Several abstractions have been implemented, making this process simpler, at an affordable cost. Procedures for visualization and controlling of medical images, routinely performed in surgical theatres, were also successfully modeled, including gesture control of radiological images. We have also conducted initial usability testings with users to determine performance measures, the influence of gesture control on perceived usefulness and ease of use of the system. The results show that the participants are able to perform the tasks of search, selection and manipulation of 2D images and 3D models, quickly and accurately, demonstrating the usefulness of the system as a possible effective and competitive alternative, to the traditional use of the negatoscope, for gesture based interactive control of medical images.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121993918","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}

Thus, large companies have been investing in the development of tools that help both the risk perception and training of workers in their basic tasks. This paper presents the development of an immersive simulator and its application for risk analysis. The unique feature of our simulator is that it runs on a regular smartphone coupled to a physical plug-in designed to allow immersive stereo viewing. The system usability was tested with user experiments, being well received. This design provides low cost and excellent scalability as it is based on self owned devices and off-the-shelf add-ons.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127784738","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}

For this, we apply the Continuous Time Recurrent Artificial Neural Network and the genetic encoding proposed in [1] [2]. However, we use a new sensorial description, which consists in captured images by a virtual camera, evolving an artificial visual cortex. The experiments show that the agents are able to navigate in the environment and to find the exit, in a non-programmed way, using only the visual data passed to the neural network. This has the flexibility to be applied in various environments, without displaying a forced tendency by a possible behavioral modeling as in other techniques.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"431 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129656170","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}

However, most of the medical applications have volumetric data to be visualized. Therefore, it is desirable to the medical AR systems to provide the visualization of these volumes into the real scene in real-time. In this paper we introduce a real-time semi-automatic approach for on-patient medical volume data visualization. It is proposed in a marker less augmented reality (MAR) environment and the medical data consists of a volume reconstructed from 3D computed tomography (CT) image data. A 3D reference model of the region of interest in the patient is generated and tracked from the Kinect depth stream. From the estimated camera pose, a volumetric medical data can be displayed to a physician inside the patient's anatomy at the location of the real anatomy. We evaluate the use of the named standard volume rendering techniques in the context of a MAR environment. The results obtained so far show that these techniques can be applied in this scenario in real-time.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122827125","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 scenario with several sources of information, the obtaining of relevant and timely information has become primordial to ensure the effectiveness of mobile solutions that help the user to locate and identify points of interest (POI ) on demand. Thus, this paper presents a layered architecture for the structural organization of information consumed by mobile navigation applications, providing a personalized on-demand by user about what information on points of interest should be displayed in the AR application interface. The layers are presented and their performance in a situation of POI search is discussed in details.

Morimoto","doi":"10.1109/SVR.2014.32","DOIUrl":"https://doi.org/10.1109/SVR.2014.32","url":null,"abstract":"Realistic makeup simulation can be used to create interactive virtual environments where users can try makeup products in a fast, low-cost and flexible way. Most existing makeup simulators are not appropriate for interactive applications because they don't allow the realistic application of specific products interactively or are based on fixed makeup styles that depend on the same pose and lighting conditions of predefined makeup templates. This paper introduces a new method for makeup simulation that receives a picture with a clean (no makeup) face, and decomposes the facial region into several frequency bands. Each band is processed individually to conceal or enhance facial texture and color features that can be affected by makeup. A specific makeup product is defined by a set of properties that change the texture and color features. To allow the interaction among several makeup products, the method uses a layered representation that can mimic the application of a sequence of products. We present a real-time implementation of the method that simulates the application of foundation, eye shadow and lipstick. The software was developed in C++ and can process one high resolution (1018×990) facial image in about 80 ms and one low resolution (640×480) in about 30ms.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127850309","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 use Proportional-Derivative (PD) Controllers to mimic the characteristics of angular joints, and deal with the equilibrium through a method that uses the transpose of the Jacobian matrix that relates the angular and linear momentum at the Center of Mass (COM) of the character's body to the corresponding quantities at all its links, which are treated as end effectors. Also, we propose a contact model for treating the interaction between the feet and the ground that confers great stability to the character and makes it easier for the controller and for the starting of the simulation. It also makes it convenient for the animator to adjust the model so as to consider a trade-off between more physical realism and more stability. The system does not use optimization and is simple to implement. The robustness of the controller is demonstrated through a series of tests.","PeriodicalId":291858,"journal":{"name":"2014 XVI Symposium on Virtual and Augmented Reality","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116206479","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}
