Your shopping cart has a suggestion

HAWTHORNE, N.Y. — You just want to get a piece of fish and the makings of a salad, but your shopping cart keeps talking to you.

There's a nice white wine in Aisle 6 that would go perfectly with your salmon, it beeps. Your favorite brand of salami is on sale and, by the way, it's been six weeks since you bought toilet paper.

Nightmare or dream come true, the smart shopping cart is coming soon to a grocery near you, along with an array of other gizmos designed to make your trip to the supermarket more efficient and profitable — and to keep you coming back.

Researchers at IBM recently assembled several of the high-tech machines for a demonstration at their Industry Solutions Lab in Hawthorne. Among them were the smart shopping cart, a computerized produce scale called "Veggie Vision," and a fascinating projection tentatively dubbed the "Everything Display."

Some are being tested in stores while others are in various stages of development. Other companies including NCR, Fujitsu and Hewlett-Packard are also working on similar products, sometimes in partnerships.

"We'll see more change in the next five years in the way people shop than in the last 20," said Dan Hopping, a consulting manager with IBM who specializes in store operations and merchandising.

Kate Delhagen, a retail analyst with Forrester Research in Atlanta, said that until now, most shoppers have seen high-tech applications only at the checkout counter, with its credit card swiper and bar-code scanner.

"But now, the number of applications is multiplying and consumers are becoming more familiar with computer interfaces. So there's a lot of experimentation, a lot of gadgets and gizmos, a lot of high-tech things happening in a lot of different stores."

Many of the applications can be used in any retail setting, but grocers especially are "under tremendous pressure right now to create a better in-store experience for their customers or they're going to lose them on price to Wal-Mart," she said.

The smart shopping cart looks like a normal one except for an interactive screen and scanner mounted near the shopper. Once the shopper swipes his store card, his shopping history is available for all kinds of purposes, from presenting a suggested shopping list to alerting him to discounts or reminding him about perishables purchased a month ago.

If the customer scans her purchases herself for self-checkout, the cart will know about the salmon she just bought and can suggest a wine or a recipe.
