In policing, Virtual Reality scenario-based training (VR SBT) is being explored to complement real-life scenario-based training (RL SBT). We investigated whether relevant training responses in VR SBT, namely heart rate (HR), level of physical activity, mental effort, and perceived stress, resemble those in RL SBT. Utilizing a within-subject study design, we investigated the training responses of 237 police officers of the Dutch National Police. We found that the maximum HR and average level of physical activity were significantly higher in RL SBT, whereas invested mental effort was significantly higher in VR SBT. No significant differences were found in average HR and perceived stress. We also found that perceived stress in VR was predicted by participants’ VR experiences such as engagement with VR and experience of negative effects, but not by participant characteristics. Participants’ mental effort in VR was predicted by their VR experiences and participant characteristics, particularly gaming frequency. In conclusion, VR SBT can elicit perceived stress, mental effort, and average HR that resemble or exceed responses in RL SBT, providing a promising tool to complement police training.

Virtual training systems provide highly realistic training environments for police. This study assesses whether a pain stimulus can enhance the training responses and sense of the presence of these systems. Police officers (n = 219) were trained either with or without a pain stimulus in a 2D simulator (VirTra V-300) and a 3D virtual reality (VR) system. Two (training simulator) × 2 (pain stimulus) ANOVAs revealed a significant interaction effect for perceived stress (p =.010, ηp2 =.039). Post-hoc pairwise comparisons showed that VR provokes significantly higher levels of perceived stress compared to VirTra when no pain stimulus is used (p =.009). With a pain stimulus, VirTra training provokes significantly higher levels of perceived stress compared to VirTra training without a pain stimulus (p <.001). Sense of presence was unaffected by the pain stimulus in both training systems. Our results indicate that VR training appears sufficiently realistic without adding a pain stimulus. Practitioner summary: Virtual police training benefits from highly realistic training environments. This study found that adding a pain stimulus heightened perceived stress in a 2D simulator, whereas it influenced neither training responses nor sense of presence in a VR system. VR training appears sufficiently realistic without adding a pain stimulus.

Abstract Background People with epilepsy and mild intellectual disability have a limited adaptive capacity resulting in difficulties in communication and social skills. Virtual Reality (VR) has the potential to help this group of people to learn how to manage difficult situations. SEIN (Expertise Center for Epilepsy) provides training to the residents to improve their social and communication skills. The purpose of the exploratory study was to establish whether VR could be a suitable digital means to provide a more efficient blended training. Methods Online interviews were conducted with healthcare professionals from SEIN: two coordinators, three psychologists and two coaches. The participants were asked about their ideas for improving the social skills of the residents and their view on using VR to do so. Interviews were recorded, transcribed and analyzed using thematic analysis approach. In addition, observations were conducted during a training session to get a realistic sense of its process and contents. Observations were noted in a logbook. Findings The participants are positive to use VR in the training but point out that it is not suitable for all the residents. VR glasses were ruled out because it put the resident alone in a virtual setting. VR with a tablet is preferred to allow the residents and the healthcare professional to simultaneously view 3D simulated situations and allowing opportunities to talk about it. The development of VR contents and simulations using tablet will need to take into account relevant VR guidelines dedicated to people with epilepsy. Appropriate training for the healthcare professionals also needs to be provided. Conclusions The use of Virtual Reality in training programs to improve communication and social skills of adults with intellectual disabilities and epilepsy is promising, We advocate to utilize user-centered design and co-creation approaches with all concerned parties for further development of tablet-based VR solutions

Abstract Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently flled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fts-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efcacy of AR and VR training tools.

The After-Action Review (AAR) in Virtual Reality (VR) training for police provides new opportunities to enhance learning. We investigated whether perspectives (bird’s eye & police officer, bird’s eye & suspect, bird’s eye) and line of fire displayed in the AAR impacted the officers’ learning efficacy. A 3 x 2 ANOVA revealed a significant main effect of AAR perspectives. Post hoc pairwise comparisons showed that using a bird’s eye view in combination with the suspect perspective elicits significantly greater learning efficacy compared to using a bird’s eye view alone. Using the line of fire feature did not influence learning efficacy. Our findings show that the use of the suspect perspective during the AAR in VR training can support the learning efficacy of police officers.Practitioner summary: VR systems possess After-Action Review tools that provide objective performance feedback. This study found that reviewing a VR police training scenario from the bird’s eye view in combination with the suspect perspective enhanced police officers’ learning efficacy. Designing and applying the After-Action Review effectively can improve learning efficacy in VR.

