Oliver Thomas has identical twins and an iPhone X. As you might expect, he made a video testing to see if one twin could unlock the iPhone X registered to the other twin.

The text went pretty much as you’d expect it to. But what I found really interesting was Oliver’s use of night mode in an old night-vision camcorder to capture the IR dot pattern put out by the iPhone X.

In the video, jump to about 30 seconds in and check out the spread of that pattern. It goes pretty wide, so much so that Oliver had to move one of the twins out of the spread to be sure he didn’t get a false positive.

The wide spread shows how far of a face detection reach the iPhone X has.

In addition, at that same place within the video, check out the pattern of the dots on the wall. They almost look like 5-pointed stars, rather than round dots. Is that just my imagination? Is there a shape to the dots beyond simple circles? If you know any of the detail, please do ping me.

In the meantime, check the video for yourself.
