Description

一种触摸屏键盘及其输入方法 技术领域  Touch screen keyboard and input method thereof
本发明涉及触摸屏的输入技术领域， 具体地说， 是一种触摸屏键盘及其 输入方法。  The present invention relates to the field of input technology of touch screens, and more particularly to a touch screen keyboard and an input method thereof.
背景技术 Background technique
目前已有触摸屏手机输入法大致可以分为四种： 按键式输入法、 手写式 输入法、 语音识别输入法和滑行输入式输入法， 它们各具优缺点， 具体如下: 按键式输入法作为现在的主流， 具有以下优点： （1 ) 照顾了传统按键手 机和个人电脑用户的按键输入习惯； （2) 识别、 录入一个字母或一组可能字 母的计算量、 时间、 能源等代价比较小。 尽管如此， 但是在手机等设备触摸 屏面积较小、 用户多以单手操作的情况下， 它也有其不足之处： （1 ) 按键布 局拥挤， 要看着键盘才能比较准确地点击； （2) 需要输入的 2个字母在键盘 上的距离较远时， 也必须移动较远的距离来输入； （3 )更适合 1根手指操作， 不方便多个手指分工协作。  At present, touch screen mobile phone input methods can be roughly divided into four types: push-button input method, hand-written input method, voice recognition input method and sliding input input method, each of which has its own advantages and disadvantages, as follows: Key input method as now The mainstream has the following advantages: (1) Taking care of the key input habits of traditional button mobile phones and personal computer users; (2) The calculation, recording, input of a letter or a group of possible letters, time, energy, etc. are relatively small. Despite this, in the case of a mobile phone and other devices with a small touch screen area and a user with one-handed operation, it also has its shortcomings: (1) The button layout is crowded, and it is necessary to look at the keyboard to click more accurately; (2) When the two letters that need to be input are far away from the keyboard, they must also be moved a long distance to input; (3) It is more suitable for one finger operation, which is inconvenient for multiple fingers to work together.
手写式输入法具有以下优点： （1 ) 直观的输入方式， 照顾了只会笔画书 写、 没有拼音等知识基础的人群； （2) 避免了按键式输入法按键布局拥挤， 要看着键盘才能比较准确地点击的缺点。 （3 ) 识别精度较高的情况下， 可以 减少选择的步骤和时间。 缺点： （1 ) 对许多 "提笔忘字" ， 习惯拼音打字的 年轻人来说， 不是一个好的选择； （2) 识别过程复杂， 需要很多计算量、 时 间、 能源等消耗； （3 ) 书写时间较长， 加之目前所有产品只提供了 1块手写 区域， 需要让用户等待较长时间， 以确认一个字已经写完， 浪费了较多时间， 并极大地降低了输入效率。  The handwritten input method has the following advantages: (1) Intuitive input method, taking care of people who can only write strokes, no pinyin and other knowledge bases; (2) Avoid button-type input method button layout crowding, to look at the keyboard to compare The disadvantage of accurately clicking. (3) When the recognition accuracy is high, the steps and time of selection can be reduced. Disadvantages: (1) It is not a good choice for many young people who are used to typing and forgetting words. (2) The identification process is complicated and requires a lot of calculation, time, energy and other consumption; (3) The writing time is longer, and all the current products only provide one handwriting area. It is necessary for the user to wait for a long time to confirm that a word has been written, which wastes a lot of time and greatly reduces the input efficiency.
语音识别输入法当下很热门， 它实现了 "会说话就能输入" ， 更好地适 应了更大的用户群体； 但是它的不足之处也很明显： （1 ) 必须让设备流畅地 接入网络， 否则就残废了， 并且会相应地消耗一些数据流量； （2) 对使用环 境和场合有挑剔， 背景声音太明显或者一些不适合讲话的场合， 不适用； （3 ) 输入内容须讲究， 如账号、 密码、 商业机密， 是不方便以讲话的方式来输入 的。 The speech recognition input method is very popular at the moment, it realizes "can speak and input", which is better suited It has a larger user base; but its shortcomings are also obvious: (1) The device must be smoothly connected to the network, otherwise it will be disabled and consume some data traffic accordingly; (2) The use environment And the occasion is picky, the background sound is too obvious or some occasions that are not suitable for speech, not applicable; (3) The input content must be exquisite, such as account number, password, trade secret, it is not convenient to input by means of speech.
