    • There is disclosed an enhanced text entry system which uses word-level analysis to correct inaccuracies automatically in user keystroke entries on reduced-size or virtual keyboards. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting region. The actual interaction locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each interaction location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context. Likewise, in a virtual keyboard system, the keys actuated may differ from the keys actually associated with the letters of the word interpretations. Each such sequence corresponds to a complete word, and the user can easily select the intended word from among the generated interpretations. Additionally, when the system cannot identify a sufficient number of likely word interpretation candidates of the same length as the input sequence, candidates are identified whose initial letters correspond to a likely interpretation of the input sequence.
    • 公开了一种增强的文本输入系统,其使用字级分析来在缩小尺寸或虚拟键盘上的用户按键条目中自动校正不准确度。 定义了确定在指定的自动校正区域内检测到的每个输入序列的一个或多个替代文本解释的方法和系统。 击键的实际交互位置可以发生在与提出或提供用于选择的单词解释的实际字符相关联的特定键盘键区域的边界之外,其中从每个交互位置到每个对应的预期字符的距离通常可以随着 语言或特定语境中预期词语的预期频率。 同样,在虚拟键盘系统中,致动的键可能与实际上与字解释字母相关联的键可能不同。 每个这样的序列对应于一个完整的单词,并且用户可以容易地从生成的解释中选择预期的单词。 此外,当系统不能识别足够数量的与输入序列相同长度的可能的词解释候选时,识别候选,其初始字母对应于输入序列的可能解释。
