- A 360º overview of the VISIR remote laboratory in a handbookPublication . García-Zubía, Javier; Hernandez-Jayo, Unai; Alves, GustavoThe Virtual Instrument Systems In Reality (VISIR) remote laboratory was considered the best remote laboratory in the world, by the Global Online Laboratory Consortium (GOLC), in 2015. The first operational version of the VISIR remote laboratory was deployed in 2001. It was designed by Ingvar Gus tavsson, with the collaboration of Kristian Nilsson and Johan Zackrisson. Since then, VISIR has been deployed 21 times, in 19 universities, in 14 countries, on five continents. Because of it, there is a very powerful user community that serves thousands of students and is articulated around the VISIR Special Interest Group (SIG) and the VISIR Federation. However, this community of users does not have a unique document that integrates all the knowledge created and needed by the group. This paper describes the first handbook fully dedicated to the VISIR re mote laboratory, aimed at closing that gap.
- Adaptação de Laboratórios Remotos a Cenários de Ensino: Casos de Estudo com VISIR e RemotElectLabPublication . Fidalgo, André V.; Alves, Gustavo R.; Marques, Maria A.; Viegas, Maria C.; Costa-Lobo, Maria C.; Hernández-Jayo, Unai; García-Zubía, Javier; Gustavsson, Ingvar; Alves, Gustavo; Fidalgo, André; Marques, Maria Arcelina; Viegas, Clara; Costa Lobo, Cristina; Garcia-Zubia, JavierOs laboratórios remotos são uma ferramenta tecnológica e pedagógica com uso crescente em todos os níveis de educação, e sua utilização generalizada é uma parte importante do seu próprio aperfeiçoamento e evolução. Este artigo descreve vários problemas encontrados em aulas laboratoriais, em cursos de ensino superior, na utilização de laboratórios remotos baseados em sistemas PXI, utilizando o sistema VISIR ou uma solução alternativa. São identificados e explicados três problemas que foram relatados por professores que deram apoio aos estudantes na utilização dos laboratórios remotos. O primeiro problema prende-se com a necessidade de permitir aos alunos selecionar a localização específica onde um amperímetro deve ser inserido nos circuitos elétricos, mesmo que incorreta, replicando as dificuldades do mundo real. O segundo é causado por falhas de sincronismo quando são necessárias várias medições em intervalos curtos, como no ciclo de descarga de um condensador. E o último problema é provocado pelo uso de um multímetro em modo DC na leitura de grandezas em CA, um procedimento que colide com as definições do equipamento. Todos os cenários são apresentados e discutidos, incluindo a solução encontrada para cada caso. A conclusão que se retira do trabalho descrito é que a área de laboratórios remotos é um campo em expansão, onde a sua utilização prática permite o aperfeiçoamento e a evolução das soluções disponíveis, exigindo uma cooperação e partilha de informação entre todos os intervenientes, i.e. investigadores, professores e alunos.
- Automatic assessment using VISIR-DBPublication . Hernandez-jayo, Unai; Garcia-Zubia, Javier; Cuadros, Jordi; Serrano, Vanessa; Fernandez-Ruano, Laura; Alves, GustavoVISIR is a remote laboratory oriented to analogue electronics. There are several copies of VISIR around the world (Sweden, Spain, Portugal, Costa Rica, Brazil, Argentina, India, Australia, Morocco, …) that are being used by thousands of students. It is well known that VISIR allows teachers and students to create and measure real electrical and electronics circuits through a useful interface and a complex hardware & software platform. But at this moment there is not available at the interface neither offline, any feedback from the VISIR to teachers/students about the performance of the user during the experimentation. This article pre sents the use of the VISIR Dashboard (VISIR-DB) that the teacher can perform to know the achievement of his students using the VISIR remote laboratory.
- VISIR Handbook - Analog Electronics with the VISIR Remote Lab: Real Online ExperimentsPublication . Alves, Gustavo; Unai; Garcia-Zubia, Javier[Preface] Remote experimentation and remote experiments have been around for more than 25 years, being commonly used in universities and other edu-cational institutions. A remote experiment is a real experiment in which the learner is not at the same location of the experiment and the interaction is mediated by the Internet. A remote experiment is a learning tool and its main characteristics are scalability, sustainability, educational quality, and equity. The VISIR Handbook focuses on one particular remote laboratory: Virtual Instruments Systems In Reality (VISIR), which is undoubtedly the best remote laboratory, the most widely used and deployed in more institutions other than the one that developed it, the Blekinge Tekniska Högskola (BTH). This book is a detailed guide to its qualities and capabilities so the reader can get to know it if he or she does not have one or exploit it in depth if he or she already has one. VISIR is almost 25 years old now (1999–2023). It was designed by Professor Ingvar Gustavsson and it focuses on electrical and electronic circuits: assembling, measuring, and analyzing circuits created with real components and wires. From the beginning, Professor Gustavsson shared the design with the academic community. As a result, VISIR is now avail-able in 12 countries and its design and capabilities continue to improve. This book is a compendium of everything that has been developed around the VISIR laboratory, both from a technical and didactic point of view.
