Abstract
Some chat tools are keeping the technical progress about the expression. However, the conversation using the chat tools aren't smooth. A network conversation seems to be mutter by the problem that an atmosphere and an expression aren't conveyed. In other words, the expression which supports a smooth conversation isn't realized yet. In this research, the tool which complements a network conversation with the images were created tentatively, and this tool was used for the chatting experiment. Then the logs gotten by the chatting experiment were compared about the chat using this tool with the chat of only characters.
