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. 11.08.2004 4

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. 11.08.2004 5
