Ototonari is a pervasive game using ad-hoc network that allows users to generate sounds based on the proximity of the users using a handheld device within a certain area. The users can not only create sounds based on their proximity with each other in the real world, but also store the generated sounds in the real space like “rumor”, so that they can share them with other users in the following game. Ototonari proved that listening to the generated sounds in the previous game influenced the present users’ action. This is the first pervasive game in Japan developed for Expo Aichi 2005 IT Experiments and is the unprecedented approach to store and inherit the data in the real world.
