Typing speeds on smartphones are catching up with physical keyboards, according to a large study of users on touchscreen handsets.
“We were amazed to see that users typing with two thumbs achieved 38 words per minute on average, which is only about 25% slower than the typing speeds we observed in a similar large-scale study of physical keyboards,” said Anna Feit, a researcher at ETH Zurich, and one of the co-authors.
“The given understanding is that techniques like word completion help people, but what we found out is that the time spent thinking about the word suggestions often outweighs the time it would take you to type the letters, making you slower overall,” said Sunjun Kim, a researcher at Aalto University.
The findings also revealed a generational difference, with 10 to 19-year-olds typing 10 words more per minute than their parents’ generation in the 40 to 49-year-old bracket.
“We are seeing a young generation that has always used touchscreen devices, and the difference to older generations that may have used devices longer, but different types, is staggering,” said Antti Oulasvirta, professor at Aalto University.
Almost three quarters (74%) of people use two thumbs when typing on a smartphone, and the quickest to take part in the study managed to notch up 85 words per minute.
And the speed of typing on smartphones only looks set to get even faster, with Apple recently adding swipe typing on its iOS 13 operating system, allowing users to glide their thumb to each letter without lifting.
ETH Zurich worked on the research with Aalto University and the University of Cambridge, and will present their findings at the MobileHCI 2019 conference in Taipei, Taiwan.
