[simpits-tech] Motion...

[Stig Joergensen]

A couple of specs for you....

FOV : more than 220 degree

resolution : depend of the distance/size of the screen but more is
better (skip AA - the distance will be too great to notice, if the
resolution is high enough (ex. with 1600x1200 at 1.5' on 21",  AA dosnt
makes much difference) and i would guess that you could fill a 1.5x2m at
3m with 1600x1200 and still not see the difference. 

refreshrate : no less the 18FPS, a steady 25 will be sufficient....

that all i have at the moment...

Hi John,

Sorry to take so long to reply.  VR or simulated reality deals with the
complex relationships between the visual and motion cues.  While I'm
interested in motion platforms, I'm pursuing cues provided from a
G-suit,
and "helmet loader".  I find the literature a bit over my head,
particularly
when it talks about the physiology (i.e.. "vestibular response").  As an
engineer, "just give me the specs". :)  I'd like to nail down the specs
for
what mechanical/controls devices will deliver believable cues.

The commercial simulators are designed to deliver sufficient cues for
pilots
to be trained.  They're pilots and already know how it feels.  I want to
experience this as closely as possible, so have a bit different intent.

 I've got a good G-suit system working that feels good: fast
proportional
response that feels right when flying Falcon4.  I'm working on a
head-tracked HMD coupled to a "helmet loader" design:
http://pages.zdnet.com/johncraigrochester/vrvision/id12.html

Here are performance specs it would be helpful to nail down:

* Vision system's FOV, resolution, update rate (FPS)...
* Minimum helmet loader axes(DOF), force magnitudes, acceleration rates,
latencies
* Safety limits for preventing injury

Would you consider taking a crack at figuring out what performance
parameters might result in a system that will work?

Thanks,

Craig

Hello, I happen to be a neurotologist (Ear Nose Throat) who specializes
in
dizziness and Vertigo.....  I may be able to help with physiology of the
inner ear......
John Li, MD

I'm interested.  I nominate you for figuring out the Physio stuff(inner
ear). :)  I've got
to clear some things off my plate before I can commit much more than
time to
read. ;)  I'm interested
in the controls and hydraulics.

Craig R.
