Abstract: A control system includes a timing device to indicate an elapsed time from a time point at inversion of the timing device, and a computer including a transmitter to start transmission of a control signal according to a control scenario determined with a predetermined signal to a predetermined device other than the timing device if switching of the timing device to an operational mode is determined, and to transmit a signal indicating the end of the control for the predetermined device if switching of the timing device to a nonoperational mode is determined. The control system reduces the number of steps of managing tokens, archives, and token passwords by a terminal manager, and further improves the security level of the terminal.

Abstract: A choreography-creation aid method includes: receiving, from a terminal that is present in a certain area, information that enables identifying a location of the terminal; determining, for each of sections obtained by dividing the certain area into two or more, whether a number of terminals that is calculated from the received information that enables identifying the location is greater than a certain number, by a processor; and transmitting, to at least a part of terminals out of the terminals present in a first section for which the number of terminals is determined to be greater than the certain number, a request for moving to a second section for which the number of terminals is not determined to be greater than the certain number.