滑行输入设计是最新的设计思路， 也是未来重要的发展方向。 其代表输 入法有国外 T9发明人 Cliff Kushler操刀设计的 Swype输入法和国内上海交通 大学的 Aeviou输入法。  The sliding input design is the latest design idea and an important development direction in the future. Its representative input method is the Swype input method designed by foreign T9 inventor Cliff Kushler and the Aeviou input method of Shanghai Jiaotong University.
Swype输入法使用 QWERT键盘布局， 通过在要输入的字母之间滑行， 以滑行轨迹拐点位置来识别相应字母， 实现了一笔输入一个单词的效果。 但 是， 它仍然规避不了按键式输入法的所有缺点： （1 ) 按键布局拥挤， 要看着 键盘才能比较准确地点击； （2 )需要输入的 2个字母在键盘上的距离较远时， 也必须移动较远的距离来输入； （3 ) 更适合 1根手指操作， 不方便多个手指 分工协作。 此外， Swype 输入法识别、 录入一个字母的计算量等代价也会比 较大。  The Swype input method uses the QWERT keyboard layout to recognize the corresponding letter by sliding the letter between the letters to be input, thereby achieving the effect of inputting a word. However, it still can't avoid all the shortcomings of the touch-tone input method: (1) The button layout is crowded, and it is necessary to look at the keyboard to click more accurately; (2) when the two letters that need to be input are far away from the keyboard, Must move a long distance to input; (3) More suitable for 1 finger operation, it is not convenient for multiple fingers to work together. In addition, the Swype input method will also cost more to identify and calculate the amount of calculation of a letter.
Aeviou 输入法目前主要是按照汉语拼音的规律来设计的。 在基本采用 QWERT键盘布局的基础上， 当滑到一个字母上时，其周边键位上的字母会变 成下一个可能的字母， 即是一种动态键盘。 它比起 Swype来说， 是以一条不 会交叉的滑行轨迹输入了一个或一组汉字。 它的缺点是， （1 ) 同按键式输入 法一样， 按键布局拥挤， 要看着键盘才能比较准确地点击， 以及更适合 1 根 手指操作， 不方便多个手指分工协作； （2) 因为动态键盘的特色， 识别、 录 入一个字母的计算量等代价比 Swype更大； （3 )极大地改变了用户对键盘和 键位的认识和习惯， 每次拐弯选择下一个字母时， 都必须 "眼观六路" 。 发明内容  The Aeviou input method is currently designed primarily in accordance with the laws of Pinyin. Based on the basic QWERT keyboard layout, when sliding on a letter, the letters on the surrounding keys will become the next possible letters, which is a dynamic keyboard. It compares Swype with one or a set of Chinese characters in a non-intersecting taxiing trajectory. Its disadvantages are: (1) Like the push-button input method, the button layout is crowded, it is necessary to look at the keyboard to click more accurately, and it is more suitable for one finger operation, which is inconvenient for multiple fingers to work together; (2) Because of the dynamic The characteristics of the keyboard, the recognition and the calculation of entering a letter are more expensive than the Swype; (3) greatly change the user's understanding and habits of the keyboard and the key, every time you turn to select the next letter, you must "eye" View six roads". Summary of the invention
本发明所要解决的技术问题是提供一种触摸屏键盘， 它将二十六个字母 分配于被组织成内、 外圈结构的分区上， 在不用明显改变个人电脑用户键位 习惯的情况下， 较传统的将二十六个字母分配于八个键上的 T9手机输入法具 有更高的字母定位精确度。 The technical problem to be solved by the present invention is to provide a touch screen keyboard, which will have twenty-six letters Assigned to the partitions that are organized into inner and outer ring structures, the T9 mobile phone input method that assigns twenty-six letters to eight keys is more conventional than without changing the user's key position habits. High letter positioning accuracy.
