ListenIn uses audio to link two environments; it is motivated by the desire by caregivers to monitor domestic environments with elderly or infant occupants. Wireless microphones in the home collect sound, classify it, and then transmits either iconic representations of the sound, a few seconds of the sound itself, or, if the sound contains speech, a "garbled" version of the sound. The remote client plays these snippets of sound as background audio, allowing one to listen in while away from home as an occasional, ambient auditory experience.
