Bob has just invented a fantastic device which, in a nutshell, can apply forces to the fluids in the inner ear. Immediately, he wondered what would happen if he paired this with a VR rig.
If a person is suspended in some sort of harness so they can't move around (and fall over; liability, you know), would such a device make it possible to "trick" the user into feeling that they are experiencing (or not experiencing) forces? For instances, could Bob create a racing simulation in which the player feels the vehicle take off, bank around corners, and come to a sudden stop? Could he create a microgravity simulation?
...or would other inputs (e.g. the way the player's limbs move) give conflicting "signals" such that all the rig does is make the player lose his or her lunch?
(Basically, this is an idea I had for "better" VR in a setting that has "magic". Unfortunately, this "magic" has a sharply limited energy budget; moving a lot of mass is impractical. Also, actually applying high forces to someone probably isn't the best idea.)
