What is holographic, and what isn’t?

[Philip Lelyveld comment: this is a nice academic discussion that argues we should define holographic by the experience, not the technology.]

When viewing close-by objects, there are six major depth cues that help us perceive three dimensions:

1. Perspective foreshortening: farther away objects appear smaller
2. Occlusion: nearer objects hide farther objects
3. Binocular parallax / stereopsis: left and right eyes see different views of the same objects
4. Monocular (motion) parallax: objects shift depending on how far away they are when head is moved
5. Convergence: eyes cross when focusing on close objects
6. Accommodation: eyes’ lenses change focus depending on objects’ distances
