A notification control device includes: a sound notification controller that sends a first notification control signal for causing a first device to provide a first notification, obtains first response information to the first notification, and determines whether the first response information is in response to notification information; an image notification controller that sends a second notification control signal for causing a second device to provide a second notification, when the first response information is determined not to be in response to the notification information, obtains second response information to the second notification, and determines whether the second response information is in response to the notification information; and a canceller that sends, to the first and second devices, a cancellation process signal for cancelling the notifications, when the first response information or the second response information is determined to be in response to the notification information.
