With rapid developments in the combined technologies of tourism and mobile communications, Internet access is readily available, anytime and anywhere. The mobile data service industry has gradually replaced voice services, and become the target market of mobile telecommunication system operators. In the mobile commerce field, the characteristics of Location Based Services (LBS) vary widely according to the users' current environment, service demands, and variations in positions. Therefore, how to know the current position of a user and respond to requests to provide different services is an important challenge of the future. This study proposes corresponding solutions to overcome the above problems. Using the tour guide map as an example, to complete a "mobile tourist guide map information service", a user can employ the camera function of a mobile phone to sense and capture a mobile barcode, and then connect it to the backend database of the server, through a wireless network for e-map information and voice guides, and make on-line inquiries regarding e-maps. The most convenient route of nearby communications can be obtained through the tourist guide map, allowing users an audio guide service to find their way.