本发明所要解决的另一技术问题是提供一种触摸屏键盘的输入方法， 它 采用以具有足够滑行空间的任意点为起点， 向目标字母所在键盘分区设置的 角度范围滑行的方法进行定位和输入， 在实际操作过程中， 具有滑行空间大 及滑行精度要求低等优势， 适合广泛推广、 应用。  Another technical problem to be solved by the present invention is to provide a method for inputting a touch screen keyboard, which uses a method with sufficient sliding space as a starting point to perform positioning and input by sliding to an angular range set by a keyboard partition of a target letter. In the actual operation process, it has the advantages of large sliding space and low requirements for sliding accuracy, which is suitable for wide application and application.
本发明通过下述技术方案实现： 一种触摸屏键盘， 包括设有放置二十六 个字母的键盘分区结构， 为了提高输入效率， 所述的键盘分区结构由内圈和 外圈组成。  The present invention is achieved by the following technical solution: A touch screen keyboard comprising a keyboard partition structure provided with twenty-six letters. To improve input efficiency, the keyboard partition structure is composed of an inner ring and an outer ring.

L, I/0/P, Q/W/E. Compared with the existing Aeviou input method, the user is more convenient and quicker to adapt and use, and can be widely applied to touch screen devices such as mobile phones and palmtop computers. In order to better implement the present invention, a space bar, an input method switching key, an automatic word-making key, and a delete key are also provided around the keyboard partition structure; this positional arrangement also utilizes the limited space of the screen reasonably.
一种触摸屏键盘的输入方法， 其特征在于， 包括以下步骤：  A method for inputting a touch screen keyboard, comprising the steps of:
( a) 确定待输入的编码字母或常用标点符号， 以键盘上具有足够滑行空 间的任意点为起点， 使用单指或输入笔在屏幕上滑行， 滑行方向为目标字母 或常用标点符号所在分区设置的角度范围， 滑行距离根据用户习惯及手机屏 幕大小确定， 较短时为内圈分区的字母， 较长时为外圈分区的字母或常用标 点符号；  ( a) Determine the code letters or common punctuation marks to be input, starting from any point on the keyboard with sufficient sliding space, using a single finger or stylus to slide on the screen, the sliding direction is set to the target letter or the common punctuation mark. The range of angles, the sliding distance is determined according to the user's habits and the size of the screen of the mobile phone. When it is short, it is the letter of the inner circle partition, and when it is long, it is the letter of the outer circle partition or the common punctuation mark;
(b)屏幕上显示常用标点符号后， 点击待输入的标点符号， 即完成输入; 或者， 完成待输入英文词语或其他语言字词的所有编码字母的输入， 至屏幕 上出现相应的候选英文词语或其他语言词语的候选编码， 其中英文词语或其 他语言的候选编码由一个以上的编码字母组成； 此处， 将英文词语与其他语 言词语区分， 因为在输入法领域， 只有英语的字母是直接输入， 其他语言的 词语都得按照一定的输入法规则编码为一串英文字母， 直接输入英文字母后， 再按照该规则转换为相应词语， 从而完成间接输入， 所以英文词语较为特殊， 不存在编码的问题。  (b) After displaying the common punctuation marks on the screen, click the punctuation marks to be input to complete the input; or, complete the input of all the encoded letters of the English words or other language words to be input, and the corresponding candidate English words appear on the screen. Or candidate coding of other language words, wherein the English word or candidate code of other languages is composed of more than one coded alphabet; here, the English words are distinguished from other language words, because in the field of input method, only English letters are directly input. Words in other languages must be coded into a series of English letters according to certain input method rules. After inputting the English letters directly, and then converting them into corresponding words according to the rules, the indirect input is completed, so the English words are special, and there is no coding. problem.
( c ) 点击选中待输入的英文词语即可输入， 或者点击其他语言的候选编 码以显示对应的候选字词， 并在候选字词中点击选中待输入的字词完成输入。  ( c ) Click to select the English words to be entered to enter, or click the candidate codes in other languages to display the corresponding candidate words, and click the selected words in the candidate words to complete the input.
