在本发明所述的感应信号输入装置中，所述特征动作触发信号包括：触摸触 发信号、滑动触发信号、按压后离开触发信号与按压后松开并保持接触触发信号。
在本发明所述的感应信号输入方法中，所述的的触发信号是由输入主体控制 执行的， 如用户以手指、 手写笔等进行输入操作。
在本发明所述的感应信号输入方法中，所述的执行上述步骤为 S1-S4中的任 意步骤。
在本发明某些步骤中所述的 "第一"或 "第二" 、 "第三"和 "第四"是标 识性词汇， 并不代表前后顺序， 需在具体论述中结合实施例理解。
在本发明某些步骤中所述的 "触发信号"是指： 以某一动作作用于设备， 并 因此产生相应的信号。 如按下按键" 3 "， 根据设定， 这样的动作即触发了相应的 信号， 设备据此输入 "3 "。
在本发明中所述感应信号输入方法中， 所述的 "标记 "的含义是： 以异于其 他信号的显示方式来显示某一信号， 使之能够被识别出来。 "标记"的方式包括: 亮显、 凸显、 反白、 放大、 缩小、 闪烁、 加大对比、 变形、 变换字体、 立体显示 等一切与其他信号的显示方式明确不同且易于区别方式进行显示。
在本发明所述的感应信号输入方法中，所述的触发步骤、映射步骤、转移步 骤、判断步骤、提示步骤、 跳转步骤与回转步骤是本输入方法所包含的步骤， 本 申请中的排列顺序只代表其中一种可能， 除此之外尚存在其他可能。
在本发明所述的第四特征动作与所述的回退有异同， 详见实施例。
在本发明某些步骤中所述的显示，其含义可以是：根据具体要求全部或者部 分信号以一定秩序或一定方式显示出来。 在步骤 S4中所述 "邻接所述第一空间 节点拾取信号的信号" 即可依靠其秩序进行判断其所涉及的 "邻接"信号。 S1 及触发步骤未限定是否将此时第一空间节点对应的拾取信号标识出来，因为在输 入开始时， 第一个拾取信号无论标识与否都有可能被识别。 之后若在 S5步骤进 入循环选择时后再执行 S1时， 就须对拾取信号标识。 本申请采用了概括性的描 述， 因为这不会引起本领域技术人员的误解。
在本发明所述的感应信号输入方法中， 所述的 " S3、 将所述第一空间节点 映射信号映射到邻近所述第一空间节点的至少一个第二空间节点"， 这包含了将 第一空间节点的全部或部分 (包含一个)映射信号映射到第二空间节点的可能， 也 包含了给第二空间节点增加映射信号的可能， 这其中也可包括拾取信号， S3 未 对此限定。 映射步骤可依此理解。
在本发明所述的感应信号输入方法中， S4步骤中所述的邻近， 其含义指映 射信号在排列秩序中与空间节点拾取信号相邻、尾随、旁接或相关联的关系。所 述拾取信号包括图 2中涉及的优选字符。
在本发明所述的感应信号输入方法中，所述的转移步骤是依一定规则将第一 空间节点的某一映射信号设为第二空间节点的拾取信号， 如依据某种秩序或关 系， 包括空间秩序、 语言学关系或者显示中的位置关系等。
在本发明某些步骤中所述的 "映射信号"是指： 某一空间节点对应的信号或 信号集。 步骤 S2、 S4与 S5中所述的 "拾取信号"是指： 某一空间节点若干映 射信号中可以直接对应的输入信号， 拾取信号包含于映射信号。
在本发明所述的感应区域可以是由数个独立的感应节点、感应按键组合所形 成的区域， 如感应键盘， 也可以是一个划分出多个感应节点的触摸表面。
在本发明所述的空间节点是感应区域内至少具备感应功能的空间节点。 在本发明所述的感应信号输入方法中， 步骤中 S4及提示步骤所述的第二特 征动作触发信号的一种常见形式是： 手指或输入设备（以下简称手指）从第一空 间节点移至所述第二空间节点， 即此时第二特征动作为： 将手指或输入设备在感 应区域内由当前的空间节点移至一邻近的空间节点。 当然亦包括其他可能的情 形， 如不断增加压力以模拟类似 "按入 "的操作， 即能够表达连续选择的特征动 作通常就具备定义为第二特征动作的可能。
在本发明某些步骤中所述的 "收到输入完毕的信号"， 其含义包括输入过程 的阶段性完成或全部完成， 并不排除再输入其他信号的可能。如对某一单词的输 入完成后，可视为一次输入操作的结束，但也可以接着再输入其他单词。所述"输 入完毕的信号"可以是输入过程的自然终结，如实施例 8中的步骤九所述的选择 输入也同时可以视为一个输入操作的结束； 所述 "输入完毕的信号"也可以以 特定的输入动作作为结束标志， 如特定的回车或退出键等，。
在本发明中所述的"当判定上一目标信号输入完成后"是指已输入某一信号， 而不是指 （整个） 输入过程已经完成。
在本发明中所述的"回退"是一种在输入过程中错过目标信号时采取的修正 调整措施，例如手指至少从当前感应节点回退到前一个经过的节点，以此为转折， 屏幕的反白标识将以相对于原方向的相反方向回退，即已经放弃的拾取信号将以 反向次序再次被标识出来，直至接收到确认输入信号或再次接收到回退信号， 回 退的数量决定于经过节点的个数。
在本发明中所述的 "图形"， 其含义是手指经过节点所形成的同质图形， 这 种图形无论位于规定的感应区域任何位置都被视为同质的。如对于图 5所示的感 应键盘， 经过键位 "2、 3、 6"所形成的图形与经过键位 "4、 5、 8 "所形成的图 形是相同的， 对应于同样的信号。所述的"轨迹"是针对触摸屏或触摸板这样没 有明显凸凹纹理的感应设备而设定的，通过对不同轨迹的归纳分析判断对应的信 号， 这样就不必拘泥于感应节点的约束。
在本发明所述的感应信号输入装置中，所述感应键盘上的键位彼此相邻且为 规则排列， 如附图 5、 6、 7所示。
