foundation of the IVO (Integrated Virtual Operator) platform which enables
the creation, deployment and execution of context-aware mobile applications
by end-users without programming skills. We use an event-driven workflow
model to describe the behaviour of the applications. Thus, whenever the
defined context occurs, the corresponding workflow immediately starts
reproducing the desired behaviour without the need of user intervention. The
IVO platform comprises two composite tools that provide a visual programming
environment for editing IVOML files. IVOML can be used at runtime in mobile
devices, by providing interpreters that run the applications written with the
composite tools. This allows any created application to be distributed and
executed on mobile devices based on various platforms without the need for
maintaining separate versions. To test the whole platform, an Android and an
iPhone runtime were created which provide the necessary support for the
execution of the applications developed using IVO. Keywords: ubiquitous computing, context-awareness,
mobile devices, XML-based language +: Corresponding author: Valentim
