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.

Communication system, communication device, and communication method

A communication apparatus includes: an area dividing unit that divides, of an output image which is an image that the communication apparatus has output and includes at least a shot image obtained by shooting the surroundings of another communication apparatus which communicates with the communication apparatus, a display area indicating an area where the shot image is displayed into as many unit areas as the number of people captured in the shot image; a transmission control unit that controls transmitting coordinate information which indicates, of the output image, a unit area corresponding to a position pointed by a user to the other communication apparatus; and an output control unit that, when the communication apparatus has received output information including a voice subjected to directivity control according to, of the shot image, an area corresponding to the coordinate information from the other communication apparatus, controls outputting the received output information.
