The company's research labs have designed a prototype of a mobile application that can be used by store goers to identify products and retrieve more information about potential products. The company is testing it now with a number of retailers.

"This is a neat way of providing customers with more information about products, which they would normally [research] on the Web," said Jill Puleri, IBM retail vice president. "It's also a way for a retailer to target and change behavior, and get some cross-selling and up-selling going with consumers."

If implemented, the technology could be one of the first commercial uses of augmented reality. is the process of overlaying a view of something with additional computer-generated information. Televised American football games, for instance, will highlight with computer graphics the exact location -- called the first-down line -- that a team must pass to continue playing. AR can be implemented in user headsets or, with IBM's technology, a smartphone's camera viewfinder.

The idea behind the app, according to IBM, is to help the retailer provide more information to the shopper while they are in the store, rather than letting the consumer return home after a store visit to further investigate products on the Internet, increasing the likelihood that they will buy the product online.

This is how it works: A user entering a store can download the application, register, fill out a user profile and then use the app to find out more data about products in the store that are of interest. The user would aim the phone toward a product of interest and the app will use the phone's built-in video camera to identify the product using image-processing techniques. The identification process might work similar to how QR (quick-response) barcodes are used today, though it would not require the product packaging to contain a barcode, and would allow the retailer, rather than the product vendor, to present the information about the product.
