Modeling the Environment and the Software

This paper presents a feature model for a mobile calendar application that emphasizes environment-aware capabilities. It outlines a layered approach to context acquisition, allowing the app to dynamically adapt based on environmental conditions such as network connectivity (WiFi, 3G). Key features include event location sharing, integration with social networks, email, and SMS, as well as cloud and local storage solutions. The model enables real-time feature selection and removal, ensuring optimal functionality in varying contexts and enhancing user experience through intelligent context awareness.
