<p>Fascinating! I haven't been able/inclined to follow the
literature closely in Piezos and the implications for
proprioception and inertial sensations for years. When I
started in VR work, almost nothing was known about pressure/touch
and even less about proprioception/inertial sensations. Vision,
sound, touch, even olfaction had decades of understanding at the
sensor level and well beyond. Space medicine had a small handle
on some things, being able to and needing to study the human body
outside of the internal stresses from gravity.</p>
<p>I found this fairly good summary of the topic circa 2017... I
think they say that piezo1/piezo2 were discovered in 2010. Fast
moving field!<br>

<p>I have mild synaesthesia which is part of what has fascinated me
with VR... the most eerie experiences in VR environments I have
had were associated with this. I remember acutely walking into
the heart of a simulated stellar core floating in space in the
LANL CAVE circa 2004... the first time I did it, the false-color
encoding was on the warm end of the spectrum (yellow through red)
and while it was fascinating to "feel" the sheer and even coriolis
forces implied by being *visually* (only) immersed in the
evolving, spinning "particles". The second time was hugely
different as the researcher doing the work wanted to look at a
different set of physical properties that were encoded in the
cooler range (green-violet) and as soon as I stepped into the
volume that the star was filling and the particles were "flowing
past me", I felt, and even *smelled* a strong impression of cool
moisture. I know/knew it was entirely synaesthetic and/or my
higher cognition imposing on my lower sensory functions a model
fit. My eyes told me I was in a "cool mist" and by golly my skin
and sinuses decided it was easier to just agree with that rather
than argue the point. For weeks, whenever I had the opportunity
to show someone this model in the CAVE I would watch them closely
to see if they had a similar (un-prompted) experience. I never
saw anyone else do what I did, which was to pause, reach out and
"feel" the mist on my forearms, and then breathe in (through my
nose) the "cool particles". When prompted ("do you feel a cool
mist?") a few would offer a mild (polite?) acknowledgement, but
most were opaque to the experience I had. I also experimented
with adjusting the color palette and found that once sensitized
(prompted, expecting, etc.) that I could "feel" the warm particles
as well, especially when shifting from the "cool" spectrum to the
"warm" end. I guessed that this difference was primarily due to
a scarcity of real world precedent in the warm, similar to a "cool
mist"... maybe people in equatorial regions experience a "warm
rain" similar to my "cool mist" but I've never had the pleasure.</p>
<p>What is your stake/interest in the sensorium?</p>
