My impression is similar to that of capsense touch buttons. Very cool, but I'd rather have physical buttons.

But I was proved wrong with touchscreens. For the longest time I thought that capacitive touch screen limitations would never be as reliable as resistive. They are sensitive to moisture and physical materials while resistive is not. But they've gotten really damned good. So, maybe...

Nice, but what would be an application where you'd need or want a single knob to behave so differently, as opposed to having multiple dedicated knobs, or a touch screen?

Well... a lot of times you wouldn't, but merely pick one and go.  And if you ever want to change the look and feel, just update the software and go.  Or it could be a user theme sort of selection, or an accessibility option to change the resolution/strength.  I would imagine that would sell reasonably well as an industrial module, though good luck getting buy-in from like automotive, they'll just copy it relentlessly... ::)

Like, lots of things are doing omni-wheels these days, and lots of things have used 2-5 button menu systems for a great while, usually with some up-down/left-right sense to most of the buttons, easily (intuitively) mapped onto a wheel like this.  Where such a single unified interface is chosen, you could well have different detents/ranges for menu navigation vs. scroll/range adjustments vs. on/off options.  Wide ranges needing precision could be multi-turn, etc.

And the demonstration is great, the narration syncing perfectly with the action, well planned and rehearsed.  I almost want to buy one. ;D

It's cool, but I'm feeling it lacks some kind of AI.

Wow, good idea. Some smart IoT knob, sending user action to a remote server, then getting back the info to be displayed on it, and the actions to be taken (and of course, all of that being logged on the server for the company's delight).
You could configure the whole thing on a web page connecting to your account. Brilliant!

As I often say: don't give them ideas. :-DD

... let alone any details!!



But it is a cool idea.  Edit:  The button, that is - NOT the IOT thing!!!

Of course we were exaggerating the trait here, but the amount of features kind of suggested going a bit further. And yes, the project is cool, but I still think it's a little too much for its intended purpose (a knob!), with many more potential failure modes than a single knob/rotary encoder, which is not good. Besides, when designing projects with knobs, one is a lot more likely to implement an ad-hoc GUI rather than rely on a specific GUI on the knob itself that may not match the GUI for the rest of the product.

So, I think it's like a bad good idea (or a good bad idea, if you prefer), but that's just my opinion.

Agreed, would be best with a more traditional GUI, as an input device to it.  The embedded screen isn't really even needed, but helps show amount or position or range, and perhaps what the quantity is if you're not keeping an eye on the main screen.

I don't think that it really fails?  If you make sure that the motor doesn't get stuck on, then it's still just an encoder sans detents.  As long as the GUI (on itself or elsewhere) is responsive, that's not too bad, certainly no worse than other things I've used.
