US Patent 9811249 Generating an operational user interface for a building management system

Devices, methods, and systems for generating an operational user interface for a building management system are described herein. One method includes generating a widget using geometrical information associated with a building information modeling object and relationship information associated with the building information modeling object, assigning a state variable to the widget by analyzing properties of the building information modeling object or an ontology definition of the building information modeling object, associating the state variable with a point from the building operation system by mapping the point to the state variable, and changing the state variable based on input received from a user.
