  • Patent number: 10596472
    Abstract: A user apparatus is provided that is connected via a network to a server apparatus, the server apparatus being connected to at least one other user apparatus via the network. The user apparatus includes a receiver that receives new messages distributed from the server apparatus via the network, and a display device that sequentially displays the new messages received from the server apparatus on a display area of a display screen. A specific old message may be selectively retained in the display area of the user apparatus instead of being updated by display area update processing. Additionally, the display area update processing sequentially displays the new messages when there is no specific old message identified with high importance, and retains the specific old message in the display area when the specific old message is identified with high importance, even when a new message is received.

  • Patent number: 9597601
    Abstract: Players input their messages in their video game apparatuses and the messages are once collected at a server apparatus, thereafter they are distributed to all video game apparatuses from the game server apparatus. In a display screen of each video game apparatus, a chat window is displayed in order to display messages exchanged between the players on a game screen including a field and characters of the game. The chat window is sequentially enlarged up to a preset maximum number of lines when a new message is received from the game server apparatus. The chat window is sequentially reduced to the preset minimum number of lines when a predetermined time passes without any reception of new message or when the player performs a specific operation.
