Further note:

Such "tilting" of receptor apparatus is
Useful regardless of "sensory" or "motor"
modality.

And this general "rule" translates directly
to all Human-engineered "detector" ap-
aratuses.

In Physics, for instance, accelerator-
detectors would yield extremely-very-
much-more information if, instead of
being "stable", they were dynamically
"tilted" with respect to the source of
the "events" they were "detecting".

This, of course, is Hard to achieve
with respect to current accelerator-
detector designs, because the "de-
tectors" are, typically, quite massive.

There have to be ways, though, in
which the benefits of dynamic orient-
ation can be reaped, even in such
needing-exactness applications, and
these benefits will probably require
low-mass detectors, which is a benefit
in and of itself.

Other applications abound.

For instance, if "antennas" were engin-
eered to dynamically "tilt", this'd al-
low signal-processing that'd enable
extreme-precision in "reception".

In such "antenna" applications, there's
a Problem that correlates, in-scope
to frequency [wavelength] of the sig-
nals that're to be "detected" -- it's
Hard to move a physical apparatus
rapidly enough as frequency increases
and/or varies.

This Problem can probably be addres-
sed in the electronics -- by "tilting"
the functioning of the electronics, rather
than the physical "antenna".

In all cases, the results are exactly-anal-
ogous to the benefits that I described
in my earlier post.

1. in "sensory" ["receiving"] mode, the
"tilting" compensates for "signal"-to-
"receiver" Geometric "discrepancies",
yielding an accumulated "detection"
that converges upon "the signal".

2. In "motor" ["orientation"] mode,
the "tilting" allows a "signal" to be
"seen" from as many 'different' per-
spectives as there are "tilts" -- as
has been explained in AoK all along
with respect to turning a thing over
in one's hands until one "senses" its
complete 3-D structural-Topology.

And I'm not "tilting at windmills" :-]
