The link is broken for me (403).

edit: this link seems to work https://dl.acm.org/citation.cfm?id=2925953

wish I could update the url, can only edit the title :/

A mod can do that for you.

This is cool work; however, whoever approved this as PUBLICATION should be shot.

No software in sight. This is especially bad since "machine learning" is cited as a cornerstone of the detection. Hardware papers behind paywall or not yet existing (and may never exist). Nothing even remotely useful for somebody to replicate or evaluate.

If this appeared on the web from a company other than Google, everybody would dismiss it as pure marketing fiction.

Maybe I'm being overly harsh, but one of the big problems with 60GHz type stuff is evaluation that what you have is reliably signal. Especially with "machine learning", who knows what the system is latching onto.

Have you seen the demonstration videos? Some of the applications look really cool and useful, and the hardware is in a pretty advanced state.

I think https://github.com/simonwsw/deep-soli is one way to use software with it

C'mon, man. It's been less than twelve months.

2016 was three weeks ago.

Given the accuracy, could it read your fingerprints while you're doing the gesture? From the paper, it looks like the average displacement accuracy is 0.4mm. I wonder if that's accurate enough to read your fingerprints. If it could, you could ensure that only your gestures are recognized and not someone elses!

Well, resolution for fingerprint scanners is roughly 500 dpi [0]; 1 in^2 = 645 mm^2; so.. maybe, I'm not sure!

But, that said, I believe there are many >1 mm^2 resolution features that can basically uniquely identify users, like, the shape of a hand (individual finger geometry, etc), the length of a limb, the particular subcutaneous layout of veins, face geometry, etc. It's interesting to ponder about, at least!

Currently looking around for cheap (and arduino-amenable) single chip radar systems whereby I might try to hack together a more low tech prototype of Soli

Or even a special carved ring, or sticker or something.
