Motion: 7DMT vs Star Tours

[Patabel]

My DH can't ride Star Tours because of motion sickness....but has no trouble with Big Thunder, or any of the other coasters. From the description I've read of the 7DMT, it looks like you sway a lot (?). From those of you who have ridden both, how would you compare the two?
Thanks for any input!

I rode 7DMT three times recently and found little to no sway (unless we tried to rock our car--even then, miminal motion) on it. It's fairly comparable to BTMRR, only smoother.

Hi Pat.

The way I perceive the 'swaying' aspect of the cars (and I have not as yet ridden it), I think that would help to make it feel even smoother. I don;t see the cars swaying aimlessly in the various videos, but rather the cars seem to always remain flat as to the angle of the track. If the train is going around a banked turn (they all looked banked), the centrifugal force makes the free swinging car adjust itself as to the plane of the track. Sound confusing?

It is quite apparent here.....

You can see that there is little to no movement of the rider in the seat. You and Bob will enjoy.

If there's no problem with MTMRR there won't be a problem with 7DMT. The sway is very minimal and not noticeable unless you do it on purpose.

Thanks, Dan! Those videos were a great help...and your info not confusing at all! It's just Bob and me the next trip in October, and was trying to decide if I should snag a fp for both of us. I certainly will. That attraction really looks like fun.

There are basically two kinds of motion sickness.

One is induced by not being able to handle drops, inversions, loops, and/or just in general your body being thrown around. This is the type that true roller coasters cause. No matter how extreme the coaster, all of the brain's inputs (balance, visual cues) are actual and real.

The second type is induced by simulator rides. This has almost nothing to do with motion itself, but the simulation of motion. This kind of ride can have wildly different effects then roller coasters--many have no trouble with RCs but get green on the simplest simulator. Simulators attempt to fool your brain into believing it's doing things it really isn't by two main effects--small movements of the ride vehicle and visual cues. If the vehicle's movements are not well-synchronized with the visual cues--on the scale of a few milliseconds or less--then the human brain detects the disconnect and tries to figure out which to believe. If it can't reconcile the different inputs, that human is going to be sick soon.

Wow, Mesaboy2, that's quite the explanation! Makes sense I'm just glad I don't have either of those, and that my DH will be able to enjoy the new attraction!

I work in the simulation industry, so the question is kinda in my wheelhouse.
