This work presents a comparison between seven algorithms, with different strategies to tackle rigid registration tasks. We focus on the frame-to-frame problem by using both point clouds and a RGB-D video stream in the experimental results. The former, is considered under different viewpoints, with the addition of outliers and noise. Once the ground truth rotation is provided, we discuss four different metrics to measure the rotation error in this case. The video sequence with depth information is segmented to get the target object. Next, the registration algorithms are applied and the average root mean squared error is computed. Since the ground truth is not available in this case, we develop a superposition strategy to visually check performance of the algorithms. Besides, we analyse the robustness of the techniques against spatial and temporal sampling rates.","PeriodicalId":371182,"journal":{"name":"2017 19th Symposium on Virtual and Augmented Reality (SVR)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129905936","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 used a Deep Neural Network model to solve both problems. For classification, we used a Softmax regression and cross entropy loss to train the network. To play the game, we used a Q-Learning adaptation for Deep Learning to train the autonomous agent. In both cases, the input was only the pixels of an image. We show that this single network architecture is suitable for the classification task and is capable of playing the 3D game. This result gives us an insight into the possibility of a general network architecture, capable of solving any kind of problems, regardless of the learning paradigm.","PeriodicalId":371182,"journal":{"name":"2017 19th Symposium on Virtual and Augmented Reality (SVR)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134167171","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 experiences can be augmented by the use of haptic systems, able to provide sense of touch in virtual objects. The anesthesia procedure is present in all surgeries to keep stable the patient physiology. The use of VR based simulators for anesthesia training can allow decreasing of costs, reduction of risks and avoid the practice in real patients without previous practical experience. The objective of the present work was the modeling of a computer based simulator for the training of interns in regional anesthesia with focus on epidural and spinal anesthesia. Meetings with interns in anesthesiology, lecturers and practitioners were necessary to define the system requirements. It resulted in a diagram with the activities present in the procedure and necessary to the learning process. The virtual environment and some activities were implemented with the Unity 3D engine. Tasks that demanded force feedback were proposed to be used with the PHANToM® OMNI device and the software libraries integrated with this engine.

Based on principles of a serious game, the training environment aims to condition the patient to use a prosthesis before it is manufactured. Studies show that the time of adjustment for use of a real prosthesis is considerably high. This often brings immense dismay to those patients who are already psychologically depressed. Thus, the project presented here aims to provide a more attractive and stimulating environment, to motivate users during their adaptation period. In addition, traditional prostheses are very expensive and difficult to access for the neediest population. Therefore, this project aims to produce prosthesis through 3D printers, aiming at reducing costs. For this, the virtual game environment presents the prosthesis to be manufactured with the option of resizing it, based on reactions to the serious game and anatomical formations of the amputee. Finally, in the training environment, the creation of facilitating elements in the process of rehabilitation and adaptation to the prosthesis is sought, through simulations of real-life situations by means of Virtual Reality techniques.","PeriodicalId":371182,"journal":{"name":"2017 19th Symposium on Virtual and Augmented Reality (SVR)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116087635","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}
