Experiment #1(fast) Experiment #1(slow)
This experiment demonstrates that the human visual perception solves correspondence problems by equating them to what is likely to occur in the real world. For this reason, in the above demonstration the dots, (assumed to be solid objects) demonstrate horizontal motion, as opposed to cross motion, since they would collide in the real world and never reach their intended destination if they were to cross.
Experiment #2(fast) Experiment #2(slow)
I created this second experiment to make sure that apparent motion follows
rules of the real, physical world. The two dots above the horizontal bar bend
around the vertical bar, (as expected) but the dot on the bottom left does NOT
appear to be connected with the dot in the middle even though it is closer than
the bottom dot on the right. Thus it is not the closer correspondence, but the
further one that is being perceived since our brains are applying the knowledge
that solid balls can not pass through a solid bar.
