Abstract
Smart phones and other mobile devices have a simple notion of context largely restricted to temporal and spatial coordinates . Service providers and enterprise administrators can deploy systems incorporating activity and relations context to enhance the user experience , but this raises considerable collaboration , trust and privacy issues between different service providers . Our work is an initial step toward enabling devices themselves to represent , acquire and use a richer notion of context that includes functional and social aspects such as co-located social organizations , nearby devices and people , typical and inferred activities , and the roles people fill in them. We describe a system that learns to recognize richer contexts using sensor data from a person's Android phone along with annotations on her calendar and general background knowledge . Classifier models predict the individual users ' context with respect to a mid-level detailed activity he is performing like `Listening a Talk ', `Walking ', `Sleeping ', etc. We report on an evaluation of the individual and generic models in the University setting for predicting context .
