具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此 处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
实施例一
图1为本发明实施例一提供的一种电磁笔的结构示意图。参见图1，本实施例提供的电磁笔包括：笔体110，笔体110内设置有电源模块120，笔体110的第一端设置有第一电磁发射模组130，笔体110的第二端设置有第二电磁发射模组140。其中，第一电磁发射模组130和第二电磁发射模组140发射的电磁信号的频率不同。
具体的，电源模块120可分别与第一电磁发射模组130和第二电磁发射模组140连接，用于为第一电磁发射模组130和第二电磁发射模组140提供电源，以使第一电磁发射模组130和第二电磁发射模组140正常工作。
示例性的，第一电磁发射模组130和第二电磁发射模组140中均包括有谐振电路以发射特定频率的电磁信号。
可选的，第一电磁发射模组130发射的电磁信号的频率可为160kHz，第二电磁发射模组140发射的电磁信号的频率可为310kHz。
具体的，对于电磁笔，均有与其配套使用的电磁感应板，其中，电磁感应板可由位于横向和纵向分布的线圈阵列组成，当某一频率的电磁信号靠近电磁感应板时，电磁感应板中不同位置的线圈可感应到不同振幅的该频率的电磁信号，进而根据不同位置的线圈接收到的该频率的电磁信号的振幅可得到该频率的电磁信号对应的坐标。
示例性的，可通过电磁感应板接收到的电磁信号频率的不同实现与智能终 端之间不同的交互操作。如若第一电磁发射模组130发射的电磁信号的频率为A，第二电磁发射模组140发射的电磁信号的频率为B，则当仅第一电磁发射模组130靠近电磁感应板，通过电磁感应板接收到频率A的电磁信号时，获取电磁信号对应的坐标移动轨迹，并将获取的坐标移动轨迹确认为书写轨迹发送至智能终端，智能终端接收到书写轨迹后，对该书写轨迹进行显示；当仅第二电磁发射模组130靠近电磁感应板，通过电磁感应板接收到频率B的电磁信号时，则获取电磁信号对应的坐标移动轨迹，并将获取的坐标移动轨迹确认为待擦除轨迹发送至智能终端，智能终端接收到待擦除轨迹后，对待擦除轨迹进行擦除。当然，也可以频率A和频率B对应的电磁信号均表示书写，并为不同频率的电磁信号对应的轨迹进行不同的显示，例如颜色或线型的不同。由此，通过两种不同频率的电磁信号的电磁笔可增加用户与智能终端之间的交互操作。
可选的，电磁笔110还包括笔头，通过笔头可在纸张上进行正常书写。笔体120的第一端可为靠近笔头的一端，笔体120的第二端可为靠近笔尾的一端。由此，对于可将纸张放置于电磁感应板之上的电子设备而言，当用户在纸张上进行书写或者绘画等操作时，通过电磁感应板可接收到第一电磁发射模组130发射的电磁信号，进而确定电磁信号对应的坐标，获取用户的书写轨迹，以对书写轨迹进行保存、发送或显示。
可选的，笔体120还设置有压力传感器，当用户手执电磁笔110进行书写时，会对电磁笔110(笔头)进行施压，当压力传感器感受到压力，得到相应的压力数据之后，可将压力数据传送至显示设备的处理器，以根据压力的不同通过显示设备对用户的书写轨迹以粗细不同的线条进行客观反映。
可选的，笔体110内还可设置有与电源模块120连接的开关模块，当开关 模块处于开启状态时，电源模块120为第一电磁发射模组130和第二电磁发射模组140提供电源，第一电磁发射模组130和第二电磁发射模组140正常工作，发射电磁信号，当开关模块处于关闭状态时，电源模块120停止为第一电磁发射模组130和第二电磁发射模组140提供电源，第一电磁发射模组130和第二电磁发射模组140处于休眠状态，不发射电磁信号，从而达到节能的目的。
本实施例提供的电磁笔通过包括有笔体，笔体内设置有电源模块，笔体的第一端设置有第一电磁发射模组，笔体的第二端设置有第二电磁发射模组，可实现同时发射两个电磁信号，其中，第一电磁发射模组和第二电磁发射模组发射的电磁信号的频率不同，进而可通过电磁笔使得电磁感应板接收不同频率的电磁信号，进一步可根据不同的接收情况实现不同的交互操作，增加与用户之间的交互。
