But do you differ the design of those different signs?
It would somehow feel strange to go to a sign with a print on and after you interact with it, more text appears in other display..
I'd personally keep the signs above just for the text it displays without interaction. And for longer texts there could be in example scrolls / books. If you focus on the scroll, you could blind in kind of headline next to it. And if you interact with the scroll, it opens in a second display (or however you want to visualize it). So it feels like, you take up an closed element and open it up to read in detail. With these wooden signs, as i imagine it, would be bit strange. Of course it's just my personal taste and maybe you surprise me by another throughthought logic and optic.
