Human Factors Engineering in Las Vegas

I couldn't put this book down - Addiction by Design: Gambling in Las Vegas by Dow Schull.  Something interesting on every page.  For example:

"A study titled Effects if Ambient Odors on Slot-Machine Usage in a Las Vegas Casino found that slot revenue rose by a full 45% in a gambling area where machines had been subtly treated with a certain pleasing odor while remaining static in another area that had been treated with a different but equally odor.  The author speculated that certain aromas produce an "affective congruence with the situational context," encouraging longer play; an odor, "when matched to a certain environment," can "precipitate actions.""

Check out the following for an advanced course - Designing Casinos to Dominate the Competition (maybe someday someone will write Designing Public Schools to Dominate the Competition) by Bill Friedman (who is like the Michael Jordon of casino design).
