我们为智能手机提供了软键盘布局和新颖的文本输入系统。设计软键盘的主要问题是在非常小的触摸屏区域内安装大量按钮。这通常会导致用户不适和打字错误。我们建议的布局 TYPEHEX 键盘提供了全文输入功能，只需最少的手指移动。这个名字暗示了我们的愿景：使用六边形按钮实现更快的打字速度和更少的错误发生。与包含 27 个按钮的软 QWERTY 布局相比，我们提出的键盘只有 10 个功能按钮。主要的 5 个按钮呈六边形。它允许我们在一个按钮中放置 7 个字符（1 个字符位于中心，其他 6 个字符位于六边形的其余六个角）。在放置每个字母 (a-z) 时，我们考虑了字母频率数据、二元组和三元组，以确保频繁使用的字符、字符对和字符三元组放置得尽可能靠近。我们通过将运动时间模型（菲茨定律的应用）与语言模型相结合来评估我们的设计。计算出的食指和拇指的每分钟字数 (wpm) 值表明，我们的设计方法比软 QWERTY 和 T9 输入法提供了改进的 wpm 值。
We present a soft keyboard layout and a novel text entry system for smart phones. The major problem In designing a soft keyboard is to fit a large number of buttons within a very tiny touchscreen area. This often leads towards user discomfort and typing mistakes. Our proposed layout, TYPEHEX keyboard, presents full text entry facilities with minimum required finger movement. This name implies our vision towards achieving faster typing speed with less error occurrence using hexagonal buttons. While comparing with soft QWERTY layout, which contains 27 buttons, our proposed keyboard has only 10 functional buttons. The main 5 buttons are given hexagonal shape. It allows us to place 7 characters in a single button (1 in the center and other 6 are placed in six remaining corners of the hexagon). During placing each letter (a-z), we considered letter-frequency data, bigrams and trigrams in order to ensure that frequently used characters, character pairs and character trios are placed as close as possible. We evaluate our design by combining the movement time model which is an application of Fitts' law with the linguistic model. The calculated word per minute (wpm) values for both index finger and thumb shows that our design approach gives improved wpm values than soft QWERTY and T9 input method.
