A notification control device includes: a sound notification controller sending a first notification control signal for causing a first device to provide a first notification, obtaining first response information to the first notification, and determining whether the first response information is in response to notification information; an image notification controller sending a second notification control signal for causing a second device to provide a second notification, obtaining second response information to the second notification, and determining whether the second response information is in response to the notification information; and a canceller sending a cancellation process signal for cancelling (a) the second notification when the sound notification controller determines that the first response information is in response to the notification information and (b) the first notification when the image notification controller determines that the second response information is in response to the notification information.
