With LiDAR equipped with an RGB camera, users can calibrate the projector in just two scans. Because this system knows the ray formula for every pixel shooting from the projector, it can make accurate projections. In particular, the system introduces how to perform linear interpolation in the process of obtaining a formula and a methodology that allows users to immediately know the 3D coordinates of a desired part in a 2D image. Through a long-distance experiment, the projection mapping result of the proposed method showed an error of less than 5mm, and the existing system had a maximum error of 30mm.","PeriodicalId":412598,"journal":{"name":"2023 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126401714","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}

Technologies like Augmented Reality (AR) have been shown to be useful for medical teaching and guidance and may contribute to the training of medical experts in these countries. While still expensive, AR has low infrastructure requirements like cell phones, where ownership has constantly increased over the last few years. However, AR is mainly tested for training and surgical applications in highly developed environments. In this study, we tested whether AR can also address the needs for healthcare and medical education in East Africa. Our study consisted of a medical need-finding part and a pilot study to address some of these needs with AR. Our study shows that remote teaching via AR led to significantly higher test score gains and more consistent results than in the in-person control group.","PeriodicalId":412598,"journal":{"name":"2023 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121104940","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}

For medical image visualization, XR offers promising benefits but also design and evaluation challenges. In this preliminary work, direct observations and interviews were conducted with two expert health workers (one surgeon and one radiologist) who used an XR technology to perform immersive anatomic visualization for surgical planning for two years. Interaction requirements and expectations were collected, which provided a basis for the position that communication during surgical planning improves if the virtual environment offers interaction models for both medical specialties. Subsequently, a technical review of medical image visualization software in PC and XR platforms was carried out to analyze the interaction techniques provided to the users. Finally, interaction models were conceived to offset the lack of interaction techniques oriented to the surgeon's needs.","PeriodicalId":412598,"journal":{"name":"2023 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"7 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120996741","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}

Unlike previous Speech-based gesture generation method, our proposal reflects the user's actual pose using a vision-based system and speech as a subsidiary. When the system detects the camera out of sight, we carry out a context-aware method analyzing the speech. The system determines the target pose and connects it with the last pose captured by the camera using the bounding box. Our system can be a robust solution for avatar-mediated remote collaboration which requires accurate gesture delivery such as VR remote yoga training.","PeriodicalId":412598,"journal":{"name":"2023 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125123175","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 flexible creation of animations is a significant yet challenging task due to the heterogeneous topologies and shapes of avatars. To allevi-ate this, we propose a unified proxy skeleton for retargeting (UPSR) to achieve consistent motions of the virtual avatar. Particularly, the heterogeneous topologies are converted into a unified skeleton topol-ogy of the avatars by using a learned nonlinear mapping function. Furthermore, we propose to retarget the skeletons with different body shapes into 3D virtual avatars. Our UPSR can produce avatar animations with a higher level of authenticity without the depen-dency on high-cost motion capture devices or the restrictions of its topology. Additionally, we could drive detailed motions based on multiple sources of motion datasets, including monocular videos, motion capture devices, and standard motion files, with the precise motion capture of eyes, lips, hands, and bodies.","PeriodicalId":412598,"journal":{"name":"2023 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406102","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}
