If interaction alone collapsed the state, then when the particle-wave moves forward and passes through the material that the two slits are cut into, the wavefuction would touch and interact with THAT materiel/wall, and collapse, and not continue to propagate beyond it, would never pass through the two slits and interfere with itself as it continues propagating and then slap into the back wall where we see the interference pattern. It would collapse the moment it hit the original wall that the two slits are cut into.

It is not the case that "interaction" causes collapse, as "interacting" with that wall that the two slits are cut into does not collapse the wave-function. The only thing that causes collapse is a form of interaction where information can be collected/gained by an intelligent or conscious observer that can eventually gain information about the state. It is inherently tied to the gain in information from the experimenter and not tied to that gain in information of any non-specific material or measuring device.

How come quantum particles don't consider the paper (at the bottom of this illustration) an observation device, but cameras, eyes and photos it act's predictably for?

Me no think good but this is wierd right? Shouldn't the particles act in the observed manner if the paper itself is a tool to an observer?

At what moment does the wave-function collapses?

No dude. A particle is a fucking wave collapse.
