A Study of Variations of QWERTY Soft Keyboards for Mobile Phones
نویسندگان
چکیده
Three recent Qwerty soft keyboard variations are studied: Curve (equivalent to Swype), T+ (equivalent to SureType), and Octopus (equivalent to the Blackberry Z10 keyboard). In an experiment with 12 participants, the Octopus keyboard surpassed the standard Qwerty keyboard by the 4 th phrase entered, reaching an entry speed of 70 wpm on the 9 th phrase. The standard Qwerty soft keyboard had a mean entry speed of 54 wpm. The Curve is shown to be the least efficient of the Qwerty variations with a mean entry speed of 35 wpm. It is also the most error prone of the four keyboards. The T+ keyboard is shown, through the power law of learning, that it can surpass the standard Qwerty keyboard in entry speed after about 19 phrases of input.

متن کاملText entry using soft keyboards
Text entry rates are explored for several variations of soft keyboards. We present a model to predict novice and expert entry rates and present an empirical test with 24 subjects. Six keyboards were examined: the Qwerty, ABC, Dvorak, Fitaly, JustType, and telephone. At 8± 10 wpm, novice predictions are low for all layouts because the dominant factor is the visual scan time, rather than the move...
