背景技术 随着技术的日新月异， 无论是笔记本电脑、 手机或是可携式多媒体播放器等电子装 置的制造商， 皆有利用触控面板来取代传统键盘以作为新一代输入界面的趋势。 更详细 而言， 目前的触控面板大致可分为电容式触控面板以及电阻式触控面板。 以 iPhone为 例， iPhone采用电容式触控面板作为输入界面， 因此使用者只需用手指便可进行输入文 字或选取菜单等操作。 然而现有触控笔需接触触控屏进行操控， 操控不够方便， 快捷。
发明内容 本发明实施例的目的在于提供一种电子装置， 旨在解决现有电子装置的触控笔需直 接接触触控屏进行操控， 操控不够方便， 快捷的问题。
本发明实施例是这样实现的， 一种电子装置， 其设至少一用以获取外部磁场变化， 据此控制屏幕所显示内容的磁感应器。

具体实施方式 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例， 对 本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明， 并不用于限定本发明。
本发明实施例于电子装置内设至少一用以获取外部磁场变化，据此控制屏幕所显示 内容的磁感应器， 此时只需将磁性笔靠近电子装置即可进行相应的操控， 方便， 快捷。
以下结合具体实施例对本发明的实现进行详细描述。在以下各实施例中电子装置可 为手机、 平板电脑等。
实施例一
如图广 3所示， 本发明实施例提供的电子装置 1设至少一用以获取外部磁场变化， 据此控制屏幕所显示内容的磁感应器 10。此时只需将磁性笔 2靠近电子电子装置 1即可 进行相应的操控， 方便、 快捷。 本实施例将长条形磁铁作为磁性笔 2， 仅由电子装置 1 内的磁感应器 10即可监控磁性笔 2的移动情况， 使本电子装置结构简单， 成本低。
为使所述磁感应器 10准确获取外部磁场的变化， 需考虑环境固有磁场影响。 环境 固有磁场包括两个部分： 一个是电子装置 1 内部磁性器件 （如 Receiver等音频器件） 产生的磁场，一个是地磁引力。 由于电子装置 1内部磁性器件的引力相对于磁感应器 10 的位置以及大小是固定的， 地磁引力的方向以及大小也是固定， 因此可以在计算中加以 考虑并删除其影响。
在此提供电子装置 1内部器件磁力影响的消除方法： 现有磁感应芯片都具备对电子 装置 1内部磁感应器 10进行纠正校准功能。 由于电子装置 1内部结构是固定的， 电子 装置 1 内部磁性器件 （如 Receiver等音频器件） 产生磁力的特点是， 其产生的磁力相 对于磁感应器来讲方向和大小都是相对固定的。 现在的磁感应芯片都具备自校准功能， 只要将电子装置晃动几下， 就可以充分估算出这种固定磁力的值以及方向， 并在后续测 量中去除这部分磁力影响。
在此还提供地磁引力影响的消除方法： 地磁引力的特点是， 其绝对方向和大小是固 定的， 即随着电子装置的移动和翻转， 始终有一个绝对方向上的引力。 因此， 在磁性笔 移近电子装置之前， 只要根据当前 G-sensor的信息判断电子装置当前的姿态， 再根据 磁感应器得到的磁力测量数据， 就可以知道当前状态下地磁力的方向 （大小是固定的， 可以预先设置）。 用户在使用电子装置的时候， 如果基本上保持静止不动 （可以根据 G-sensor信息得到）， 则可以根据使用磁性笔之前时刻地磁感应的测量方向， 作为本次 操作中地磁的方向的参考值，并在最终计算中予以删除。如果用户是做在车中进行操作， 由于车辆一般也不会频繁转弯， 因此也可以使用某一次磁性笔移近电子装置之前的地磁 引力方向测量值作为参考校准值。 此外， 考虑到磁性笔的磁力远大于地磁力， 因此即便 有点干扰， 对最终计算结果的影响也有限。
