Human-machine dialog system

A human-machine dialog system comprising:

• a first part including a data processing unit and an electrical power supply unit;
• a second part including a plurality of human-machine dialog members each provided with a human-machine dialog interface, and a fastening support arranged to accommodate each human-machine dialog member in a removable and interchangeable manner;
• and
• a communication and power supply bus linking the power supply unit and the processing unit of the first part to each human-machine dialog member, said communication and power supply bus including two conductive lines extending through one orifice in a wall to two parallel conductive rails arranged in the fastening support to connect each human-machine dialog member, the plurality of human-machine dialog members being arranged in an adjacent fashion one after the other by sliding on the two parallel conductive rails such that the plurality of human-machine dialog members are located between the two parallel conductive rails, wherein
• the first part is positioned on a first side of the wall and the second part is positioned on a second side of the wall, the first part and the second part being connected to each other via the two conductive lines, the two conductive lines both extending through the one orifice in the wall, which separates the first part and the second part, to the two parallel conductive rails that are arranged in the fastening support included in the second part, and
• the wall includes the one orifice, through which both of the two conductive lines extend, a second orifice located at a first end of the wall and configured to receive a first fastening member, and a third orifice located at a second end of the wall and configured to receive a second fastening member.
