How the brain (might) encode large-scale three dimensional space - excellent review paper journal.frontiersin.org/arti…
"some subjects can smoothly track their own outstretched finger while in darkness, probably using [efference copy] and [reafference]" Cool.
also: it's very hard to read about how ocular muscles fire to control saccades w/o being very conscious of it happening & very distracted
The standard claim is that saccades are all about the fovea, but couldn't they also serve to sample the environment for peripheral vision?
"Normal saccades only appear to be ballistic because of their high velocities and brief durations." Leigh & Zee, 5/e
"Saccades are not truly ballistic, because they can be modified in mid-flight by factors presented just before the eye starts to move." Huh.
"The visual system is not surprised by eye movements because it receives a warning signal about each one." i.e., Corollary Discharge
more I think about it, more it seems super weird to track head but not eye movements - in the visual system, they're very tightly integrated
gorgeous: the connections b/w the semi-circular canals & ocular muscles - these drive the vestibulo-ocular reflex
Why do we call it "haptic feedback", but not "visual feedback"? Vision is also tightly responsive to our actions - it's just harder to tell
"near reflex triad" sounds like a particularly nerdy street gang
(it's actually vergence, accommodation, and pupillary restriction)
"only highly trained observers can make a smooth pursuit movement in the absence of a moving target" ncbi.nlm.nih.gov/books/NBK10…
The Voices of VR podcast with creators of Luckey's Tale exactly captures the process I want to accelerate and inform voicesofvr.com/107-paul-bett…
I may need to collapse what was gonna be two chapters into one long one. This is so different from typical treatments. Good sign, I suppose.
Fun fact: in the context of VR, it's v hard to discuss motion processing in he visual system without also covering eye & head movements.
Modeling Perception for VR - I’ve been thinking quite a bit about Michael Abrash’s powerhouse blog posts on... tmblr.co/Zqi6ol1dhGZmF
The New Visual Neurosciences is both an absurdity as a physical book and an amazing resource. Authoritative introductions on so many topics.
An excellent description of the subtleties in thinking about motion smear: why the camera analogy is dangerous tmblr.co/Zqi6ol1d3bUn7
Sweet talk by @tom_forsyth from Oculus Connect; great complement to the Best Practices Guide. static.oculus.com/connect/sl… youtube.com/watch?v=addUnJpj…
