Subject: Since today's conventional Web browsing employs Pull-Type Telecommunications, presently, it is necessary to employ keyboard operation in order to request information. Furthermore, the portability of today's devices is still substandard, and offering information based on another's situation is presently unavailable.Method for Solution: When each telephone caller uses a telephone (including a cellular telephone), the computer connects the public Internet network and the Telecommunications with the exclusive software carried at each device, and the server performs Push-Type Telecommunications on the network, with which any information that is selected and transmitted by one side at any time is displayed or played automatically on the other side's monitor during conversation, the method by which audiovisual information is offered during the course of conversation is realized. Thus, as a result, a wide variety of functions, including an operation support function, a presentation function, conversation support using visual information, a performance offering a theme, as well as the advantage of enhanced portability, are all realized, and various services, including personalized, are enabled by automatically displaying the processed result of sound (voice) as input data on each telephone caller's monitor.
