可选地，在一些实施例中，条件1还可以包括：平板20和手机10之间的距离小于或等于第五阈值(如第五阈值可以为40cm)。
示例性地，平板20可检测手机10发送的信号，并基于手机10发送的信号，确定平板20与目标设备之间的距离是否小于或等于第五阈值。
例如，平板20可向手机10发送探测信号，手机10在收到探测信号之后，向平板20发送响应信号。这样，平板20在接收到手机10发送的响应信号之后，根据响应信号的强度，确定平板20与目标设备之间的距离是否小于或等于第五阈值。
本申请实施例对目标设备的数量不作限定。为了方便描述，以下均以目标设备为手机10为例，对方法200进行描述。
在平板20确定不满足条件1的情况下，平板20不执行任何步骤。在平板20确定满足条件1的情况下，平板20执行S230。
可选地，在一些实施例中，平板20还可以根据S220，确定是否执行S230。
S220，平板20确定手机10是否满足条件2。
条件2包括以下至少一项：手机10显示有输入框、手机10的显示界面的底部显示有输入框、或手机10的显示界面为目标应用程序的显示界面。其中，目标应用程序可以包括聊天类应用程序、搜索类应用程序(如浏览器类应用程序)、办公类应用程序、学习类应用程序等。
当条件2包括手机10显示有输入框、手机10的显示界面的底部显示有输入框、或手机10的显示界面为目标应用程序的显示界面中的至少两项时，平板20对该至少两项的先后判断顺序不作限定。
在一个示例中，如图8所示，S220包括S221和S222。在另一个示例中，S220仅包括S222，不包括S221。此时，手机10可以周期性地执行S222。下面详细介绍S221和S222。
S221，平板20可以向手机10发送查询信息1。相应地，手机10接收来自平板20发送的查询信息1。其中，查询信息1用于查询：手机10的显示界面上是否显示输入框、手机10的显示界面的底部是否显示有输入框、或手机10的显示界面是否为目标应用程序的显示界面。
示例性地，手机10可以根据手机10的显示界面上的布局(layout)查看是否有输入(input)控件， 若手机10的显示界面上的布局中有输入控件，则手机10的显示界面上包括文本输入框；若手机10的显示界面上的布局中没有输入控件，则手机10的显示界面上不包括文本输入框。
示例性地，手机10可以根据手机10的显示界面上的布局(layout)查看是否有输入控件，并确定输入控件是否在手机10的显示界面的底部，若手机10的显示界面上的布局中有输入控件、且输入控件在手机10的显示界面的底部，则手机10的显示界面上包括文本输入框；若手机10的显示界面上的布局中没有输入控件，则手机10的显示界面上不包括文本输入框。
示例性地，手机10可以根据手机10的显示界面上的布局(layout)查看手机10的显示界面对应的应用程序的名称，并确定应用程序的名称是否为目标应用程序的名称，若手应用程序的名称不是目标应用程序的名称，则手机10的显示界面不是目标应用程序的显示界面；若手机10的显示界面上的布局中没有输入控件，则手机10的显示界面为目标应用程序的显示界面。
S222，手机10向平板20发送响应信息1。相应地，平板20接收来自手机10发送的响应信息1。其中，响应信息1用于指示：手机10的显示界面上是否显示输入框、手机10的显示界面的底部是否显示有输入框、或手机10的显示界面是否为目标应用程序的显示界面。
当响应信息1用于指示：手机10的显示界面上未显示输入框、手机10的显示界面的底部未显示有输入框、或手机10的显示界面不是目标应用程序的显示界面时，平板20确定不执行S230。当响应信息1用于指示：手机10的显示界面上显示有输入框、手机10的显示界面的底部显示有输入框、或手机10的显示界面是目标应用程序的显示界面时，平板20确定执行S230。
当平板20满足条件2的情况下，平板20才执行S230，即平板20才获取用户的视线，这样，可以降低平板20的功耗。
S230，平板20获取用户的视线。
在一个示例中，若平板20上设置有摄像头，此时，平板20可以开启摄像头，通过摄像头采集用户的图像，并根据所采集的用户的图像，来获取用户的视线。
例如，首先，平板20可以根据采集的用户的图像，得到用户瞳孔的位置。其次，平板20根据用户瞳孔的位置，得到用户瞳孔的方向。最后，平板20根据用户瞳孔的方向，获取用户的视线。
