abstract = {Nowadays virtual, remote and hybrid (with both virtual and real remote components) laboratories depend on a large stack of technologies, and are almost always web-based. However, still today those laboratories which require relatively advanced graphics (3D or even 2D graphics) often rely on non-standard components and browser plugins, such as Adobe Flash or Java Applets. These components were necessary because of the severe limitations that standard Web technologies have traditionally had in regard to graphics and RIAs (Rich Internet Applications). This paper analyzes two of the most common non-standard technologies that are still used today in remote laboratories. It also proposes two alternatives which make use of modern Web technologies (Canvas and WebGL). Additionally, it illustrates one of the proposed alternatives (WebGL) with an example: Weblab-FPGA-Watertank, a hybrid laboratory implemented at the University of Deusto under the Weblab-Deusto RLMS (Remote Laboratory Management System), which lets users program a real FPGA device remotely to control a virtual environment. Users require only an up-to-date browser and require no plugins whatsoever. The fully-featured virtual environment is rendered through WebGL. Finally, conclusions are drawn from the analysis and from the WebLab-FPGA-Watertank experience.

abstract = {A remote laboratory is a software and hardware tool which enables students to use real equipment -located in an educational institution- through the Internet. This way, students can experiment as if they were using the laboratories with their own hands. There are usually two approaches when designing remote laboratories: relying on small, inexpensive devices that can be deployed anywhere or relying software rich software infrastructures that support high load of users, providing panel administration, access to other institutional servers (e.g. directories such as Lightweight Directory Access Protocol “LDAP”), etc. With distributed remote laboratory architectures, it is possible to have the laboratory server on the former approach, but the management usually relies on the latter. In certain entities, such as secondary schools or farm schools, they may not be willing to buy and maintain a dedicated server for remote laboratories, and therefore the former approach is more adequate. However, a tradeoff is being made between management capabilities and how easy is to deploy the system. This contribution shows how federation could help in solving this tradeoff, and it uses a real fish tank remote laboratory as a case study.
