In a setting of three objects and three assistants (text-aid for understanding the gestures) and only one space to display the text, I need a layout which makes clear which object is «currently» speaking.
The first image above depicts such a layout. The question is, if the subtle color differences and the label («Radio», «Lamp», «Ventilator») is enough to distinguish the different assistants. And what if one would like to read the comment of the lamp, which may already left the screen because of two quick messages of the radio?
Maybe the second picture makes it more clear, which object is currently active.
In a setup where object selection has to take place (with only one leap motion) (see Prototyping Object Selection) it would also be imaginable that only the chat of the currently active object is displayed.
An animation between the different object chats would be necessary and could maybe look like this:
