V. SYSTEM CONFIGURATION
The AR service proposed in this paper requires the
following for implementation: camera, GPS, azimuth
sensor, and street data extracted from a numeric map. Fig.
17 shows a sample setup. When the user runs the service,
the mobile device transmits the user’s location data obtained
from GPS to the server. Based on the user’s location data,
regional data elements and the street data that fall in the
vicinity are searched for in the database, the result of which
is sent to the device.
