VI. CONCLUSION AND FUTURE WORK
As smart phones have been shipped with more computing
power in recent years, implementation of augmented reality
on smart phones have become practical and received
attention from the public. However, the restricted size of
mobile devices and simple policy of item display on screen
have caused the items overlap. The possibility of user
mobility have not been considered either.
In order to address these issues, this paper proposed an
augmented reality service model using street data for mobile
environment. The proposed service model consists of the
real-world layer and the information layer, in which user
location and regional data elements are placed along their
pertinent streets. Queries are generated when the user views
the vicinity in the real-world layer with the camera. In the
information layer, traveling paths are considered in selecting
the regional data elements for easy access. In the proposed
model, when queries are generated for a specific street, only
the regional data elements that the user can readily access
from the user’s position are searched for, and the query
results are presented along the street.
The proposed model has been implemented for “Aenigol”,
a town where many popular Korean restaurants are open,
and we demonstrated that the proposed model adequately
addresses the issues we raised.
Augmented reality service for mobile environment
searches for information only in the user’s vicinity, so it has
been inconvenient for the user to view the data outside the
vicinity.
In the future work, we will further develop the service
model so that the user would not need to physically move in
order to view data far off the current location.
