GPS

GPS
GPS is an acronym for Global Positioning Satellite. Devices with GPS built-in are aware of their location on the surface of the earth. This information can be useful in augmented reality systems because it allows the AR system to know what the “real” reality of the device is, pull in correlating data (like nearby map features, weather, other GPS data encoded objects and so on). In conjunction with a compass, GPS can have a sense of what direction the device is facing–perhaps enough to place useful data or artwork into a live video overlay.
