This seems extremely rudimentary. I was hoping for at least some sort of high resolution pinscreen [1] technology with actuators, with a pixel at the top of each pin.

Seems lower resolution than the MIT Media Lab Inform project from years and years ago.

From the paper [1]:

> However, these existing approaches typically face multiple drawbacks which limit their proposed applications, including (i) surface discontinuities

Which cites the MIT inFORM project (3 in the references).

These articles should really just come out and say the obvious: these could be used to augment sexual experiences.

Is our future AI generated visuals and audio via VR goggles while under “3D touch” blankets?

… I mean, unlikely. For some people, perhaps, but I’d imagine it would always be very niche. Most people would presumably just, well, have sex.

Saw similar tech at Microsoft a decade ago. Use case I saw was to raise buttons on software keyboards. Here’s an article on the patent from 2010: https://www.sbs.com.au/news/article/microsoft-patents-bumpy-...

Still could be worth implementing, for switching major modes in apps. E.g. when browsing one may not need the alphanumeric keys, until a textfield is highlighted.

Easier alternative is manipulate the nervous system, i.e. extremely low power shocks, like how real life works. Or pneumatics.
