我们为智能手表提供了一种新的模棱两可的键盘布局，名为${t18}$。顾名思义，它由18个键组成，因此一个键可以对应多个字符。在这些情况下，系统根据词典选择其中一个字符。${T18}$键盘布局的灵感来自${T9}$，主要区别在于${T18}$的按键数量更多，并且它们以QWERTY布局排列。该方法被与OPTIME-T9进行了比较，OPTIME-T9是对智能手表原始${T9}$的改进。实验表明，与${t18}$相比，文本输入速度提高了39%。特别是，参与者使用${T18}$以15.7wpm的速度打字，使用Optimal-T9以11.3wpm的速度打字。
We present a new ambiguous keyboard layout for smartwatches named ${T18}$. As the name implies, it is composed of 18 keys, and for this reason a key may correspond to more than one character. In those cases, the system chooses one of the characters based on a dictionary. The ${T18}$ keyboard layout is inspired by ${T9}$, with the main differences being that ${T18}$ has a greater number of keys and they are arranged in a QWERTY layout. The method was compared to Optimal-T9, an improvement of the original ${T9}$ for smartwatches. The experiment showed a 39% advantage in text entry speed in favor of ${T18}$. In particular, participants typed at 15.7 wpm with ${T18}$ and at 11.3 wpm with Optimal-T9.
