In these phases, developers record information necessary for properly understanding the nature of the systems under consideration. We consider a particular type of system, named Remote Lab that allows both teachers and students to perform real ex- periments over the internet and we focus on Virtual Instru- ment Systems in Reality (VISIR). We describe a summarized web interface of VISIR using the Unified Modeling Language (UML). Our case study aims at identifying the requirements of VISIR and at creating a set of UML diagrams that succinctly provide enough infor- mation to both developers and users so that they acquire enough information for building a general understanding of it. Additionally, we provide elements for extending UML to better support further user interface development in VISIR.engRemote labsUMLRLsVISIRWeb PagesActivity and Use Case Diagramjournal article10.3991/ijoe.v12i06.5707
