Ambient-awareness?

  • Ambient information describes the environment of the user at

a certain moment in time. This includes physical measurable data, but also relevant items residing in the environment, such as devices and other objects.

  • Multi-context indicators:

– Physical contextual indicators, e.g. levels of brightness, noise, humidity, and temperature. – Computing context indicators, e.g. network connectivity characteristics, nearby devices. – User context indicators, e.g. user’s location, social conditions, user’s history. – Temporal context indicators, e.g. time of day, day of week, time before or after a specific event.

  • Ambient awareness means to consider and to adapt to

information about the user’s environment (ambient information) in the service provisioning.

Obtaining ambient info

  • Directly

– From sensor devices, which measure and provide physical values. – From explicit user statements, by which the user himself describes the environment, e.g. specifying the current location.

  • Indirectly:

– By interpreting available data in order to process/revaluate more information. For example, if the location of an active user terminal is known, the location of the user can be derived accordingly.

Context Modeling

  • Resource Description Framework (RDF) provides data model

specifications and XML-based serialization syntax

  • Web Ontology Language (OWL) enables the definition of

domain ontologies and sharing of domain vocabularies
