摘要
We present Ambient Pre-Communication for always-on tele-communication systems. It allows the Caller to feel more comfortable
in initiating communication, as comfortable as in the real world. To start communication in the real world, determining the
appropriate voice volume is essential. However, existing tele-communication systems fail to support the Caller in controlling
voice volume because the systems don’t provide feedback of the Caller’s voice at the Receiver’s site. Our proposal allows
existing tele-communication systems to provide visual feedback. The key idea is to superimpose a ripple-peak-meter, which
represents the sound field at the Receiver’s site, on the Receiver’s video signal. The Caller can control his/her voice volume
using the ripple-peak-meter. We describe a prototype system and experiments in which we observed the Caller’s response to
the ripple-peak-meter display. The proposed method allows the Caller to easily grasp and control the volume of his/her voice
at the Receiver’s site and encourages him/her in commencing tele-communication.
