Sometimes it can be useful to use a graphical interface with a Furhat skill. For example, you could have a game interface on a touch display and have Furhat play the game with you. Or, you might want to display information on the display in addition to Furhat's verbal instructions.
This is possible through the Displays concept, where you essentially access the web interface from another device and select become a display. In order for Furhat to know where the Display is, so that he can attend it, you can set it's position in this step.
