Background Art
In general, a Personal Digital Assistant (PDA) is a personal communication device in which the functions of collection, storage, processing and exchange of information are combined. The use of PDAs has increased. In more detail, the PDA can be called a portable communication terminal. The PDA is smaller than a notebook computer, but more powerful than an electronic organizer. The PDA basically provides a personal information management program for schedule management, an address directory, a memo pad, etc., can freely exchange data with personal computers, and is equipped with additional application programs aside from basically installed programs.
Currently, PDAs exploit new application fields including wireless Internet application. For example, PDAs can be basically utilized to manage personal information using basically provided programs an additionally installed application programs. Meanwhile, personal computers are equipped with personal information management programs corresponding to the personal information management programs of PDAs. Accordingly, a new personal information management method, in which the personal information can be amended, supplemented and backed up while the PDA connects with the personal computer, is proposed. Additionally, for wireless Internet, there can be implemented the principal functions of the Internet application that can be performed by personal computers, such as Web-page search, e-mail, personal computer communication, stock trading, etc. Additionally, for other applications, PDAs are applied to various fields such as management automation (the collection and exchange of data, the monitoring of work, the assignment of work, the input of orders, the transmission of bills, access to customer database, etc.), conveniences and public safety management (the report of accidents, the control of parking, emergency service and repair, the inspection of meters, maintenance and repair, and audit), transportation and inventory management (the inspection of inventory, the arrangement of work and process, etc.), financial business (the management of the agents of insurance and mutual funds), etc.
Currently, the research and development of PDAs equipped with a variety of functions are carried out. However, the development of PDAs equipped with practical functions except for functions closely related to the original function of the PDAs is not sufficient.
