How does it work in practice? Do you have to scan an item when you put it in or take it of the fridge?
Because in practice, fridges look nothing like in the commercials. Very few people would put a whole apple and a carton of milk on a shelf and nothing more. That would be highly uneconomical, because there's far too much air that will escape when you open and close the door.
It is normal to have lots and lots of small boxes and other stuff stacked on each other which would make it hard if not impossble to operate a camera inside.
I've never used one other than demoing the features, but not well. The camera can't actually see what's inside the fridge. The camera sits between the two doors on the top bevel, pointing down.
As you cross the threshold of the fridge with your item, you have to pause to show the camera what you're putting in or taking out. If you don't pause, or if it just nondeterministically decides you weren't holding anything, it won't work. It has no idea where items are in the fridge, as soon as the threshold is crossed it loses sight of them.
There is one exception, and that's the fridge doors. The camera can't see that far up and out, but it takes multiple snapshots of the doors as you're closing them and bringing them within its field of view. The results are heavily distorted, incredibly low fidelity, and most likely very motion blurry. Too low quality for the fridge to even attempt to discern what's inside the door, it'll just show you the snapshot it took and let you figure it out by navigating Home > AI Vision Inside > Left Door/Right Door to see the low quality reconstruction of your door... or you could take that time instead to just open the door.
