Right after getting it, I put it my new phonecam to good use when I surreptitiously snapped a picture of this Restaurant Behavior Management (RBM) system being field-tested at the Vietnamese restaurant near our house in DC.
Apparently, it's designed to keep toddlers subdued while their parents eat a normal meal. It accomplishes this via dual audio/visual sensory projection [note the headphones and a screen-like device]. The taller tester [R] had the short one [L] pick from a stack of black boxes, each containing an identically sized iridescent disc. The chosen disc [I heard them calling it a "lan-king" or something] was then inserted into the RBM; when it was activated, the subject was rendered completely inert throughout the meal.
I looked around to see if any product like this had been released on the market, but I came up empty. I did find this Panasonic LS55 portable DVD player with a 7-inch screen. It's sweet, has long battery life and got great reviews, but I'm sure that no one would ever jack his kid into a DVD player and ignore him completely when they went out to eat, right?
I'll keep researching this revolutionary new product and let you know.
