A hologram area trigger works EXACTLY like a normal area trigger and links to the same area trigger controller. The difference is that a transparent, glowing icon appears in its center. That's the basics of it.
An additional feature could be the ability to change the icon. This could be done through the block's "rotation" or by adding an interface to the area trigger controller. Some icons might include: Sphere, Cube, Disc, Crosshair, Platform (symbolising an elevator), X, O, Schine Logo.
If combined with the upcoming rail system, this feature should allow replicas of elevators from Metroid Prime. "Step into the hologram to activate the elevator."
