The Activity Monitor is an easy-to-configure context-aware mobile application, capable of estimating and evaluating the user’s activity. It
relies on fusion strategies for movement and location estimation, which combine acceleration and radio data from in-device and external
sensors. The final objective of the Activity Monitor is to deliver adequate context-aware notifications in order to make the user aware of his
level of activity. It has been integrated as part of a light framework aiming at providing a set of standard features to build context-aware
mobile applications in order to support and accelerate their design and development life cycle.
1 sensing subsystem 2 management subsystem
Built on the sensing modules,
the Management Subsystem
offers a set of application-
independent facilities to deal
with context processing, built as
services to be used by the
applications deployed on top of
it. Horizontal services are, for
example, related to offering
seamless position estimation
(handling handovers from GPS
when outdoors to WiFi, ZigBee
and Bluetooth-based
localization systems when
indoors), physical detection of
tagged Points of Interest (which
can be dynamically discovered
by using wireless technologies
or by previous location-aware
registration in the PoI Application
database), image-based

By using the Points of Interest (PoI) activity %
Interface, the application is aware of activity

used to dynamically calculate short-
term activity level goals. Close

points are stored as a fingerprint location POI management
associated to each POI (GPS position statistics
is also used if available), being later etc.
