english: Now that gave you a lot of information while someone was typing, and what they did then is used advanced artificial intelligence techniques called machine learning to have a training phase, and so they got most likely grad students to type in a whole lot of things, and to learn, to have the system use the machine learning tools that were available to learn what it is that the people were typing and to match that up with the measurements in the accelerometer.
non_english: tento nám poskytuje veľa informácií, zatiaľ čo niekto píše na klávesnici. Výskumníci potom využili pokročilú techniku umelej inteligencie nazývanú strojové učenie. V tréningovej fáze písali prevažne študenti kopu rôznych vecí a potom pomocou nástrojov strojového učenia, naučili systém rozpoznať, čo študenti písali a následne priradiť k tomu odchýlky namerané akcelerometrom.
