Abstract:
1. An information collecting system comprising: at least one terminal including an information input device, an information display unit and a communication circuit; and an information processing center that is connected to said terminal via a network, and includes an application server, said application server including: wherein said terminal includes a circuit for detecting power-on of the terminal, and for automatically activating said communication circuit to transmit power-on information to said information processing center, wherein said information processing center further comprises a database server, a file server and a WWW server, wherein said information processing section in said application server carries out information processing by exchanging information with these servers, wherein said receiving section of said application server receives the power-on information sent from said terminal via the network, said information processing section of said application server generates an initial picture for the terminal in response to the information received, and said transmitting section in said application server transmits the initial picture to the terminal, wherein said initial picture including a display portion for receiving user input of identification information to be transmitted to said information processing section, and, in response to receiving said user input of identification information, said information processing section to send to the terminal a subsequent picture including a plurality of menu items for user selection, including a menu item for a picture displayed on the terminal immediately before previous power-off of the terminal, and said information processing section to send to the terminal, for display, information associated with at least one of the plurality of menu items in response to said user selection, wherein said information processing section of said application server further comprises: a client application memory for storing in advance necessary information including identifying information of a user; and a client display screen constructor for constructing a client display picture from the necessary information read out of said client application memory and information supplied from other servers, wherein said application server further comprises: a client display picture storage for storing the client display picture generated by said client display screen constructor; and a differential detector for detecting a difference between the client display picture stored in said client display picture storage and a client display picture newly generated by said client display screen constructor, and wherein said transmitting section transmits only differential information detected by said differential detector to said terminal.