在另一个示例中，平板20也可以从其他可采集用户的图像的设备获取用户的图像，并根据获取的用户的图像，来获取用户的视线。
例如，手机10上设置有摄像头，手机10可以开启摄像头，通过手机10的摄像头采集用户的图像，并将采集的用户的图像传给平板20，从而平板20根据手机10采集的用户的图像，来获取用户的视线。
S240，平板20确定用户的视线不在平板20上。
示例性的，若S230获取的用户的视线与平板20的屏幕的延展面有交点，那么平板20确定用户的视线不在平板20上。
例如，若用户的视线与平板20的屏幕向左/右/上/下延展的延展面有交点，那么，用户的视线不在平板20上，且用户的视线是看向平板20的屏幕的左边/右边/上边/下边。
S250，平板20确定用户的视线是否在手机10上。
示例性地，平板20可以先确定手机10相对于平板20的位置，然后，当用户的视线和手机10相对于平板20的位置一致，平板20可确定用户的视线在手机10上；当用户的视线和手机10相对于平板20的位置不一致，平板20可确定用户的视线不在手机10上。
用户的视线和手机10相对于平板20的位置一致可以理解为：手机10在平板20的左边/右边/上边/下边，用户的视线是看向平板20的屏幕的左边/右边/上边/下边。
在一个示例中，平板20可通过检测手机10发送的信号，并基于手机10发送的信号，确定手机10相对于平板20的位置。
例如，若平板20的左右位置设置有麦克风，当平板20的左边/右边的麦克风先检测手机10发送的信号，那么，平板20可确定手机10在平板20的左边/右边。
又例如，若平板20的上下位置设置有麦克风，当平板20的上边/下边的麦克风先检测手机10发送的信号，那么，平板20可确定手机10在平板20的上边/下边。
在另一个示例中，若用户通过平板20设置了手机10相对于平板20的位置，那么，平板20可通过用户的设置，获取手机10相对于平板20的位置。
可选地，在一些实施例中，平板20在执行S250的过程中，不仅要考虑用户的视线和手机10相对于 平板20的位置，还需要考虑用户的视线相对于平板20而言是否在目标范围内。当用户的视线和手机10相对于平板20的位置一致，且用户的视线相对于平板20而言在目标范围内，则平板20可确定用户的视线在手机10上。
示例性地，目标范围可以理解为与平板20的法线之间的夹角小于或等于目标角度。例如，目标角度可以为30°或45度等。
若平板20确定用户的视线不在手机10上，此时，平板20不需要执行S260。此时，方法200仅包括S210至S250。
若平板20确定用户的视线在手机10上，平板20需要执行S260。
S260，平板20确定键盘30的焦点在平板20上还是在手机10。
若平板20确定键盘30的焦点不在平板20上而在手机10上，此时由于用户的视线也在手机10上，因此，平板20不需要切换键盘30的焦点，即平板不需要执行S270。此时，方法200仅包括S210至S260。
若平板20确定键盘30的焦点在平板20上而不在手机10上，而由于此时用户的视线是手机10上，因此，平板20需要将键盘30的焦点切换至用户的视线所在的手机10上，即平板20需要执行S270。
可选地，在S270之前，若平板20已确定手机10显示有输入框，平板20在S260之后，可直接执行S270。在S270之前，若平板20未确定手机10是否显示有输入框，那么，在S260之后，平板20需要确定手机10是否显示有输入框，并在手机10显示有输入框的情况下，才去执行S270。
关于平板20如何确定手机10是否显示有输入框可参考上文S221和S222的相关描述，这里不再赘述。
S270，平板20向手机10发送指示信息1。相应地，手机10接收来自平板20的指示信息1。
其中，指示信息1用于指示键盘30上的输入可切换至手机10的文本输入框。
S280，手机10输出提示信息1。
其中，提示信息1用于指示用户可将键盘30的焦点切换至手机10的文本输入框。
示例性地，手机10可以显示提示信息1或播放提示信息1。
本申请实施例对提示信息1的具体显示形式和显示位置不作限定。
在一个示例中，提示信息1可以仅指示用户可将键盘30的焦点切换至手机10的文本输入框。