具体地，所述磁性笔 2垂直于或接近垂直于所述电子装置 1的屏幕时作为信息输入 器件使用； 此时将所述磁性笔 1其中一个磁极作为输入端 21， 所述磁感应器 10则根据 靠近所述屏幕的输入端 21 于空中移动所形成的轨迹输入所述信息。 而将所述磁性笔 2 另一磁极作为删除端 22，所述磁感应器 10则根据靠近所述屏幕的删除端 22于空中移动 所形成的轨迹选择所述信息并删除。 删除信息时， 只需将磁性笔 2掉个头即可进行相应 的操作， 更加方便， 快捷。 其中， 所述信息包括但不限于字符及图像。
例如， 电子装置系统预置磁性笔 N极为输入端 21，用户垂直于电子装置 1屏幕拿着 磁性笔 2， N极靠近电子装置 1屏幕， S极远离电子装置 1屏幕时， 即可进行写字符或者 画图等操作。 用户于空中移动磁性笔 2， 磁感应器 10每隔一段时间 （如 10ms ) 读取三 个磁性感应轴上的数据 （x、 y、 z ), 并根据这个数据确定磁性笔 N极的具体空间坐标。 随着磁性笔 2的移动， 磁感应器 10读取的 （x、 y、 z )三轴数据也在不断变化， 将各个 时间点采集的空间坐标连接起来， 就是磁性笔 2在空中的移动轨迹， 将此轨迹作为手写 输入模块的输入信息， 即可完成输入功能。
又如，本电子装置系统预置磁性笔 S极为删除端 22， 当用户垂直于电子装置 1屏幕 拿着磁性笔 2， S极靠近电子装置 1屏幕， N极远离电子装置 1屏幕时， 即可删除字符或 者图像， 此时磁性笔 2相当于橡皮擦。 磁感应器 10每隔一段时间 （如 10ms ) 读取三个 磁性感应轴上的数据 （x、 y、 z ), 并根据这个数据确定磁性笔 S极的具体空间坐标。 随 着磁性笔 2的移动， 磁感应器 10读取的 （x、 y、 z )三轴数据也在不断变化， 将各个时 间点采集的空间坐标连接起来， 就是磁性笔 2在空中的移动轨迹， 信息删除模块即可将 该移动轨迹上的字符、 图形等信息擦除掉。
本发明实施例根据磁感应芯片读取的数据特点判断磁性笔 2相对于电子装置 1屏幕 的位置关系。 如前所述， 本磁性笔 2由一长条磁铁制成， 其特点是， 在接近磁性笔两端 磁极的位置， 磁力很强， 且具备明确的方向性， 但是远离一点， 磁力就立刻变弱了。
当用户垂直于电子装置 1屏幕拿着磁性笔 2， 其 N极靠近电子装置 1屏幕时， 则会 给磁感应器 10—个明显的垂直于电子装置 1屏幕向下的磁力， 此时可认为磁感应器的 磁性与磁性笔的 N极相同。 这样， 一个磁感应器感应到的当前磁力的特点是， Z轴 （垂 直于电子装置屏幕向上） 的数据将是明显的负值。 如果满足这个条件， 则可以判断出用 户是垂直方向操作磁性笔且用 N极端靠近了电子装置。 此时的磁性笔可输入各种信息。
同样地， 当用户垂直于电子装置 1屏幕拿着磁性笔 2， 其 S极靠近电子装置 1屏幕 时， 则会给磁感应器 10—个明显的垂直于电子装置 1屏幕向上的磁力， 此时磁感应器 的磁性与磁性笔的 N极相反。这样，一个磁感应器感应到的当前磁力的特点是， Z轴（垂 直于电子装置屏幕向上） 的数据将是明显的正值。 如果满足这个条件， 则可以判断出用 户是垂直方向操作磁性笔且用 s极端靠近了电子装置。 此时的磁性笔可删除各种信息。
为保证用户完成一个操作后， 在想进行下一个操作前， 两个操作之间的磁性笔 2移 动不会被电子装置 1误判断。于所述电子装置 1设一将两个相邻信息区分开依次输入或 删除的复位按键 3， 所述复位按键 3的作用是确认什么时候开始判断磁性笔的移动。 当 用户按下复位按键 3时， 即打开监控磁性笔 2动作功能的开关， 由电子装置 1内部处理 器读取磁感应器 10 的数据， 判断当前磁性笔的位置和状态， 并以此位置和状态作为初 始状态， 然后用户对磁性笔 2 的任何移动， 电子装置内部处理器都会通过磁感应器 10 获取相关数据， 如此实现磁性笔移动初始位置的确认。 当用户想进行一次新的操作的时 候， 例如用户输入完一个字符， 想输入第二个字符的时候， 用户可以再按一下复位按键 3， 先暂时关闭监控磁性笔动作的功能， 等用户将磁性笔 2拿回起始位置后， 再重新打 开， 即再次按一下复位按键 3。
