This paper studies people’s ability to maintain perception of spatial orientation in the real environment while engaged in a virtual experience and explores how visual cues affect the results. Twelve participants performed targeting tasks with rotations, followed by pointing in a known direction to observe the error in perception of real world orientation. Error was measured in three VR environments: visual cues consistent with real world rotation; visual cues slowly changing to become inconsistent with real world; no rotational visual cues. We found that visual cues are essential for people to perceive real-world orientation and removing cues results in drastic disorientation. Moreover, altering visual cues deliberately can be used to control people’s orientation perception to disorientate people in the direction we desire; in our experiment participants did not notice this manipulation. Manipulation of the presentation of visual cues may allow designers to control, correct and manipulate people’s cognitive representation of their orientation and position not only in the virtual world, but also in the real world, be it for in-place redirection or \"redirected standing\", or corrective redirection for safety.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126646446","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}

Until now, researchers have come up with many Virtual Locomotion Techniques (VLT) to supply natural, efficient and usable ways of navigating in VR while not causing VR sickness. Stationary VLTs are those which does not demand any physical movement from the user to travel in the virtual environment. In order to improve the experience of walking in this VLT, it is essential to show the view transition speed that mimics the natural walking speed of the user. In this paper, we describe a within-subject study that was performed to establish a range of perceptually natural walking speeds while being stationary. In the study, we provided vibrotactile feedbacks behind the ears of the subjects to avoid motion sickness. The subjects were exposed to visuals with gains ranging from 1.0 to 3.0. The slowest speed was the estimated natural speed of the user, and the highest speed was three times faster than this. The perceived naturalness of the speed was evaluated using the self-report. We found the range of the visual gain to be 1.40 to 1.78.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115565958","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 task of immersive productive assistance systems is to provide information contextually to the industrial user. Therefore, it is essential to explore the factors and effects that influence the visibility and the corresponding quality of this information. Caused by the technical limitations of additive display technology and application conditions, this new approach has evaluated the immersive visibility of Landolt Rings in various greyscales against ambient illuminance levels on different industrial-like surfaces, coupled with and without a white virtual background. For this purpose, an empirical study in a within-subjects-design with full factorial experimental design (n=23) was conducted on Microsoft HoloLens 2 hardware. The mean values of the main effects indicate that visibility is significantly affected by ambient illuminance (best results at lower level), greyscale (best results at middle level) and virtual background (best results with background). In contrast, the choice of surface is shown to have no statistically significant effect on visibility, however it affects the response time. Additionally, cross-interactions of variables were analyzed and lead to a design recommendation for immersive industrial applications.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"668 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121993036","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 tracking component of virtual reality systems captures data on nonverbal behavior both covertly and continuously at high spatial and temporal fidelity, enabling what is called behavioral tracing. With previous research analyzing this type of data, however, inference has primarily been limited to linear relationships of subject-level aggregates. In this work, we suggest these rough aggregations are often neither the best according to theory nor do they make use of the rich data available from behaviorally traced experiments. We also explore the relationships between motion and subjective experiences with a previously published dataset of 360-degree video and emotion, and we find evidence for nonlinear sample-level relationships. In particular, reported valence relates with head pitch and pitch velocity, among others, and reported arousal relates with head rotation speed and yaw velocity, among others. The role of these sample-level nonlinear relationships for future work are discussed.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123912193","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}

Using oppositional force feedback, provided by a servo, and an augmented visual interface, provided by the user’s smartphone, this tool simulates the look and feel of a physical object within an augmented environment. Additionally, the tool is also able to manipulate physical objects that are not part of the augmented reality, such as a physical nut. By integrating both modes of interaction into the same tool, users can fluidly move between these different modes of interaction, manipulating both physical and virtual objects as the need arises. By overlaying this kind of visual and haptic augmentation onto a common tool such as a pair of pliers, we hope to further explore scenarios for collaborative telepresence in future work.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116207668","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 goal is to address the lack of immersion and intuitive input of conventional systems by providing spatial navigation to extract arbitrary slices from volumetric data directly in three-dimensional space. A 3D model of the medical data is displayed in the real environment, fixed to a particular location, using AR. The tablet is spatially moved through this virtual 3D model and shows the resulting slices as 2D images. We present several techniques that facilitate this overall concept, e.g., to place and explore the model, as well as to capture, annotate, and compare slices of the data. Furthermore, we implemented a proof-of-concept prototype that demonstrates the feasibility of our concepts. With our work we want to improve the current way of working with volumetric data slices in the medical domain and beyond.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"18 25","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134447043","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 includes scenarios where the hands of the user are not available to interact with a system running on such hardware, which precludes some interaction designs from these devices, such as free-hand gestures or the use of a touchpad attached to the device (e.g., on the frame). Alternative modalities include head gestures and speech-based input. However, while these interfaces leave the hands of their users free, they are not as intuitive: common metaphors like touching, pointing, or clicking do not apply. Hence there is an increased need to explain these mechanisms to the user and to make sure they can be used to operate such a device. However, there is no work available on how this should be done properly.In the research presented here, we conducted a study on different ways to support the use of head gestures and voice control on HMDs. For each modality, an abstract as well as an explicit UI design for communicating their usage to users were designed and evaluated in a care setting, where hands-free interaction is necessary to interact with patients and for hygienic reasons. First results from a within-subjects analysis show that surprisingly there does not seem to be much of a difference in performance when comparing these approaches to each other as well as when comparing them to a baseline implementation which offered no additional help. User preferences between the designs diverged: participants often had one clear favourite for the head-gesture UIs while barely noticing the difference between the speech-based UIs. Preferences on certain designs did not seem to impact performance in objective and subjective measures such as error rates and questionnaire results. This suggests that either implementations’ support for these modalities should adapt to individual preferences or that there is a need to focus on other areas of support to increase usability.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134589971","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 main goal of this project is to answer the question about the boundaries of the analogy between interactions with real people and interactions with virtual characters. To investigate this, I plan three lines of research covering performance-based as well as economic and moral decision-making tasks. The tasks will differ in terms of the explicitness of the correct answer (from an easy to define the appropriate solution in performance tasks to the inability to choose the only correct option in moral dilemmas) and complexity of the social situation. The main outcome of the experiments will be the answer to the question of how \"humanly\" are virtual characters treated. I expect that if virtual human are treated like real people, I will observe similar behavioral patterns as when people have real social interactions. Additionally, I plan to systematically manipulate the external characteristics of a virtual character to find the determinants of its influence on participant’s behavior. Specifically, I will attempt to achieve the level of realism appropriate to induce a sense of copresence and consequent influence of virtual characters on people’s behavior. The entire project will therefore answer a broader question about the possibility, scope and nature of the influence of virtual characters on human behavior.","PeriodicalId":244088,"journal":{"name":"2021 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114670620","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}
