![]() ![]() The researchers found that users who had previously taken a typing course actually had a similar typing behaviour as those who had never taken such a course, in terms of how fast they type, how they use their hands and the errors they make - even though they use fewer fingers. ![]() “Many informal tests allow users to practice the sentences, resulting in unrealistically high performance.” “The fastest users in our study typed 120 words per minute, which is amazing given that this is a controlled study with randomised phrases,” said co-author Dr Antti Oulasvirta, also from Aalto. The average user in the study typed 52 words per minute, much slower than the professionally trained typists in the 70s and 80s, who typically reached 60-90 words per minute. “This partially explains why self-taught typists using fewer than ten fingers can be as fast as touch typists, which was probably not the case in the typewriter era.” “Modern keyboards allow us to type keys with different fingers of the same hand with much less force than what was possible with typewriters,” said co-author Anna Feit from Aalto University. For example, errors where one letter is replaced by another are now more common, whereas in the typewriter era typists often added or omitted characters.Īnother difference is that modern users use their hands differently. Now, decades after the typewriter was replaced by computers, people make different types of mistakes. Most of our knowledge of how people type is based on studies from the typewriter era. “Crowdsourcing experiments that allow us to analyse how people interact with computers on a large scale are instrumental for identifying solution principles for the design of next-generation user interfaces,” said study co-author Dr Per Ola Kristensson from Cambridge’s Department of Engineering. The results will be presented later this month at the ACM CHI Conference on Human Factors in Computing Systems in Montréal. ![]() The strategy is well-known in the gaming community but has not been observed in a typing study. However, they also found that the fastest typists also performed between 40 and 70 percent of keystrokes using rollover typing, in which the next key is pressed down before the previous key is lifted. Unsurprisingly, the researchers found that faster typists make fewer mistakes. Participants were asked to transcribe randomised sentences, and their accuracy and speed were assessed by the researchers. Volunteers from over 200 countries took the typing test, which is freely available online. The data was collected by researchers from Aalto University in Finland and the University of Cambridge. ![]()