在本发明的各个实施例中， 所述第一~第五特征动作彼此不相同。 所述特征 可以是动作特征、 速度特征、 数字特征、 压力特征、 温度特征和 /或几何特征。 在本发明中优选动作特征。 所述动作特征可以包括触摸、 按下、 长按、 停留、 离 开、移动、悬空触摸、双击、 回搓、 回位、按压后离开、按压后松开并保持接触、 同时触及两个（数个）键位以及各种划线动作等中的至少一种或多种。 为方便描 述，针对具有不同的操作区域、不同界面或不同对象的同一动作也可定义为不同 的特征动作，如作用于按键区域与作用与于选择区域的按压就可以定义为不同的 特征动作。
在本发明的另一实施例中，所述感应区域可以是触摸屏，对于带有触摸屏的 电子设备， 可直接选取各种目标信号。采用无压感或回馈的触摸屏时， 因其仅能 识别简单的触摸信号， 与能够接受按压信号的感应键盘相比， 能接受的特征动作 的种类与操作均受到限制，如感应式键盘能在手指滑过感应节点后， 以手指离开 键盘的方式输入信号 (如逗号)； 也可在手指滑过感应节点后， 以按压当前键位的 方式输入对应的信号； 而触摸屏不能接受按压信号， 因而难以区别上述操作， 当 然也可以停滞时间的长短进行区别，但不方便。当触摸屏能感知按压信号或产生 回馈时， 其操作性与感应键盘相近。
当触摸屏或感应键盘能够接受多点触摸信号时，其可以以多点触摸与单点触 摸之间的组合产生多种特征动作，甚至部分替代感应键盘的按压操作，这是非常 容易理解与想象的， 这里不再叙述。
在本发明的另一实施例中，所述的显示区域与感应区域可以位于同一平面或 同一切面， 也可以位于不同的平面。如手表式数字设备， 显示区域和感应区域同 位于表盘正面， 采用本发明后， 可以将感应区域设置于表盘背面， 充分利用表盘 正面的面积， 增大可视面积， 操作方便。 本发明使得各种语言如英语、德语等可在同一输入设备上切换，而不必更换 不同的键盘， 这是本领域技术人员非常容易理解与想象的， 这里不再叙述。
实施本发明的感应信号输入装置和方法， 不但采用连续的人性化的输入方 式， 不必记忆输入码， 摆脱了键位符号的束缚， 易于实现 "盲打"， 单手操作， 自然***手写标点符号输入，还能够根据用户输入灵活调节感应区域内各个节点 的对应的信号内容， 从而简化输入过程。 附图说明
下面将结合附图及实施例对本发明作进一步说明， 附图中：
图 1是本发明感应信号输入方法的第一实施例的典型步骤的流程图； 图 2是本发明感应信号输入方法的第二实施例的典型步骤的流程图； 图 3是本发明感应信号输入装置的第一实施例的原理框图；
图 4是本发明感应信号输入装置的第二实施例的原理框图；
图 5是使用本发明的感应信号输入装置输入字符的示意图；

如图 1示出了本发明的感应信号输入方法的第一实施例中的典型流程： 在步骤 S1中， 感应区域的第一空间节点接收第一特征动作触发信号并在显 示区域上显示映射到所述第一空间节点的第一空间节点映射信号，所述第一空间 节点映射信号包括至少一个第一空间节点拾取信号。
在本发明的优选实施例中，所述感应区域是感应键盘，所述空间节点是感应 键位。所述的感应键盘能够区别并接受至少一种特征动作， 能够感知并区别输入 设备（如手指）在各键位之间的移动与点击。 在本发明的另一实施例中， 所述感 应区域是触摸屏， 包括相应的虚拟键盘和显示区域。
在本发明的一个优选实施例中，所述第一特征动作是，手指或输入模块触摸 感应键位。 在此， 触摸可以指长时间（滞留）触摸、 悬空触摸或者接触并按下触 摸键位。
在步骤 S2中， 如果所述第一空间节点拾取信号是目标信号， 则以第三特征 动作触发信号输入所述第一空间节点拾取信号， 并执行步骤 S3， 否则直接执行 步骤 S3。
在本发明的一个实施例中，所述第三特征动作触发信号可以是轻敲感应键位 进行输入。在此， 也可定义其他的动作， 本发明并不受各个特征动作的具体定义 的限制。
在步骤 S3中， 将所述第一空间节点映射信号映射到邻近所述第一空间节点 的至少一个第二空间节点。在本发明的优选实施例中，可将所述第一空间节点周 围所有的空间节点定义成第二空间节点，将所述第一空间节点映射信号映射所述 多个第二空间节点。在本发明的其他实施例中， 也可只定义邻近所述第一空间节 点的部分空间节点为第二空间节点。本发明不受到第二空间节点的个数和位置的 限制。
在步骤 S4中， 接收到触发第一空间节点和所述第二空间节点的第二特征动 作触发信号时，在显示区域上显示所述第一空间节点映射信号， 并标记所述第一 空间节点映射信号中邻接所述第一空间节点拾取信号的信号为第二空间节点拾 取信号。在本发明的一个实施例中，第二特征动作可以是从第一空间节点滑动到 第二空间节点。
在步骤 S5中， 如果所述第二空间节点拾取信号是目标信号， 则以第三特征 动作触发信号输入所述第二空间节点拾取信号， 并循环执行 S1-S4, 否则直接循 环执行步骤 S1-S4, 直至接收到目标信号输入完毕信号。 该目标信号输入完毕信 号可以是手指离开感应区域， 也可以是其他特征动作。
需要说明的是， 当在步骤 S1-S5中， 接收到目标信号输入完毕信号时， 直接 退出本次输入操作。该目标信号输入完毕信号可以是手指离开感应区域，也可以 是其他特征动作。
在本发明的各个实施例中，所述第四特征动作在实施例 4中体现为 "回搓"， 系指触及第一键位后移动到另一相邻键位后，又移回第一键位；其结束动作可以 是（回到第一键位后）离开键位， 也可以是（回到第一键位后） 点击、 长按或双 击键位， 但不得与其他输入动作发生冲突。其中回搓动作又可进一步包括： 水平 回搓、 垂直回搓、 斜向回搓等。 "移动"指手指从一个键位移至一个相邻键位， 与手指相续触及相邻的两个键位的区别在于：手指不离开键盘或触及两个键位的 时间间隔短于触及一个键位再触及另一个键位的时间间隔。
