Case Study of the OMiSCID Middleware: Wizard of Oz Experiment in Smart Environments

This paper presents a case study of the usage of OMiSCID 2.0, the new version of a lightweight middleware for ubiquitous computing and ambient intelligence. The objective of this middleware is to bring Service Oriented Architectures to all developers. After comparing to available solutions, we show how it integrates in classical workflow without adding any constraint on the development process. Developers only need to use a library available in widely used programming languages (C++, Java and Python). Then, the basics of OMiSCID and a brief technical description are described as its User Friendly API. This API makes it straightforward to expose, look for or send messages between software components over a network. The added value of the proposed middleware has already been experienced in international research projects. This paper demonstrates its effect in cutting down development time, improving software reuse and easing redeployment in the context of a Wizard of Oz experiments in intelligent environments.