本发明实施例还可于输入或删除两个相邻信息间设将它们区分开的复位时间或复 位距离， 所述复位时间一般设为 0. 2〜0. 4s， 所述复位距离一般设为 0. 5〜1. 5cm。 例如， 用户输入完一个字符，想输入下一个字符的时候，在输入完前一个字符的位置停顿 0. 3s, 磁感应器 10 即认为用户将输入下一个字符。 或者， 用户输入完一个字符， 想输入下一 个字符的时候， 将磁性笔 2提起 lcm后回到原来位置， 磁感应器 10即认为用户将输入 下一个字符。
在此输入或删除信息， 需移动磁性笔 2， 移动磁性笔 2将造成磁感应器三轴读取数 据的变化。 其实， 根据一个磁感应器上 X/Y/Z三轴的磁性数据， 就可以判断出磁性笔 2 的空间位置及其移动轨迹。
本发明实施例提供的磁性笔 2还具有方向控制功能，所述磁性笔 2平行于或接近平 行于所述电子装置 1的屏幕时作为方向控制器件使用； 当所述磁性笔 2向上、 向下、 向 前、 向后、 向左或向右移动时， 所述磁感应器 10根据所述磁性笔 2移动产生的磁场变 化对所述屏幕显示的内容（如 3D画面）进行相应的方向控制。 此时一个磁感应器 10将 获取磁性笔 2向上、 向下、 向前、 向后、 向左或向右移动产生的磁场变化， 从而判断磁 性笔 2的移动方向并实现三维方向控制， 方向控制直观， 提升用户使用感受。
例如， 磁感应器 10判断磁性笔 2当前平行于电子装置 1屏幕， 则表示用户希望控 制方向。 此时磁感应器 10每隔一段时间 （如 10ms )读取 （x、 y、 z )三个磁性感应轴上 的数据， 并根据这个数据确定磁性笔 N极和 S极的具体空间坐标， 从而获取出当前磁性 笔 N极和 S极的空间位置。 用户将磁性笔 2平行于电子装置 1屏幕往上移动时， 磁感应 器 10根据磁性笔 N极、 S极的空间位置变化， 判断出磁性笔 2的空间位置往上移， 从而 控制所述屏幕显示的内容 （如 3D画面） 往上移动。 同样， 可以判断用户进行下、 左、 右等方向的控制操作。
实施例二
为更加准确获取外部磁场变化， 于所述电子装置 1 内设第一磁感应器 11和第二磁 感应器 12，所述第一磁感应器 11和第二磁感应器 12分位于所述电子装置 1的左、右两 侧， 如图 7所示。 当然， 磁感应器越多， 操控越精准。 所述磁性笔 2平行于或接近平 行于所述电子装置 1的屏幕时， 两个磁感应器的 Z轴读取数据， 将一个为正一个为负， 通过这个条件即可进行判断。
例如，第一磁感应器 11和第二磁感应器 12判断磁性笔 2当前平行于电子装置 1屏 幕， 则表示用户希望控制方向。 此时第一磁感应器 11和第二磁感应器 12每隔一段时间 (如 10ms ) 读取 （x、 y、 z ) 三个磁性感应轴上的数据， 并根据这个数据确定磁性笔 N 极和 S极的具体空间坐标， 从而获取出当前磁性笔 N极和 S极的空间位置。 用户将磁性 笔 2平行于电子装置 1屏幕往前移动时，第一磁感应器 11和第二磁感应器 12根据磁性 笔 N极、 S极的空间位置变化， 判断出磁性笔 2的空间位置往前移， 从而控制所述屏幕 显示的内容 （如 3D画面） 往前移动。 同样， 可以判断用户进行下、 左、 右等方向的控 制操作。
