DOOR BELL
An interactive door bell.
The visitor has a real impact on the way he wants to call people inside the house.

By speaking in the tube outside the door, people switch on the little bell-plugs disseminated in the house. The louder they speak, the louder the inhabitants will here it.
Inhabitants modulate the door bell by plugging the bells wherever they need them: in the kitchen while cooking, in the room while reading or even by their neigbours when they are visiting them.
Technology here brings a more humanized way of ringing the doorbell.