所述步骤 （a) 中滑行距离的确定方式为： 根据用户习惯及手机屏幕大小 设定临界值， 当滑行距离小于临界值时， 输入位于内圈分区上的字母， 当滑 行距离大于临界值时， 输入位于外圈分区上的字母或常用标点符号。  The step of determining the sliding distance in the step (a) is: setting a threshold according to the user's habits and the screen size of the mobile phone. When the sliding distance is less than the critical value, inputting the letter on the inner circle partition, when the sliding distance is greater than the critical value , Enter the letters or common punctuation marks on the outer circle partition.
根据事先确定的输入法， 所述步骤 （b) 中英文词语或其他语言的候选编 码由一个以上的编码字母组成； 若英文词语或其他语言的候选编码为两个以 上编码字母时， 后续输入的编码字母会与前面的编码字母自行配对为英文词 语或其他语言字词的候选编码， 若将英文词语或其他语言字词的候选编码的 全部编码字母输入后， 屏幕上仍未显示出待输入的英文词语或其他语言字词 的候选编码， 采用左边手指定住右边手指点击或右边手指定住左边手指点击 的双指手势， 来显示下一行或者上一行的英文词语或其他语言字词的候选编 码； 所述步骤 （c) 中点击其他语言的候选编码以显示对应的候选字词， 若待 输入的字词仍未显示在屏幕上， 则采用单指或输入笔在竖直方向内向下或向 上滑动来显示下一行或者上一行候选字词， 至待输入的字词出现， 点击选中 即可。 According to the input method determined in advance, the candidate code of the English word or other language in the step (b) is composed of one or more code letters; if the candidate code of the English word or other language is more than two code letters, the subsequent input The coded letters will be paired with the previous coded letters as English words. Candidate coding of a language or other language words. If all the coding letters of the candidate codes of English words or other language words are input, the candidate codes of the English words or other language words to be input are still not displayed on the screen. The left hand specifies the right finger click or the right hand specifies the double finger gesture of the left finger click to display the candidate code of the English word or other language word of the next line or the previous line; in step (c), click the candidate code of the other language. To display the corresponding candidate words, if the word to be input is still not displayed on the screen, use a single finger or an input pen to slide down or up in the vertical direction to display the next line or the previous line of candidate words, to be The entered words appear, click to select.
在所述的输入方法中还定义有双指输入方式， 其输入方式与实现操作对 应如下：  A two-finger input mode is also defined in the input method, and the input mode corresponds to the implementation operation as follows:
双指向左滑行： 有候选编码时， 删除最后一个编码字母； 无候选编码时， 删除文字输入区内光标前面的一个字符， 所述字符包括文字和标点符号等可 见字符， 以及空格、 制表符、 换行符等不可见字符；  Two-point left slide: When there is a candidate code, delete the last coded letter; when there is no candidate code, delete a character in front of the cursor in the text input area, the characters include visible characters such as text and punctuation, and spaces, tabs , line breaks, and other invisible characters;
双指向右滑行： 无候选编码时， 删除文字输入区内光标后面的一个字符; 双指向左下方滑行： 回车 /换行；  Double-pointing right-sliding: When there is no candidate encoding, delete one character behind the cursor in the text input area; Double-pointing to the lower left sliding line: Enter/line feed;

右边手指定住左边手指点击： 有候选编码时， 显示上一行候选编码； 无 候选编码时， 文字输入区内光标向前移一位。  The right hand specifies the left finger click: When there is a candidate code, the previous line candidate code is displayed; when there is no candidate code, the cursor moves forward one bit in the text input area.
本发明借鉴 T9输入法一键多字母、 五笔输入法字母分区、 二进制等的优 秀设计思路和方法， 继承传统 QWERT键盘的基本布局， 结合触摸屏支持手 势多样性的特点， 提出了一种新的输入键盘及其输入方法。 它在允许手写输 入法一样宽松的滑行空间的同时， 以较小的代价完成了高精度的字母输入。 加之与传统 QWERT键盘的良好继承关系， 所以世界范围内针对该键盘开发 的任意语言、 任意设计思路的输入法， 几乎都可以简单、 高效地移植到触摸 屏设备中。 The invention draws on the excellent design ideas and methods of T9 input method one-key multi-letter, five-stroke input method letter partitioning, binary, etc., inherits the basic layout of the traditional QWERT keyboard, and combines the characteristics of the touch screen to support gesture diversity, and proposes a new input. Keyboard and its input method. It allows high-precision letter input at a small cost while allowing a sliding space that is as loose as the handwriting input method. In addition to the good inheritance relationship with the traditional QWERT keyboard, the input method for any language and arbitrary design ideas developed for the keyboard can be easily and efficiently transplanted into the touch screen device.
