This study was conducted to compare the typing performance of subjects inputting random alphabet characters using software keyboards on touchpanel mobile devices and hardware keyboards (subjects n=67, 31.0 ± 11.1 years of age) Hardware keyboards showed significantly better performance for input speeds, error rates, and subjective rate of usability. As a result, even those who showed slow input spends using hardware keyboards, did not show much slower speeds in using software.
