There are several theoretical paradigms, frameworks and technologies that appears promising in helping us to obtain the needed increased efficiency to ease the demographic related problems we are facing as discussed under the background and motivation section.

If we start from the top of the theoretical pyramid, the pervasive computing paradigm is more of a way of thinking interaction and computer support, than it is a well-defined computer science area. The thoughts and ideas behind this paradigm constitutes the building blocks of the OpenCare Project. Both with regards to pervasive technologies like mobile devices, WiFi, Bluetooth, NFC (Near Field Communication), RFID (Radio Frequency Identification), speech technology, AI (Artificial Intelligence), middleware and other standards and technologies, but especially on the conceptual level.

On the next level, we have the concept of pervasive healthcare, which might be considered a subset of pervasive computing within the healthcare sector. That is, pervasive computing applied to the healthcare domain.

Finally assisted living is the last conceptual framework and research area, which is pervasive healthcare at work for the end-users (in some cases considered patients) in their homes.
The OpenCare Project is a framework for building assisted living prototypes and applications.
