In-Depth Information
The major uncertainty of this research is about accuracy of the GPS. In
the experimental results, there are errors from [4] meters to 104 meters; the
average is about 12 meters. Obviously the level of errors is too large to be
accepted. It really affects the process of such survival games. The solution
in this chapter is using better GPS component with antennas. The average of
improved errors is about 4.4 meter. The results are much better than the orig-
inal ones. In the proposed learning platform in this dissertation, accuracy is
not very important as in mobile games. If a higher accuracy is necessary, a
higher class of GPS component can be installed in our system.
Some researches focus on providing services to users by GPS compo-
nents and electronic map. A project of websigns was published by Pradhan,
Brignone, Cui, McReynolds, and Smith [12]. The websigns are a kind of
hyperlink to physical locations. Users can access relative information of these
physical locations by websigns. The kernel components of websigns are vir-
tual beacons and virtual tags. The beacons are based on IR beacons and the
tags are based on RFID tags. With these websigns, users can download and
browse information from the network. They just need to scan IR beacons or
Radio Frequency Identification (RFID) tags, then they can access information
on their mobile devices.
Another application of electronics maps was published by Naaman [11].
Yahoo map is a free service to let users examine maps on the network. By
integrating with Flickr's services, users can add photos on a Yahoo map.
There are also customized profiles so users can edit their own maps with
photos.
13.7 Conclusion and Future
An intelligent travel topic management system integrated with the agent
and Web technologies is introduced in this chapter. In order to save visitors'
time and improve efficiency of creating travel notes, the wizard on the client
side, an agent, and a management server are implemented. The wizard runs
on the users' mobile devices, collects and filters information from visitors'
photos and comments. Geographical information gathered from the GPS
component in the mobile devices also provides a means to get precise land-
marks on a visitor's journey. The string of landmarks generated by a selection
engine will input to an agent, and these related materials on the Internet will
be collected for references in the phase of travel notes editing. All resources
from users and agents can be accessed by the travel topics manager in the
server. Visitors can easily create blogs and include the multimedia resources
collected on their journey. Other reference web pages and images are also
available in the resource pool. By this management system, creating travel
notes becomes an easy task and even an entertainment for users.
