The company expects the shelf to help funnel more of the right products to the right consumers, and even convince undecideds to commit to an impulse buy by offering well-timed in-store commercials or coupons when the embedded weight sensor learns they've picked up an item. The move is almost certain to make it more difficult to resist junk foods.
Of course, what one industry tries, another could copy. Imagine if the produce aisle starts talking about the beta carotene in carrots. Then the problem won't be a matter of healthy foods getting squeezed out of the picture, but of consumers being bombarded with a cacophony of ads, all the time. Maybe we're not so far from "Minority Report's" vision after all.
