Previous issue date: 2009-03-31 / Fundação de Amparo à Pesquisa do Estado do Amazonas / Work and learning built individually and in groups took a new and definitive impulse from popularization of software tools that currently compose web-based virtual environments. After a time of reckoning and appropriation of these resources, work, teaching, learning and social relations started to demand that virtual environments cannot yet answer, partially due to need of conformation by some of these environments to certain functional aspects maintained mainly by tradition. A possible strategy to deal with this problem is to devise and to develop flexible environments to support cooperative activities, given users a better balance between supporting tools and goals and profiles of participants in a specific activity. This work is part of a multi-institutional effort on the area where, from conceptual elements defining an innovative and simple approach to development of virtual environments, it is reported the organization, modeling and implementation of an instance of this kind of environment. The resulting prototype, currently in use at UFAM, was built using Moodle as development and evaluation platform. / O trabalho e a aprendizagem construídos individual e coletivamente tomaram novo e determinante impulso a partir da disseminação das ferramentas de software que atualmente compõem os ambientes virtuais baseados na Web. Após um período de reconhecimento e apropriação desses recursos, o trabalho, o ensino, a aprendizagem e as relações sociais como um todo passam a apresentar demandas que os ambientes virtuais ainda não conseguem atender, em parte devido à conformação desses ambientes a certos aspectos funcionais mantidos principalmente por tradição. Uma estratégia possível para tratar esse problema é a concepção e desenvolvimento de ambientes flexíveis para apoiar a realização de atividades cooperativas, propiciando aos usuários uma melhor sintonia entre ferramentas de apoio e os objetivos e os perfis dos participantes de uma determinada atividade. O trabalho aqui descrito faz parte de um esforço multi-institucional de pesquisa no tema, onde, a partir dos elementos conceituais que definem uma abordagem de inovadora simplicidade à concepção e desenvolvimento de ambientes virtuais, é relatada a organização, modelagem e implementação de uma instância desse tipo de ambiente. O protótipo resultante, atualmente em plena utilização na UFAM, foi construído utilizando o Moodle como plataforma de desenvolvimento e avaliação.

Implementation and Analysis of Co-Located Virtual Reality for Scientific Data VisualizationJordan M McGraw (8803076) 07 May 2020 (has links)
<div>Advancements in virtual reality (VR) technologies have led to overwhelming critique and acclaim in recent years. Academic researchers have already begun to take advantage of these immersive technologies across all manner of settings. Using immersive technologies, educators are able to more easily interpret complex information with students and colleagues. Despite the advantages these technologies bring, some drawbacks still remain. One particular drawback is the difficulty of engaging in immersive environments with others in a shared physical space (i.e., with a shared virtual environment). A common strategy for improving collaborative data exploration has been to use technological substitutions to make distant users feel they are collaborating in the same space. This research, however, is focused on how virtual reality can be used to build upon real-world interactions which take place in the same physical space (i.e., collaborative, co-located, multi-user virtual reality).</div><div><br></div><div>In this study we address two primary dimensions of collaborative data visualization and analysis as follows: [1] we detail the implementation of a novel co-located VR hardware and software system, [2] we conduct a formal user experience study of the novel system using the NASA Task Load Index (Hart, 1986) and introduce the Modified User Experience Inventory, a new user study inventory based upon the Unified User Experience Inventory, (Tcha-Tokey, Christmann, Loup-Escande, Richir, 2016) to empirically observe the dependent measures of Workload, Presence, Engagement, Consequence, and Immersion. A total of 77 participants volunteered to join a demonstration of this technology at Purdue University. In groups ranging from two to four, participants shared a co-located virtual environment built to visualize point cloud measurements of exploded supernovae. This study is not experimental but observational. We found there to be moderately high levels of user experience and moderate levels of workload demand in our results. We describe the implementation of the software platform and present user reactions to the technology that was created. These are described in detail within this manuscript.</div>
