Conventional upper limb physiotherapy can be tedious, expensive and require physical transportation. Virtual Reality (VR) video games can help solve these problems. In fact, recent studies show that health professionals are increasingly interested in using VR games for post-stroke rehabilitation. However, commercial possibilities can be inaccessible, in terms of time, space and cost, and also inadequate to the needs of patients and therapists. Thus, in this work, a VR video game with an innovative alternative for tracking the 3D movement of the upper limb is proposed. As a result, a system that uses optical capture with a regular camera and colored sphere markers, while maintaining lightweight real-time processing on mobile devices was done. The fact that the controller can be handcrafted by the users makes the game very low-cost, possible to be distributed worldwide, reaching a large number of people, and possible to be played and monitored remotely. This new form of motion capture can make the VR exergame interaction more intuitive, therefore increasing the user's immersion in his therapy exercises. The proposed system was tested in order to find out how accurate it can be, compared to a gold standard system (a goniometer). It has been found that the system has limitations, such as low accuracy in obtuse angles and camera distortions. Still, it seems promising, due to its accessibility, very low cost, customization to the needs of patients and therapists and good tests results, as a complementary alternative for VR post-stroke rehabilitation.","PeriodicalId":193769,"journal":{"name":"Symposium on Virtual and Augmented Reality","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116847545","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, a robust binocular visual field assessment method based on novel Augmented Reality (AR) glasses is presented, namely, BinoVFAR that can simultaneously find the VF of both eyes. In this method, 60 stimuli in an arrangement of 6 rows and 10 columns randomly appear on a white background on the display of the AR glasses. These stimuli are displayed for 2 seconds that continuously change the intensities from light gray to black. Wearing the AR glasses and focusing on the central fixation point, the users are asked to click the clicker by seen a stimulus. The visible stimuli’s intensities and positions are recorded in a 6 × 10 matrix based on the users’ responses. A bi-cubic interpolation is applied to compute the binocular visual field map (as a 600 × 1000 matrix). A set of experiments (with an average accuracy of 99.93%), including repeatability and reproducibility tests (with an average Intra-class correlation coefficient (ICC) of 99.72%), are conducted to evaluate the BinoVFAR method.","PeriodicalId":193769,"journal":{"name":"Symposium on Virtual and Augmented Reality","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127956630","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}

Nevertheless, manual assembly is susceptible to human errors. Augmented Reality (AR) is one of the enabling technologies to industry 4.0, which has the potential to help by providing on-demand guidance and support monitoring features that comply with Total Quality Management (TQM). Based on these assumptions, the Augmented Reality for Manual Assembly system (RAMM) was developed as an AR system to help PCB‘s manual assembly. A questionnaire was submitted to 124 evaluators. The answers raised questions about the system interface, the devices’ usability and the possible long-term implications of using RAMM. They also found that the software would benefit the assembly of Printed Circuit Boards (PCBs) in many aspects, such as reducing errors, improving quality, novices training, and the way that information resources are presented to the assembler. The functionalities of the system were positively evaluated, which resulted in an overall score of 8.14 (on a scale from 0 to 10). The conclusion is that the RAMM system was able to satisfactorily integrate AR functionalities identified for PCBs assembly, following the principles of TQM and thereby helping to improve the process of manual assembly of PCBs.","PeriodicalId":193769,"journal":{"name":"Symposium on Virtual and Augmented Reality","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128399759","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}

Sharing equipment is no longer a simple strategy; the acquisition of extra equipment is beyond the means of many researchers. Research with Kinect V2 applied to body tracking suffers from sanitary restrictions, product discontinuation and limited access to newer sensors (like the Azure Kinect). Kinect V2 is an RGB-D sensor with many applications in health, ergonomics, sports, games and other areas. That is why a lot of research is still under development with it. Because of the applicability of Kinect V2 on research and the current acquisition limitations, Virtual Kinect (VK) was created. VK is an open-source solution that enables the programmer to code using Kinect SDK functions and test it without a Kinect V2 sensor or a previous recording. It simulates the behavior of a Kinect V2 sensor through MediaPipe’s Pose estimation, providing RGB image and joint tracking information, correlating the joints of the two devices. This correlation is possible due to the proximity of the devices’ joint estimates. The VK was made to be simple and practical, so that its use only depends on the DLL exchange and the use of an ordinary RGB camera.","PeriodicalId":193769,"journal":{"name":"Symposium on Virtual and Augmented Reality","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124547665","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}

However, estimating the face position with an RGB camera is becoming more accessible. In this work, we explore community available face characteristics detection software to implement the FTVR technique for everyday uses of 3D-enabled applications on consumer notebooks without requiring extra devices. We introduce the Parallax Engine solution that can be added with ease to any Unity game engine application. The solution supports two parallax-related visualization options: 1) a monoscopic FTVR mode (FishTank), which locks the virtual camera of the 3D environment to the laptop’s screen 2) and a 2D parallax mode (Parallax2DoF), which allows horizontal and vertical displacement of 3D scene camera. Regarding face characteristics detection techniques, the Parallax Engine uses a standardized interface that can receive input from different methods and currently supports three options: Google’s MediaPipe, dlib, and PoseNet. We evaluated the proposed solution with five users, performing tasks using different options for viewing and face characteristics detection, aiming to understand how suitable it is for end-users. Besides some detection failures from dlib, results showed an overall good acceptance for both the FishTank and Parallax2DoF visualization options.","PeriodicalId":193769,"journal":{"name":"Symposium on Virtual and Augmented Reality","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128173518","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}
