However, few studies document the successes and setbacks of AR research in the language education sector. This review delves into educational research that employs AR for language training, examining the existing literature on this topic for development trends, benefits, challenges, and success patterns to derive design principles from them. In doing so, the paper covers 40 studies published between 2016 and 2023. The findings suggest that AR is mainly used for vocabulary acquisition with a clear trend toward applying marker-based technology and mobile devices. The design principles derived indicate that the potential of AR lies primarily in contextual learning, and that the technology alone may not satisfy students’ needs in all aspects of language learning but should be used in combination with traditional teaching methods.","PeriodicalId":502489,"journal":{"name":"Frontiers in Virtual Reality","volume":"163 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139849214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This growing trend highlights the pressing need for groundbreaking interventions that can effectively manage palliative symptoms and improve the quality of end-of-life care. We present a brief, structured, personalized, and innovative psychological intervention named Flourishing-Life-Of-Wish Virtual Reality Therapy (FLOW-VRT)®, which capitalizes on the distinctiveness of virtual reality (VR) as an advanced technology for symptom management. FLOW-VRT is theoretically based on self-determination theory, stress coping theory, flow theory, and attention restoration theory. With a special focus on relaxation, “FLOW-VRT-Relaxation” is designed to enhance end-of-life coping through personalized VR relaxation. As most studies on the use of VR in palliative care have been feasibility or pilot studies with small sample sizes, there is a need for a randomized controlled trial with sufficient statistical power.Methods: The current study used a randomized controlled trial (n = 128) to test the efficacy of FLOW-VRT-Relaxation by comparing it to traditional relaxation practice in palliative care.Results: Our results showed that following a FLOW-VRT-Relaxation session, the symptoms of distress that patients in palliative care have to endure significantly reduced, whether physical or emotional in nature.Discussions: The current findings provide promising results regarding the therapeutic potential of using FLOW-VRT-Relaxation as a cost-effective, scalable, and personalized VR relaxation for patients in palliative care.","PeriodicalId":502489,"journal":{"name":"Frontiers in Virtual Reality","volume":"7 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140479101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glowacki","doi":"10.3389/frvir.2023.1286950","DOIUrl":"https://doi.org/10.3389/frvir.2023.1286950","url":null,"abstract":"Near-death experiences (NDEs) and psychedelic drug experiences (YDEs) enable access to dimensions of non-ordinary sensation, perception, and insight beyond typical day-to-day phenomenology. Both are associated with a dissolution of conventional spatio-temporal conceptual distinctions, and a corresponding sense of connectedness and unity. Moreover, NDEs and YDEs have shown a remarkable ability to reduce the anxiety that people associate with death. In two recent papers, we showed that multi-person virtual reality experiences (VREs) designed within the ‘numadelic’ aesthetic (where bodies are represented as light energy rather than material objects) can elicit psychometric results comparable to YDEs. It nevertheless remains an open question why numadelic aesthetics achieve the observed results, especially given that the vast majority of VREs represent bodies as typically perceived in the ‘real-world’. This article describes the origins of the numadelic aesthetic from subjective accounts of NDE phenomenology, and attempts to unravel mechanistic aspects of the numadelic aesthetic by embedding it within a more general theoretical framework. Specifically, we elaborate a 2-axis schematic grounded in predictive coding models of cognition and matter-energy ideas from physics. One axis tracks ‘structural specificity’, and the other tracks ‘symbolic rigidity’. The majority of VREs, which emphasize photorealistic fidelity to content derived from ‘day-to-day’ phenomenology, are characterized by high structural specificity and high symbolic rigidity. Such approaches collapse imaginative potential into a limited low-entropy space of ‘exogenous’ possibility, unlike the high-entropy brain states associated with YDEs. In contrast, aesthetic domains characterized by low structural specificity and low symbolic rigidity are less concerned with fidelity to phenomenological priors, offering an expansive, ‘uncollapsed’ high-entropy possibility space into which participants can project meaning and corresponding endogenous insights can arise (e.g., as occurs in NDEs and YDEs). Situated within this theoretical framing, the numadelic aesthetic emerges as a practical example of an un-collapsed approach to representation, helping to explain the experimental observations within previous papers. Moreover, the theoretical framing suggests various experimental tests, and lays the groundwork for applying numadelic aesthetics to model NDEs, to help address the anxiety often associated with death.","PeriodicalId":502489,"journal":{"name":"Frontiers in Virtual Reality","volume":"54 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140489970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
