The design and implementation of mobile navigation system for the digital libraries

A mobile navigation system is designed and implemented in this paper. This system can be applied to the digital libraries to make a real time query, in the library. The information provided for this system includes data and voice. The major functions of this system include information access and destination guidance. Other value-added functions can also be finished easily. There are three major parts in this system. Mobile navigation device is designed for the visitors of the libraries. In this device, wireless equipments such as bluetooth technology and IrDA device are employed to finish the major function. Man-machine interface is designed to receive the information from the mobile navigation device. Besides, man-machine interface also process the function of destination guidance. As for the information access, interface PC will pass data to the host computer to get the queried data and then pass the information to the mobile device via wireless module. The third part of the system is host computer with SQL database. The prototype of this system had been almost finished. Now, The test work is in progress. Evidences display that there is a nice effect.
