A Japanese software keyboard for game consoles has a problem with the entry speed and widget size. In this article, we show JoyFlick that is a text entry method for an improved Japanese software keyboard. We evaluated the text entry speed and accuracy of JoyFlick. Also, we conducted an analysis of the user’s operations to study the tendency of the operations and verify the design of JoyFlick. The results showed the following tendencies: the user tends to tilt the stick to select the keys on the outer edge;the user tends to restore the stick to the neutral position between selections; the user tends to restore both sticks to the neutral position at the same time (M = 15.5 × 10−2s) at the entry of a character. Also, the results showed that the design of JoyFlick, which restricts the order of consonant and vowel selection prevents a part of mistaken entries. Moreover, we show the outlook of the application and the necessity of study in actual and several environments.
