They wrote software to stabilize -- even though they were on a bus and maybe someone's holding their phone at an angle -- to stabilize the phone, process it, and you may know on your smartphone, when you type a password, the keys pop out a little bit, and they were able to use that to reconstruct what the person was typing, and had a language model for detecting typing.
De skrev noget software til at stabilisere -- og selvom de var med en bus og at nogle hold deres telefon i en vinkel -- til at stabilisere telefonen, behandle det og som I ved på jeres smartphone,  når i taster et password, talene vises et kort sekund,  og de var i stand til at bruge dette til at rekonstruere  hvad personen tastede, og havde en sprogmodel til at opfatte indtastningen.