本发明与现有技术相比， 具有以下优点及有益效果：  Compared with the prior art, the present invention has the following advantages and beneficial effects:
( 1 )本发明的键盘及其分区衍生于传统 QWERT键盘， 极大地照顾了世 界范围内各种语言背景和各类输入法使用习惯的用户， 减少了用户适应新键 盘所需的记忆量和时间， 易于快速上手。  (1) The keyboard and its partition of the present invention are derived from the traditional QWERT keyboard, greatly taking care of users of various language backgrounds and various input method usage habits worldwide, and reducing the amount of memory and time required for the user to adapt to the new keyboard. , easy to get started quickly.
(2) 本发明的配套定位键盘分区的手势， 只包括 2方面要素： 方向和滑 行距离长短。 因为与键盘分区有良好对应关系， 方便联想、 记忆， 加之不需 要对滑行起点有太多限制， 操作连贯性和舒适度感受明显。  (2) The gesture of the matching positioning keyboard partition of the present invention includes only two aspects: the direction and the length of the sliding distance.

以下所述仅是本发明的较佳实施例， 并非对本发明做任何形式上的限制， 凡是依据本发明的技术实质对实施例所作的任何简单修改、 等同变化， 均落 入本发明的保护范围之内。  The following are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any simple modifications and equivalent changes to the embodiments in accordance with the technical spirit of the present invention fall within the scope of the present invention. within.
实施例：  Example:
本发明提供了一种触摸屏键盘， 它区别于现有的 Swype滑行输入法以及 Aeviou滑行汉字输入法， 在结合传统 QWERT键盘习惯的同时， 还极大地增 加了单指滑行空间， 更不会出现交叉的情况， 使用户适应和使用都更加方便、 快捷。 本发明设有十二个分区， 如图 1、 图 2所示， 在这些分区上分配有二十 六个字母及常用标点符号。 十二个分区排列成内圈、 外圈分布的结构， 但是 在触摸屏上显示的形式不仅限于圆形， 可为椭圆、 正六边形等适合手机屏幕 的任意几何形状。 其中， 六个分区位于内圈上， 六个分区位于外圈上。 十二 个分区相当于十二个按键， 较传统的将二十六个字母分配于八个键上的 T9输 入法具有更高的定位精度。  The invention provides a touch screen keyboard, which is different from the existing Swype sliding input method and the Aeviou sliding Chinese character input method. When combined with the traditional QWERT keyboard habit, it also greatly increases the single finger sliding space, and does not cross. The situation makes it easier and faster for users to adapt and use. The present invention has twelve partitions, as shown in Figures 1 and 2, with twenty-six letters and common punctuation marks assigned to these partitions. The twelve partitions are arranged in a structure in which the inner ring and the outer ring are distributed, but the form displayed on the touch screen is not limited to a circular shape, and may be an ellipse, a regular hexagon or the like, which is suitable for any geometric shape of a mobile phone screen. Among them, six partitions are located on the inner ring and six partitions are located on the outer ring. Twelve partitions are equivalent to twelve buttons, which have higher positioning accuracy than the traditional T9 input method that assigns twenty-six letters to eight keys.
