COMMUNICATION SYSTEM, COMMUNICATION DEVICE, AND COMMUNICATION METHOD

摘要

A mobile device (1) is provided with a communication unit (11) which performs communication via wireless communication, a display unit (12), and a display control unit (131) which controls the display unit (12) to display a setting input screen for allowing the user to input setting of a household electrical device (3). The communication unit (11) transmits a request signal for checking whether there is a person in the vicinity of the household electrical device (3) before the setting input screen is displayed by the display control unit (131). The display control unit (131) controls the display unit (12) to display a setting input disable screen indicating that setting of the household electrical device (3) is not received without causing the display unit (12) to display the setting input screen when there is a person in the vicinity of the household electrical device (3).
