On Earth, for thousands of years, humans have adapted to the uneven surfaces of bodies of water, by developing the ability to compensate for shifting flooring. The common term for this adaptation is "sea legs".
As GW Johnson (and many others) develop concepts for rotating space craft to mitigate the harm caused by the absence of gravity, we can anticipate that the environment under foot will be characterized by movements that most humans would find unfamiliar.
This topic is offered for NewMars members who might find links to studies of this phenomenon. or who might wish to contribute personal experiences or observations.
The Coriolis effect will be present for all rotating habitats, and how well humans can adapt to that effect is unknown, beyond temporary experiences on amusement rides.
More unclear is the effect of changes in the center of mass of rotating objects, as mass moves around inside the rotating system.
To the best of my knowledge no human has experienced rotation in a planned rotating habitat. Humans ** have ** experienced rotation in orbit, but those experiences were most unpleasant emergency situations that were corrected as soon as possible.
It seems reasonable to suppose that if the mass of a rotating habitat is large compared to the mass of individual humans, the effect of movements of small masses within the rotating structure will be less noticeable than would be the case if the mass of the rotating structure is NOT large in comparison. My expectation is that human senses are going to detect even the smallest acceleration of the habitat surfaces.
It may be possible for modern computer animation to model the effects that I believe are likely to occur in the Real Universe.
This topic is available if a NewMars member develops animation along these lines.
An alternative is to place test equipment in orbit, to measure the forces that will occur inside the equipment as rotation begins, and masses move around inside the structure.
On Earth, it should be possible to build simulations of rotating habitats of various kinds. The dimensions are not extreme. A diameter of 56 meters is under consideration. The rotating ship design of RobertDyck has a radius of 37.76 meters, or diameter of 75.52 meters (247.8 feet).
For comparison, an American football field is 360 feet long.
An American baseball park is laid out as a quarter sector of a circle, the radius of which is 400 feet from home plate to the wall in center field.
Added detail: The regulation distance to the wall in left field is 325 feet, and the same is true for the wall in right field.
A bit of geometry should reveal the size of a circle that can be inscribed within that playing space.

I asked Gemini how large a circle would fit inside an American regulation baseball playing field.
It surprised me by showing that it has evolved to be able to handle simple geometry.
The answer is given as .414 .... The radius of the inside left wall from home plate is 325 feet. The radius of a circle that would fit inside the regulation playing field is thus 134.55 feet. The diameter of the Large Ship (per RobertDyck) is given as 247.8 feet, so the radius would be 123.9 feet.
Thus, the entire Large Ship habitat ring would fit nicely inside an American regulation baseball field.
The design I am working on is slightly larger, at 80 meters diameter, but it too would fit inside the American regulation baseball playing field.
The radius of the habitat is 131.234 feet, so it too would fit.
Google tells me that a Large Ship habitat ring would fit easily inside a typical Home Depot store.
300x300 feet > 90,000 square feet, and the Home Depot store average area is 104,000 square feet.
It appears that a warehouse with 90,000 feet of space is not unusual, but whether that space is uninterrupted is a question.
A rotating habitat simulation would need to be in a space that is free of support poles.
Update: A habitat simulation that runs on a track would not be inconvenienced by a support pole at the center.
Note: A rotating simulation need not be limited to one "deck". Some designs anticipate multiple decks, so there would be multiple levels of simulated gravity, but everyone will experience the same rotation rate.
It seems to me that a facility like this would be a natural fit for a major fixed location amusement park.
