US Navy will replace touchscreen with mechanical controls on its destroyers

I saw a touch screen for controlling AV equipment at Sun decades ago that had a single solenoid underneath the glass that could thunk to provide tactile feedback as you pressed buttons and dragged sliders.

I don't think they actually designed it, they just used it in one of their conference rooms.

By the way, are you "Le Jojo" of "Jojo on UI", or a different "that_jojo"? ;)

I've played with some tech demos that used electrostatic stiction (I may be remembering the name wrong) to create friction on a glass touch panel.

The high voltage needed makes it a no go for most/all portable devices.

I played with some other "cl controllable friction" tech but don't remember the basis of it. Iirc one actually made small indentations in the screen to simulate buttons. Had a bunch of limitations, I think the button placement was baked in at time of manufacturing, but it's been awhile and I don't trust my memory on the topic.
