Kemo-mimi is often used as an element of the avatar’s appearance. It is generally considered that the posture of animal ears represents the animal’s emotional state. And the idea has been used as a technique for expressing emotions in many cartoon and animation works. But despite this fact, there are few examples of studies on the emotions that can be expressed by animal ears. Therefore, we decided to investigate the relationship between the posture of the animal ears and emotions and to establish a method of expressing emotions using the ears. In the experiments, three-dimensional animations of animal ears changing posture were presented to the subjects, and they were asked to answer the emotion corresponding to the posture. The results showed that there was a certain degree of a common understanding of people’s impressions concerning the animal ears. In this paper, we report the emotions that can be expressed by the posture of the animal ears as revealed in this study.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133700882","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}

Our main approach is to track vertical in-place foot movements of a user using a Kinect v2 sensor and map tracked foot height to the motions of inverse kinematics (IK) targets. We align two IK targets with an avatar's feet and guide the virtual feet to perform cyclic walking motions using a set of kinematic equations. Preliminary testing shows that this approach can produce compelling real-time forward-backward leg animation during in-place walking.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115716702","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}

Existing work has shown the benefits of precueing movement (translation) information. However, rotation is also a major component in many real-life tasks, such as turning knobs to adjust parameters on a console. We developed an AR testbed to investigate whether and how much precued rotation information can improve user performance. We consider two unimanual tasks: one requires a user to make sequential rotations of a single object, and the other requires the user to move their hand between multiple objects to rotate them in sequence. We conducted a user study to explore these two tasks using circular arrows to communicate rotation. In the single-object task, we examined the impact of number of precues and visualization style on user performance. Results show that precues improved performance and that arrows with highlighted heads and tails, with each destination aligned with the next origin, yielded the shortest completion time on average. In the multiple-object task, we explored whether rotation precues can be helpful in conjunction with movement precues. Here, using a rotation cue without rotation precues in conjunction with a movement cue and movement precues performed the best, implying that rotation precues were not helpful when movement was also required.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"76 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130605589","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}

Previous work showed that avatars’ stereotypical appearance can affect users’ physical performance and perceived exertion while exercising in VR. Although sweating is a natural human response to physical effort, surprisingly little is known about the effects of sweating avatars on users. Therefore, we conducted a study with 24 participants to explore the effects of sweating avatars while cycling in VR. We found that visualizing sweat decreases the perceived exertion and increases perceived endurance. Thus, users feel less exerted while embodying sweating avatars. We conclude that sweating avatars contribute to more effective exergames and fitness applications.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131246538","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}

Although the Taiwan government and various Taiwanese opera troupes have worked hard for many years to promote this culture to campuses, and held several interest courses; this culture inheritance is still losing and dying. For elder people, Taiwanese opera and Taiwanese cultures are both precious culture treasures and parts of their childhood memories. Nowadays, young people in Taiwan are no longer familiar to Taiwanese, neither to Taiwanese opera singings. It is hard for young people to learn how appreciating this traditional culture. In this study, we refer to the current promotion methods of drama troupes which learn the singing method and posture of Taiwanese opera, we combine artificial intelligence techniques into traditional Taiwanese opera on singing and posture. The proposed system could analyzes students’ voice and postures, and then assists teachers to improve the learning performance of students. Students could compare their singing skill or postures with professional actors and adjust their singing and posture. Students of Taiwanese opera interest class can practice independently without professional teacher's guidance at home. In campus promotion, this game-like promotion method brings young people more acceptance of Taiwanese opera.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126928146","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}

Buildings in the city square are learning modules which include typical knowledge units, assessment booths, or custom collaborative sketching studios.

For example, an augmented reality (AR) user might use one type of head-mounted display (HMD) in a physical environment, while a virtual reality (VR) user might wear a different type of HMD and see a virtual model of that physical environment. To explore the effects of such asymmetric interfaces on collaboration we present a study that investigates the behaviour of dyads performing a word puzzle task where one uses AR and the other VR. We examined the collaborative process through questionnaires and behavioural measures based on positional and audio data. We identified relationships between presence and co-presence, accord and co-presence, leadership and talkativeness, head rotation velocity and leadership, and head rotation velocity and talkativeness. We did not find that AR or VR biased subjective responses, though there were interesting behavioural differences: AR users spoke more words, AR users had a higher median head rotation velocity, and VR users travelled further.","PeriodicalId":134843,"journal":{"name":"Proceedings of the 28th ACM Symposium on Virtual Reality Software and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115336363","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}
