An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves.” “A system is context-aware if it uses context to provide relevant information and/or services to the user, where relevancy depends on the user’s task.” 25 ίϯςΩετΞ΢ΣΞωε Gregory D Abowd, Anind K Dey, Peter J Brown, Nigel Davies, Mark Smith, and Pete Steggles.