实施例二
图2为本发明实施例二提供的一种智能终端的控制方法的流程图。本实施例可适用于需对智能终端进行控制的情况，该方法可以由智能终端的控制装置来执行，该装置可由软件和\或硬件组成。参见图2，本实施例提供的方法具体包括如下步骤：
步骤210、通过预设连接方式与至少一个智能终端建立通信连接。
其中，预设连接方式可为蓝牙连接或网络连接等连接方式，本发明对此不进行限定，只要通过预设连接方式可与智能终端建立通信连接便可。
其中，智能终端可为智能平板、智能手机、智能电视或电子白板等智能终端。
步骤220、通过电磁感应板同时接收到两个电磁信号时，获取电磁信号对应的坐标的变化状态。
示例性的，电磁信号可由本实施例一中提供的电磁笔发射，当用户将电磁笔的第一电磁发射模组和第二电磁发射模组同时靠近电磁感应板时，则通过电磁感应板可同时接收到两个电磁信号，并可获取两个电磁信号对应的坐标，根据获取的两个电磁信号对应的坐标可确定两个电磁信号对应的坐标的变化状态。
优选的，变化状态包括：两个电磁信号对应的坐标维持不变达到预设时长、两个电磁信号对应的坐标顺时针移动、两个电磁信号对应的坐标逆时针移动和两个电磁信号对应的坐标平行移动中的至少一个。
可选的，变化状态还可包括：一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标顺时针移动或者逆时针移动。
具体的，对于确定两个电磁信号对应的坐标维持不变达到预设时长、两个电磁信号对应的坐标顺时针移动、两个电磁信号对应的坐标逆时针移动和两个电磁信号对应的坐标平行移动的方式有很多，本发明对此不进行限定。
如对于确定两个电磁信号对应的坐标维持不变达到预设时长，可将通过电磁感应板同时接收到两个电磁信号的初始时刻获取的两个电磁信号对应的坐标作为初始坐标，将达到预设时长时获取的最新的两个电磁信号对应的坐标作为终止坐标，若两个电磁信号对应的初始坐标与终止坐标之间对应坐标值之差的绝对值均小于第一预设阈值，则确定两个电磁信号对应的坐标维持不变达到预设时长。
图3为本实施例提供的两个电磁信号对应的坐标顺时针移动的示意图。图3中以[(x A1，y A1)，(x B1，y B1)]、[(x A2，y A2)，(x B2，y B2)]、[(x A3，y A3)， (x B4，y B4)]和[(x A5，y A5)，(x B5，y B5)]为在通过电磁感应板同时接收到两个电磁信号时依次获取的两个电磁信号对应的坐标为例，其中，(x An，y An)为一个频率的电磁信号对应的坐标，(x Bn，y Bn)为另一个频率的电磁信号对应的坐标。则当获取到一个最新两个电磁信号对应的坐标[(x An，y An)，(x Bn，y Bn)]时，可确认|x An|相对于|x An-1|的增长方向与|x Bn|相对于|x Bn-1|的增长方向是否相反，以及|y An|相对于|y An-1|的增长方向与|y Bn|相对于|y Bn-1|的增长方向是否相反，其中增长方向包括增大和减小，若是，则将[(x An，y An)，(x Bn，y Bn)]保存至第一预设列表，且将第一个数加1，并确认第一个数是否达到第一预设个数，若确认达到第一预设个数，则获取第一预设列表中各坐标[(x An，y An)，(x Bn，y Bn)]对应的中点坐标(x Cn，y Cn)并获取任意三个中点坐标构成的三角形的重心坐标(x D，y D)，确认各中点坐标(x Cn，y Cn)与重心坐标(x D，y D)之间对应坐标值之差的绝对值是否均小于第二预设阈值，若是，则确认两个电磁信号对应的坐标为旋转移动，以重心作为原点，对第一预设列表中保存的各坐标[(x An，y An)，(x Bn，y Bn)]进行坐标变换，获取坐标变换后的坐标[(x An’，y An’)，(x Bn’，y Bn’)]，并获取坐标变换后的坐标中的任意两组坐标，如获取[(x A1’，y A1’)，(x B1’，y B1’)]和[(x A2’，y A2’)，(x B2’，y B1’)]，并确认(x A1’，y A1’)和(x A2’，y