Interactive 3D menu

I’m trying to create an interactive 3D menu, supporting camera movements and touch input, similar to this menu:

I’m able to move the camera around based on the swipe direction, but i’m not sure how to detect touches to activate new menus or even how to separate screens. Should i make all objects respond to touch independently from which “screen” they are? Also, how can i smooth the camera movement like in that video?

Bumping. :smiley:
