RippleDesk Using Ripples to Represent Conversational Noise on Internet Shigaku Iwabuchi Takaomi Hisamatsu Shin Takahashi Buntarou Shizuki Kazuo Misue Jiro Tanaka Department of Comupter Science, University of Tsukuba Conventional communication tools force the users to log into the system explicitly to knowing if other people have a conversation. In contrast, ripple sound in real world provides information of surrounding environment continuously and sometime creates an opportunity to make the listener to join to the conversation. In this paper we propose using ripple wave on the desktop screen to make people aware surrounding chat and aim to support their communication. We developed RippleDesk, an internet communication tool which uses ripple wave to notify the outbreak of other s conversation. As a result of the experiment, it is confirmed that ripples make the user aware of the start of a session of conversations. 1 RippleDesk RippleDesk
