A Thing I Learned

I discovered something interesting during this latest period of cold weather: I have touchscreen gloves.

I have to admit that I didn't even know these were a thing. I knew my usual gloves don't work on my cell phone to take photos of whatever, but I had no idea why. And I also have no idea where I got these gloves that do work with a touchscreen.

Gloves of mysterious origin. With hay on them, because I was feeding animals.

Poppy saw these gloves and asked me why some of the fingertips were white. I had no idea. But then, when I went out to walk the dogs* and wanted to to take a picture of the rime, I found that the white fingertips of these work on my cell phone screen.

As was this one.

This got me wondering why these gloves work with a touchscreen. What is it about a bare fingertip that registers with a touchscreen, but a typical gloved fingertip does not? And these gloves did?

A. theorized that it was the light color on the gloves' fingertips that the phone was picking up on. Eldest, however, looked it up, and it turns out that touchscreens pick up on our skin's natural electrical conductivity. So there's actually a charge going from fingertip to phone screen, which is blocked by normal gloves.

Touchscreen gloves, however, have conductive material in the fingertip to continue that charge from fingertip to phone. You can even make your own touchscreen gloves by sewing conductive thread into the fingertips of whatever glove you want.

I just thought that was cool. Always nice to solve a mystery, however small.

* When we have very cold periods like this, we move the dogs' crates from the sheltered but unheated shop into A.'s minimally heated office. They're not in there all the time, but enough that they have to be walked out of the property for potty breaks occasionally. This means that the only time we have to walk dogs is in the very worst weather. It's very dramatic.