许多使用 T9输入法的用户都知道， T9输入法主要是应用于手机上， 其 字母分配规律如下： 数字键 1设有常用标点符号， 数字键 2设有 A/B/C, 数字 键 3 设有 D/E/F, 数字键 4设有 G/H/I, 以此类推。 其字母设置规律有别于 QWERT 键盘， 加之触摸屏手机软键盘没有按键手机硬件键盘凹凸有致的手 感， 所以在输入时往往不能不看键盘做到 "盲打" 。 本发明继承了 QWERT 键盘上字母的排列习惯， 在图 1、 图 2中分别示意了两种情况， 一种情况是： 设于内圈六个分区上的字母从最左边逆时针方向依次为 D/F/G、 C/V/B、 N/M、 H/J/K、 Υ/U/L· E/R/T; 在对应 D/F/G、 C/V/B、 N/M、 H/J/K、 Υ/U/L· E/R/T 外圈的六个分区上分别设有 A/S、 Z/X、 常用标点符号、 L、 0/P、 Q/W; 另 一种情况是： 设于内圈上的六个分区的字母从最左边逆时针方向依次为 F/G、 V/B、 N/M、 H/J、 Y/U、 R/T; 在对应 F/G、 V/B、 N/M、 H/J、 Y/U、 R/T外圈 的六个分区上分别设有 A/S/D、 Z/X/C、 常用标点符号、 K/L、 I/0/P、 Q/W/E。 在所述键盘分区结构的周边上还设有空格键、 输入法切换键、 自动造词键以 及删除键， 合理地利用了屏幕空间。 Many users who use the T9 input method know that the T9 input method is mainly applied to mobile phones. The letter distribution rules are as follows: The numeric key 1 is provided with commonly used punctuation marks, the numeric key 2 is provided with A/B/C, and the numeric key 3 is set. There is D/E/F, the number key 4 is set to G/H/I, and so on. The letter setting rule is different from the QWERT keyboard, and the touch screen mobile phone soft keyboard does not have the touch of the phone hardware keyboard bump, so it is often impossible to read the keyboard to "blind" when inputting. The invention inherits the arrangement habits of the letters on the QWERT keyboard, and two cases are illustrated in Fig. 1 and Fig. 2, respectively. One case is: the letters arranged on the six partitions of the inner circle are reversed from the leftmost direction to D. /F/G, C/V/B, N/M, H/J/K, Υ/U/L· E/R/T; in the corresponding D/F/G, C/V/B, N/M , H/J/K, Υ/U/L· E/R/T The six sections of the outer ring are respectively provided with A/S, Z/X, common punctuation marks, L, 0/P, Q/W; the other case is: the letters of the six partitions set on the inner ring are The leftmost counterclockwise direction is F/G, V/B, N/M, H/J, Y/U, R/T; in the corresponding F/G, V/B, N/M, H/J, Y /U, R/T outer ring has six A/S/D, Z/X/C, common punctuation marks, K/L, I/0/P, Q/W/E. On the periphery of the keyboard partition structure, a space bar, an input method switching key, an automatic word-making key, and a delete key are also provided, and the screen space is reasonably utilized.
本发明还提供了上述触摸屏键盘的输入方法， 包括以下步骤： 确定待输 入的编码字母或常用标点符号， 以键盘上具有足够滑行空间的任意点为起点， 足够滑行空间即是说只要保证能在所需方向和距离上滑行即可。 使用单指（1 根手指） 或输入笔在屏幕上向目标字母或常用标点符号所在分区设置的角度 范围内滑行， 滑行距离的确定方式为： 针对各分区设有距离临界值， 当滑行 距离小于临界值时， 输入位于内圈上分区的编码字母， 当滑行距离大于临界 值时， 输入位于外圈上分区的编码字母或常用标点符号， 同时目标编码字母 或常用标点符号所在的分区做放大显示， 以起提示作用。 屏幕上显示常用标 点符号后， 点击待输入的标点符号， 即完成输入； 或者， 完成待输入英文词 语或其他语言字词的所有编码字母的输入， 至屏幕上出现相应的候选英文词 语或其他语言词语的候选编码， 其中英文词语或其他语言词语的候选编码由 一个以上的编码字母组成； 若将英文词语或其他语言字词的候选编码的全部 编码字母输入后， 屏幕上仍未显示出待输入的英文词语或其他语言字词的候 选编码， 采用左边手指定住右边手指点击或右边手指定住左边手指点击的双 指（2根手指）手势， 来显示下一行或者上一行的英文词语或其他语言字词的 候选编码； 点击选中待输入的英文词语即可输入， 或者点击其他语言的候选 编码以显示对应的候选字词， 若待输入的字词仍未显示在屏幕上， 则采用单 指或输入笔在竖直方向内向下或向上滑动来显示下一行或者上一行候选字 词， 至待输入的字词出现， 点击选中即可。 其中， 距离临界值的设定能很好地区别相同方向上内圈分区和外圈分区 的滑行距离， 使实施更加容易、 操作更加简单。 其要求如下： 取触摸屏设备 竖放时宽度的 30%-70%范围内的某个具体值为内外圈分区的滑行距离临界 值， 当滑动起止点直线距离大于该临界值时， 则认为定位了外圈分区。 在配 合软件实现时， 还可以考虑每个用户滑动习惯的差异， 通过训练让软件自动 学习、 确定出更符合用户习惯的各个分区的内外圈距离临界值。 