Description

用电容屏手写笔模拟左右键输入的方法、 电容屏手写笔及终端
技术领域 本发明主要涉及电子应用领域， 尤其涉及一种用电容屏手写笔模拟左右 键输入的方法、 电容手写笔及终端。
背景技术
在电子产品终端手写输入领域， 目前有两种方案最为常见， 一种是电阻 屏输入， 另一种是电容屏输入。
电阻屏输入方式的原理为： 当手写笔在触摸屏上进行书写时， 由于接触 压力的变化使屏幕接触部分发生变形， 从而改变该点的电阻值， 进一步通过 屏幕四个角的阻值变化检测计算出书写的位置。 电阻屏的特点在于： 对于输 入的装置无特殊要求， 并且价格较为低廉， 但是它无法支持多点触摸的识别。 该方式目前在大量中低端触摸屏手机上广泛使用。
电容屏的输入方式原理为： 在屏幕中内置电容感应器件， 当有电荷的物 体足够接近时， 电容感应器件的相应位置就会产生感应电荷， 通过对感应电 荷所处行列的检测来判断操作的位置。 电容屏可以支持多点触控， 但对于输 入介质具有一定的要求， 一般来说具有电荷的物质才可输入， 常用方式为人 的手指输入， 目前也有一些使用特殊手写笔进行输入的技术。
另一方面， 随着 Pad (平板电脑）类产品的产生， 移动终端与平板电脑 越来越接近， 在苹果发行的 iPad上， 已经具有了通过其接口连接键盘使用的 功能。 苹果公司在中国、 欧洲和美国申请的双底座接口 iPad专利 （美国专利 申请号为 USD627777S1 )， 其目的之一也是为了使 iPad在横屏状态下扩展键 盘更加方便。 Pad加上键盘已经具有了一些平板电脑的雏形， 如果再加上左 右键控制方式， 即模拟电脑鼠标的左右键控制方式， 则会与电脑更加接近。
在手写笔领域中， 目前能够在书写和操作中检测左右键的技术很少， 如 申请号为 CN200810217607. X的手写笔及其输入方法， 是通过检测书写时手 机笔的倾斜角度来模拟左右键输入。 如： 点击时手写笔向左倾斜则判定为左 键输入， 向右倾斜则判定为右键输入。 该方法在电阻屏和电容屏上都可以使 用， 但是其操作方法不符合用户习惯， 用户体验不够友好。

为使本发明的目的、 技术方案和优点更加清楚明白， 下文中将结合附图 对本发明的实施例进行详细说明。 需要说明的是， 在不冲突的情况下， 本申 请中的实施例及实施例中的特征可以相互任意组合。
本发明所述的模拟左右键输入， 是指模拟鼠标的左右键点击输入。
在本实施例中， 一种用电容手写笔模拟左右键输入的方法， 应用于配置 有电容手写笔的终端中， 该终端设置有电容屏， 如图 1所示， 该方法包括：
1、 当接收到用户选择进行左键输入或右键输入的命令后，上述电容手写 笔输出与上述用户所选择的输入方式所对应的调制信号；
2、 上述终端如判断出上述电容屏通过与上述电容手写笔接触而接收到 上述调制信号， 则按照该调制信号所对应的输入方式执行相应的输入操作。 即： 如该调制信号与左键输入方式对应， 则执行左键输入操作； 若该调制信 号与右键输入方式对应， 则执行右键输入操作； 若为判断出电容屏接收到调 制信号， 则不进行反应， 方法结束。
如图 2所示， 是本实施例中电容手写笔部分的处理流程。 该电容手写笔 具有切换左右键输出的功能， 包括：
假设当前输出方式为左键（右键）输出， 当用户选择将输出方式调节为 右键（左键）输出时， 电容手写笔将调制方式进行更改， 更改为输出右键（左 键）方式对应的电信号。
假设当前输出方式为左键（右键）输出， 当用户再次选择左键（右键） 输出时， 电容手写笔不进行响应， 仍然输出原有方式对应的电信号。
由于存在着不同的用户控制方式， 可能上述流程不适用于所有的情况， 如当使用左右滑块或双掷开关进行左右键输入方式选择的时候， 就不存在在 左键状态下用户再次选择进行左键输入的情况。 但各种不同情况至少可符合 本流程图中的部分支线流程或节点。
如图 3所示， 本示例中配有电容屏的终端的相关流程， 包括：
1、本示例中所示的终端在监测到电容屏上有电容手写笔进行输入后， 根 据事先协议商定的釆样周期和釆样个数进行多周期釆样；
2、 对釆样的结果进行识别， 如果与协议约定的左键输入信号匹配， 则执 行电容手写笔左键输入操作； 否则， 执行下一步骤；
3、如果与协议约定的右键输入信号匹配， 则执行电容手写笔右键输入操 作； 否则， 执行下一步骤；
4、如果釆样结果与已有的左键和右键输入信号都不匹配， 则按照非左右 键输入方式进行处理。
如图 4所示， 是本示例中电容手写笔的结构示意图。 该电容手写笔由电 源模块、 左右键切换输入模块、 控制电路模块及电信号发射模块组成。
电源模块设置为为手写笔中的左右键切换输入模块、 控制电路模块及电 信号发射模块供电， 提供电容手写笔工作需要的必须电量；
左右键切换输入模块是用户操作的输入部分， 该部分设置为接收用户发 出的左右键控制操作并发出相应的操作信息， 当用户使用该左右键切换输入 结构时， 手写笔可以实现区分控制左右键输入的功能。 当前， 除了本图中给 出的分设的左右按键的形式外， 还可以有其它实现方式；
