Although training and learning environments are classical applications of virtual reality, the design of these environments is generally ad hoc, hence requiring the intervention of programmers whenever a modification of the pedagogical scenario is required. In this paper, we propose a methodology to design virtual environments which can be adapted by teachers to implement different scenarios according to the level of the trainees and to the pedagogical objectives. Current demonstrators include a windmill with three different learning situations: simulator, safety training and preventive maintenance training.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"13 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":"116844646","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}

It is part of the CIGALE interdisciplinary project involving researchers in the fields of linguistics, digital arts and computer science, as well as actors and professors. Several experiments of improvisation conducted with actors through computer-mediated interactions help in characterizing specific dynamics of gestures, recurrent behaviors and gestural patterns. We extract specific descriptors of movement and behaviors that will drive the improvisation. The virtual actor is able to improvise and generate its gestures using a finite state machine that triggers three main behaviors according to the actor's body posture and arm movements: the virtual actor can mime in real-time the real actor, it can propose expressive or linguistic gestures from four MoCap databases, or it can generate a new gesture using a genetic algorithm. A first installation experienced by the participants during an international art festival, shows they are able to improvise fluently with the virtual actor in an expressive dialogue.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"1 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":"128462848","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}

Growing evidence in the medical literature suggests that virtual reality is a very potent and effective way of creating distraction. In turn, distraction has been shown to reduce pain and anxiety in children who are receiving painful medical procedures. The pediatric population offers quite a challenge when it comes to pain control, especially the pain caused by medical procedure. Anxiety and anticipation greatly modulates pain perception and can often jeopardize a treatment if a child's collaboration cannot be obtained. With those premises in mind, our team is trying to create an efficient virtual reality game for distracting kids from their pain. The DREAM game has been tailored for the very specific needs and characteristics of our target population. The experience is optimized for the oculus rift and the controls have been simplified to work in various medical settings with minimal preparation time. Our main concern was to create a game that delivers a potent distractive effect while inciting almost no side effects or cyber sickness. The DREAM project is currently being tested on children with burn injuries. The objective of this short paper is to present the methodology used to validate our hypotheses.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"41 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":"125539868","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}

Automation in industries reduced the human effort, but still there are many industries in which human have to do complex and repetitive tasks manually. The society/companies have to pay attention on this issue due to the new laws on penibility or repetitive tasks. The objective of this paper is to experimentally validate a new dynamic muscle fatigue model using electromyography (EMG) and Maximum voluntary contraction (MVC). A new model is developed by introducing a co-contraction factor 'n' in the Ruina Ma's dynamic muscle fatigue model. The experimental data of ten subjects are used to analyze the muscle activities and muscle fatigue during extension-flexion motion of the arm on a constant absolute value of the external load. The findings for co-contraction factor shows that the fatigue increases when co-contraction area decreases. The dynamic muscle fatigue model is validated using the MVC data, fatigue rate and co-contraction factor of the subjects.","PeriodicalId":113875,"journal":{"name":"Proceedings of the 2016 Virtual Reality International Conference","volume":"70 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":"114146612","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}

Some existing methods are still time consuming and limited in number of elements by algorithm complexity. We present in this paper the HEML (Hyper-Elastic Mass Links) method, which is generic, fast and realistic. We demonstrate on a mesh issued from real patient (MRI scan image data) that real-time computation for visual display can be handled by the method.
