Though quite a mature field, several scientific problems remain open and particularly the reduction of drift. Drift is inherent to SLAM since the task is fundamentally incremental and errors in model estimation are cumulative. In this paper we suggest to take advantage from sparse but accurate knowledge of the environment to periodically reinitialize the system, thus stopping the drift. As it may be of interest in a Augmented reality context, we show this knowledge can be propagated to past estimations through bundle adjustment and present three different strategies to perform this propagation. Experiments carried out in an urban environment are described and demonstrate the efficiency of our approach.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126797601","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}

More specifically, a weightlifting athlete attempt is monitored, helping any coach to train athletes as she/he prefers. Our aim is to detect, collect and extract every useful data which give insight about the body technique during the weightlifting attempt and therefore make all the necessary calculations. A Kinect sensor is used for tracking the weightlifter and collecting depth data during the attempt. Afterwards, data are processed, so that useful information is extracted. In addition, after any attempt, data can be saved and loaded at any time. 2D and 3D graphs are used to illustrate the relevant information. Finally, two attempts can be loaded in parallel for the comparison between two different athletes or between a new and an old registered attempt, giving the ability for matching and correcting different techniques.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130557637","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 introduce in this paper a new entity, the Shell, which aims at abstracting an actor from its embodiment in the virtual world. Thus, using this entity, users and virtual agents are able to collaborate in the same manner during the training. In addition to the embodiment's control, the Shell gathers and carries knowledge and provides interaction inputs. This knowledge and those inputs can be accessed and used homogeneously by both users and virtual agents to help them to perform the procedure. In this paper, we detail the knowledge mechanism of the Shell as this knowledge is a crucial element for both collaboration and learning in the CVET context. Furthermore, we also validate our exposed model by presenting an operational implementation in an existing CVET and discuss of its possible usages.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129654875","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}

Taking the robot's gaze as both metaphor and more literally, I explore how seeing ourselves mediated by technology as an image may be a useful endeavour in highlighting our hybridity. Framing this discussion is a consideration of the image in theological terms, which is a significant undertaking, given that the human is made in the image of God, the robot in the image of the human, and yet, in the robot's gaze, we are imaged by the robot. Is it possible to reconcile these interpretations?","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811780","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}

Virtual reality (VR) training simulators can reduce this training time; however, the current simulators are also quite expensive. Therefore, we propose a low-cost simulation of minimally invasive surgery and evaluate its feasibility. Using off-the-shelf hardware and a commercial game engine, a prototype simulation was developed and evaluated against the use of a surgical robot. The participants of the evaluation were given a similar exercise to test with both the robot and the simulation. The usefulness of the simulation to prepare the participants for the surgical robot was rated \"useful\" by the participants, with an average of 3.1 on a scale of 1 to 5. The low-cost game controllers used in the prototype proved to effectively simulate the controls of the surgical robot. Another test was carried out to determine the benefits of various stereoscopic displays for this simulation. This test did not show significant improvements compared to a regular display but indicated that a mobile stereoscopic display might be the most suitable option for a low-cost simulation of robotic surgery.","PeriodicalId":308845,"journal":{"name":"Proceedings of the Virtual Reality International Conference: Laval Virtual","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124076893","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}
