Introduction Context is a unique and powerful concept in Human Computer Interaction (HCI)
Amplify human activities with new applications and
services.
Explicit acts of communication while the context
awareness behaves implicitly.
Context is the gateway to the universe of development of services creation in ubiquitous system.

Context Operational Definitions
““Context is any information that can be used to characterize the Context is any information that can be used to characterize the situationsituation of an entity. An entity is a of an entity. An entity is a personperson, , placeplace, or , or objectobject that that is considered relevant to the interaction between a user and an is considered relevant to the interaction between a user and an application, including the user and applications themselves.application, including the user and applications themselves.””
““Context is not simply the state of a predefined environment with Context is not simply the state of a predefined environment with a fixed set of interaction resources. It’s part of a process of a fixed set of interaction resources.

Conclusion & Future Works The importance of context operational definitions and personal
assistant agents as an enabling technology for the personalisation of ubiquitous services.
A multi-agent system framework was presented to use on the enabling technologies for simultaneously observing, sensing and monitoring the user behaviour, experience and surrounding environment, and learning from user behaviour.
Helps the developer to have a clear view during the development of the personalisation service under the ubiquitous context awareness environment.
Future Works
We are planning to continue developing CAPMAS’s ability to processing semantic digital information, making a ubiquitous services system cope with user’s behaviours.
A personality agent theory and design documentation with sequencing protocols which are based on unified modelling language (UML).
