In order to improve the user experience of digital museum, the evaluation and optimization methods of visitors' emotional experience of digital museum based on virtual reality technology and emotion recognition algorithm are studied. The spectrogram is generated according to the voice sent by tourists when they visit the digital museum, which is based on CSWNet_ CRNN emotion recognition depth learning model input, evaluate the tourists' emotional experience results, and draw the tourists' emotional types of digital museums; The visual and auditory features of the digital museum scene with positive emotional experience are extracted respectively. Using virtual reality technology, the extracted features are applied to each link of the digital museum scene content design, optimizing the digital museum virtual reality scene, and improving the digital museum experience. The experiment shows that the tourist emotion recognition accuracy of this method is high, and the emotion recognition accuracy of 300 random tourists can reach 100%. In terms of generating new scenes, the feature extraction results of this scene are consistent with the feature estimation of positive emotions by ordinary people. The use of extracted features to optimize the digital museum scene has better realism and detail accuracy, which can be favored by most people and promote the sustainable development of digital museums.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"115 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140985758","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 development of virtual reality offers an opportunity to assess this dimension from an interactionist perspective and to increase the ecological validity of the material used. However, this approach can be operationalized and conceptualized in a variety of ways. To understand these aspects, we conducted a systematic review of articles found in the PubMed, PubMed Central and ScienceDirect databases, following PRISMA-P guidelines. A corpus of 48 articles was identified and analyzed in terms of the experimental devices used, to gauge the extent to which they reproduced the characteristics of real-world social interactions, as well as the associated conceptions. Results suggested that interactionist research lies on a continuum between ecological validity (studies exploring interactions via general functions) and a high level of experimental control (exploration of interactions with respect to specific processes). They are discussed in terms of the operationalization and objectification of interactionism.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"98 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017655","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}

Therefore, it is necessary to find solutions to this limitation. A possible solution could be to reuse this workspace by overlapping different parts of the virtual space. This can be achieved through the use of imperceptible portals that connect different points in the virtual environment. Thanks to these portals it is possible to create a momentary break in the conventional Euclidean geometry displaying parts of the virtual world that are farther away than usual. Although this kind of effect has been seen in conventional games, its application to virtual environments has some technical implications. One of the most important technical characteristics to be evaluated is the presence, which could be affected by this type of visual effect. For this reason, a validation of the effect has been carried out by quantitatively analyzing the perceptual presence and conducting qualitative interviews with users. The results did not show an overall impact on presence, and users were excited to experience this type of visual effect inside the virtual world. Finally, this article shows everything learned in this development and is discussed from a perceptual design point of view, opening the possibility of new studies associated with this visual effect applied to the virtual world.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"98 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140371163","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}

Therefore, it becomes important to understand the performance of human hand-reaching movement in MR. Studies have shown that different virtual environment visualization modalities can affect point-to-point reaching performance using a stylus, but it is not yet known if these effects translate to direct human-hand interactions in mixed reality. This paper focuses on evaluating human point-to-point motor performance in MR and VR for both finger-pointing and cup-placement tasks. Six performance measures relevant to haptic interface design were measured for both tasks under several different visualization conditions (“MR with indicator”, “MR without indicator”, and “VR”) to determine what factors contribute to hand-reaching performance. A key finding was evidence of a trade-off between reaching motion confidence” measures (indicated by throughput, number of corrective movements, and peak velocity) and “accuracy” measures (indicated by end-point error and initial movement error). Specifically, we observed that participants tended to be more confident in the “MR without Indicator” condition for finger-pointing tasks. These results contribute critical knowledge to inform the design of VR/MR interfaces based on the application's user performance requirements.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"125 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369931","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}

We compared this collaborative version to a non-collaborative version in a between-subjects experimental study (n = 20), finding that student teams using the collaborative version interacted to a larger extent while performing the subgames. The students in these teams self- reported a higher level of engagement, and observations suggested that interactions extended beyond necessary instructions. We did not find any significant differences when it comes to learning measured by scores on pre- and post-knowledge tests, but quantitative analysis of responses indicates that the VR-experience affected students overall and a qualitative analysis of an open question suggested a particular effect on the collaborative teams. Logged performance data indicated that collaborative teams managed to solve the tasks involved in the subgames at least as efficiently as the teams using the non-collaborative version.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"142 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369201","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 phenomenon concerns presence and immersion in the illusion of self-motion, especially in virtual reality. In the present study, we investigated how the real-life meaning of stimuli contributes to vection by using animations of objects that can move by themselves. In two psychophysical experiments, we first employed animated cars presented with or without wheel rotation as the visual inducer, which had various motion directions and postures; then we added the road scenery, which was either moving (in the same or opposite direction to the cars) or still, as a contextual background in the visual stimulus. The results of Experiment 1 showed that in conditions with forward- and backward-moving cars, vection was stronger than in conditions with upward-moving and inverted cars. The results of Experiment 2 showed that vection was weakest in the still road scenery condition and that the cars' wheel rotation could facilitate vection. This suggests that the more natural the stimulus meanings were, the stronger the vection was. It is a feasible and effective application prospect to enhance the vection experience by changing the naturalness of the stimulus to further increase the sense of presence and immersion. Therefore, the perceived naturalness and the assumed staticity of the visual inducer are two important cognitive factors in visual selfmotion perception and presence in the virtual world.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140214701","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}
