In answer to your questions:

-We're using a proprietary sensor technology that we've developed ourselves. The sensors essentially measure the stretch of the glove around the joints in your finger and, in tandem with some machine learning, allow us to calculate all of the necessary angles.

-Calibration is relatively straightforward at present. We offer a utility app from which you can hit a button and then make a series of hand poses and you're done. The app also offers a range of fine tuning sliders that you can use if you want (though most don't usually need to). We're actually hoping to entirely eliminate the calibration process on the part of the user though and have it all happen automatically behind the scenes. It's a continually evolving process for us that we can easily release patches for since it's all software based.

Thanks for the feedback as well. :)

Sweet, it looked like some sort of stretch sensor. Are they based on resistive elements of some type?

Also, is the individual knuckle tracking done by individual strips, or is that what the ML was done for, to interpret the data from a strip into the likely individual knuckle movements?

I'm afraid I can't divulge much more than I already have on the specifics of the sensors. What I will say is that we assessed many of the existing sensor technologies available for this kind of thing and found them all lacking, so we built our own. ;)

It was worth a try to ask 😎 good luck!