This paper reports on the EU-project 'Professionally Networking Education and Teacher Training' (PRONETT). The key objective of the PRONETT project (2001-2004) is to develop a regional and cross national learning community of pre- and in-service teachers and teacher educators supported by webbased resources and tools to collaborate and to construct shared understandings of teaching and learning in a networked classroom. The reasons for the initiative and the design principles of the PRONETT portal offering a virtual infrastructure for the collaboration of participating students and teachers at www.PRONETT.org are presented. The initial pilots carried out by the project partners are described, highlighting the co-ordinating partners activities targeted at contributing to the local realisation of ICT-rich, competence based Teacher Education Provision. Results are reported of the evaluation and implementation efforts aimed at validating the original portal design and collecting information to inspire further project development and implementation strategies. We conclude by summarising the lessons learned and providing recommendations for improved and extended use and further dissemination of the project results and facilities.

Seven college lecturers and two senior support staff were interviewed during 2021 about their experiences teaching in hybrid virtual classrooms (HVC). These technology-rich learning environments allow teachers to simultaneously teach students who are in class (on campus) and students who are joining remotely (online). There were two reasons for this choice: first, ongoing experimentation from innovative teaching staff who were already using this format before the COVID-19 pandemic; secondly, as a possible solution to restrictions on classroom size imposed by the pandemic. Challenges lecturers faced include adjusting teaching practice and lesson delivery to serve students in the class and those online equally; engaging and linking the different student groups in structured and natural interactions; overcoming technical challenges regarding audio and visual equipment; suitably configuring teaching spaces and having sufficient pedagogical and technical support to manage this complex process. A set of practical suggestions is provided. Lecturers should make reasoned choices when teaching in this format since it requires continued experimentation and practice to enhance the teaching and learning opportunities. When external factors such as classroom size restrictions are the driving force, the specific type of synchronous learning activities should be carefully considered. The structure and approach to lessons needs to be rethought to optimise the affordances of the hybrid virtual and connected classroom. The complexity of using these formats, and the additional time needed to do it properly, should not be underestimated. These findings are consistent with previous literature on this subject. An ongoing dialogue with faculty, support staff and especially students should be an integral part of any further implementation in this format.

Designers are increasingly collaborating with various stakeholders to address complex societal challenges. These challenges often require a codesign approach, where differ-ent actors with diverse perspectives and experiences unite to explore innovative ave-nues for change. Such collaboration requires empathy between the actors to under-stand each other’s perspective better in their interactions. This paper aims to assist so-cial designers in orchestrating such empathic codesign processes by introducing an Em-pathic Journey framework. This conceptual and practical framework is based on em-pathic design theory and three design cases which used Virtual Reality for perspective exchange between actors. The framework addresses the importance of integrating an emotional spark through immersion and the necessity of embedding immersive experiences in a larger journey.

This paper presents the design and the results of a comparative study of multidisciplinary on-scene command teams at work in virtual emergency training exercises. The principal goals of the study were to understand how "on-scene command teams" coordinate on multidisciplinary objectives and tasks, and how the manner in which this is done affects their performance. The study involved 20 on-scene command teams consisting of various individuals, such as police, fire and medical services personnel, municipal officers and infrastructure operators, drawn from a Safety Region in The Netherlands. Integrated video recordings by five synchronized cameras captured the coordination processes during the virtual exercises. The integrated and synchronized video recordings were then transformed into numerical data for analysis. Performance was operationalized by scoring the progress and completion of emergency management tasks for which individual members and/or teams as a whole were responsible. Team coordination was operationalized using network centrality and density measures. The significant findings are the following: (i) emergency management performance and coordination patterns within and among on-scene command teams have considerable variation; and (ii) teams that use less coordination during the intermediate phases of emergency management perform significantly better than teams that do not, moreover, actors who have central positions in a network are better able to achieve their performance goals.