例如，如图4中的(b)所示，提示信息1可以包括图标1017和光标1018，图标1017显示在文本输入框1014的附近，光标1018显示在文本输入框1014中。
又例如，如图5中的(b)所示，提示信息1可以包括图标1113和光标1114，图标1113显示在网址输入框1111的附近，光标1114显示在网址输入框1111中。
在另一个示例中，提示信息1可以指示在键盘30上输入操作1时，可将键盘30的焦点切换至手机10的文本输入框。
例如，如图4中的(b)所示，提示信息1可以包括图标1017、“点击回车进行输入”的文本信息、光标1018，图标1017和“点击回车进行输入”的文本信息显示在文本输入框1014的附近，光标1018显示在文本输入框1014中。
又例如，如图5中的(b)所示，提示信息1可以包括图标1113和“点击回车进行输入”的文本信息、光标1114，图标1113和“点击回车进行输入”的文本信息显示在网址输入框1111的附近，光标1114显示在网址输入框1111中。
用户在看到手机10中的提示信息1后，用户可在键盘30上进行操作1，便可将键盘30的焦点切换至手机10的文本输入框。此时，键盘30执行S290。

第二提示信息和第一提示信息的显示位置相同，第二提示信息和第一提示信息的显示效果不同。若第四提示信息和第一提示信息的显示效果不同，那么此时第二提示信息和第四提示信息的显示效果可以相同，也可以不同。
例如，第二光标和第一光标的显示位置相同，但是第二光标和第一光标的显示效果不同。又例如，第二图标和第一图标的显示位置相同，但是第二图标和第一图标的显示效果不同。又例如，第二外框和第一外框的显示相同，但是第二外框和第一外框的显示效果不同。
关于第二光标、第二图标、第二文本信息的描述可分别参考上文图4中的(c)中关于光标1020、图标1019、“输入中…”的文本信息的相关描述，或者，关于第二光标、第二图标、第二文本信息的描述可分别参考上文图5中的(c)中关于光标1116、图标1115、“输入中…”的文本信息的相关描述这里不再赘述。
可选地，在一些实施例中，在S560之后，输入设备便可将用户输入的信息通过第一电子设备传给第二电子设备，以便第二电子设备显示在其显示界面上。也就是说，用户通过输入设备和第一电子设备，便可在第二电子设备上输入信息。
在该实施例中，具体地，在S560之后，方法500还可以包括：S570，输入设备响应于获取到用户的第一输入信息，并向第一电子设备发送第一输入信息；S580，第一电子设备响应于第一输入信息，向第二电子设备转发第一输入信息；S590，第二电子设备，还用于响应于第一输入信息，在第一输入框显示第一输入信息。
可选地，在一些实施例中，在S560之前，若第二电子设备上的第一输入框中显示有默认的文字，在S560之后，第二电子设备上的第一输入框中不再显示该默认的文字。
例如，如图5中的(c)所示，手机10上的文本输入框1112中显示有“搜索词”(默认的文字的一例)，那么，在S550之后，如图5中的(d)所示，手机10上的文本输入框1112中不再显示“搜索词”。
可选地，在一些实施例中，在S560之后，若第二电子设备上不再显示有第一输入框，第一电子设备可以直接再将输入设备的焦点切换回第一电子设备。这样，用户通过输入设备便可在第一电子设备上输入信息。
在该实施例中，具体地，在S560之后，方法500还可以包括：S591，第二电子设备确定第二电子设备上不再显示有第一输入框，控制第二电子设备处于失去输入设备的焦点的状态，并向第一电子设备发送第四指示信息，第四指示信息用于指示第一电子设备可获取输入设备的焦点；S592，第一电子设备响应于第四指示信息，控制第一电子设备处于获取输入设备的焦点的状态。
通过方法500，当用户的视线在第二电子设备上、输入设备的焦点在第一电子设备上、以及第二电子设备上显示有输入框时，可以向第二电子设备发送第一指示信息。然后，第二电子设备在接收到第一指示信息后，在第一输入框中直接显示输入设备的焦点，或者输出第一提示信息，来提示切换输入设备的焦点的操作。进而，用户可根据第一提示信息，通过输入设备将输入设备的焦点切换至用户的视线所在 的第二电子设备的输入框中。这样，用户通过简单的操作，便可以实现将输入设备的焦点由第一电子设备跨设备的切换至第二电子设备，有助于提升用户切换输入设备的焦点时的用户体验。
