By the end of 1990 the academy has experienced a remarkable growing in the interest on early design phases pushed by mass customization. In what concerns automation, requirement is a keyword since the detachment in the mechatronic approach is just the design process, although most of the development effort is still directed to the last design phases: optimization and implementation. In general, control and automation designers underestimate requirements elicitation and analysis, mostly by its semiformal nature. That is understandable, since formal approaches are very important to processes that are supposed to be autonomous. Especially in the case where the developer and application environment are disjoints, that is, the domain of users and stakeholders is very distinct from the developer domain, elicitation could become a very complex process. In this work it is presented a systematic approach to requirements management in disjoint domains inspired in the known technique of virtual prototyping that appear in the 2000's. A case study is addressed were a requirement elicitation and analysis is made in the domain of medical (ophthalmologic) surgery. To approximate both domains (Medical and Engineering) it is used a practical reduction of the virtual prototyping techniques that makes the process applicable still keeping its soundness. All data used in this work came from an elicitation done at Santa Luzia Hospital, in Salvador, Bahia, and from the Instituto da Visão, UNIFESP, São Paulo.
