It has been used in the field of maintenance in order to show the user the operations he has to perform. Our goal is to go one step further so that our system is able to detect when the user has performed a step of the task. It requires some understanding of what is occurring and where objects are located in order to display correct instructions for the task. This paper is focusing on using an intermediate computation result of the usual augmented reality process, which is the pose computation: we propose to use the transformation matrix not only for objects pose estimation, but also to characterise their motion during an assembly task. With this matrix, we can induce spatial relationship between assembly parts and determine which motion occurs. Then we analyse translation and rotation parameters contained in the transformation matrix during the action. We demonstrate that these data correctly characterise the movement between object's fragments. Therefore, by analysing such a matrix, not only we can achieve the required registration step of the augmented reality process, but we can also understand the actions performed by the user.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"387 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123196603","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 use case scenario is highly collaborative and incorporates a wide variety of interaction tasks, such as: collaborative handling, manipulation, removal, placement and laying of carbon fabric composite parts. A Kinect sensor and a Head Mounted Display (Oculus Rift) are employed as 3D User Interfaces for interaction, immersion and skeletal tracking of the user motion. In this paper, particular emphasis is given to the various interaction techniques used to facilitate implementation of virtual Human-Robot Collaboration (HRC). The collaborative tasks are principally executed with contactless, natural and direct interaction. In addition, two novel interaction metaphors were developed. The real fabric laying task and the backing film removal task are reproduced in the VE with the implementation of the \"follow-my-hand\" technique; the user has to follow with his hand a virtual hand-like index (guide) that moves along a predefined pattern. Preliminary findings concerning the effectiveness of HRC modelling tasks are positive, and are briefly discussed.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126046356","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 system uses an Oculus VR for visualizing the world, a Leap Motion for interaction with the environment and an optional Arduino with celphone vibrators for haptic feedback. We do realtime clay deformation by extruding / compressing triangle vertices on a radius of influence and interact with the world by pressing buttons with the user's index finger.

Head-mounted displays (HMDs), however, use displays and optical elements in front of a user's eyes, which often do not natively support a wide field of view to stimulate the entire human visual field. Such limited visual angles are often identified as causes of reduced navigation performance and sense of presence. In this paper we present an approach to extend the visual field of HMDs towards the periphery by incorporating additional optical LED elements structured in an array, which provide additional low-resolution information in the periphery of a user's eyes. We detail our approach, technical realization, and present an experiment, in which we show that such far peripheral stimulation can increase subjective estimates of presence, and has the potential to change user behavior during navigation in a virtual environment.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125762724","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}

These two cameras have parallel optical axis. It is well know that if cameras converge, then it produces distortions called vertical parallaxes. These distortions are supposed to stress visual system, but we do not know the effect on perception. In this article, we will test if these vertical parallaxes can improve shape perception. We found out that vertical parallaxes does improve shape perception, but the effect is decreased when the object is far from the user because when the cameras converge far away it get closer to a parallel configuration.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122087295","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 study, a system was developed that alternates user's body scheme and motion mapping in real-time when the user interacts with virtual contents. User arms and hands are tracked and mapped into several virtual arms instances that were generated from user's first point of view (FPV), and are deviated from his physical arms position at different angles. Participants reported a strong sense of body ownership toward the extra arms after interacting and holding virtual contents using them. Our finding is body ownership perception can be altered based on the condition used. Also, one interesting finding in this preliminary experiment is that the participants reported strong ownership toward the arm that actually is not holding the virtual object. This study contributes in the fields of augmented bodies, multi-limbs applications, as well as prosthetic limbs.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178655","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}
