[Xmca-l] Re: imagination and controlling the perception of visual illusions.
In the London tube (underground) trains _can_ come from the right with
respect to the platform -- at least, I do have memories of them doing so
for _certain_ platforms. But on the whole I think they usually come from
With respect to the construction of this particular illusion, I think that
the speed of the train is a function of the step in the image sequence,
which is a function of a necessarily disparate gap between frames so that
there is no obvious continuity of the people/distinct objects within the
train. So I suspect the impression of the train speed is coincidental and
not related to real speeds (other than not being too obviously fast).
I haven't looked at it for long, but what I've found is that the train (for
me) first goes away from the platform, it takes me a short while to bring
it back the other way (maybe 5 seconds), then after a few seconds to switch
to outbound again, and thereafter I'm able to switch it back and forth with
relative immediacy aided with a bit of imagination.
