1. A system for guidance and navigation in a building, comprising:
- a module for obtaining locations of one or more people in the building;
a module for selecting a route based on the locations in a building;
a module for processing the route into waypoints and segments;
a module for associating semantic information with waypoints;
a module for processing the waypoints and segments into navigation commands formed from a sentence template; and
a module for providing and associating audio tones with waypoints; and
wherein;
the system comprising the modules is implemented on non-transitory computer readable media; and
the audio tones are for distinguishing waypoints from one another and pulse rates for indicating various distances of the recipient of the audio from a waypoint.

Abstract
A system for guidance and navigation in a building. For example, the system may determine a route for egress or rescue of one or more people from a building with a hazardous condition. The system may process the route into waypoints and segments developed within a set of constraint rules. Semantic information about the building may be associated with the waypoints and/or segments. The waypoints and segments may be processed into navigation commands. The navigation commands may be formed in natural language from sentence templates. The system may additionally have 3D beacon audio to assist in guidance and navigation of the one or more people in the building.

9. A method for providing guidance and navigation inside a building, comprising:
-
obtaining structural information for the building with a floor plan generator and obtaining condition information about the building with hazard detectors; selecting a route for a person inside of the building with a route generator; processing the route into waypoints and segments with the route generator; associating semantic information with the waypoints with the route generator; providing navigation commands formed in natural language with a sentence template to the person for proceeding along the route via the waypoints and segments; and providing and associating audio tones with waypoints; and wherein the audio tones are for distinguishing waypoints from one another and pulse rates for indicating various distances of the recipient of the audio from a waypoint. - View Dependent Claims (10, 11, 12, 13)

14. A system for guidance and navigation in a building, comprising:
-
a floor plan generator; a sensor for indicating a location of with a person in the building; a route generator connected to the floor plan generator and location sensor for generating a route for the person; and a sound generator for providing and associating audio tones with waypoints; and wherein; the route is in a form of segments and waypoints demarking the segments; the audio tones are for distinguishing waypoints from one another and pulse rates for indicating various distances of the recipient of the audio from a waypoint; a waypoint is associated with a location; a sequence of waypoints indicates the route; natural language navigation commands are generated from the segments and waypoints; natural language navigation commands are formed from sentence templates; and semantic information is attached to one or more waypoints and/or segments. - View Dependent Claims (15, 16)
