This literature review examines the existing research into cybersickness reduction with regards to head mounted display use. Cybersickness refers to a collection of negative symptoms sometimes experienced as the result of being immersed in a virtual environment, such as nausea, dizziness, or eye strain. These symptoms can prevent individuals from utilizing virtual reality (VR) technologies, so discovering new methods of reducing them is critical. Our objective in this literature review is to provide a better picture of what cybersickness reduction techniques exist, the quantity of research demonstrating their effectiveness, and the virtual scenes testing has taken place in. This will help to direct researches towards promising avenues, and illuminate gaps in the literature. Following the preferred reporting items for systematic reviews and meta-analyses statement, we obtained a batch of 1,055 papers through the use of software aids. We selected 88 papers that examine potential cybersickness reduction approaches. Our acceptance criteria required that papers examined malleable conditions that could be conceivably modified for everyday use, examined techniques in conjunction with head mounted displays, and compared cybersickness levels between two or more user conditions. These papers were sorted into categories based on their general approach to combating cybersickness, and labeled based on the presence of statistically significant results, the use of virtual vehicles, the level of visual realism, and the virtual scene contents used in evaluation of their effectiveness. In doing this we have created a snapshot of the literature to date so that researchers may better understand what approaches are being researched, and the types of virtual experiences used in their evaluation.

A Scoping Review of Assistance and Therapy with Head-Mounted Displays for People Who Are Visually Impaired
Given the inherent visual affordances of Head-Mounted Displays (HMDs) used for Virtual and Augmented Reality (VR/AR), they have been actively used over many years as assistive and therapeutic devices for the people who are visually impaired. In this paper, we report on a scoping review of literature describing the use of HMDs in these areas. Our high-level objectives included detailed reviews and quantitative analyses of the literature, and the development of insights related to emerging trends and future research directions. Our review began with a pool of 1251 papers collected through a variety of mechanisms. Through a structured screening process, we identified 61 English research papers employing HMDs to enhance the visual sense of people with visual impairments for more detailed analyses. Our analyses reveal that there is an increasing amount of HMD-based research on visual assistance and therapy, and there are trends in the approaches associated with the research objectives. For example, AR is most often used for visual assistive purposes, whereas VR is used for therapeutic purposes. We report on eight existing survey papers, and present detailed analyses of the 61 research papers, looking at the mitigation objectives of the researchers (assistive versus therapeutic), the approaches used, the types of HMDs, the targeted visual conditions, and the inclusion of user studies. In addition to our detailed reviews and analyses of the various characteristics, we present observations related to apparent emerging trends and future research directions.

Daniel Ballin, Robert D (Ed.)The use of multimodal data allows excellent opportunities for human–computer interaction research and novel techniques regarding virtual and augmented reality (VR/AR) experiences. Collecting, coordinating, and synchronizing a large amount of data from multiple VR/AR hardware while maintaining a high framerate can be a daunting task, despite the compelling nature of multimodal data. The Lab Streaming Layer (LSL) is an open-source framework that enables the synchronous collection of various types of multimodal data, unlike existing expensive alternatives. However, despite its potential, this framework has not been fully adopted by the VR/AR research community. In this paper, we present a guideline of the LSL framework’s use in VR/AR research as well as report current trends by performing a comprehensive literature review on the subject. We extract 549 publications using LSL from January 2015 to March 2022. We analyze types of data, displays, and targeted application areas. We describe in-depth reviews of 38 selected papers and provide use of LSL in the VR/AR research community while highlighting benefits, challenges, and future opportunities.more » « less

null (Ed.)There is a cohesive body of research on the effectiveness of problem-based learning (PBL) for a wide range of learner groups across different disciplines in engineering education. On the other hand, there is a growing interest in using immersive technologies such as virtual reality (VR) in engineering education. While there are many literature review articles on each of these subjects separately, there is a lack of review articles on the application of combined PBL-VR learning environments in engineering education. This paper provides an assessment of the applications and potential of implementing immersive technologies in a PBL setting to utilize the advantages of both paradigms. More specifically, this paper aims to provide insights related to two main questions: (1) where (in what disciplines/subjects) PBL and VR have been used together in engineering education? And, (2) how are VR and PBL integrated and used in engineering education? The first question is investigated by performing a bibliometric analysis of relevant papers published in the proceedings of previous ASEE annual conferences. The second question is explored by performing a literature review and classification of ASEE papers that discuss the use of VR in conjunction with PBL. Our findings reveal a gap between the application of integrated PBL and VR across different disciplines in engineering education. We also analyze the trends related to PBL and VR application in engineering education over time. Finally, we identify and propose future opportunities related to the combination of PBL and immersive technologies, including but not limited to immersive simulation-based learning (ISBL) and incorporating artificial intelligence (AI) into immersive virtual/simulated learning environments used in engineering education.more » « less

