The shape of “Do not disturb” comes from the study of the use of handles to use them not only as a closure or opening mechanism of the door, but also to be able to provide information on the status of the room that it closes or opens. Besides its standard use of opening and closing of the door, the handle can assume two positions, one neutral, which reveals no information about the state of the room and a second position (the most unique) allows the user to communicate a brief message.
