LG has added a see-through door to its new Signature line of fridges that lights up when tapped, so you can check its contents without letting out the cold. And to save you the strain of actually physically opening the door when you see something you want, a simple foot tap now does that for you. It's a feature that first appeared on larger vehicles with lift-gates at the back, where tapping your foot under the bumper let you open it hands-free. And it works similar with LG's new Signature line fridge. On the floor you'll see a subtle 'Door open' projection and tapping your foot near it automatically opens the see-through side of the fridge.
The last thing you need when reaching for a snack is to burn any additional precious kilojoules, but the feature is also handy for those times when you're hands are full of groceries, or are just too dirty to mess up its stainless steel finish.
