Acesso a laboratórios remotos via ambientes imersivos acesso remoto a um multímetro

Recentemente, tem-se assistido à utilização de ambientes imersivos 3D em vários domínios tais como: actividades empresariais, educativas, lúdicas, entre outras devido à expansão do Second Life. A finalidade deste conceito é oferecer aos utilizadores um acesso alternativo a valências existentes no mundo real, a partir de um computador ligado à Internet. Uma aplicação prática pode ser a sua utilização em laboratórios remotos, com a finalidade de controlar remotamente instrumentos de medição, a partir de um ambiente imersivo. Para isso, o mesmo deve permitir a construção de um laboratório virtual e respectivos instrumentos, também virtuais. Este tipo de solução é viável, devido a existirem dispositivos com interfaces de acesso remoto, e ambientes 3D desenvolvidos em linguagens de programação que possuem bibliotecas de código para protocolos de redes de computadores. A finalidade deste trabalho é desenvolver uma metodologia de acesso remoto, a instrumentos de medição em laboratórios de electricidade e electrónica, usando ambientes imersivos 3D. Como caso de estudo, o instrumento utilizado é um multímetro, controlado remotamente a partir de uma reprodução num mundo virtual, construído no ambiente 3D Open Wonderland. Nessa reprodução virtual, numa primeira fase, só serão disponibilizadas para medição, um conjunto limitado das variáveis eléctricas passíveis de medir através do multímetro seleccionado.

Adapting remote labs to learning scenarios: case studies using VISIR and RemotElectLab

Remote laboratories are an emergent technological and pedagogical tool at all education levels, and their widespread use is an important part of their own improvement and evolution. This paper describes several issues encountered on laboratorial classes, on higher education courses, when using remote laboratories based on PXI systems, either using the VISIR system or an alternate in-house solution. Three main issues are presented and explained, all reported by teachers, that gave support to students' use of remote laboratories. The first issue deals with the need to allow students to select the actual place where an ammeter is to be inserted on electric circuits, even incorrectly, therefore emulating real-world difficulties. The second one deals with problems with timing when several measurements are required at short intervals, as in the discharge cycle of a capacitor. In addition, the last issue deals with the use of a multimeter in dc mode when reading ac values, a use that collides with the lab settings. All scenarios are presented and discussed, including the solution found for each case. The conclusion derived from the described work is that the remote laboratories area is an expanding field, where practical use leads to improvement and evolution of the available solutions, requiring a strict cooperation and information-sharing between all actors, i.e., developers, teachers, and students.