A2’)是否满足：当x A1’和x A2’均大于0时，y A2’小于y A1’，或者当x A1’和x A2’均小于0时，y A2’大于y A1’，或者，当y A1’和y A2’均大于0时，x A2’大于x A1’，或者当y A1’和y A2’均小于0时，x A2’小于x A1’，以及(x B1’，y B1’)和(x B2’，y B2’)是否满足：当x B1’和x B2’均大于0时，y B2’小于y B1’，或者当x B1’和x B2’均小于0时，y B2’大于y B1’，或者，当y B1’和y B2’均大于0时，x B2’大于x B1’，或者当y B1’和y B2’均小于0时，x B2’小于x B1’，若是，则确认两个电磁信号对应的坐标顺时针移动；若 确认|x An|相对于|x An-1|的增长方向与|x Bn|相对于|x Bn-1|的增长方向不相反，或者|y An|相对于|y An-1|的增长方向与|y Bn|相对于|y Bn-1|的增长方向不相反，则确认两个电磁信号对应的坐标不为顺时针移动，同时可将预设列表中保存的坐标清除以及将第一个数初始化为0。
同理，对于确认两个电磁信号对应的坐标逆时针移动，其确认方式与确认两个电磁信号对应的坐标顺时针移动的方式类似，不同之处在于，获取坐标变换后的坐标中的任意两组坐标后，确认两组坐标的满足条件不同。如获取坐标变换后的两组坐标为[(x A1’，y A1’)，(x B1’，y B1’)]和[(x A2’，y A2’)，(x B2’，y B1’)]，则确认(x A1’，y A1’)和(x A2’，y A2’)是否满足：当x A1’和x A2’均大于0时，y A2’大于y A2’，或者当x A1’和x A2’均小于0时，y A2’小于y A1’，或者，当y A1’和y A2’均大于0时，x A2’小于x A1’，或者当y A1’和y A2’均小于0时，x A2’大于x A1’，以及(x B1’，y B1’)和(x B2’，y B2’)是否满足：当x B1’和x B2’均大于0时，y B2’大于y B1’，或者当x B1’和x B2’均小于0时，y B2’小于y B1’，或者，当y B1’和y B2’均大于0时，x B2’小于x B1’，或者当y B1’和y B2’均小于0时，x B2’大于x B1’，若是，则确认两个电磁信号对应的坐标逆时针移动。
图4为本实施例提供的两个电磁信号对应的坐标平行移动的示意图。图4中仍以[(x A1，y A1)，(x B1，y B1)]、[(x A2，y A2)，(x B2，y B2)]、[(x A3，y A3)，(x B4，y B4)]和[(x A5，y A5)，(x B5，y B5)]为在通过电磁感应板同时接收到两个电磁信号时依次获取的两个电磁信号对应的坐标为例，其中，(x An，y An)为一个频率的电磁信号对应的坐标，(x Bn，y Bn)为另一个频率的电磁信号对应的坐标。则当获取到一个最新两个电磁信号对应的坐标[(x An，y An)，(x Bn，y Bn)]时，可获取(x An，y An)与(x An-1，y An-1)构成的直线对应的斜率k An，并确认 k An与初始斜率k A2(即(x A2，y A2)与(x A1，y A1)构成的直线对应的斜率)之间差值的绝对值是否小于第三预设阈值，且(x An，y An)与(x An-1，y An-1)之间的距离D An是否大于设定距离，以及获取(x Bn，y Bn)与(x Bn-1，y Bn-1)构成的直线对应的斜率k Bn，并确认k Bn与初始斜率k B2(即(x B2，y B2)与(x B1，y B1)构成的直线对应的斜率)之间差值的绝对值是否小于第三预设阈值，且(x Bn，y Bn)与(x Bn-1，y Bn-1)之间的距离D Bn是否大于设定距离，若是，则确认两个电磁信号对应的坐标平行移动。
