Google Glass and grocery shopping seem to have a bright future ahead of them as this seemingly futuristic device wins over more enthusiasts among shoppers. Some of them tout Google Glass as a brilliant tool to generate grocery lists, while others use it to hunt for better deals.

Retailers are quick to spot the emerging trend and respond to customers' new needs. British giant Tesco seems to be on its way to become one of early adopters of Google Glass in supermarkets. However, the supermarket chain thinks in long term, trying to find new ways of using Google Glass, not just creating grocery lists and comparing product prices.

According to Tesco CIO Mike McNamara, customers may not use the device to do all their grocery shopping. What he counts on, however, is a growing popularity of Google Glass when it comes to ordering single products, for instance a bottle of milk. It all boils down to designing a smart Google Glass application, which can be for grocery delivery services. How does it work exactly? Tesco has actually come up with a video, which represents some sort of simulation of a real life shopping scenario, involving a pair of wearables and a gallon of milk. From what can be seen in the video, the solution seems to work fairly well.

Off to a shopping spree with a pair of wearables

That being said, one of Google Glass' unquestionable strength is that it enables a user to ditch a piece of paper with an often undecipherable checklist and replace it with a shopping list right there on a heads-up display. It beats smartphone lists, too (no need to look down and up from a mobile's display when shopping). It may be an awesome device, but how many people are willing to splash for a gizmo that costs over a thousand dollars just to substitute a post-it note with a virtual list? Here comes Evernote, a popular note-taking application, which can also be used to generate shopping lists integrated with photos and voice memos. The newest demos of Google Glass included the mention of Evernote as one of the possible add-on features.
How can Google Glass be used on a shopping expedition? If you do shopping with your significant other/ friend/ relative, etc., as each of you grabs a product off the shelf, you can command Google Glass to strike it off the list. Consequently, the other shopper will be able to immediately see that this product is already in the cart. But it is not the only way to coordinate shopping efforts with this device. Google Glass enables a confused shopper who was sent to a store to buy a certain product to launch a video call to get some help from others. They will get a look at the shelf and tell you what kind of, say, washing powder, you should buy.

Price comparison at a glance

Smartphone-wielding shoppers can compare prices in-store, typically by scanning the product's barcode. Smartphone already allows you to do instant price comparisons at the store, usually by scanning a barcode. Some of these apps may be also available for Google Glass. Users could then compare prices by picking a given item and glancing at its barcode. There is also Google's own shopping application, which can recognize covers of books, compact discs and DVDs without a need to process a product's barcode. All the users will need to do to see whether a selected product may be purchased for less online is to quietly utter a command. Suddenly they will see a number of price comparisons via their Google Glass device. Furthermore, they may have access to reviews if they wish to get credible evaluation of the product.
