Apparatus and method of ubiquitous context-aware agent based on sensor networks
First Claim
1. An apparatus of an ubiquitous context-aware agent based on a sensor network, the apparatus comprising:
- a sensor platform for collecting data of real world and transmitting the collected data to a context-aware agent;
the context-aware agent for interpreting and integrating the data of real world from the sensor platform, and storing and managing context information according to the interpreted and integrated data; and
a service provider for receiving the context information from the context-aware agent, and automatically performing operations according to the received context information, wherein the context-aware agent includes a context interpreter for receiving the collected data from the sensor platform and interpreting the received data to be viewable to a human and a computer;
an integrator for receiving an interpreted context information from the context interpreter and integrating the received context information in a predetermined format;
a space manager for receiving the interpreted context information from the context interpreter and detecting users'"'"' intention with reference to a relation between a users'"'"' movement and static objects in a predetermined space;
a home map manager for receiving the interpreted context information from the context interpreter, and displaying current states of a real world to the user using the interpreted context information;
a context storage for storing information transferred from the context integrator, the space manager and the home map manager, and outputting the stored information in response to a request; and
a context manager for receiving the predetermined format of the integrated context information from the context integrator and managing the context information stored in the context storage.

Abstract
An apparatus and method for context awareness by detecting intentions of a user in the ubiquitous environment using context information which is created by analyzing real world data collected from sensors are provided. The apparatus is configured of a sensor platform, a context-aware agent and a service provider. The sensor platform collects data of real world and transmits the collected data to the context-aware agent. The context-aware agent integrates the data of real world from the sensor platform, and stores and manages context information according to the integrated data. The service provider automatically controls objects to perform necessary operations to provide a predetermined intelligent services according to the context information received from the context-aware agent.

7. A method of context-awareness using an ubiquitous context-aware agent based on a sensor network comprising:
-
detecting sensing-data related to a real world collected through a sensor platform, and transforming the sensing-data to context information by analyzing a meaning of the sensing-data; determining whether a value of the transformed context information is in a normal range or not if a type of the transformed context information is an environmental context; setting an urgent flag, storing corresponding context information and transferring the context information to a service provider if the value of the transformed context information is not in the normal range; integrating context information, storing corresponding context information, filtering the stored context information and transmitting the filtered context information to the service provider if the value of the transformed context information is in the normal range; analyzing a relation between a moving object and a static object if the type of the transformed context information is a position context, detecting an intentions of a user according to a position, and determining whether it'"'"'s value is in a normal range or not; and integrating context information, storing corresponding context information, filtering the stored context information and providing the filtered context information to the service provider if the value is in the normal range. - View Dependent Claims (8, 9, 10, 11)

12. A method of inferring a position context in a context-aware method using an ubiquitous context-aware agent based on a sensor network, the method comprising:
-
determining a type of an object through monitoring context information in real time, and creating an object model and an object area model if the type of the object is a static object; detecting a qualitative state if the type of the object is a moving object in the operation of the determining and creating or if the object model and the object area model are created in the operation of the determining and creating; generating a qualitative state message based on the detected qualitative state and storing the generated qualitative state message; generating an object relation message by inferring an object relation using the qualitative state message and storing the generated object relation message; and generating a semantic model using a stored object relation model, generating a semantic model message according to the generated semantic model and storing the semantic model message. - View Dependent Claims (13, 14, 15, 16, 17)
