In addition to a Sony PlayStation 2, the family has some special equipment: a S.M.A.R.T. BrainGames system that consists of a special controller, a helmet with built-in sensors for monitoring brain activity and a Smartbox that receives the brain signals.

But if a player’s mind wanders, the Smartbox sends a signal to the controller hindering acceleration or character movement in the game. —Mike Snider —Video games actually can be good for you (USA Today)
