SENIOR SITUATION-AWARE
AMBIENT INTELLIGENCE
FRAMEWORK
In a typical data processing scenario, informa-
tion from various sources like sensor devices,
medical devices, care and nursing data and patient
records have to be handled. To allow the integra-
tion of different data sources and to avoid problems
concerning third party data, a Data Abstraction
Layer (DAL) is used. Purpose of the DAL is to
abstract from hardware specific communication
infrastructure and protocols and to integrate third
party data from nursing homes and care institu-
tions. The DAL can be compared to the Context
Sensing Tier mentioned in (Kurschl, Mitsch, &
Schoenboeck, 2008) and is mainly responsible
for data storage, integration and pre-processing.
Typically, sensors use their own proprietary data
formats, and pull (poll data on demand) or push
(receive data periodically) based approaches for
getting data. This causes problems when process-
ing data from different sources. Transforming the
data into a uniform and easy processable repre-
sentation, like RDF data triples, solves this prob-
lem. Before the transformation, additional pre-
processing steps, like removing noise or checking
Various stakeholders with different views and
needs are affected by AAL applications. The most
important stakeholders are the intended users, re-
spectively elderly people. Caregivers or relatives
want to make sure that the care dependent person
gets twenty-four-seven care and that in case of an
accident or illness proper actions are taken. To
achieve this goal, various devices (stove sensor,
light sensors, tracking sensors, sensors measuring
vital signs) and user interfaces (displays, inter-
coms, etc.) are available on the market and can be
assembled to an AAL equipped environment. The
situation-aware ambient intelligence framework
(SENIOR) provides concepts for defining situa-
tions based on ontologies, as well as (proactive)
situation detection and analysis and therefore en-
ables the logical connection of all devices. Figure
10 shows the blueprint of the SENIOR framework
and will be explained hereinafter.