本发明所述的 "输入所经过的感应节点形成的图形或轨迹所对应的信号"， 亦即实施例 13中混合输入 "和平"与逗号 " ，的实例， 内容是手指在感应键盘 表面连续触及的键位连成的线条符合约定的图形，以此为依据对应某一特定的信 号， 如连续触及键位 " 2、 1、 4、 5 "， 形成 "C"形图案， 表示 "复制"等。 此 处由于其与具体的符号对应而未归入特征动作。
在本发明的各个实施例中， 所述的信号包括： 字符、 字符串、 汉字、各种字 母、单词、词组、成语、指令、各种固定的字母组合（前缀、后缀、复合韵母等）。
在本发明的各个实施例中，关联包括几何关联与语言关联。几何关联指以映 射信号在空间中的排列次序为依据的关联， 如图 5所示的键盘中， 与 " K"相关 联的信号即与之相邻的信号， 如 "J、 L"， 也可以包括 "G、 H、 I、 M、 N"等。
语言关联是指语言学原理为依据的关联，据此可判断与已输入信号能够形成 组合的信号， 这样的组合包括单词、拼音、缩写、前缀、后缀、表情符号、成语、 词组等， 如可与 "K"组成单词的信号为： A、 E、 I、 N、 0、 R、 U， 其他的不 可能邻接在信号 "K"之后并与之组成单词， 因此其他信号可视为与 "K"无关 联或关联较弱， 这样在实际案例中 "A、 E、 I、 N、 0、 R、 U"等有关联的信号 可排在前部，其他的无关联或关联性较弱的也可排列于后部。字母表的排列顺序 也可视为一种语言关联。
关联程度高低"包括： 1、 信号在行文用语中出现概率的高低； 2、 用户使用 频率的高低； 3、 商业（广告）价值的高低； 4、 互联网用户使用频率的高低； 5、 机器根据上下文智能判断各信号出现概率的高低。
图 2是本发明感应信号输入方法的第二实施例的典型步骤的流程图。如图 2 所示， 在步骤 S1中， 首先将字符映射到数个键位上。在本发明的一个实施例中， 可以是全部键位， 也可以是部分键位。在此所述字符可以是一个或多个字母、数 字、 汉字或其组合。 在步骤 S2中， 手指触摸某一键位 （第一键位）。 在步骤 S3 中， 屏幕显示该键位对应的字符集合， 将最优选的字符亮显。在本发明的各个实 施例中， 所述最优选字符可以是一个或多个。 接着在步骤 S4中， 相邻键位与字 符的对应关系发生改变，相邻键位的优选字符依规则定为异于本键位优选字符的 字符。 在步骤 S5中， 判定第一键位的亮显优选字符是否为目标字符。 如果是执 行步骤 S10， 按下当前键位， 确认输入该字符。 在本发明的另一实施例中， 也可 以是手指离开当前键位， 确认输入该字符。在本发明的其他实施例中， 也可采用 其他特征动作进行输入。 在本发明的优选实施例中， 进入步骤 Sll， 屏幕显示出 与该字符相关的字符，如与输入字符在字母表中的位置或形状相关，或者是可以 输入组成英文单词或汉语拼音的字符。在本发明的简化实施例中， 也可不执行该 步骤。在本发明的另一优选实施例中， 如中文输入模式中， 可根据已经输入的内 容显示可能的汉字或单词的二级提示。该二级提示可以通过合适的特征动作加以 选取， 或者通过键盘上的特定键位的触发加以选取。
如果在步骤 S5中， 判定不是目标字符， 则执行步骤 S6， 手指按照规则一定 到相邻的键位。 在步骤 S7中， 判定手指是否回到手指刚刚经过的相邻键位， 如 果是则进入回退模式， 执行步骤 S13， 否则执行步骤 S8。 在步骤 S8中， 屏幕亮 显该键位对应的字符（即， 对应关系已经发生了改变的）， 接着执行步骤 S9。 在 步骤 S9中， 当前的键位的相邻键位的对应关系再次发生如上改变。 即相邻键位 的优选字符为排列于当前亮显字符之后的字符， 随后返回步骤 S5， 判断当前亮 显字符是不是目标字符。
如果判定进入回退模式， 则执行步骤 S13， 显示屏上的提示字符的亮显顺序 改为反向， 则此时手指每反向移动一个键位， 亮显字符反向回退一次。 随后执行 步骤 S14， 依照手指的移动亮显相应的字符。
在本发明的另一优选实施例中， 还进一步包括： 当在步骤 S10 中， 确认输 入第一个字符后， 可将与之匹配的字符或字符串过滤出来， 排列在显示屏中， 亮 显最优选项， 操作者可根据需要判断选定目标选项。在该优选实施例中， 所述字 符可包括单个字符或字符串， 如前缀、 后缀、 词根、 符合韵母等。
在本发明的汉字输入的另一优选实施例中，当最后一个目标拼音字符亮显以 后， 手指按下当前位置的键位， 确认输入。 此时显示屏上显示匹配的文字， 并亮 显优选文字。 操作者可通过滚动或判断选定目标文字。
在本发明的另一优选实施例中，当输入第一个拼音字符之后，显示屏已输入 信息除了给出后续的输入选项， 也在另一区域给出若干匹配的汉字 (即所述的二 级选项）并加以标识。 此时， 若操作者的手指离开当前所在的键位， 表示显示屏 显示的汉字存在目标字符。此时操作者可直接按下目标汉字对应标识所指示的键 位 （如果是触摸屏， 可直接点去该键位）， 以确认输入该汉字。
在本发明的另一优选实施例中，当输入第一个拼音字符之后，显示屏根据输 入信息除了给出预测的最优选项 (即所述的二级选项）。 手指离开当前所在的键 位，并保持一段时间，直至确认将最优字符作为目标字符输入并显示于正文区（正 文区即指显示已输入文档的区域）。 在本发明的另一实施例中， 可以直接选取。 接着操作者直接按下目标汉字对应标识所指示的键位（如果是触摸屏，可直接点 去该键位）， 以确认输入该汉字。
在本发明的各个实施例中，键位排列适用的形式多种多样，可采用普通手机 的键盘形式如图 5， 也可采用 Qwerty键盘、 环形键盘等布局方式， 还可以运用 于基于触摸屏的虚拟键盘，甚至键位可以由用户自由定义。键位的排列也比较自 由， 可以是规则排列， 规则排列的变形或者自由排列。 规则排列如： 矩阵排列、 环形排列、 蜂窝型排列、 菱形排列放射状排列与线性排列等等。
