Visualizing structure and quality properties of Smart Spaces

Smart Spaces embedded into our surroundings are dynamic in nature; variable types and amount of services and applications are provided by a set of interoperable devices and systems that are joining and leaving a space every now and then. Thus, the structure, functionality and quality properties of the space are changing at every turn. In order to understand, what devices/systems there are in the space, what applications and services the space provides and what is the quality level of these services, application developers and smart space users need to have an assistant that helps them in figuring out these things. On this account, we use a visualization tool IQVis for illustrating how the run-time properties of a smart space are changing in time. Application developers can use the tool for seeing how an application behaves in a real situation. A user of a smart space can use the quality information provided by the IQVis tool, e.g., on the screen of his/her mobile phone, for adapting his/her profile/actions. The use of IQVis will be exemplified by a smart greenhouse scenario, a case study implemented in laboratory settings.
