A device performs to: generate second correspondence information indicating a correspondence relation between coordinates of a projection area and coordinates of a captured image based on first correspondence information indicating a size of the projection area indicating an area to which an image is projected by an image projection device, a size of a basic area indicating an area predetermined as the area to which the image is projected, and indicating a correspondence relation between the coordinates of the basic area and the coordinates of the captured image obtained by an imaging unit; transmit coordinate information indicating a range, of the projection area, specified by a user and the second correspondence information to other device; and output, when receiving output information including voice whose directivity is controlled according to an area corresponding to the coordinate information of the captured image from the other device, the received output information.
