Using resonance to stimulate the vestibular system
So I just finished watching one of the unity talks that mentioned trying to find a way to make the player feel as if they are moving, and of course, he mentioned the Palmer experiment of frying your brain...
It got me thinking.. I remember a Myth Busters episode that they took small carpenter hammer, attached it to a mechanical arm, that beat on a beam of a bridge. Since they matched the resonance (frequency) of the bridge with the hammer, they were able to make the bridge sway to almost collapsing.
So.. we should be able to do something similiar? A quick google search revealed this study in ScienceDirect: http://www.sciencedirect.com/science/article/pii/S0304394008011130
The basic theory is that you can use a frequency tone to stimulate the vestibular system. Using HRTF, you could then potentially introduce a phenomena that makes it seem like the person is actually moving in the direction, or the opposite direction, of the sound?
Of course, the player would need to own a headset even capable of this low range frequency, but it should be investigated nonetheless in my opinion.

- I found a more complete full article containing related information.
Vestibular evoked myogenic potentials using low frequency stimuli:
http://www.scielo.br/scielo.php?pid=S1808-86942011000600005&script=sci_arttext&tlng=en
It claims that males and females may respond differently...
They claim that frequencies near 500Hz have a higher response amplitude, so normal headphones may suffice. Of course, they are measuring myogenic muscle potentials rather than subjective VOR. - For the complete seated vehicle experience this is a must, I don't think we should even pursue walking until we have the matrix.
- Would something like this sort of thing work? How this noise stimulates the sense of falling? https://www.youtube.com/watch?v=u9VMfdG873E
- cmeindaclub, cool video, saviornt, good out da box thinking, anytime someone start talking about vibratory physics, my mind goes to Keely (who some say Tesla borrowed heavily from) and I am up here in Tacoma and drive over the Tacoma narrows bridge frequently (the bridge that did collapse from vibratory physics and made all the smart engineers look silly - LOL!) In fact I think I remember Tesla saying these same memes could be applied to planet earth, and like the Tacoma narrows bridge shattering, we could shatter the entire planet earth with similar technology!

Dr. Horribles sing a long blog
So what if some Dr. Horrible wanted to split planet earth with vibratory physics the way Tacoma Narrows Bridge was destroyed? Would you guys support an NSA trying to stop an evil raven from snowcrash then if the whole planet was gonna be split?

So Keely just posted this article, about using ultrasound to MOVE real objects, they transported a toblerone bar. So maybe similar technology can be used to enact on the bones in our ears? To pull them in certain directions so they will sync with motion in our VR games, making us not get so nausea? Let me contact Marley Magner of Berklee school and see if I can't get his brilliance on this problem too. http://www.marleymagner.com/
Maybe that was some of that top s3cret VR audio stuff he was talking with Sessler

Samsung already has portable mobile ultrasound http://www.engadget.com/2014/03/14/samsung-galaxy-core-advance-usability-accessories/ - Call me old school but I will stay away as much as possible from any direct "shake" and/or "bake" solutions for my "head gears".
And in time .....after someone invents a 3d image generation with use of Phosphene and entoptic phenomena....I might give it a try... "JohnyX" wrote:

Regarding old-school phosphene experiments, when I was a child, I built a high-voltage low-current A/C "shocker" using a D-cell battery, a small electric buzzer (like a relay wired to oscillate), and a vacuum tube audio transformer wired in reverse to transform the low voltage pulses into high voltage. We would hold hands in a ring, with the shocker in the circuit, and see who would let go first (usually the squeeking girls).
Anyway, once at home, I did an interesting phosphene experiment by placing the wires of this device to the temples of my head (between eyes and ears), one wire on each side of my head. The technicolor light show was fantastic! However, the shocks were annoying so it only lasted a few seconds.
I accidentally over-stimulated my phosphenes years later when the wooden base of my 15-KV neon-sign transformer jacobs ladder carbonized from arcing, and I woke up on the concrete floor after some unknown period of time "snow blind" (all optic nerves stimulated to full potential), with a blinding white solid field everywhere in my FoV. After a few minutes, a few pinholes of snow (much like the snow from a weak TV signal on an old analog TV) appeared, moving around, growing in number. I realized those pinholes were my vision returning as the nerves began to relax from overstimulation. In about 15 minutes, the snow solidified into a full FoV of normal vision.
Luckily, I did not crack my head open when I fell unconscious to the concrete floor.
Cool, huh?
I have many such stories to tell, showing I must have a guardian angel to be here to tell my stories. It is amazing what I have survived, being such an inquisitive fellow all my life, but that can be hard to swallow for some people. Some of my stories are too fantastic (but completely true) and will surely bring the trolls out of the woodwork to call me a liar and show shameful disrespect, so I am not yet prepared to share them with the world.- Yes...one time back in former ussr by accident I got my hand in a broken 220volt light socket....not sure about vestibular system...but that was most painful fireworks ....world exploded in bright light ...I was thinking world is burning. After my brother pulled me off ...just a small blister like dot on my hand. I guess that was my first experience with "enhanced" virtual reality :shock: .