图5为本实施例提供的一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标顺时针移动的示意图。图5中仍以[(x A1，y A1)，(x B1，y B1)]、[(x A2，y A2)，(x B2，y B2)]、[(x A3，y A3)，(x B4，y B4)]和[(x A5，y A5)，(x B5，y B5)]为在通过电磁感应板同时接收到两个电磁信号时依次获取的两个电磁信号对应的坐标为例，其中，(x An，y An)为一个频率的电磁信号对应的坐标，(x Bn，y Bn)为另一个频率的电磁信号对应的坐标。则当获取到一个最新两个电磁信号对应的坐标[(x An，y An)，(x Bn，y Bn)]时，可分别确认一个电磁信号对应的最新坐标与该最新坐标的前一坐标，如(x An，y An)与(x An-1，y An-1)对应坐标值之差的绝对值是否均小于第四预设阈值，若是，则保存[(x An，y An)，(x Bn，y Bn)]至第二预设列表，且将第二个数加1，并确认第二个数是否达到第二预设个数，若达到第二预设个数，则从第二预设列表选取该电磁信号对应的坐标(x An，y An)中的任一坐标作为坐标原点，对第二预设列表中的另一个电磁信号对应的所有坐标(x Bn，y Bn)进行坐标变换，并确认进行坐标变换后的坐标(x Bn’，y Bn’)是否满足：当x Bn-1’和x Bn’均大于0时，y Bn小于y Bn-1’，或者当x Bn-1’和x Bn’均小于0时，y Bn’大于y Bn-1’，或者，当y Bn-1’和y Bn’均大于0时，x Bn’大于x Bn-1’，或 者当y Bn-1’和y Bn’均小于0时，x Bn-1’小于x Bn’，若是，则确认一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标顺时针移动。
同理，对于确定一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标顺时针移动，则在获取到一个最新两个电磁信号对应的坐标[(x An，y An)，(x Bn，y Bn)]时，可分别确认一个电磁信号对应的最新坐标与该最新坐标的前一坐标，如(x An，y An)与(x An-1，y An-1)对应坐标值之差的绝对值是否均小于第四预设阈值，若是，则保存[(x An，y An)，(x Bn，y Bn)]至第三预设列表，且将第三个数加1，并确认第三个数是否达到第三预设个数，若达到第三预设个数，则从第三预设列表选取该电磁信号对应的坐标(x An，y An)中的任一坐标作为坐标原点，对第三预设列表中的另一个电磁信号对应的所有坐标(x Bn，y Bn)进行坐标变换，并确认进行坐标变换后的坐标(x Bn’，y Bn’)是否满足：当x Bn-1’和x Bn’均大于0时，y Bn’大于y Bn-1’，或者当x Bn-1’和x Bn’均小于0时，y Bn’小于y Bn-1’，或者当y Bn-1’和y Bn’均大于0时，x Bn’小于x Bn-1’，或者当y Bn-1’和y Bn’均小于0时，x Bn’大于x Bn-1’，若是，则确定一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标逆时针移动。
步骤230、根据预设的控制指令列表确认变化状态对应的控制指令，并将控制指令发送到智能终端。
获取电磁信号对应的坐标的变化状态后，则根据预设的控制指令列表确认变化状态对应的控制指令，并将控制指令发送到智能终端，以进一步对智能终端进行控制。
需要说明的是，预设的控制指令列表中保存的变化状态与控制指令之间的对应关系，可根据实际情况进行设定，本发明对此不进行限定。
优选的，控制指令包括：当前页面关闭指令、向前翻页指令、向后翻页指令和轨迹擦除触发指令中的至少一个。
可选的，控制指令还可包括：向前切换应用指令和向后切换应用指令。
在一个具体的实施例中，预设的控制指令列表中与变化状态为电磁信号对应的坐标维持不变达到预设时长对应的控制指令为当前页面关闭指令，与变化状态为两个电磁信号对应的坐标顺时针移动对应的控制指令为向前翻页指令，与变化状态为两个电磁信号对应的坐标逆时针移动对应的控制指令为向后翻页指令，与变化状态为两个电磁信号对应的坐标平行移动对应的控制指令为轨迹擦除触发指令，与变化状态为一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标逆时针移动对应的控制指令为向前切换应用指令，与变化状态为一个电磁信号对应的坐标不动，另一个电磁信号对应的坐标顺时针移动对应的控制指令为向后切换应用指令。
