Abstract: A display device includes a first camera that captures an image of a first viewer present in a first normal direction of a display surface of a transparent display, a second camera that captures an image of a second viewer present in a second normal direction of the display surface of the transparent display, the second normal direction being an opposite direction of the first normal direction, a microphone, and a control circuit that includes a user coordinate calculation circuit, a gesture detection circuit, a dictation circuit, and a drawing information generation circuit. The user coordinate calculation circuit specifies positions of the first viewer and the second viewer on the basis of the images from the first camera and the second camera. When the gesture detection circuit determines that the first viewer utters sound, the dictation circuit generates a character based on sound information from the microphone, and the generated character is displayed on the transparent display toward the second viewer by the drawing information generation circuit.
