Presenting EveWorks, a framework for daily life event detection

In this paper we present EveWorks, a new framework for the development of context-aware mobile applications, focused on the detection of events on people's daily lives. In our framework, events of interest are expressed through statements written in a simple domain-specific language that, being interpreted, allows for changing an application's reactive behavior at runtime. Instead of being focused on programming through technology of framework-specific components, our approach allows developers to express events in terms of more natural constructs -- intervals of time where some data invariants are true, articulated through the operators of James Allen's Interval Algebra.
