Many text entry methods are available in the use of touch interface devices when using a screen reader, and blind smartphone users and their supporters are eager to know which one is the easiest to learn and the fastest. Thus, we compared the text entry speeds and error counts for four combinations of software keyboards and character-selecting gestures over a period of five days. The split-tap gesture on the Japanese numeric keypad was found to be the fastest across the five days even though this text entry method produced the most errors. The two entry methods on the QWERTY keyboard were slower than the two entry methods on the numeric keypad. This difference in text entry speed was explained by the differences in key pointing and tapping times and their repitition numbers among different methods.
