Now, when they tried this on an iPhone 3GS, this is a graph of the perturbations that were created by the typing, and you can see that it's very difficult to tell when somebody was typing or what they were typing, but the iPhone 4 greatly improved the accelerometer, and so the same measurement produced this graph.
Da de prøvede det med en iPhone 3GS, er dette en graf over rystelserne som blev skabt af tastningerne. Og som I kan se er det  meget vanskeligt at afgøre om nogen taster eller hvad de taster, men iPhone 4 har et meget forbedret accelerometer, og den samme måling skabte denne graf.