Activity-dependent neuronal plasticity is crucial for animals to adapt to dynamic sensory environments. Traditionally, it has been investigated using deprivation approaches in animal models primarily in sensory cortices. Nevertheless, emerging evidence emphasizes its significance in sensory organs and in sub-cortical regions where cranial nerves relay information to the brain. Additionally, critical questions started to arise. Do different sensory modalities share common cellular mechanisms for deprivation-induced plasticity at these central entry-points? Does the deprivation duration correlate with specific plasticity mechanisms?
This study systematically reviews and meta-analyses research papers that investigated visual, auditory, or olfactory deprivation in rodents of both sexes. It examines the consequences of sensory deprivation in homologous regions at the first central synapse following cranial nerve transmission (vision-lateral geniculate nucleus and superior colliculus; audition-ventral and dorsal cochlear nucleus; olfaction-olfactory bulb). The systematic search yielded 91 papers (39 vision, 22 audition, 30 olfaction), revealing substantial heterogeneity in publication trends, experimental methods, measures of plasticity, and reporting across the sensory modalities. Despite these differences, commonalities emerged when correlating plasticity mechanisms with the duration of sensory deprivation. Short-term deprivation (up to 1 day) reduced activity and increased disinhibition, medium-term deprivation (1 day to a week) involved glial changes and synaptic remodelling, and long-term deprivation (over a week) primarily led to structural alterations.
These findings underscore the importance of standardizing methodologies and reporting practices. Additionally, they highlight the value of cross-modals synthesis for understanding how the nervous system, including peripheral, pre-cortical, and cortical areas, respond to and compensate for sensory inputs loss.
Significance Statement This study addresses the critical issue of sensory loss and its impact on the brain's adaptability, shedding light on how different sensory systems respond to loss of inputs from the environment. While past research has primarily explored early-life sensory deprivation, this study focuses on the effects of sensory loss in post-weaning rodents. By systematically reviewing 91 research articles, the findings reveal distinct responses based on the duration of sensory deprivation. This research not only enhances our understanding of brain plasticity but also has broad implications for translational applications, particularly in cross-modal plasticity, offering valuable insights into neuroscientific research and potential clinical interventions. -
There are a variety of urgent calls for institutional initiatives and actions to transform engineering education. For a transformational change to occur, the initiatives must alter the culture of the institutions (Eckel, Hill, and Green, 1998). In this work in progress, we detail the methods used to conduct a scoping literature review (ScR) concerning the current state of the literature surrounding institutional culture and transformational change in engineering education at institutions of higher learning in the United States. As institutional culture and transformational change are currently underexplored topics in the engineering education literature, we investigated the larger body of computer science and engineering literature in the United States. Once completed, this study aims to reveal the current trends, theories, and potential gaps in the literature regarding these topics. Arksey and O’Malley’s methodology for conducting scoping reviews informed the development of our scoping review protocol, which similarly includes five stages: (1) identify the research questions, (2) identify relevant studies, (3) select relevant studies, (4) chart the data, and (5) collate, summarize, and report results (Arksey and O’Malley, 2005). University librarians who specialize in conducting systematic reviews aided in the refinement of this protocol. From the research question and aim of the study, three main inclusion criteria were created: (1) the literature must discuss both organizational culture and transformational change, (2) discussion of transformational change must describe the institution where the change happened, and (3) the literature must emphasize the agents of transformational change. Additional inclusion and exclusion criteria were created in collaboration with both the librarians and reviewers. These criteria guided the search for existing literature in the following online databases: Elsevier (Engineering Village – Compendex and Engineering Village – INSPEC), ProQuest (ERIC and Education Database), Scopus, and Web of Science. These six databases were selected as they often include publications relevant to the field of engineering education. After the search was conducted, the inclusion and exclusion criteria were turned into questions to inform a three-step screening process (title, abstract, and full text) used by reviewers to determine whether a publication was eligible for the study. Reviewers were assigned to review papers through Covidence, a cloud-based systematic literature review management platform. There are currently two primary reviewers and a third additional reviewer to resolve any conflicts or disagreements if they should arise. Before each review cycle, the inclusion and exclusion criteria are revisited, revised, and agreed upon by the three reviewers. This screening process is performed iteratively, allowing for critical reflection at each stage to drive the resulting findings by the reviewers in consultation with content matter experts. We are currently conducting our first round of screening in the study selection (third stage) of the scoping review protocol. After the removal of duplicates, 999 publications were found by searching in the six selected databases. This number is expected to be further reduced with each step of the screening process. When this scoping review is complete, the resulting publication will contain an analysis of the literature and synthesis of our findings, and present the prominent themes, theories, and potential gaps in the literature. This publication is expected to unite disparate lines of research on institutional culture and transformational change, challenge the assumptions in the field, and change the way engineering education views transformational change.more » « less
