- Collaboration in 3D virtual worlds : a protocol for case study researchPublication . Cruz, Armando; Paredes, Hugo; Fonseca, Benjamim; Martins, Paulo; Morgado, LeonelThree-dimensional virtual worlds have been growing fast in number of users, and are used for the most diverse purposes. In collaboration, they are used with good results due to features such as immersion, interaction capabilities, use of avatar embodiment, and physical space. In the particular cases of avatar embodiment and physical space, these features support nonverbal communication, but its impact on collaboration is not well known. In this work we present a protocol for case study research and its creation process, which aims to assert itself as a tool to collect data on how nonverbal communication influences collaboration in three-dimensional virtual worlds. We define the propositions and units of analysis, and a pilot case to validate them. Then, two cases are analysed under the created protocol. Most of the propositions found chains of evidences supporting them.
- Development of a mechanical maintenance training simulator in OpenSimulator for F-16 aircraft enginesPublication . Pinheiro, André; Fernandes, Paulo; Maia, Ana Margarida; Cruz, Gonçalo; Pedrosa, Daniela; Fonseca, Benjamim; Paredes, Hugo; Martins, Paulo; Morgado, Leonel; Rafael, JorgeMechanical maintenance of F-16 engines is carried out as a team effort involving 3 to 4 skilled engine technicians. This paper presents the development of a mechanical maintenance simulator for their training. This simulator aims to enable technician training to be enhanced with cooperation and context prior to the training phase with actual physical engines. We describe the requirements that were identified with the Portuguese Air Force, the overall software architecture of the system, the current stage of the prototype, and the outcomes of the first field tests with users.
- Integrating virtual worlds with learning management systems : the MULTIS approachPublication . Morgado, Leonel; Paredes, Hugo; Fonseca, Benjamim; Martins, Paulo; Almeida, Álvaro; Vilela, Andreas; Pires, Bruno; Cardoso, Márcio; Peixinho, Filipe; Santos, ArnaldoLearning Management Systems (LMS) provide minimal support for educational use of virtual worlds. Integration efforts assume the educators are inside the virtual world, providing hooks to services in the external LMS, to setup and manage virtual world activities. We present the inverse approach, enabling educators to setup and manage virtual world activities using the traditional LMS Web interface as an integral part of the overall educational activities of a course. In our approach, the LMS enables the teacher/trainer to setup, control, track, and store virtual world activities and its elements. It is the result of a joint effort by academic and corporate teams, implemented in the Formare LMS for OpenSimulator and Second Life Grid virtual world platforms. We explain how the Multis architecture can be used for integration, with concrete cases, an approach that can be implemented in other LMS and virtual world platforms, to overcome the limitations of existing systems for organizational management of e-learning activities.
- Exploring the usage of 3D virtual worlds and kinect interaction in exergames with elderlyPublication . Paredes, Hugo; Cassola, Fernando; Morgado, Leonel; Carvalho, Fausto de; Ala, Silvia; Cardoso, Francisco; Fonseca, Benjamim; Martins, PauloThe combination of the potentialities of the interactive technologies, like exergames and the emerging motion capture devices with the ability of 3D virtual worlds for socialisation and context, can produce a platform to promote the physical activity of its users, which leverages its potential. The OnlineGym is an exploratory project based on an online 3D virtual worlds platform that allows users to interact with the system through the use of a motion capture device. This paper discusses the chosen technological approaches and the preliminary results of the experiments performed with users.
- Collaboration in 3D virtual worlds: designing a protocol for case study researchPublication . Cruz, Armando; Paredes, Hugo; Fonseca, Benjamim; Martins, Paulo; Morgado, LeonelThree-dimensional virtual worlds (3DVW) have been growing fast in number of users, and are used for the most diverse purposes. In collaboration, 3DVW are used with good results due to features such as immersion, interaction capabilities, use of avatar embodiment, and physical space. In the particular cases of avatar embodiment and physical space, these features support nonverbal communication, but its impact on collaboration is not well known. In this work we present the initial steps for creation of a protocol for case study research, aiming to assert itself as a tool to collect data on how nonverbal communication influences collaboration in 3DVW. We define the propositions and units of analysis, and a pilot case to validate them.
- Integration scenarios of virtual worlds in learning management systems using the MULTIS approachPublication . Morgado, Leonel; Paredes, Hugo; Fonseca, Benjamim; Martins, Paulo; Almeida, Álvaro; Vilela, Andreas; Pires, Bruno; Cardoso, Márcio; Peixinho, Filipe; Santos, ArnaldoThis work further clarifies how the MULTIS architecture can be used for integration of virtual worlds in learning management system (LMS) for organizational management of e-learning activities, as an extension to a previous work published in the proceedings of VEAI 2016. Current LMSs provide minimal support for educational use in an organizational context, and other integration efforts assume that educators are inside the virtual world, accessing the LMS as an external service. Our approach enables educators to set up and manage virtual world activities from within the traditional LMS Web interface as an integral part of the overall educational activities of a course. The MULTIS architecture foresees several alternative communication channels between LMS and virtual worlds, including the spooling of automated clients or “bots” and the flexibility to inject code if necessary and possible. In this work, we detail the application of this architecture and its approach in several sample scenarios, based on previous analysis of integration requirements. It is the result of a joint effort by academic and corporate teams, implemented and tested in the Formare LMS for OpenSimulator and Second Life Grid virtual world platforms.
- Requirements for the use of virtual worlds in corporate training : perspectives from the post-mortem of a corporate e-learning provider approach of Second Life and OpenSimulatorPublication . Morgado, Leonel; Paredes, Hugo; Fonseca, Benjamim; Martins, Paulo; Antunes, Ricardo; Moreira, Lúcia; Carvalho, Fausto de; Peixinho, Filipe; Santos, ArnaldoBetween 2009 and 2011, a joint academia-industry effort took place to integrate Second Life and OpenSimulator platforms into a corporate elearning provider’s learning management platform. The process involved managers and lead developers at the provider and an academic engineering research team. We performed content analysis on the documents produced in this process, seeking data on the corporate perspective of requirements for virtual world platforms to be usable in everyday practice. In this paper, we present the requirements found in the documents, and detail how they emerged and evolved throughout the process.
