Abstract

A context aware enterprise system includes a network, an enterprise service coupled to the network, and a plurality of information sources that include enterprise information related to one or more activities of the enterprise system. The enterprise system also includes a plurality of clients with user interfaces by which a user may access the enterprise service over the network. A context determination service determines context information describing a multi-dimensional context based on the enterprise information. The context information determined by the context determination service includes a user identification, an identification of a client selected by the user, a user role, a user expertise related to the enterprise service, and a user expertise related to the selected client. Based on the context information, an interface adaptation service adapts the user interface of the client.

23. The system of claim 1 wherein the plurality of information sources does not include an information source configured only to provide context information.

24. The system of claim 23 wherein the plurality of information sources does not include a GPS configured to provide a location of a client device.

25. A method of adapting a user interface of a client in an enterprise system based on multi-dimensional context information, the method comprising:

receiving a request of a user to login to an enterprise service of the enterprise system using a client;

determining first information based on the request to login to the enterprise service using the client;

determining second information from a plurality of information sources of the enterprise system based on the first information;

determining context information describing a multi-dimensional context based on the first information and the second information, wherein the context information comprises a user identification, a client identification, a user role, a user expertise related to the enterprise service, and a user expertise related to the client; and

adapting the user interface of the client based on the context information.

26. The method of claim 25, wherein adapting the user interface of the client based on the context information comprises selecting a sensory communication path for the interaction of the user with the enterprise service that is suited to a context described by the context information.

27. The method of claim 26 wherein the sensory communication path selected comprises a voice communication path.
