Abstract
Attention can be effectively called to an advertisement, and the effect of calling attention can be known. A control device is connected to a super-directional speaker that outputs audio in a specific direction, and a speaker pedestal that adjusts the audio output direction of the super-directional speaker. The control device takes a picture of an area in front of an advertisement display surface by means of a camera, detects a person photographed in the image captured by the imaging unit as a target, adjusts the audio output direction of the super-directional speaker to the direction of the target by means of the speaker pedestal, and causes the super-directional speaker to output audio. After outputting the audio, the control device takes another picture by the camera, and again determines the direction in which the face of the target is looking based on this picture.
