english: What was interesting is, by videotaping on a bus, they were able to produce exactly what people on their smartphones were typing, and then they had a surprising result, which is that their software had not only done it for their target, but other people who accidentally happened to be in the picture, they were able to produce what those people had been typing, and that was kind of an accidental artifact of what their software was doing.
non_english: Zaujímavé bolo, že zo záznamov v autobuse presne zistili, čo konkrétny človek na svojom smartfóne píše. Prekvapivé bolo, že ich softvér nezachytil len cieľovú osobu, ale aj ostatných ľudí, ktorí sa náhodou dostali do záberu a pomohol im zistiť, čo títo náhodní ľudia písali na svojich smartfónoch. Bol to vedľajší produkt ich softvéru.
