I remember wondering if something like the Goldtouch Elite Adjustable existed when I first started testing ergonomic keyboards. It didn’t at the time, as far as I could tell, but now a connected yet adjustable split board is indeed a product you can buy. It’s a solidly-built board and the ball joint connecting the two halves feels like it will put up with a lot of use. A squeeze of the lever at the top of the keys lets you set the board just how you like, adjusting both the vertical tenting and the angle between the two halves. There’s no programming to speak of, just the ability to swap a few function keys like print screen and home.

"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
