Augmented Reality Gps
Augmented Reality, especially out-door and public uses of augmented reality, take advantage of Geo Positioning Satellites (GPS). GPS allows one to locate ones location and altitude to within a meter of accuracy (Maps-gps-info.com, 2011). GPS receivers are installed in almost all current smart phones, tablets, and PDA’s (Personal Data Assistants). GPS can also be easily added to any kind of computer controlled equipment.
Augmented reality leverages the availability and accuracy of GPS to “digitize” the user’s location, altitude, and direction of travel. This in turn allows the augmented reality application to easily overlay the digital data with the user’s location data and view of the world. Thus, when a user looks at a street through the application, the software knows where in the world the user is, and in what direction they are looking.