通常， 一个感应键位只有一个感应点，对应于相应的映射信号与至少一个拾 取信号。但是可以扩展为， 一个感应键位上拥有数个不同的感应点， 这些感应点 在空间上不重叠， 处于不同的平面坐标点（区域）上， 并可以被识别， 每一个感 应点对应于相应的映射信号与至少一个拾取信号。这些感应点接受的 "按下 "（点 击） 信号均为该键位接受的 "按下"（点击） 信号。
感应按键尤其是（触摸屏）虚拟按键的定义可以具备相当大的灵活性， 比如 在某种状况下可以是感应节点与信号一一对应，但在使用过程中也可以根据设定 改变为数个感应节点对应于一个信号，本输入方法和设备可以与之相适应， 利用 键位的合并或分割来适应输入要求。
图 3是本发明感应信号输入装置的第一实施例的原理框图。如图 3所示，本 发明的感应信号输入装置包括感应区域 100; 位于所述感应区域内的多个空间节 点 101-lOn; 用于将信号映射到所述多个空间节点中的每一个以作为初始空间节 点映射信号的映射模块 200; 信号显示模块 300， 用于在接收到用户触发第一空 间节点的第一特征动作触发信号时，在显示区域上显示映射到所述第一空间节点 的一个或多个信号，并标记所述第一空间节点对应的至少一个第一空间节点拾取 信号； 映射调整模块 400， 用于在接收到用户触发第一空间节点的第一特征动作 触发信号时， 调整邻近所述第一空间节点的至少一个第二空间节点的映射关系， 将所述多个信号映射到所述第二空间节点； 第一感应显示模块 500， 用于在接收 到用户触发第一空间节点和所述第二空间节点的第二特征动作触发信号时，在显 示区域上显示所述映射到所述第二空间节点的多个信号，并标记邻近所述第一空 间节点映射信号的至少一个信号为所述第二空间节点的拾取信号；信号拾取模块 600， 用于在接收到用户触发某一空间节点的第三特征动作触发信号时， 选取所 述空间节点对应的信号并完成信号的输入。本发明的各个模块可以单独实现，也 可以组合实现。
在本发明的优选实施例中，所述感应区域是能够区别感知并接受不同输入特 征动作同时能够区感知并区别各个键位之间的移动与点击的键盘。在本发明所述 的感应信号输入装置中，所述感应区域上的至少存在两个空间节点相互邻接。在 本发明的又一优选实施例中，所述感应键盘上的键位呈矩阵排列。在本发明的又 一优选实施例中，所述感应键盘上的键位排列成圆环状。在本发明的其他优选实 施例中， 感应键盘上的键位还可排列成矩形、 正方形或者任何其他合适的形状。 在本发明另一实施例中，所述感应区域可以是触摸屏，可直接选取各种目标信号。 图 4是本发明感应信号输入装置的第二实施例的原理框图。如图 4所示，本 发明的感应信号输入装置除包括图 3 示出的模块以外， 还进一步包括回退模块 700， 用于在发生操作错误时或者需要调整时， 采用第四特征动作触发信号将操 作退回到前一状态。所述前一状态包括显示区域显示前一空间节点的空间节点拾 取信号和 /或取消当前输入； 中文判断模块 800，用于根据输入信号产生对应所述 输入信号的一个和 /或多个中文符号， 并接收第五特征动作触发信号以选定所需 中文符号。本发明的这两个模块可以单独实现， 也可以组合实现， 还可与图 3中 示出的一个或多个模块相互组合实现。
在本发明的简化实施例中，所述装置进一步包括第一输入判断模块，用于当 判定上一目标信号输入完成以后，将所述各个空间节点所对应的空间节点映射信 号复位到初始空间节点映射信号。在本发明的优选实施例中，所述装置进一步包 括第二输入判断模块，用于当判定上一目标信号输入完成以后，在显示区域上显 示与所述上一目标信号关联的一个或多个信号，并标记关联程度最高的信号为当 前空间节点对应的空间节点拾取信号。 上述第一和第二输入判断模块可参照图 2 中给出的具体流程加以是实现。本领域技术人员在本发明的教导下， 能够搭建上 述各个模块并实现其功能。
图 5是使用本发明的感应信号输入装置输入字符的示意图。如图 5所示，手 指触及感应键位" 5"， 显示屏 41的相应区域显示" J、 K、 L、 M、 N、 O"等字符， 其中 T反白。 此时键盘内字符的对应关系发生改变： 与" 5"键相邻的所有或部分 键位其对应的优选字符均变为 "Κ"， 也就是说， 当手指移动到键位 2时， 显示屏 41的相应区域显示" J、 K、 L、 M、 N、 O"等字符， 其中" K"反白。 在本发明的其 他实施例中， 当手指移动到键位 2时， 显示屏上也可显示其他字符， 但这些字符 中应该包括 "Κ"， 且 "Κ"反白。
下面以具体实施例的方式，对本发明的原理作进一步的说明。本领域技术人 员知悉，下述实施只是用于说明而不是用于限定本发明， 下面的实施例如未加说 明均以图 5所示的感应键盘为例。 实施例 1 : 以简单规则输入单词 "KEY"
步骤一， 手指（即所述手指与输入设备）触及（即第一特征动作）感应键位 "5 "， 显示屏相应区域显示 "J、 K、 L、 M、 N、 O"等字符， 其中 "J"反白， 表明此时手指按下 （或离开） （即第三特征动作） 键位 "5 " 即可输入字符 "J"; 步骤二， 键盘内字符的对应关系发生改变： 与 " 5 "键相邻的所有（或部分） 键位所对应的字符均变为 "K"。
步骤三， 由于反白的 " J "不是目标字符， 手指由键位 "5 "移动至（即第二 特征动作）键位 "6"， 此时相应区域显示的 " J、 K、 L、 M、 N、 O"等字符， 其 中反白字符由 " J "变成 "K"， 此时周边的键位与字符的对应关系再次改变 （类 似步骤二）， "Κ"是需要的目标字符， 手指按下 （或离开） 键位 "6" 即可输入 字符 "Κ";