需要说明的是，第一电子设备还可以执行上述方法500中未描述的其他步骤，该其他步骤可以参考图8中所述的平板20执行的步骤，这里不再赘述。此外，第二电子设备也还可以执行上述方法500中未描述的其他步骤，该其他步骤可以参考图8中所述的手机10执行的步骤，这里不再赘述。
图11为本申请实施例提供的一例跨设备切换焦点的方法600的示意性流程图。
如图11所示，方法600包括S610。下面，详细介绍S610。
S610，当满足第一条件时，第一电子设备在第一电子设备上显示输入设备的焦点，或者，输出第三提示信息。
其中，第一条件包括用户注视的区域属于第一电子设备所在的区域或第二电子设备上未显示输入框。
第一电子设备上不存在输入设备的焦点，第二电子设备上存在输入设备的焦点，即输入设备的焦点在第二电子设备上。
可选地，在S610之前，第一电子设备可以执行S620。
S620，第一电子设备确定是否满足第一条件以及输入设备的焦点在第二电子设备上。
本申请实施例对第一电子设备确定满足第一条件以及输入设备的焦点在第二电子设备上之间的顺序不作限定。
S620的过程和S530的过程类似，只需将上述S532a和S533a(或者S531b和S532b)中所示的第一确认信息用第二指示信息替代即可。其中，第二指示信息用于指示第二电子设备上是否显示有输入框。因此，关于S620的描述可以参考S530的相关描述，这里不再赘述。
可选地，当输入设备的焦点在第二电子设备上，第二电子设备还可以输出第二提示信息。关于该第二提示信息的描述可以参考上文图10中的相关描述，这里不再赘述。
需要说明的是，当第一条件包括用户注视的区域属于第一电子设备所在的区域时，那么，无论第二电子设备上是否显示有输入框，第一电子设备都可在第一电子设备上显示输入设备的焦点或者输出第三提示信息。也就是说，S610中，可以无需考虑第二电子设备上是否显示有输入框的情况，只需考虑用户注视的区域。当然，S610中也可以考虑第二电子设备上是否显示有输入框，并在第二电子设备上未显示有输入框、且用户注视的区域属于第一电子设备所在的区域的情况下，第一电子设备才在第一电子设备上显示输入设备的焦点或者输出第三提示信息。
当第一条件包括第二电子设备上未显示有输入框时，那么，无论用户注视的区域是否属于第一电子设备所在的区域，第一电子设备都可在第一电子设备上显示输入设备的焦点或者输出第三提示信息，也就是说，S610中，可以无需考虑用户注视的区域的情况，只需考虑第二电子设备上是否显示有输入框。当然，S610中也可以考虑用户注视的区域，并在用户注视的区域属于第一电子设备所在的区域、且第二电子设备上未显示有输入框的情况下，第一电子设备才在第一电子设备上显示输入设备的焦点或者输出第三提示信息。
在一个示例中，第三提示信息用于提示用户可将输入设备的焦点切换至第一电子设备。在另一个示例中，第三提示信息还用于提示用户在输入设备上输入第一操作，可将输入设备的焦点切换至第一电子设备。
示例性地，第一电子设备可以显示第三提示信息或播放第三提示信息。
示例性地，第三提示信息可以包括以下至少一项：第三光标、第三图标、第三文本信息、第三外框。其中，该第三光标显示在第一电子设备上输入设备的焦点待切入的位置，第三图标用于指示用于切换输入设备的焦点的设备(即输入设备)，第三文本信息用于指示第一操作，第三外框包围第二电子设备上输入设备的焦点待切入的输入框。
例如，第三图标可以是如图6中的(b)所示的图标2111，第三文本信息可以是如图6中的(b)所示的“点击回车进行输入”的文本信息。
又例如，第三图标可以是如图7中的(b)所示的图标2213，第三文本信息可以是如图7中的(b)所示的“点击回车进行输入”的文本信息。
关于第三图标、第三文本信息的描述可分别参考上文如图6中的(b)中关于图标2111、“点击回车进行输入”的文本信息的相关描述，或者，关于第三图标、第三文本信息的描述可分别参考上文如图7中的(b)中关于图标2213、“点击回车进行输入”的文本信息的相关描述，这里不再赘述。
需要说明的是，若第三提示信息包括第三图标和第三文本信息，那么，第三提示信息还用于提示用户在输入设备上输入第一操作，可将输入设备的焦点切换至第一电子设备。
