Illusions, Michael.
Is it not fair to say perspective can be used in illusions? Or how are you defining illusion?

Is perspective really considered an “illision”? While this demonstrates perspective it at no point makes me see something that isn’t real.

Illusion is seeing something that isn’t there. They can be caused by multiple factors be it one affecting the observer or one that arises from the subject being observed.
This demonstrates perspective and at no point do you see something that is not there. The text is there, it says the same thing. It does not appear to move or distort but rather as you tilt the phone the same light is viewed from a narrower height due to angles and it can be read as though it is not stretched.
An optical illusion makes you see something that simply does not exist, for example this picture that makes you think you see red in spite of there being jo red at all. popularmechanics.com/…/theres-not-a-single-red-pi…

Remember those rooms where they have like a checkered floor and they’re angled and you put a short person in one corner and a tall person in the other corner, and it looks like the short person is taller than the tall person. Is that an illusion?

I have no context for this example, have a link? I’ve seen the crazy kitchen at the Museum of Science and Tech in Ottawa that has a similarly themed illusion, but in that one the floors are level but painted in a way that tricks your brain into thinking its angled, but its not, which is 100% illusion.
Thus what I am imagining for your example is that the floor is in fact angled, but the paint makes it look straight, so the short person is infact elevated above the tall person in a way you cannot tell, creating an effect where perspective due to a physical difference makes you think they are on the same level but the illusion provided by the floor messes with that, creating an illusion that is really just perspective.
But there is no trick in this post. You know you’re tilting the phone, there’s no illusion. Its pure angles and you’re completely aware of what is occuring, thus no illusion. The definition of illusion is pretty clear, what you are seeing must be false or erroneous.

That’s an unhelpfully restrictive definition of illusion that is itself illusory. An illusion is also:
A sensation originated by some external object, but so modified as in any way to lead to an erroneous perception; as when the rolling of a wagon is mistaken for thunder.
The text is hidden or revealed through a change in perspective. That is the illusion.

There is nothing erroneous about this perception.

It’s an optical illusion. By definition their isn’t generally anything YOU would call erroneous about any optical illusion, I’d guess. The fact that the text is difficult bordering on impossible to read at some angles is the perceptual error. Stop ignoring obvious interpretations to support your pedantic trolling.

I’m not trolling. This is simply not an illusion.

It’s an illusion because no one would ever really say that.

Haha, ok I can agree with that take.