步骤四， 同理输入 "Ε"与 "Υ"， 完成输入。
注： 将 "离开"作为确认输入的特征动作， 即手指一旦从某一键 （a) 位离 开感应设备就已完成这一特征动作， 而由某一键位（a)前往另一键位（b )虽然 也离开了键位 （a)， 但由于没有脱离与感应区域的接触， 故归入其他特征动作。 当然 "离开"也可以分很多种， 如 "侧滑离开"、 "旋转离开"等， 这些因难以操 作或识别， 因而极少应用， 这里也不详细描述。
"按下 "是常见的按键输入动作，在非触摸按键中，通常确定最终的"按下" 输入动作后， 无论手指离开键盘与否， 即表明地确认了输入信号。但对于具备感 应功能的按键来说， "按下"（或 "按下后后松开并保持接触"）与 "按下后离开" 依设定会具备不同的特点： 如 "按下"后不离开， 可能表明确认输入后进入后续 选择； "按下后离开"则表明确认输入后进入下一输入阶段。 具备按压、 回馈功 能的触摸设备的操作性要远强于只能触摸感应的触摸设备。 实施例 2: 输入单词 "KEY"
步骤一， 手指接触到键位 "4"， 显示屏显示 "G、 Η、 。
步骤二， "G、 H、 I" 中没有目标信号， 手指移动到键位 " 5 "， 此时显示屏 显示另一组信号 " J、 K、 L"。
步骤三， " J、 K、 L" 中有目标信号 "K"， 按下键位 "5 "， 触发起始输入键 位 "5 "。
步骤四， 此时屏幕显示 " J、 K、 L、 M、 N、 0、 P"， 其中 " J "被亮显， 位 置优选的输入信号 （此时按下按键将输入 " J")。
步骤五， 手指移动到一个临近键位如 "6"， 其中 "K"被亮显。
步骤六， 按下当前键位如 "6"， 输入字符 "K"
步骤七， 输入其他字符。
注：该实施例在对应的步骤 S1与 S2之间增加了一个按压确认动作，用于确 认起始键位， 某种情况下可以简化操作。在步骤三中按压确认动作执行后， 不仅 可以选取与该键位对应的字符， 也可以选取其他字符。 实施例 3: 以智能模式输入单词 "KEY"
步骤一至步骤三同实施例 1的步骤一至步骤三。
步骤四， 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏相应显 示区域提示为 "1、 0、 E、 A、 N、 R、 U、 B、 C、 D、 F"等与 "K"相关联的字 符，其排列顺序的依据是由与字符" K"的关联程度高低而设定排列的，字符" I" 被反白， 表明若此时再次按下键位 "6"将输入字符 "1"。
步骤五， 由于 " I"不是目标字符， 继续移动手指至键位 "9"， 相应显示区 域中的字符 " 0 "被反白， "0"亦不是目标字符； 继续移动手指至键位 " 8 "， 此时 "Ε"被反白， 为需要的目标字符； 手指按下（或离开）键位 "8 "即可输入 字符 "Ε";
步骤六， 此时手指仍然在键位 " 8"上， 显示屏相应显示区域提示为 "Ε、 Υ、 Ν、 Ρ、 Τ、 G"等与已输入的 "ke"相关联的字符， 按优先顺序排列， 字符 "E" 反白， 该字符不是目标字符， 手指继续移动至 " 7 "， 反白字符变为 "Y"， 手指 按下 （或离开） 键位 "7"即可输入字符 "Υ"， 单词 "KEY"输入完成。
注： 其中步骤四也可以有以下两种可能：
第一种可能是： 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏 相应显示区域提示为 "K、 I、 0、 E、 A、 N、 R、 U、 B、 C"等与 "K"相关联 的字符， 其排列顺序的依据是由与字符 "K"的关联程度高低而设定排列的， 字 符 "K"被反白， 表明若此时再次按下键位 "6"将输入字符 "K"。
第二种可能是： 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏 相应显示区域提示为 "Κ、 I、 0、 E、 A、 N、 R、 U、 B、 C"等与 "K"相关联 的字符，其排列顺序的依据是由与字符" K"的关联程度高低而设定的，字符" I" 被反白， 表明若此时再次按下键位 " 6"将输入 " ; 若此时手指回退至前一经 过键位即 "5 "， 字符 "Κ"即被反白， 按下该按键， 则再次输入字符 "Κ"。
上述操作由程序设定， 附注中两种可能的设定是为方便重复输入字符。 实施例 4: 输入单词 " KEY", 且在输入过程中纠正笔误
步骤一至步骤三同实施例 1的步骤一至步骤三。
步骤四， 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏相应显 示区域提示为 "1、 0、 E、 A、 N、 R、 U、 B、 C、 D、 F"等与 "K"相关联的字 符，其排列顺序的依据是由与字符" K"的关联程度高低而设定排列的，字符" I" 被反白， 表明若此时按下键位将输入字符 " 1"。
步骤五， 由于 "I "不是目标字符， 继续移动手指至键位 "9"， 相应显示区域中 的字符 " 0 "被反白， 此时用户发生一个操作错误， 手指按下 （或离开）键位" 9"， 即错误地输入了字符 "0";
步骤六， 此时做出一个连续在两个相邻的不同键位之间往返移动的 "回搓" 动作， 表明操作退回前一状态或取消前一操作， 如先接触键位 "5 "， 然后移至相 邻的键位 "6"， 接着再移回键位 "5 "， 此时设备取消输入的字符 "0"， 显示屏 相应显示区域提示为 "1、 0、 E、 A、 N、 R、 U、 B、 C、 D、 F"等与 "K"相关 联的字符， 其中 "0"被反白。
