1. A system for displaying and updating data in three dimensions, comprising: a computer system connected to a communications network and configured to process data regarding multiple locations and create a virtual three dimensional orthogonal space wherein the data is associated with a multiple locations in the virtual three dimensional orthogonal space; a wearable display device connected to the computer system; a head-tracking sensing sensor system connected to the wearable display device and to the computer system, configured to sense the movement and orientation of the wearable display device in real-time; an eye-tracking sensor system connected to the wearable display device and to the computer system, configured to sense the eye movement of a user wearing the wearable display device in real-time; wherein the computer system is configured to receive real-time data from the head-tracking sensing system and the eye-tracking sensor system and to process said real-time data to generate an image of the virtual three dimensional orthogonal space for display on the wearable display device; and a handheld control device that is configured to send a signal to the computer system, wherein the computer system is capable of displaying data related to any of the multiple locations.
