System and method for providing subject location information

摘要

A system for providing subject location information for use by one or more software applications includes an environmental model ( 14 ) storing environmental location information including environment subsections defined by system location co-ordinates. The environmental model communicates with the one or more software applications ( 12 ) for receiving an application-specific location request including an area of interest, an application-specific system coordinate resolution and an application-specific update frequency. At least one location sensor ( 20 ) senses the position of a subject within the area of interest at a sensor-specific sensing frequency to provide sensor-specific subject location information. A sensor translator ( 22 ) translates the sensor-specific subject location information to system location coordinates having the application-specific system coordinate resolution and updates the translated system location coordinates at the application-specific update frequency.
