the environment, and utilize real medical equipment. Participants experienced high levels of physical- and self-presence, increased stress levels, and reported a high technology acceptance. The proposed main requirements of first responders regarding haptic multi-sensory skill training in MR and the lessons learned from the workshop aim to guide the design of training solutions for medical training in MR.

Tangible devices and interaction in Extended Reality (XR) increase immersion and enable users to perform tasks more intuitively, accurately and joyfully across the reality-virtuality continuum. Upon reviewing the literature, we noticed no clear trend for a publication venue, as well as no standard in evaluating the effects of tangible XR. To position the topic of tangible XR in the TEI community, we propose a hands-on studio, where participants will bring in their own ideas for tangible XR from their application fields, and develop prototypes with the cutting-edge technology and a selection of virtual assets provided. Additionally, we will collectively reflect upon evaluation methods on tangible XR, and aim to find a consensus of a core evaluation suite. With this, we aim to foster a practical understanding and spark new developments in tangible XR and its use cases within the TEI community.

Immersive virtual training environments are used in various domains. In this work we focus on role-play training in virtual reality. In virtual role-play training conversations and interactions with virtual agents are often fundamental to the training. Therefore, the appearance and behavior of the agents plays an important role when designing role-play training. We focus on the gender appearance of agents, as gender is an important aspect for differentiation between characters. We conducted a study with 40 participants in which we investigated how agents gender appearance influences the perception of the agents´ personality traits and the self-perception of a participants’ assumed role in a training for social skills. This work contributes towards understanding the design-space of virtual agent design, virtual agent gender identity, and the design and development of immersive virtual reality role-play training.
