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!
- pizza 10y agoWell, 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 [0] http://www.neurotechnology.com/cgi-bin/fingerprint-scanners.cgi http://www.neurotechnology.com/cgi-bin/fingerprint-scanners....