在一个示例中，若第一电子设备上仅显示有一个输入框(即第三输入框)，当S610中第一电子设备是在第一电子设备上显示输入设备的焦点，那么，该输入设备的焦点可以显示在第三输入框中。当S610中第一电子设备是输出第三提示信息，那么，该第三提示信息可以用于提示用户可将输入设备的焦点切换至第三输入框，该第三提示信息可以显示在第三目标位置，第三目标位置与第三输入框之间的距离小于或等于第三阈值。也就是说，第三提示信息显示在第三输入框的附近，这样，用户便可以直观地获知输入设备的焦点待切换的输入框。
例如，如图6中的(b)所示，第三提示信息显示在“XXX”文本信息的附近(第三目标位置的一例)。
在另一示例中，若第一电子设备上显示有多个输入框，如多个输入框包括第三输入框和第四输入框，当S610中第一电子设备是在第一电子设备上显示输入设备的焦点，那么，该输入设备的焦点可以显示在第四输入框中。当S610中第一电子设备是输出第三提示信息，那么，该第三提示信息可以显示在第四目标位置，第四目标位置与第四输入框之间的距离小于或等于第四阈值。也就是说，第三提示信息显示在第四输入框的附近，这样，用户便可以直观地获知输入设备的焦点待切换的输入框。若用户想要调整第一电子设备上输入设备的焦点待切换的输入框，用户可在输入设备上进行第二操作，这样，输入设备响应于检测到第二操作，向第一电子设备发送第二切换信息，第二切换信息用于指示将第三提示信息的显示位置由第四目标位置调整至第三目标位置，第三目标位置与第三输入框之间的距离小于或等于第三阈值；第一电子设备响应于第二切换信息，将第三提示信息的显示位置由第四目标位置调整至第三目标位置。
示例性地，第二操作可以包括点击Tab键的操作。
例如，图7中的(b)所示，平板20显示的输入框包括网址输入框2211和搜索词输入框2212，第三提示信息一开始显示在网址输入框2211的附近，此时，键盘30的焦点可切换至平板20的网址输入框2211。若用户不想将键盘30的焦点切换至平板20的网址输入框2211，想要将键盘30的焦点切换至平板20的搜索词输入框2212，用户可在键盘30上点击Tab键后，键盘30可将平板20上显示的第三提示信息的位置调至搜索词输入框2212，此时，键盘30的焦点可切换至平板20的搜索词输入框2212。
其中，第四输入框为第一电子设备最近一次输入焦点所在的输入框；或者，第四输入框为第一电子设备的显示界面上的第一个输入框。
示例性地，第一电子设备中存储有第一电子设备每次输入焦点所在位置，这样，第一二电子设备默认将第三提示信息显示在第一电子设备最近一次(上一次)输入焦点所在的第四输入框的附近。
应理解，第一电子设备的显示界面上的第一个输入框可以理解为：第一电子设备的显示界面上的输入框中，距离第一电子设备的显示界面的上边缘和左边缘最近的输入框即为第一个输入框。
需要说明的是，在S610中，若第一电子设备显示输入设备的焦点，用户可以通过输入设备操作第一电子设备或在第一电子设备上输入信息。若第一电子设备上输出第三提示信息，用户还不能通过输入设备操作第一电子设备或在第一电子设备上输入信息。
示例性地，在S610中，若第一电子设备在第一电子设备上显示输入设备的焦点，那么，在S610之前，方法600还可以包括S630至S650；若第一电子设备输出第三提示信息，那么，在S610之后，方法600还可以包括S630至S650。下面详细介绍S630至S650。
S630，输入设备响应于检测到第一操作，向第一电子设备发送第四切换信息。相应地，第一电子设备接收来自输入设备的第四切换信息。
其中，第四切换信息用于指示将输入设备的焦点切换至第一电子设备。
示例性地，第一操作可以是点击回车键的操作。
S640，第一电子设备响应于第四切换信息，控制第一电子设备处于获取输入设备的焦点的状态，并向第二电子设备发送第五指示信息。相应地，第二电子设备接收来自第一电子设备的第五指示信息。
示例性地，第五指示信息可以用于指示第一电子设备处于获取输入设备的焦点的状态。
需要说明的是，本申请实施例对第一电子设备控制第一电子设备处于获取输入设备的焦点的状态的步骤和第一电子设备向第二电子设备发送第五指示信息的步骤之间的执行顺序不作限定。
S650，第二电子设备响应于第五指示信息，控制第二电子设备处于失去输入设备的焦点的状态。
