User Centric Inc, a consulting company that specializes in incorporating user experience into design, did a study in comparing the texting experience texting experiences of iPhone owners and non-owners across devices and found out that iPhone owners make more typing errors than owners with QWERTY keyboard.
“When compared to hard-key QWERTY phone owners using their personal phones, iPhone owners’ rate of text entry on the iPhone was equally rapid. However, iPhone owners made more errors during text entry and also left significantly more errors in the completed messages.
While iPhone owners made an average of 5.6 errors/message on their own phone, hard-key QWERTY owners made an average of 2.1 errors/message on their own phone, p < .01. iPhone owners also left an average of 2.6 errors/completed message created on the iPhone compared to an average of 0.8 errors/completed message left by hard-key QWERTY phone owners on their own phone.
Interestingly, when comparing the performance of iPhone owners and novices (non-iPhone owners), there was no significant difference between the number of errors made, p = .21. iPhone owners were faster than non-iPhone owners, of course.
“Despite the correction features available on the iPhone, this data suggests that people who have owned it for a month are still making about the same number of errors as the day they got it,” says Gavin Lew, Managing Director. “