示例性的，若智能终端接收到当前页面关闭指令，则智能终端将可将当前前台开启的应用软件(如电子白板软件)进行保存后关闭，若智能终端接收到向前翻页指令，则智能终端可将当前前台开启的应用软件进行向前翻页，若智能终端接收到向后翻页指令，则智能终端可将当前前台开启的应用软件进行向后翻页，若智能终端接收到轨迹擦除触发指令，则智能终端可调用当前前台开启的应用软件中的橡皮擦功能，若智能终端接收到向前切换应用指令，则智能终端可将当前前台开启的应用软件切换为后台开启的应用软件中的最后一个应用软件(即最早开启的应用软件)或者切换为预设应用软件，若智能终端接收到向后切换应用指令，则智能终端可将当前前台开启的应用软件切换为当前后台开启的应用软件中当前前台开启的应用软件对应的下一应用软件或者预设应 用软件。
由此实现，当用户需与智能终端进行交互操作时，用户只需将智能笔的第一电磁发射模组和第二电磁发射模组同时靠近电磁感应板，并控制两个电磁信号对应的坐标按一定的变化状态进行变化即可，简单便捷。
优选的，若根据预设的控制指令列表确认变化状态对应的控制指令为轨迹擦除触发指令，则将控制指令发送到智能终端之后，还包括：
若确认通过电磁感应板接收到一个电磁信号，则获取电磁信号对应的坐标移动轨迹，以确认待擦除的轨迹。
实际上，擦除的操作方式至少有两种，一种是实施例一中所说如果设定频率A进行书写，频率B进行擦除，则将检测到频率A对应的轨迹进行书写显示，将检测到频率B对应的轨迹的设定范围内显示的内容取消显示即可。另一种是如果频率A和频率B均可进行书写，那么擦除的交互过程则有所变化。
具体的，为了保证电磁笔的正常书写功能，则在根据预设的控制指令列表确认变化状态对应的控制指令为轨迹擦除触发指令，并将控制指令发送到智能终端之后，若仅通过电磁感应板接收到一个某一频率的电磁信号(可以是第二电磁发射模组发射的电磁信号，也可以是第二电磁发射模组发射的电磁信号)，则获取该电磁信号对应的坐标移动轨迹，并将获取的坐标移动轨迹作为待擦除的轨迹发送至智能终端，则智能终端在接收到待擦除的轨迹后，对待擦除的轨迹进行擦除，完成对轨迹擦除触发指令的具体响应。
优选的，若确认通过电磁感应板接收到一个电磁信号，则获取电磁信号对应的坐标移动轨迹，以确认待擦除的轨迹之后，还包括：
若通过电磁感应板接收到两个电磁信号，则向智能终端发送撤销轨迹擦除 指令的控制指令。
具体的，在若确认通过电磁感应板接收到一个电磁信号，则获取电磁信号对应的坐标移动轨迹之后，若通过电磁感应板再次接收到两个电磁信号，则向智能终端发送撤销轨迹擦除指令的控制指令，智能终端接收到撤销轨迹擦除指令的控制指令，则停止调用橡皮擦功能。
示例性的，在将控制指令发送到智能终端之后，若通过电磁感应板接收到一个频率的电磁信号(可以是第一电磁发射模组发射的电磁信号，也可以是第二电磁发射模组发射的电磁信号)，则可将获取的该电磁信号的坐标确定为书写轨迹，并将书写轨迹发送至智能终端以供智能终端进行保存或显示，同时可将本次与获取电磁信号对应的坐标的变化状态相关的数据进行清除，如在确认两个电磁信号对应的坐标顺时针移动中第一预设列表保存的坐标数据以及在确认两个电磁信号对应的坐标平行移动中获取的斜率等数据，以保证下次可准确获取电磁信号对应的坐标的变化状态。
在一个具体的实施例中，本实施例提供的方法的执行主体可为一安装有电磁感应板的电子设备(如电子笔记本)，该电子设备与至少一个智能终端通过蓝牙或网络建立通信连接，当该电子设备通过电磁感应板接收到电磁信号时，电子设备可获取电磁信号对应的坐标，进而实现当电子设备通过电磁感应板同时接收到两个电磁信号时，获取电磁信号对应的坐标的变化状态，并根据预设的控制指令列表确认变化状态对应的控制指令，将控制指令通过蓝牙或网络发送到智能终端。
