How do I install iOS on any device?

Good afternoon.
A little while back, I was chatting with some developers who had actually ported iOS onto a pair of glasses—they were basically running experiments to see if they could turn standard eyewear into something genuinely high-tech.

Then there was this one company that supposedly integrated iOS into a lounge cushion, adding sensors for things like heart rate and body temperature.

I assume that’s pretty much how smartwatches came to be, too.

Anyway, does anyone happen to have a reliable resource that breaks down the actual process behind this?
Specifically, how one might go about installing iOS onto a non-standard device.

Thanks,

Here’s some light reading to get things moving:
