ON-OFFLINE INTEGRATED RESEARCH METHOD USING PDA

摘要

PURPOSE: An on-offline integrated research method using a PDA(Personal Digital Assistant) is provided to realize correctness through an offline research interview between a taxi driver and a passenger by using the wireless Internet based PDA. CONSTITUTION: If a taxi is started, the PDA of the taxi is automatically connected to an integrated management server(S100). The server transmits questionnaire to the PDA by operating a database of the server(S110). The PDA receiving the questionnaire stores the received information in the database of the PDA(S120). The server transmits a screen to input the personal information of a passenger and a PDA number, and receives the inputted information. The server stores the information from the PDA in a member database and transmits a member number to the PDA through an SMS(Short Message Service). If the member number inputted from the passenger is agreed with the stored number, the questionnaire corresponding to the personal information of the passenger is displayed on the PDA(S190). The PDA transmits the data selected by the passenger to the server.
