This study aimed: (1) to investigate the association between the presence in the virtual environment, the usability of the system, the intrinsic motivation, and immersion in VR gaming designed for rehabilitation after musculoskeletal injury; and (2) to examine the users' emotional response in terms of pleasure, arousal, and dominance, after participating in VR gaming. Thirty-seven individuals aged 23.69 ± 6.98 years participated in five customized VR games designed to provide a complete rehabilitation session after a musculoskeletal injury. Pearson product-moment correlation coefficients and multiple regression analyses were used to investigate the relationship between presence in virtual environments and immersive tendencies, the usability of the system, and intrinsic motivation. The Wilcoxon Signed Rank Test was conducted to evaluate the impact of participation in VR gaming on participants' presence in virtual environments. Significant correlations were found between presence and immersive tendencies (r = −.40, p = .017), intrinsic motivation (r = .42, p = .013), and usability of the system (r = .64, p &lt; .001). The linear regression model explained 59% of the total variance in the presence of virtual environments. There was a statistically significant increase in the pleasure scores from the beginning to the end of the session. Our results indicate that VR may be useful in increasing adherence to treatment to recover musculoskeletal injuries.","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135303882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typical two-box models assume instant and fully mixed air volumes, which can potentially cause issues in cases with fast processes, slow air mixing, and/or large volumes. In this study, we present an aerosol dispersion model and validate it by comparing the modelled concentrations with concentrations measured during chamber experiments. We investigated whether a better estimation of concentrations was possible by using different geometrical layouts rather than a typical two-box layout. A one-box, two-box, and two three-box layouts were used. The one box model was found to underestimate the concentrations close to the source, while overestimating the concentrations in the far field. The two-box model layout performed well based on comparisons from the chamber study in systems with a steady source concentration for both slow and fast mixing. The three-box layout was found to better estimate the concentrations and the timing of the peaks for fluctuating concentrations than the one-box or two-box layouts under relatively slow mixing conditions. This finding suggests that industry-relevant scaled volumes should be tested in practice to gain more knowledge about when to use the two-box or the three-box layout schemes for multi-box models.","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2018-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75192861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inherent strong dispersion limits their use in full spectrum imaging, causing unacceptable loss of color fidelity. In particular, metamerism introduces a data dependency in the image blur, which has been neglected in computational imaging methods. We introduce both a diffractive achromat based on computational optimization, as well as a corresponding cross-scale algorithm for correction of residual aberrations. The height profile of a diffractive lens is optimized to balance the focusing contributions of different wavelengths. The nearly identical spectral point spread functions (PSFs) create approximately spectrally invariant blur kernels. This property guarantees good color preservation and facilitates correction of residual aberrations in our fast two-step deconvolution without additional color priors. We demonstrate a diffractive achromat on a 0.5mm ultrathin substrate, with producing high color fidelity and better image quality in full visible spectrum.","PeriodicalId":54588,"journal":{"name":"Presence-Teleoperators and Virtual Environments","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78798277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
