In the living room too, and in all other rooms, we need to consider what the intentions of the residents might be when entering and leaving the room, or when using the room. In the living room, it might be: watching TV, receiving guests, playing with the children, reading a good book, spending a romantic evening with a partner, etc. In such a case, we are inclined to provide a switch for every intention. Should the resident wish to operate the lights, roll-down shutters, etc., individually, we propose to do this via a remote control. In an effort to increase user-friendliness, in certain circumstances we can provide icons on the buttons. These indicate the function of a button.
Icons that indicate the function of a button increase user-friendliness. (Illustration source: Niko)
