Abstract: Our framework can be classified in six main groups. Sensor manager retrieves and updates a program component that collects sensor data from the library. Data generator generates current or statistic summary data, or statistic index. Context generator is for developing a program to generate automatically various data and context from existing program skeletons. Class library and API is for developing a service application program or a program to extract and infer various data and context. Service generator generates a program component for summary reports, inference chain reports, communication services and personalised services. Inference engine infers context by rule-based and case-based reasoning. The developed application by our framework is extracted and infers various context such as 'moving' or 'stay home' and offers users the personalised services about current user's context.
Keywords: framework for context aware application; context awareness; personalised service; context aware system on smart phone; intelligent agent; smartphone sensor.
