Interactive system, interaction control method, and interaction control program

An interactive system comprising:

• a communication device which performs communication with at least one terminal;
• a storage device which stores identification information for identifying interaction processing with the terminal;
• and
• an interaction control device which performs control so that, when the new interaction processing with the terminal is started, the interaction control device transmits the identification information for identifying the interaction processing to each terminals while storing the identification information in the storage device, when the interaction processing is in progress, the interaction control device stores progress information for indicating a degree of progress of the interaction processing in the storage devices while the progress information is corresponded to the identification information, and, when the interaction control device receives the same identification information as the identification information of the interrupted interaction processing from the terminal or another terminal different from the terminal after the interaction processing with the terminal is interrupted, the interaction control device causes the terminal to participate in the interaction processing from the degree of progress in which the interruption has occurred.

An interaction control method which is executed by a computer system including a communication device performing communication with a terminal and a storage device, comprising steps of:

• transmitting identification information for identifying the interaction processing to the terminal while storing the identification information in the storage device, when the new interaction processing with the terminal is started;
• executing a series of interaction processings in response to information received from the terminal;
• storing the identification information in the storage device while progress information for indicating a degree of progress is corresponded to the identification information, when the interaction processing is in progress;
• and
• permitting the terminal or another terminal different from the terminal to participate in the interaction processing from the degree of progress in which interruption has occurred, when the same identification information as the identification information of the interrupted interaction processing is received from the terminal or another terminal different from the terminal after the interaction processing is interrupted.

An interaction control program which can be executed by a computer system including a communication device performing communication with at least one terminal and a storage device, the interactive control program causing the computer system to sequentially execute steps of:

• transmitting identification information for identifying interaction processing to the terminal while storing the identification information in the storage device, when the new interaction processing with the terminal is started;
• executing a series of interaction processings in response to information received from the terminal;
• storing the identification information in the storage device while progress information for indicating a degree of progress is corresponded to the identification information, when the interaction processing is in progress;
• and
• permitting the terminal or another terminal different from the terminal to participate in the interaction processing from the degree of progress in which interruption has occurred, when the same identification information as the identification information of the interrupted interaction processing is received from the terminal or another terminal different from the terminal after the interaction processing is interrupted.

An interactive system comprising:

• a communication device which performs communication with a terminal;
• a interaction control device which responds to information received from the terminal to execute a series of interaction processings;
• and
• a storage device,
• wherein the interaction control device stores identification information for identifying the interaction processing when the new interaction processing is started, and the interaction control device can cause the terminal to participate in the interaction processing concerned with the identification information in the case where the interaction control device receives the same identification information as the identification information of the ongoing interaction processing from the same terminal or another terminal when the interaction processing is in progress.