步骤七， 由于 "0"不是目标字符， 手指由键位 "5 "移动至键位 "6" (或 "2、 8、 4" 以及 " 1、 3、 7、 9")， 提示区显示的字符为 "1、 0、 E、 A、 N、 R、 U、 B、 C、 D、 F"等， 其中 "E"被反白。
步骤八， 手指按下 （或离开） 键位 "6"， 确认输入字符 "E"。
步骤九， 类似输入字符 "Y"
注： "回搓"一般于两个相邻的键位之间操作， 也可以设为 "进 2退 1 "、 "进 1退 2"、 "进 1退 2"、 "进 N退 M"等， 可根据需要设定为 "回到前一个输入状 态"或者 "取消刚才输入的字符"。 一种设定是步骤六时手指离开键盘后执行的 特征动作， 当步骤六执行完"回搓"动作后， 手指可以离开键盘， 也可停留在当 前的键位依屏幕提示操作。 前者 "回搓"可在任意两个相邻的感应按键上执行， 该操作之后的键位与信号的对应关系可以另行设定或根据已输入信息进行设定。 后一种设定可以是步骤六时，手指不离开键盘，在键位 "7"与" 8"之间进行"回 搓"， 取消字符 "0"， 之后直接进行输入。
后一种的 "回搓"动作一般需在确认输入某一字符后立即进行， 否则将可能 与 "回退"动作混淆。 实施例 5: 快捷方式输入单词 " KEY"
步骤一至步骤三同实施例 1的步骤一至步骤三。
步骤四， 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏相应显 示区域提示为 " K、 0、 I、 E、 N、 U、 A"等与" K"相关联的字符， 其排列顺序的 依据是由与字符" Κ"的关联程度高低而设定排列的， 字符 " Κ "被反白， 表明若 此时按下键位将输入字符 " K "; 同时正文区当前输入位置或其他显示区域出现 输入单词 "KEY" 的提示， 表明该单词为可以缺省输入的单词。
步骤五， 通过特定的输入动作完成对缺省单词 "KEY"的确认输入， 如手指 直接离开当前键位， 表明确认输入单词 "KEY"， 或者手指离开当前键位后再按 下特定的功能键位 （或直接触摸显示单词 "KEY" 的区域）， 确认输入。
注： 该实施例中的缺省输入单词可以在出现在每一次输入字符之后，供用户 进行选取。 此实施例可与触摸屏配合共同实现。
实施例 6: 输入单词 "KEY"过程中由于滑动过快需回退至上一字符。
步骤一至步骤三同实施例 1的步骤一至步骤三。
步骤四， 当键位弹起后， 保持手指对感应键位 "6" 的触摸， 显示屏相应显 示区域提示为 "1、 0、 E、 A、 N、 R、 U、 B、 C、 D、 F"等与 "K"相关联的字 符，其排列顺序的依据是由与字符" K"的关联程度高低而设定排列的，字符" I" 被反白， 表明若此时按下键位将输入字符 " 1"。
步骤五， 由于 " I"不是目标字符， 继续移动手指至键位 "9"， 相应显示区 域中的字符 " 0 "被反白， "0"亦不是目标字符； 继续移动手指至键位 " 8 "， 此时 " Ε"被反白， 为需要的目标字符， 但是由于手指移动过快， 多移动了一个 键位至键位 " 7"， 此时字符" Α"反白。
步骤六， 因" Α"不是目标字符， 且错过了目标字符 "E"， 手指由键位" 7"移回 键位" 8"， 字符 "E"重新反白， 手指按下 （或离开） 该键位， 确认输入字符 "E"。
注： 在步骤六中， 若手指移动到键位" 8"后， 继续向与" 8"相邻的除键位 "7" 以外的任一键位移动， 如键位 "5、 9、 0"等， 则表明继续回退反白至前一个经 过的字符， 本例中为 "0"。 也就是说， 在输入过程中， 当手指移向未经由的相邻 键位时， 反白依照当前顺序向前进行； 当手指移过曾经经由的与之相邻键位， 表 明将当前反白的顺序改变为相反的顺序。
由当前键位回退至上一个操作状态所在的键位，其对应的信号也可以仅仅表 示装置进入回退状态， 而但需要手指继续移动到下一个键位 （除当前键位外）， 显示区域的显示才改变为之前的状态。
上述实施例所述的回退动作关键在于： 手指移回最近触及的键位。在此基础 上可以增减动作要素， 比如按压、 多点、 回移数键位等。 "回退"状态保持至下 一个回退动作产生或者确认输入字符为止，如本例在步骤六输入 "E"后所述 "回 退"状态也随之结束。 当然也可以另行设定回退动作， 比如单指移动过程中加入 另一手指继续移动， 则表明进行回退选择。 有时对于某些触摸屏（板）设备而言， 上述表示回退的第四特征动作可以通 过手指移动与当前前进方向、水平或垂直或形成的角度进行判断， 当该角度大于 (或小于） 一定值时， 便定为回退即 "第四特征动作"。 上述方法可为适应缺乏 手感的触摸屏 （板） 而专门设定。
除手指移回最近触及的键位之外， 还有其他"第四特征动作"可供选择， 如 斜向移动， 若本实施例步骤六中， 手指由键位 " 7"移至键位 " 5 "后， 便产生回 退， 此时字符 "E"便重新反白， 即可确认输入该字符， 之后的操作可参照相关论 述。 所述斜向移动指手指通过的感应节点中心的连线不是水平或垂直方向。 实施例 7: 以过滤方式输入词"和平"
步骤一， 依本申请所述的方法输入字符 "h";
步骤二，当键位弹起后，保持手指对感应键位的触摸，显示屏相应提示为" a、 e、 u、 o"等可与 "H"构成拼音组合的字符，其排列顺序依统计概率或设备的设定， 其中字符" A"被反白（此时若按下键位" 5"， 则表示输入" A") ; 同时键盘的对应关 系也发生变化， 根据设定除键位" 4"以外的与" 5"相邻键位所对应的字符均为 " (键位 "4"可与其他特殊功能相对应）。 步骤三， 由于" A"不是目标字符， 手指移 动至" 6" (或 8、 2等）， 此时字符 "被反白， "为目标字符， 按下键位" 6"， 表 明输入该字符；