此外， 当用户垂直于电子装置 1屏幕拿着磁性笔 2， 其 N极靠近电子装置 1屏幕， 此时两个磁感应器感应到的当前磁力的特点是， Z轴 （垂直于电子装置屏幕向上） 的数 据将是明显的负值， X轴上， 位于屏幕左侧的第一磁感应器 11读取值为负值， 位于屏幕 右侧的第二磁感应器 12读取值为正值， 如图 5所示。 如果满足这三个条件， 则可以判 断出用户是垂直方向操作磁性笔 2且用 N极端靠近了电子装置 1。 此时的磁性笔 2可输 入各种信息。 其中， 所述信息包括但不限于字符及图像。
例如， 电子装置系统预置磁性笔 N极为输入端 21，用户垂直于电子装置 1屏幕拿着 磁性笔 2， N极靠近电子装置 1屏幕， S极远离电子装置 1屏幕时， 即可进行写字符或者 画图等操作。 用户于空中移动磁性笔 2， 磁感应器每隔一段时间 （如 10ms )读取三个磁 性感应轴上的数据 （x、 y、 z ), 并根据这个数据确定磁性笔 N极的具体空间坐标。 随着 磁性笔 2 的移动， 磁感应器读取的 （x、 y、 z ) 三轴数据也在不断变化， 将各个时间点 采集的空间坐标连接起来， 就是磁性笔 2在空中的移动轨迹， 将此轨迹作为手写输入模 块的输入信息， 即完成输入功能。
同样地， 当用户垂直于电子装置 1屏幕拿着磁性笔 2，其 S极靠近电子装置 1屏幕， 此时两个磁感应器感应到的当前磁力的特点是， Z轴 （垂直于电子装置屏幕向上） 的数 据将是明显的正值， X轴上， 位于屏幕左侧的第一磁感应器读取值为正值， 位于屏幕右 侧的第二磁感应器读取值为负值。 如果满足这三个条件， 则可以判断出用户是垂直方向 操作磁性笔且用 S极端靠近了电子装置。 此时的磁性笔可删除各种信息。
又如，本电子装置系统预置磁性笔 S极为删除端 22， 当用户垂直于电子装置 1屏幕 拿着磁性笔 2， S极靠近电子装置 1屏幕， N极远离电子装置 1屏幕时， 即可删除字符或 者图像， 此时磁性笔相当于橡皮擦。磁感应器每隔一段时间（如 10ms )读取三个磁性感 应轴上的数据 （x、 y、 z ), 并根据这个数据确定磁性笔 S极的具体空间坐标。 随着磁性 笔 2 的移动， 磁感应器读取的 （x、 y、 z ) 三轴数据也在不断变化， 将各个时间点采集 的空间坐标连接起来， 就是磁性笔 2在空中的移动轨迹， 信息删除模块即可将该移动轨 迹上的字符、 图形等信息擦除掉。
另外，所述磁性笔 2平行于或接近平行于所述电子装置 1的屏幕时还作为角度控制 器件使用； 当所述磁性笔 2在原来位置顺时针或逆时针旋转时， 所述第一磁感应器 11 和第二磁感应器 12根据所述磁性笔旋转产生的磁场变化对所述屏幕显示的内容进行相 应的角度控制。 当磁性笔从图 6所示的水平方向偏转一个角度至图 7所示的倾斜方向， 则由于电子装置 1左侧第一磁感应器 11主要受 N极影响， 而右侧第二磁感应器 12主要 受 S极影响， 两个磁感应器将分别判断出两个磁极的空间相对位置， 将这两个相对位置 连接后与水平线进行对比， 即能判断出磁性笔 2的大致偏转方向及角度。 相应地， 所述 电子装置内设用以控制屏幕所显示内容的角度的角度控制模块。
本发明实施例于电子装置内设至少一用以获取外部磁场变化，据此控制屏幕所显示 内容的磁感应器， 此时只需将磁性笔靠近电子装置即可进行相应的操控， 方便， 快捷。 前述磁性笔平行于或接近平行于所述电子装置的屏幕时作为方向控制器件使用，此时磁 感应器将获取磁性笔向上、 向下、 向前、 向后、 向左或向右移动产生的磁场变化， 从而 判断磁性笔的移动方向并实现三维方向控制，方向控制直观，提升用户使用感受。此外， 将长条形磁铁作为磁性笔， 仅由电子装置内的磁感应器即可监控磁性笔的移动情况， 使 本电子装置结构简单， 成本低。
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的精神 和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保护范围之内。
