In contrast to the effects of uniform latency degradation, the influence of latency jitter on user experience in VR is not well researched, although today's consumer VR systems are vulnerable in this respect. In this work we report on the impact of latency jitter on cybersickness in HMD-based VR environments. Test subjects are given a search task in Virtual Reality, provoking both head rotation and translation. One group experienced artificially added latency jitter in the tracking data of their head-mounted display. The introduced jitter pattern was a replication of a real-world latency behavior extracted and analyzed from an existing example VR-system. The effects of the introduced latency jitter were measured based on self-reports simulator sickness questionnaire (SSQ) and by taking physiological measurements. We found a significant increase in self-reported simulator sickness. We therefore argue that measure and control of latency based on average values taken at a few time intervals is not enough to assure a required timeliness behavior but that latency jitter needs to be considered when designing experiences for Virtual Reality.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125172099","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 our work, we enable all these properties thanks to an efficient soft hand simulation model. This model integrates an articulated skeleton, nonlinear soft tissue and frictional contact, to provide the realism necessary for natural interaction. Robust and smooth interaction is made possible by simulating in a single energy minimization framework all the mechanical energy exchanges among elements of the hand: coupling between the hand's skeleton and the user's motion, constraints at skeletal joints, nonlinear soft skin deformation, coupling between the hand's skeleton and the soft skin, frictional contact between the skin and virtual objects, and coupling between a grasped object and other virtual objects. We have put our effort on describing all elements of the hand that provide for realism and natural interaction, while ensuring minimal and bounded computational cost, which is key for smooth and robust interaction. As a result, we accomplish hand simulation as an asset that can be connected to diverse input tracking devices, and seamlessly integrated in game engines for fast deployment in VR applications.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126304783","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 primary goals of this study are to analyze the possible use of virtual reality (VR) as an affective medium and research the relationship between immersion and emotion. To investigate these objectives, we compared two viewing conditions (HMD vs. No-HMD) and applied two types of emotional content (horror and empathy) to examine whether the level of immersion could influence emotional responses. The results showed that viewers who watched the horror movie using HMD felt more scared than those in the No-HMD condition. However, there were no significant emotional differences between the HMD and No-HMD conditions in the movie groups exposed to empathy. Regarding these results, we may assume that the effect of an immersive viewing experience on emotional responses in VR is deeply related to the degree of arousal and strong perceptual cues. The horror movie used in this study included intense visual and audio stimuli found in the typical horror film format. In contrast, viewers experienced less stimulating perceptual input when they are watching the empathetic movie. In conclusion, VR undoubtedly elicits a more immersive experience and greater emotional responses to the horror film. This study has confirmed the efficacy of VR as an emotional amplifier and successfully demonstrated the important association between immersion and emotion in VR.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"371 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121740500","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}

Vibrotactile and auditory feedback have been suggested as additional perceptual cues complementing the visual channel to improve interaction in VR. However, it has rarely been shown that multimodal feedback improves performance or reduces errors during 3D object selection. Only little research has been conducted in the area of proximity-based multimodal feedback, in which stimulus intensities depend on spatiotemporal relations between input device and the virtual target object. In this paper, we analyzed the effects of unimodal and bimodal feedback provided through the visual, auditory and tactile modalities, while users perform 3D object selections in VEs, by comparing both binary and continuous proximity-based feedback. We conducted a Fitts' Law experiment and evaluated the different feedback approaches. The results show that the feedback types affect ballistic and correction phases of the selection movement, and significantly influence the user performance.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114421092","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 designed an experiment which explicitly prevented confounding factors potentially introduced by virtual body ownership and/or agency. The experimental design consisted of two main conditions defining congruent vs incongruent visual and haptic cues. Presence was measured during as well as after exposure. A distance estimation task solely based on motor action and the visually-anchored spatial model of the environment was executed to control for perceptual binding. 56 healthy volunteers were randomly assigned to one of two groups in a single-blind mixed-group design study. The study revealed increased presence for high prediction accuracy and decreased presence for low prediction accuracy, while perceptual binding still occurred. The observed effect sizes were in the medium range. The results indicate a significant correlation between prediction accuracy of haptic information and the perceived realness and presence of a virtual environment which gives rise to a discussion about models for dissociative symptom derealisation.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131254962","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}

Many of the training scenarios for these various fields may require the presentation of realistic interactions with virtual humans. It is thus vital to determine the critical factors of fidelity required in those interactions to elicit naturalistic behavior on the part of trainees. Negative training may occur if trainees are inadvertently influenced to react in ways that are unexpected and unnatural, hindering proper learning and transfer of skills and knowledge back into real world contexts. In this research, we examined whether haptic priming (presenting an illusion of virtual human touch at the beginning of the virtual experience) and different locomotion techniques (either joystick or physical walking) might affect proxemic behavior in human users. The results of our study suggest that locomotion techniques can alter proxemic behavior in significant ways. Haptic priming did not appear to impact proxemic behavior, but did increase rapport and other subjective social measures. The results suggest that designers and developers of immersive training systems should carefully consider the impact of even simple design and fidelity choices on trainee reactions in social interactions.","PeriodicalId":355048,"journal":{"name":"2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132805717","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}