步骤四，此时已输入的拼音为 "he",即是所需的拼音，手指离开感应键位（或 再次按下）， 表明拼音输入阶段完成， 进入选字阶段， 屏幕提示区内显示与 "he" 对应的字， 并以***数字加以标识， 如" 1合、 2和、 3喝、 4何、 5核、 6河、 7贺、 8呵、 9禾"；
步骤五， 手指离开键盘后， 再按下键位" 2"， 表明输入文字"和"；
步骤六， 以类似的方式输入"平"； 在本发明的另一实施例中， 当步骤四手指 离开键盘表明拼音输入阶段完成之后， 手指亦可再次触摸感应键位，或保持于当 前键位进而确保输入的连续性。屏幕将该感应键位对应的汉字标识出来， 随着手 指的移动标识不同的备选汉字。
本实施例的步骤二所述的 "显示区域相应提示为 'A、 E、 U、 I、 O ' 等" 可以改为： 显示区域相应提示为 'a、 e、 u、 o、 en、 an、 ei、 eng、 ong' 等"。 这是根据可与 "h"相组合的各种韵母而筛选排列的。
也可以将图 5所示键盘中的 " 1、 2、 3、 6、 9、 8、 7、 4"虚拟视为一个环形 转盘， 用于选择不同的文字。 当手指沿该虚拟环形转盘转动完整一圈之后， 或者 当手指经由的键位的个数超出屏幕中备选文字的数量时，设备给出另外的异于当 前所显示的备选文字供用户标识选取。 实施例 8: 以联想方式输入词"和平"
步骤一至五， 同实施例 7步骤一至五。
步骤六， 手指在步骤五停留的位置保持该键位 （"2") 的接触， 屏幕提示可 与"和"组成词组的文字， 如"谐、 好、 睦、 平、 气、 室、 风、 解、 美"等字， 其中 "谐"字作为当前位置对应的输入信号被反白。
步骤七， 由于"谐"不是目标字符， 于感应按键之间顺序滑动手指， 反白字符 依次改变， 直至"平"反白后， 按下手指所在的键位， 以确认输入"平"字。
注： 步骤六中也可备选字给予标记， 如将"谐、 好、 睦、 平、 气、 室、 风、 解、 美"改为" 1谐、 2好、 3睦、 4平、 5气、 6室、 7风、 8解、 9美"， 用户除采 用滑动的方式选字， 也可采用实施例 7中的按压相应键位的方式选字。 实施例 9: 基于时针顺序的方向控制
如附图 5， 设定以键位 "5 "为中心， 一切移动以此为中心进行判断， 确定 手指移动的时针方向， 以此判断亮显信号滚动的方向。
在这一规则下， 位于中心的键位， 其判断原则是： 向右或 /和向下移动可令 亮显信号向 "前"滚动， 即与顺时针方向移动的效果相同， 反之则相反。
本例的目标字符是 "0"
步骤一， 手指触摸键位 "6"， 此时屏幕于相应部位显示备选信号： "J、 K、 L、 M、 N、 0、 P、 Q"， 其中 "M"被亮显。
此时依据时针关系设定， 键位 "3 "对应于信号 "L"， 而键位 "9"对应于信 号 "N"， 键位 "5 "可根据需要另行规定其对应的对象。
步骤二， 手指移动至键位 "9"， 设备根据键位 "6"、 "9"与键位 "5 "形成 的夹角， 判断手指顺时针移动了一个单位， 于是将 "N"亮显。 （若此时手指移 动到键位" 3 "， 则表明手指逆时针移动了一个单位， "L"被亮显）。此时键位" 8" 与 "#" (也可以包括键位 "0") 对应字符 "0"。
步骤三， 手指移动到键位 "8"， 字符 "0"被亮显。
步骤四， 由于误操作， 手指在没有拾取" 0"的情况下移动到键位 "7"， "P" 被亮显。 此时键位 " 8 " (也可以包括键位 "0" 与 " * ") 对应的是信号 "0"， 键位 "4"对应的是信号 "Q"。 步骤五， 手指移至键位 "8"， "0"被亮显， 选取输入 "0"。
注： 本实施例针对图 5所示的数字键盘需要对键位 "5"进行单独设定， 即 当由起始键位 "5"移至相邻键位 "2、 4、 8、 6" 即为前进方向， 之后再依上述 的时针方向进行判断； 除此之外， 还可以规定起始键位为 "5"时， "右前左退" 或者 "下前上退"， "右前左退" 即由键位 " 5"移至键位 " 6"为前进方向， 由键位 "5"移至键位 "4"为后退方向， 类推 "下前上退"。 上述定义的方向可 以相互颠倒。
对于采用封闭线形布局的键盘操作判断比较容易，与规定前进方向相反的方 向即回退方向。 图 7所示的环形键盘就是这种键盘。 实施例 10: QWERT键盘输入
QWERT键盘是电子设备常用的键盘之一， 其优点是每一个按键对应一个字 母信号， 本方法也适用于该类型其他键盘。
如输入 "KEY"时， 当手指触及按键 "K"时， 屏幕显示此时对应的信号为 "H、 I、 J、 K、 L、 ；"等信号 （也可以是唯一的信号 "K")， 其中 "Κ"被反白， 表示为该按键对应的输入信号， 按下即可输入 "Κ"。 若此时按下后手指依然保 持对该按键的触摸， 则屏幕显示与 "Κ"关联的字符， 如 "Κ、 Ε、 0、 Α、 I"等， 其中 "K"反白。 由于 "Κ"不是目标信号， 手指移动的一个邻近的键位， 信号 "Ε"反白， 为目标信号， 按下按键选取该信号。
如果一开始触及的是按键 "J"， 屏幕显示此时对应的信号为 "J、 H、 J、 K、 L"， "J"被反白标识， 由于" J"不是目标信号， 手指右移到" K"按键， 此时" K" 被反白， 按下按键选取该目标信号。 实施例 11: 非封闭的线型布局键盘的操作规则
对基于线形布局的键盘（如附图 6所示）来讲， 可以在键盘的端头设置 "回 转点"， 当手指在选取目标的过程中移动到键盘的尽端的 "回转点"时， 手指反 向移动， 从而使反白信号继续正向滚动。
