Scientists from Finnish Aalto University, Cambridge University in the UK and the Swiss Higher Technical School of Zurich carried a large online test among 37,000 people from 160 countries. The main goal of the study was to find out which text input method is the fastest.
The results of the study showed that those who type on a smartphone with one finger can write 29 words per minute average. However, those who use two fingers are able to type 38 words per minute. It is worth remarking that some participants really surprised the researchers. One of them managed to type 85 words on a smartphone in one minute. For comparison, the average typing speed on a physical keyboard is 52 words.
The researchers also gave some tips on how to increase typing speed on a mobile device. They say, the use of autocorrect increases the speed by almost 9 words per minute, but the choice of phrases offered by the system slows down typing by 2 words per minute because of the need to distract on the proposed options.
