A multiple-display device comprises a front and a rear display. The front display includes a front image area facing a front direction. The rear display is mounted opposite the front display and includes a rear image area facing a rear direction, opposite the front direction. A display controller is provided for controlling the front and rear image areas to render images thereon, including a transfer port image on the front image area. A touch-sensitive panel is mounted on the front display in registration with the front image area. A panel controller is operable to detect a rendered element on the front image area being dragged by a user to the transfer port image and in response thereto to inform the display controller, so that the display controller can instantiate the rendered element on the rear image area.
