Touchscreens are small, slick, responsive, and ubiquitous these days but it wasn't always the case. While touchscreens were and have been sold since the early 80s, YouTube channel takes a look at one of the earliest successful attempts at a mass-produced touch screen, the IBM 8516 Touchscreen CRT Monitor from 1992.
The screen can't quite keep up with speeds, going to fast or too slow makes it finicky. Fitting for a machine that was used in train stations and in informational kiosks at the 1992 Barcelona Olympics, it works great with large, general spaces on a screen. Try to get too specific, though, and you'll end up frustrated. We've made a little bit of progress since then.
