Kinda sorta stuff

I bought two inexpensive appliances recently, and both have a very strange capability.

For instance, I bought the humidifier you see here. Delightful appliance but it has the weirdest controls. You don't actually have to touch the button to make it do things. You just sorta kinda touch it. Your finger literally doesn't need to make contact in order for it to respond. You just bring your fingertip near the button -- and it reacts. It's such an odd experience. I also bought a very cheap rechargeable light that has the same sort of controls.

So I guess this is a thing now, huh? We only need to come close to a device to make it work. I think I kinda-sorta like it, though you sometimes trigger the device when you handle it -- by moving it around the house, for instance. This can be irritating but on the whole, I approve.

Have you encountered this sort of thing? Do tell.