The invention also provides the input method of the above touch screen keyboard, comprising the following steps: determining the coded letters or common punctuation marks to be input, starting from any point on the keyboard with sufficient sliding space, sufficient sliding space means that as long as it can be guaranteed Slide in the desired direction and distance. Use a single finger (1 finger) or stylus to slide on the screen within the angle range set by the target letter or the common punctuation mark. The sliding distance is determined as follows: The distance threshold is set for each zone, when the taxi distance is less than For the critical value, input the coded letters on the inner circle. When the sliding distance is greater than the critical value, input the coded letters or common punctuation marks on the outer ring, and the target code letters or common punctuation marks are enlarged. , in order to play a role. After the common punctuation marks are displayed on the screen, click the punctuation marks to be input to complete the input; or, enter the input of all the encoded letters of the English words or other language words to be entered, and the corresponding candidate English words or other languages appear on the screen. Candidate coding of words, wherein candidate codes of English words or other language words are composed of more than one coded letter; if all coded letters of candidate codes of English words or other language words are input, the screen still does not display to be input Candidate code for English words or other language words, use the left hand to specify the right finger click or the right hand to specify the left finger click (two fingers) gesture to display the next line or the previous line of English words or other language words Candidate coding of words; click to select the English words to be entered to input, or click the candidate codes in other languages to display the corresponding candidate words. If the words to be input are still not displayed on the screen, use single finger or input The pen slides down or up in the vertical direction to show the next Or on line candidate word, the word to be input appears, click to select. Among them, the setting of the distance threshold can distinguish the sliding distance between the inner ring segment and the outer ring segment in the same direction, which makes the implementation easier and the operation is simpler. The requirements are as follows: Take a certain value of the range of 30%-70% of the width of the touch screen device when the vertical position is vertical. When the linear distance of the sliding start and end point is greater than the critical value, the positioning is considered. Outer circle partition. When the software is implemented, the difference in sliding habits of each user can also be considered. The training allows the software to automatically learn and determine the inner and outer circle distance thresholds of the various partitions that are more in line with the user's habits.
