Wait what..? Is it that good? That's even more terrifying
- orangepurple 4y agoThankfully I use an extreme custom keyboard layout so I wish them luck.
- wholinator2 4y agoWell I think with enough time you could just use the key press model to try different configurations until you got one that gave intelligible results. The process could be easily automated if the resolution is enough to support accuracy in the 90th percentile
- ilyt 4y agoThat's about as hard as decrypting substitution cipher. Just think about the problem for a second, you will figure out how to trivially go around it.
- eurasiantiger 4y agoThat’s just as secure as ROT13
- heavenlyblue 4y agoDo you also have your number keys remapped non-linearly?

WiKey achieves more than 97.5% detection rate for detecting the keystroke and 96.4% recognition accuracy for classifying single keys. In real-world experiments, WiKey can recognize keystrokes in a continuously typed sentence with an accuracy of 93.5%.