如假当前以设向下移动为正向滚动， 等待输入的目标信号为 "Z"， 手指触摸 感应按键" 9"， 屏幕显示备选信号： "W、 X、 Y、 Ζ"，其中 "W"反白。 由于" W" 不是目标信号， 移动手指到按键 "0"， 此时 "X"被反白。 "X"也不是目标信号， 而此时除了 "回转点"夕卜， 下方没有感应按键， 因此设定一个 "回转点"， 并约 定手指移动到该点再移回按键 "9"表明反白信号将继续正向滚动， "Y"被反白， 再次移动手指至按键 " 8"， 此时目标信号 "Z"被反白， 按下按键 " 8"， 拾取输 入该信号。回转点可以不对应任何映射信号，只表明经过该点可是反白信号将继 续正向滚动，也可以使其本身作为一个对应映射信号的感应按键，如对应于" 0"、 "#"或 " *"之类独立的信号。
注：从广义上讲，通过"回转点 "的操作也可以归纳成为一个新的特征动作， 即非封闭的线型布局键盘的尽端，可以以某一特殊的特征动作使得当前反白的滚 动方向在手指反向移动时一样得以保持。
实施例 12: 取消 （擦除） 操作与回退操作的异同
在实际应用中为避免设定过多的特征动作造成用户的困惑，常倾向于设定精 简直观的特征动作， 因而部分类似指令所对应的操作就可能较为相似，如本案所 涉及的实施例 4与 6中取消与回退通常对应的操作。这两个实施例都包含了手指 在相邻两个感应键位之间来回滑动的操作，但是由于所处的状态不同而产生不同 的信号。
本实施例中 4的取消 (擦除)操作是一个相对独立的操作， 其过程如下 步骤一， 该操作开始状态是： 上一输入信号确认输入后， 即相对应的输入特 征动作完成后 （包括第三与第五特征动作）；
步骤二， 当手指（或输入设备， 下同）触及感应区域后， 此时根据触发的感 应节点（A)， 屏幕显示对应的信号和 /或信号集合， 也可以标记其中的拾取信号； 步骤三， 当手指移动到相邻节点（B ) 时， 屏幕显示此时对应的信号和 /或信 号集合， 并标记拾取信号；
步骤四， 当手指移回感应节点 （A) 时， 屏幕显示该感应节点此时对应的信 号和 /或信号集合（类似于实施例 6之步骤六屏幕所产生的变化）， 通常此时对应 的拾取信号改变为步骤二对应的拾取信号；
步骤五， 手指离开感应区域， 产生取消 （上一操作） 或擦除的信号。
可见， 在开始的若干步骤中， 取消（擦除）操作与回退操作可能存在相同的 操作步骤， 随着步骤五的执行， 表明产生的是取消 （擦除） 信号， 而不是回退， 即最后的步骤五才决定上述操作为取消（擦除）操作而不是其他。如果在步骤五 手指不离开感应区域，而是继续滑动的第二特征动作或按压之类确认输入的第三 特征动作， 则表明步骤一至步骤五只是一个回退操作， 目前处于信号调整与输入 阶段。 与取消（擦除）操作相比， 回退不是一个独立的操作， 但回退操作可以嵌 入其他操作之中。
当然， 可以设定一个快速的回搓动作： 即如果手指在两个相邻节点之间的往 返滑动足够快， 并且立刻离开感应区域， 可以直接执行取消（擦除）操作， 而屏 幕不产生上述步骤一至步骤四所涉及的变动。 实施例 13: 拼音词组输入 "和平，"
该实施例对硬件有一定的要求， 除包括一个感应键盘外，建议至少一个具备 选择功能的装置或区域， 如触摸屏、选择按钮等， 本实施例以感应键盘与触摸屏 的组合为例进行描述。
步骤一至五同实施例 7步骤一至五
步骤六， 此时已输入的拼音为 "he", 触摸屏除提示可供选择的拼音字符如 " i、 n "外 （其中优选字符反白）， 还显示可供选择的汉字如： "合、 和、 河"等 (如果直接点击 "和"所在的区域可输入该汉字）， 手指离开感应键盘。
步骤七， 手指触摸按键 7并按下， 表明输入字符 "p"。
步骤八， 此时触摸屏提示可供选择的组合， 如 "和平、 河畔、 合拍"等， 按 下 "和平"所在的区域， 表明输入该词。
步骤九， 手指滑过图五所示键盘中两斜向键位， 如键位 "5 "与 "7"或者是 键位 "6"与 "8"， 之后手指即离开键盘。
步骤十， 屏幕显示与上述斜向划线操作相关的字符， 并将最优先的字符"， " (逗号） 输入， 如果需要调整可以根据屏幕相关提示进行操作。
注： 本实施例不排斥其他可能的设定， 如步骤八中， 还可在输入正文区即显 示最优选的词 "和平"， 等待短暂时间后即自行输入。
本实施例将感应笔画输入或者手写输入融入其中，感应笔画输入是 "一种输 入方法和输入设备"（申请号为 200910107777.7 )中所描述的输入控制方法。通 常情况下，基于感应的手写、笔画与本发明所述的输入方式的结束动作可以有所 不同， 如当第三特征动作定义为 "按下"时， 笔画或手写输入通常以 "离开"或 "停留后离开 "为结束， 这样就将两类不同的信号区别开来， 从而据此输入相关 信号。也可以设置特别的结束点或区域以配合输入， 如可设一结束点， 当中途希 望终止操作时， 以该点为手指移动的终点即可。
当屏幕不具备触摸功能， 可调整为：
步骤八， 此时触摸屏显示可供选择的组合， 如 " 1和平、 2河畔"等。
步骤十， 长按按键 " 1 "， 表明输入其代表的词 "和平"。
本方法也可以与传统的按键输入相融合，如 Qwert布局的感应键盘可直接采 用按键输入，而在图五所示的数字键盘经过设置也可使用本输入法的同时融合按 键输入。 这是本领域技术人员易于想到的， 这里不做详细论述。
虽然本发明是通过具体实施例进行说明的， 本领域技术人员应当明白， 在不 脱离本发明范围的情况下， 还可以对本发明进行各种变换及等同替代。 因此， 本 发明不局限于所公开的具体实施例，而应当包括落入本发明权利要求范围内的全 部实施方式。
