Communication and connectivity between devices and services in AAL domains.
An AAL solution that is intended to provide effective support to an older user and
to his or her caregivers, and also to adapt itself to the changing needs of the user
throughout his or her life, needs to be constructed as a modular and easily
reconfigurable composition of multiple applications and services.
Integration of services and applications in a customized package for a specific user
should in particular address the following dimensions:
presentation integration of relevant information through a single interface;
•
data integration allowing aggregation and understanding of data by relevant
applications and services;
•
process integration to support different sequences of tasks or steps that are
relevant to the user as an individual, but also as a member of a team in a care
plan.
•
There are also several possibilities for feedback loops which will also vary
between instances of system. Where relevant, some PAN or LAN devices might give
immediate feedback, e.g. an alarm, to the user and also pass on the alarm to relevant
services or care givers. Other systems will use the application-hosting device for
immediate feedback or applications based on information sent by one of the services in
the WAN. All this should lead to a seamless interoperable set of systems and services
as shown in Figure 11.
