In a world in which several small computing devices communicate with each other and with humans in a context-aware manner, short-range, localized communication is critical. Efforts such as IrDA and Bluetooth show that simply scaling down the existing communication network does not properly address short-range communication. The authors argue that sound will play an important role in this new computing world. Sound offers features not available with other short-range, low bandwidth communication technologies, such as radio and infrared. For example, sound can be constrained within a room, eliminating outside interference. Sound can also expose the communication to humans when necessary. The authors describe several aerial acoustic modems that account for various human factors, such as the appeal and familiarity of message sounds.
