Abstract
A handheld virtual overlay system (HVOS) device is presented that includes a global positioning system (GPS) receiver for detecting a global position of the HVOS device; a compass/tilt sensor for detecting a direction and tilt of the HVOS device; a communication module for transmitting the global position, the direction, and the tilt to a data store; and an input/output display configured to receive and display a rendered image. The data store is configured to receive the global position, the direction, and the tilt, and to generate geo-coded data for transmission to a server, where the server is configured to receive the geo-coded data and to transform and render the geo-coded data into a rendered image. A user can point the HVOS device at a scene, with the HVOS device producing a rendered image representing the scene.
