In-Depth Information
3.1 Sensor, Activity and Participant Profiles
These three profiles are similar in nature. The sensor Profile allows for different
sensors to be introducted at any point, providing their output is described using
a template. The Activity Profile defines the activity or domain in which a set
of sensors were deployed. Some of this information is standard for each activity,
such as the start time, the sport involved and the list of sensors deployed. In
addition, the Activity Profile defines the key elements of a deployment that
are relevant for that sport and particular deployment. The Participant Profile
provides the anthropometric data valid for a user at the time of deployment.
There can be many participants, each with their own profile, in an activity.
3.2 Event Definition
The key componant of contextual enrichment are the Event Definitions. These
enable the end user to highlight important events during exercise activity given
the domain algorithms required for a certain set of sensor data. These algorithms
are defined by the end users. The Event Definition uses the traditional event-
condition-action format with a sample event is shown in Example 1. The key
elements are the
Event
, which has
Condition
and
Action
sub-elements. There
may be multiple
Condition
elements joined by logical operators and any number
of update
Action
elements.
