We humans are pretty funny. The sensitivity comes a lot from what the eyes see, the hands feel and what we expect to happen from what the experience tells us (stick movement and such). Only a small ammount of it comes from the inner ear balance sense.

Try standing on one leg. Then close your eyes. Or try walking in a very dark but not completely black room. And then close your eyes. Your balance sense might tell you very strange things and if you haven't trained for this, you might fall.
