Refining beyond the essentially different phases as discussed in the previous sections,
the design of a smart space ecology does not happen in one step, but consists
of the design of the components (i.e., devices, sensors, actuators, single device
applications) for use in the environment, enabling design, and the design of
the functional environment, local design. While the enabling design will typically
be performed by professionals as part of their product development, local design
can be performed also by the end user, tailoring his environment and combining
the functionality of the enabled products, as exemplified by the configuration task
in the previous paragraph. We coin this to be the Ecological Approach to Smart
Environments (EASE).
