{"title":"VR-based product development process: opportunities and challenges in the automotive industry","authors":"Ingrid Winkler, T. Murari, C. Ferreira, Fábio Freitas","doi":"10.5753/svr_estendido.2022.226711","DOIUrl":"https://doi.org/10.5753/svr_estendido.2022.226711","url":null,"abstract":"In the product development, the success of a manufacturing strategy is achieved by specifying a manufacturing process that it can be produced with minimal impact. In the automotive industry, to detect late, i.e., already during manufacturing phase, issues on customers preferences on new vehicles, physical ergonomic issues, or problems on usability of a product has a high cost of correction and long the time to launch a new product. Thus, given the complexity of products that are under development, designers must perform a number of procedures to guarantee that the finished product fits customer demands and is accepted by the market. With the emergence of low-cost virtual reality devices, the automotive industry is adopting virtual reality for several engineering processes and support everyday engineering. The patent filings have boomed since 2016, in a technology space that is rapidly evolving, offering opportunities to enter an area while it is still young. Virtual reality benefits the product development process by saving costs and time, closing customers, improving interactions, avoiding prototype transportation, optimizing the assembly line, improving the performance and well-being of the user, mitigating hidden dangers, stimulating novel insights and increasing team collaboration, and feeling of engagement, among others. However, certain constraints must be overcome before the technology’s possibilities can be fully harnessed. The challenges faced by VR-based processes are the lack of realism due to unnatural tactile and visual interactions, latency and registration issues, communication difficulties between teams, unpleasant symptoms, issues on depth, haptic, motion and movement perceptions, cybersecurity, cybersickness, lack of intuitiveness, and partial control over the user’s moving around, among others. While there are still challenges to be addressed until industries can fully benefit from the technology’s potential and these constraints prevent virtual reality from fully replacing conventional automotive product development in the near future, it is a valuable contribution to the process. In this context, this work discusses the opportunities and challenges of virtual reality-based product development process in the automotive industry. A better knowledge on this subject may provide a reference for decision-makers, practitioners and researchers as they continue to develop innovative immersive solutions in the product development in the automotive industry.","PeriodicalId":108337,"journal":{"name":"Anais Estendidos do XXIV Simpósio de Realidade Virtual e Aumentada (SVR Estendido 2022)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123587351","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}

Este trabalho apresenta uma pesquisa exploratória para entender as relações entre aprendizagem e recursos de jogos sérios de RV (VRSG), na tentativa de entender as relações entre esses recursos e descobrir maneiras de projetar VRSG eficazes para o aprendizado. ORUN-VR, um jogo sério de RV imersivo, foi projetado, desenvolvido e testado para envolver os alunos e melhorar sua compreensão dos conceitos de cinemática. Experimentos baseados em usuários foram usados para avaliar o engajamento e a presença do jogo, para testar sua usabilidade e aquisição de conhecimento. Além disso, utilizou-se a captura de tela para observar o comportamento do usuário e análise estatística para analisar os resultados. Os resultados de aprendizagem revelaram um ganho de aprendizagem de 52% para os alunos que usaram RV versus aqueles que não usaram, com diferenças de gênero. Além disso, é discutido como o engajamento no jogo, a RV de presença e o gênero afetam os resultados da aprendizagem.","PeriodicalId":108337,"journal":{"name":"Anais Estendidos do XXIV Simpósio de Realidade Virtual e Aumentada (SVR Estendido 2022)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122923987","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}

In this paper, we propose an SG-based system that uses immersive Virtual Reality (iVR) and EMG signal processing to provide a training environment for amputees who are supposed to use myoelectric prostheses. This type of prosthesis requires a more complex control system. The system described in this paper runs on a Vive Pro System using a Vive Tracker to track the user's arm position and orientation and mirror the movement into a virtual prosthesis. EMG signals control the opening and closing of the virtual prosthesis, and vibrational elements placed on the user's forearm provide sensory feedback. The proposed system acts as a useful therapeutic tool for amputee rehabilitation. Our results show that virtual training can be greatly improved when proper tactile feedback is provided, especially for myoelectric controlled prostheses.","PeriodicalId":108337,"journal":{"name":"Anais Estendidos do XXIV Simpósio de Realidade Virtual e Aumentada (SVR Estendido 2022)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129557635","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}

The original objective was to incorporate a Virtual Reality environment into the museum, so that content from different areas of science is made available to any visitors, including scholars, which are the largest share of visitors. The project includes the installation of several Virtual Reality stations in the museum's physical space and the development of games within the scientific approach.

The setup uses an olfactory display that allows the coffee aroma to be part of the user’s experience. This multisensory experience is innovative and astonishing, and it brings users closer to the traditional coffee production process. This project has been presented at the Major Novaes Museum, in Cruzeiro, SP, and has been demonstrated to be a very interesting experience to the users.

The methods already proposed to measure presence rely on user experiments specifically designed. Regardless of the effectiveness of such studies, carrying out user evaluation is extremely costly since it requires expert planning, adequate volunteer recruitment, compliance with ethical standards, long application periods, and statistical analysis of the results. As an alternative, this work presents a lower cost, faster and highly applicable presence evaluation method, the Presence Factor Scale (PFS), which eliminates the need for user evaluations and can be used as a set of guidelines in the design of new VR experiences.","PeriodicalId":108337,"journal":{"name":"Anais Estendidos do XXIV Simpósio de Realidade Virtual e Aumentada (SVR Estendido 2022)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129191933","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}