可选地，在一些实施例中，在S650之后，第二电子设备不再显示第二提示信息。
可选地，在一些实施例中，在S640之后，第一电子设备还可以输出第四提示信息。其中，第四提示信息用于指示用户通过输入设备可在第一电子设备上输入信息。
示例性地，第一电子设备可以显示第四提示信息或播放第四提示信息。
示例性地，第四提示信息可以包括以下至少一项：第四光标、第四图标、第四文本信息、第四外框。其中，该第四光标显示在第三输入框中，第四图标用于指示输入设备，第四文本信息用于指示用户可在第三输入框中输入信息，第四外框包围第三输入框。
例如，第四图标可以是如图6中的(c)所示的图标2112，第四文本信息可以是如图6中的(c)所示的“输入中…”的文本信息。
又例如，第四图标可以是如图7中的(d)所示的图标2214，第四文本信息可以是如图7中的(d)所示的“输入中…”的文本信息，第四外框可以是如图7中的(d)所示的外框2215。
第四提示信息和第三提示信息的显示位置相同，第四提示信息和第三提示信息的显示效果不同。此时，第四提示信息和第二提示信息的显示效果可以相同，也可以不同。
例如，第四光标和第三光标的显示位置相同，但是第四光标和第三光标的显示效果不同。又例如，第四图标和第三图标的显示位置相同，但是第四图标和第三图标的显示效果不同。又例如，第四外框和第三外框的显示相同，但是第四外框和第三外框的显示效果不同。
关于第四图标、第四文本信息的描述可分别参考上文图6中的(c)中关于图标2112、“输入中…”的文本信息的相关描述，或者，关于第四图标、第四文本信息、第四外框的描述可分别参考上文图7中的(d)中关于图标2214、“输入中…”的文本信息、外框2215的相关描述这里不再赘述。
可选地，在一些实施例中，在S640之前，若第一电子设备上的第三输入框中显示有默认的文字，在S640之后，第一电子设备上的第三输入框中不再显示该默认的文字。
例如，如图7中的(c)所示，平板20上的搜索词输入框2212中显示有“搜索词”(默认的文字的一例)，那么，在S640之后，如图7中的(d)所示，平板20上的搜索词输入框2212中不再显示“搜索词”。
可选地，在一些实施例中，在S640之后，用户通过输入设备便可在第一电子设备上输入信息。
在该实施例中，具体地，在S640之后，方法600还可以包括：S660，输入设备响应于获取到用户的第二输入信息，并向第一电子设备发送第二输入信息；S670，第一电子设备响应于第二输入信息，显示第二输入信息。
通过方法600，当输入设备的焦点在第二电子设备上、以及用户的视线在第一电子设备上或第二电子设备上没有输入框时，第一电子设备可以在第一电子设备上显示输入设备的焦点，或者输出第三提示信息。进而，用户可根据第三提示信息，通过输入设备将输入设备的焦点切换至用户的视线所在的第一电子设备上。这样，用户通过简单的操作，便可以实现将输入设备的焦点由第二电子设备跨设备的切换至第一电子设备，有助于提升用户切换输入设备的焦点时的用户体验。
需要说明的是，第一电子设备还可以执行上述方法600中未描述的其他步骤，该其他步骤可以参考图9中所述的平板20执行的步骤，这里不再赘述。第二电子设备也还可以执行上述方法600中未描述的其他步骤，该其他步骤可以参考图9中所述的手机10执行的步骤，这里不再赘述。
此外，无论是图10所示的方法500，还是图11所示的方法600，当第一电子设备和第二电子设备登录有同一账号，第一电子设备与第二电子设备可通过云端传输信息(如上文所述的第一查询信息，第一确认信息、第二查询信息，第二确认信息、第一指示信息、第一输入信息、第二输入信息等)。当第一电子设备和第二电子设备连接，第一电子设备与第二电子设备可通过两者建立的连接方式传输信息(如上文所述的第一查询信息，第一确认信息、第二查询信息，第二确认信息、第一指示信息、第一输入信息、第二输入信息等)。
图10和图11中所述的输入设备的焦点可理解为用户通过输入设备输入的信息显示的位置。例如，输入设备的焦点在第一电子设备上，即用户通过输入设备可在第一电子设备上输入信息。又例如，输入设备的焦点在第二电子设备的输入框上，即用户通过输入设备可在第二电子设备的输入框中输入信息。
下面，结合图12对本申请实施例提供的跨设备切换焦点的装置进行描述。
