Abstract
This demonstration proposal aims to present a 3D multi-user training simulator, developed in the 3D Open Simulator virtual world platform, in order to enable the practice and training of mechanical maintenance for F-16 engines, specifically the installation of a Pratt & Whitney F100 engine in a F-16 aircraft - a process that requires three skilled engine technicians to do a set of cooperative execution tasks. The main purpose of the simulator is to provide trainees and trainers with more opportunities to conduct training, enabling technician training to be enhanced with cooperation and context prior to the training phase with actual physical engines. In this proposal, we describe the architecture of the system and the sample simulation tasks.

Abstract
In this paper, we present the user experience design of Young Europeans for Democracy (YED) serious application. Facing the actually need to support young citizens understanding and participation in Europe, schools have a key role on European studies integration. Accordingly to the growing opportunities of applying technology for training and education, we propose a serious application in a open-source 3D Virtual World environment solution, adopting a problem-based learning approach, role-playing dynamics and group work tasks. The main goal was to design a meaningfully user experience, increasing the students motivation and engagement for learning different knowledge on the topics of European Studies. Some preliminary results are presented, based on participatory observation within the use of the serious application.

Abstract
Mechanical maintenance of F-16 engines is carried out as a team effort involving 3-4 skilled engine technicians, but the details of its procedures and requisites change constantly, to improve safety, optimize resources, and respond to knowledge learned from field outcomes. This provides a challenge for development of training simulators, since simulated actions risk becoming obsolete rapidly and require costly reimplementation. This paper presents the development of a 3D mechanical maintenance training simulator for this context, using a low-cost simulation platform and a software architecture that separates simulation control from simulation visualization, in view of enabling more agile adaptation of simulators. This specific simulator aims to enable technician training to be enhanced with cooperation and context prior to the training phase with actual physical engines. We provide data in support of the feasibility of this approach, describing 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.

Abstract
The 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.

Abstract
This paper is about the development of 3D simulators for supplementary instruction in professional training with complex learning tasks and material, human and economic constraints. We present a theoretical framework describing and explaining how a simulator can support the fundamental interaction dynamics in learning settings (interaction with reality, with others and with the learner himself. We describe the development of an actual 3D simulator (for installing the engine in an F-16 fighter aircraft) and present its next phases. We discuss how our theoretical framework fits and explains the development phases of a 3D simulator to meet the intended learning outcomes and how it can help in the development of simulators with similar purposes.
