Whilst still looking straight ahead of you, stop your arm when you can no longer see your hand. You may be surprised how low your hand is at this point. Do same exercise but move your hand out to the side. Same surprise.  This procedure will exercise your peripheral vision, and will help you on the dance floor. A man can look straight ahead (keeping his head in his own space) and still see other peoples' feet and avoid bumping into tables and other couples.
Using your own arm for this exercise it not all that useful to get a 
feel for when you will notice something. Your brain knows where your arm 
and hand are, and so you "see" them on the periphery of your vision even 
when your eyes are not actually sending enough information to your brain 
to fully visualise them. This also happens for other people when you are 
aware of them, and they are doing pretty much what you expect, but is 
quite emphatically _not_ the case for someone else's foot suddenly 
appearing when you were not previously aware of it.