整个过程的工作原理如图 3所示， 当单指或输入笔在手机或平板电脑上 的触摸屏 （即图中 "触摸屏硬件" ） 上点击或滑动时， 可以从触摸单元获得 点击或滑动的屏幕坐标和滑动信息， 其中滑动信息包括手指按下或松开等内 容， 而这个触摸单元可以是触摸屏硬件驱动或操作***等软件设备， 上述信 息经过有效性判断单元的筛选、 过滤， 就会得到对进一步识别、 处理有效的 屏幕坐标和滑动信息。 利用得到的有效信息， 通过键盘分区计算单元的分析， 即可确定该滑动想要输入的分区及其表示的一组字母或常用标点符号 （即图 中 "字符组" ） 。 序列有效性检査与候选字词生成单元， 根据该分区以及此 前已输入的分区表示的字母或者常用标点符号， 进行完整的排列组合， 得到 长度相等的字母序列 （即是英文单词或者其他语言某种输入法的英文字母编 码） 或者常用标点符号， 但是因为并非所有这些字母序列在英文词典或者其 他语言某种输入法的词典中都存在且有意义， 所以必须参考词典中的数据对 它们的有效性进行筛选， 剔除没有意义的字母序列， 得出的有效字符组合序 列就是最后有意义的字母序列或者常用标点符号， 对于英语来说它们就是英 文单词和常用标点符号， 而对于其他语言来说它只是英文字母编码和常用标 点符号， 当然在参考词典筛选的过程中也能得到编码对应的字词和常用标点 符号。 字符组合序列即是上述英文单词或常用标点符号或者其他语言某种输 入法的英文字母编码， 将这些序列送到字符组合序列提示单元即可在屏幕上 显示出来， 同样其他语言字母编码对应的字词和常用标点符号 （即图中 "候 选字词" ） ， 送到候选字词显示单元也可在屏幕上显示。 The whole process works as shown in Figure 3. When a single-finger or stylus clicks or slides on the touch screen on the phone or tablet (the "touch screen hardware" in the figure), you can get a click or slide from the touch unit. Coordinate and sliding information, wherein the sliding information includes content such as finger pressing or releasing, and the touch unit may be a touch screen hardware driver or a software device such as an operating system, and the above information is filtered and filtered by the validity judging unit, and the information is obtained. Further identify and process valid screen coordinates and sliding information. Using the obtained valid information, the analysis of the keyboard partition calculation unit can determine the partition to be input and the set of letters or common punctuation marks (ie, "character groups" in the figure). The sequence validity check and the candidate word generating unit perform a complete arrangement and combination according to the partition and the letters or common punctuation marks represented by the previously input partitions to obtain a sequence of letters of equal length (that is, English words or other languages) English alphabetic coding of input methods) or commonly used punctuation marks, but since not all of these alphabetic sequences exist and are meaningful in the dictionary of an English dictionary or some other input method, they must be valid with reference to the data in the dictionary. Sexually screening, eliminating the meaningless sequence of letters, the resulting sequence of valid character combinations is the last meaningful sequence of letters or common punctuation. For English, they are English words and common punctuation, but for other languages it It is only the English alphabetic code and the commonly used punctuation marks. Of course, the corresponding words and common punctuation marks can be obtained in the process of referring to the dictionary screening. The character combination sequence is the English alphabetic code of the above-mentioned English words or common punctuation marks or some input method of other languages, and these sequences are sent to the character combination sequence prompting unit to be displayed on the screen, and the words corresponding to other language letters are also encoded. Words and common punctuation marks (ie in the picture) The word "" is selected and sent to the candidate word display unit can also be displayed on the screen.
前面仅对单指或输入笔的操作过程作了概括性描述， 具体来说， 我们可 以以图 1所示键盘分区结构为例， 将滑行情况与实现操作关系总结为表 1 内 容。  In the foregoing, only the operation process of the single finger or the input pen is generally described. Specifically, we can take the keyboard partition structure shown in FIG. 1 as an example to summarize the relationship between the sliding condition and the implementation operation as Table 1.

通过上述的单指滑行操作和键盘四角的功能按键已经可以实现文字的正 常录入， 但是对于回车 /换行、 向后删除、 向左向右移动光标等常用编辑操作， 键盘布局上并没有按键或者分区来执行它们的功能， 所以引入双指操作来实 现。 虽然目前主流触屏手机、 平板电脑等设备都具备， 但是仍然有必要说明 的是， 双指操作的实现要求设备的触摸屏硬件必须支持多点触控， 否则上述 编辑操作可以考虑通过点击菜单中功能项来实现。 表 2详细列举了双指操作 与常用编辑操作的对应情况。  The normal input of text can be realized by the above-mentioned single-finger sliding operation and the function keys of the four corners of the keyboard, but for the common editing operations such as carriage return/line feed, backward deletion, moving the cursor left to right, there is no key on the keyboard layout or Partitions perform their functions, so a two-finger operation is introduced. Although mainstream touch screen mobile phones, tablet computers and other devices are available, it is still necessary to explain that the implementation of the two-finger operation requires that the touch screen hardware of the device must support multi-touch, otherwise the above editing operation can be considered by clicking the function in the menu. Item to achieve. Table 2 details the correspondence between the two-finger operation and the common editing operations.
