Called Tesco Groceries, the glassware lets you search for products just by speaking. Say "OK Glass, find a product" and then whatever you're looking for – cheese, beer, milk, whatever – and it'll add said product to your virtual shopping basket.
You can also scan the barcode for something to add it to your basket. Just say "OK Glass, scan a product", and it'll ready itself. So next time you're running low on milk – or beer, or cheese – you won't have to fire up your mobile browser or open the Tesco mobile app to add it to your order.
The app also lets you see nutritional information of the products. In the blog post, Tesco says it's still developing the glassware based on feedback. If you take it for a whirl and think of some cool features, drop Tesco a line.
Six months ago, Tesco posted a video showing how the glassware could work. It seems pretty much unchanged.
Tesco has had a tough few months. At the end of last year, it was revealed it had inflated its accounts by £250 million to cover up its falling profits. As damage limitation, it sold off its Blinkbox streaming service and its broadband and voice call businesses to TalkTalk. It also announced plans to close 43 shops across the UK.