控制模块是该电容手写笔中的核心控制和调制模块， 它接收左右键切换 输入模块发出的操作信息， 并根据该信息输出对应的调制方式信息以控制电 信号发射模块发射相应的电信号给终端。 在本实施例中， 调制方式并无限定， 可以是频率、 幅度或相位等方式， 也可以为最简单的开关脉冲等方式， 只要 终端与电容手写笔双方协议一致即可；
电信号发射模块设置为在接收到控制模块发出的调制方式信息后， 根据 该调制方式信息所指示的调制方式发射对应的电信号。 该电信号具有一定的 强度， 以使得终端上的电容屏能够正常地感应到它。
如终端接收到该调制后的电信号并能够正确辨认并响应， 则完成了对应 的输入过程。
需要说明的是， 如该电容手写笔的外壳釆用导电材料制作， 则电容手写 笔内部可以仅设置电源模块、 左右键切换输入模块、 控制电路模块， 不设置 电信号发射模块。 其中， 电源模块及左右键切换输入模块的功能与前述实例 相同， 控制电路模块所输出的电信号应为使用手写笔的用户导入该电容手写 笔中的电信号。
控制电路模块可以使用控制整个电路开闭的方式直接对该电信号进行调 制。 具体的说， 用户的手接触到电容手写笔的外壳部分经过手写笔的控制电 路模块和笔头相导通， 这样如果电容手写笔没有设置控制电路模块， 就相当 于用户握着一个金属笔， 金属笔的笔头将用户手上的电和触摸屏导通， 实现 输入。 当设置了控制电路模块以后， 控制电路模块可以控制用户的手到笔头 的这条导体路径是否开通， 更可以通过以特定频率开通关闭的方式实现向终 端进行电信号的传递，即向终端传递以一定频率进行高低电平转换的电信号。 终端通过该高低电平转换的频率来识别对应的左右键输入方式， 然后执行相 应的操作。
在本实施例中， 一种终端包括： 电容屏、 检测模块及执行模块； 检测模块设置为在判断出所述电容屏通过与电容手写笔接触而接收到用 于表示左键输入方式或右键输入方式的调制信号后， 向所述执行模块发送执 行命令； 其中， 所述执行命令用于指示所述执行模块按照与所述调制信号所 表示的输入方式执行输入动作；
执行模块设置为按照接收到的上述执行命令执行相应的输入动作。
较优地， 用于表示左键输入方式的调制信号与所述用于表示右键输入方 式的调制信号的频率、 幅度或相位中的任意一项或任意组合不同。
图 5为本示例中列举的左右键切换输入模块的几种具体实现的实例， 其 中：
图 5 ( a )为左右拨动滑块或双掷开关来选择左右键输入的实例， 在该实 例中， 用户将滑块或双掷开关拨动到左侧， 则代表左键输入， 拨动到右侧则 代表右键输入。 图 5 ( b )为单键切换操作方式的实例， 在该实例中， 如当前状态为左键 (右键）输入， 当用户按下该键， 则切换为右键（左键）输入；
图 5 ( c )为双键选择操作方式的实例， 在该实例中， 当用户按下左边按 键时， 手写笔以左键方式输出， 当用户按下右边按键时， 手写笔以右键方式 输出。
操作实例可能还有其它情况， 由于篇幅限制， 这里无法列举全部， 但凡 与本发明思想相符的其它实例也应属于本发明保护范围。
图 6是本示例中左右键输出时不同调制方法的实例图。
图 6 ( a ) 中以无变化的电信号表示左键输入， 以一定频率和数量的 0-1 电信号表示右键输入。 其特点在于， 当用户无本发明所述手写笔时， 还可以 使用手指等其它方式在电容屏上进行左键操作。 广义上说可以称为调制方式 的
图 6 ( b ) 中以低频的 0-1电信号表示左键输入， 以高频的 0-1电信号表 示右键输入。 其特点在于， 本方式完全杜绝了手指等其它一些手写操作方式 的可能性， 由于非特殊手写笔无法向触摸屏发出 0-1 电信号， 因此只有本示 例中所述手写笔才能够使终端的屏幕操作产生响应， 因此具有一定的加密保 密作用。
图 6所示仅为两个调制方式的实例， 本领域的相关人员应知， 已有的调 制方式大小分类较多， 除上述实施例外， 还可进行相位、 幅度的调制等， 此 处无法穷尽列举， 无论何种方式， 只要符合本发明基本精神， 都应属于本发 明所述范围。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。 以上所述仅为本发明的优选实施例而已， 并非用于限定本发明的保护范 围。 根据本发明的发明内容， 还可有其他多种实施例， 在不背离本发明精神 改变和变形， 凡在本发明的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
工业实用性
本发明提供一种用电容手写笔模拟左右键输入的方法、 电容手写笔及终 端， 以克服现有的电容屏手写输入无法进行左右键输入的弊端。 通过在手写 笔内部加入调制器件等 ,让用户可以方便的在手写笔上进行左右键输入操作 , 使手机的部分功能与平板电脑更为接近， 也为用户提供了一个灵活进行左右 键操作的实用平台。 此外， 在本发明的实施中， 若釆用左右键两个键的调制 方式均与普通手写笔输入不同的技术方案， 则会起到一定的加密作用， 即只 能使用该手写笔在所述触摸屏手机上进行操作， 即使手机丟失， 如果对方没 有专用手写笔， 也无法对手机进行操作， 客观上起到了一定的信息保密作用。
