Many Augmented Reality applications require interaction, such as selection and 3D pose manipulation. One way to perform intuitive, high precision 3D pose manipulation is by direct or indirect mapping of device movement. There are two approaches to device movement interaction; one fixes the virtual object to the device, which therefore becomes the pivot point for the object, thus makes it difficult to rotate without translate. The second approach avoids latter issue by considering rotation and translation separately, relative to the object's center point. The result of this is that the object instead moves out of view for yaw and pitch rotations. In this paper we study these two techniques and compare them with a modification where user perspective rendering is used to solve the rotation issues. The study showed that the modification improves speed as well as both perceived control and intuitiveness among the subjects.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129119713","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}

An essential part of most VR systems is stereoscopy. From perceptual research, it is known that stereoscopic perception deteriorates with age [Garnham and Sloper 2006]. As indicator for stereoscopic perception, the authors of this and further studies used stereo acuity, i.e. the smallest disparity difference detected by the visual system. Norman et al. [2000] showed that the declined stereo acuity in older humans can cause these users to perceive less depth in random-dot stereograms. Since VR applications for rehabilitation are advancing, one can expect increasing numbers of elderly users. However, up to now it is unclear whether the age-specific changes in stereoscopic perception might impair the use of VR applications for older people. In our study, we presented stereoscopically rendered virtual objects. The primary aim of this study was to examine possible age differences in fusion range, relative and absolute distance perception, and visual fatigue. Here, we present results of the two tasks concerning distance perception.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123122525","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 several factors have been identified in the past that could explain small portions of this effect, the main causes of these perceptual discrepancies still remain elusive. One of the factors that has received less attention in the literature is the amount of blur presented in the visual imagery, for example, when using a head-mounted display (HMD). In this paper, we analyze the impact of the visual blur effects depth-of-field and motion blur in terms of their effects on distance and speed estimation in IVEs. We conducted three psychophysical experiments in which we compared distance or speed estimation between the real world and IVEs with different levels of depth-of-field or motion blur. Our results indicate that the amount of blur added to the visual stimuli had no noticeable influence on distance and speed estimation even when high magnitudes of blur were shown. Our findings suggest that the human perceptual system is highly capable of extracting depth and motion information regardless of blur, and implies that blur can likely be ruled out as the main cause of these misperception effects in IVEs.","PeriodicalId":396801,"journal":{"name":"Proceedings of the 22nd ACM Conference on Virtual Reality Software and Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121800362","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}
