  • Publication number: 20150286365
    Abstract: An image distribution device receives, from a terminal device, a handwritten and input image including a trajectory handwritten and inputted by a first user in a state where a virtual space, in which characters of the first and a second user are present, is set as a background, to a display view of the terminal device on which the virtual space is displayed. By transmitting, to the terminal device, the received handwritten and input image as a message from the first user, the image distribution device displays the handwritten and input image on the display view of the terminal device on which the virtual space is displayed while associating the handwritten and input image with the character of the first user.
