具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面，但是除非特别指出，不必按比例绘 制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本公开，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本公开同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本公开的主旨。
首先，对本公开涉及的应用场景进行介绍。请参考图1，其示出了本公开一个示例性实施例提供的终端设备10的结构示意图。
可选地，该终端设备10为便携式设备或者可穿戴式设备。
该终端设备10包括但不限于手机、平板电脑、电子书阅读器、动态影像专家压缩标准音频层面3(Moving Picture Experts Group Audio Layer III，MP3)播放器、动态影像专家压缩标准音频层面4(Moving Picture Experts Group Audio Layer IV，MP4)播放器、膝上型便携计算机、智能手表、智能手环、智能等等。本实施例对此不加以限定。
终端设备10的设备状态包括熄屏休眠状态、关闭状态和亮屏唤醒状态中的任意一种。
该终端设备10包括麦克风12和扬声器14。其中，扬声器14也称为喇叭。
由于麦克风12在开启状态下会产生较大功耗，而扬声器14本身是不需要供电的，本公开实施例通过在终端设备10处于熄屏休眠状态时不必开启麦克风12，即熄屏休眠状态下终端设备10的麦克风12处于关闭状态。终端设备10通过扬声器14获取第一电信号，第一电信号为扬声器14在接收到交互对象的吹气时所产生的电信号；当第一电信号满足第一预设条件时触发第一指定事件即预先设置的人机交互事件，在更低功耗下实现了非接触式人机交互。与相关技术中接触式人机交互(如按键，指纹等)可以解放双手，与相关技术中采用麦克风进行语音唤醒可以节省200～300uA左右的功耗，这个数量级在终端设备(比如手机、手表、手环)上是非常有意义的。
下面，采用几个示例性的实施例对本公开提供的非接触式人机交互方法进行说明。
请参考图2，其示出了本公开一个示例性实施例提供的非接触式人机交互方法的流程图，本实施 例以该方法用于图1所示的终端设备中来举例说明。该方法包括以下几个步骤。
步骤201，在终端设备处于熄屏休眠状态时，通过终端设备的扬声器获取第一电信号，第一电信号为扬声器在接收到交互对象的吹气时所产生的电信号。
其中，熄屏休眠状态下终端设备的麦克风处于关闭状态。
在终端设备处于熄屏休眠状态的情况下，麦克风处于关闭状态，交互对象向终端设备的扬声器吹气，对应的终端设备通过扬声器接收交互对象的吹气，产生对应的电信号即第一电信号。
可选地，交互对象为终端设备的持有者或者拥有者，比如，交互对象为人。本公开实施例对此不加以限定。
示意性的，交互对象向终端设备的扬声器吹气，扬声器的振膜会上下振动，相当于附在振膜上的线圈在扬声器磁钢形成的磁场中做切割运动，从而使扬声器两端产生电信号即第一电信号，第一电信号经过放大处理后可以用来实现交互对象与终端设备之间的人机交互。
步骤202，当第一电信号满足第一预设条件时触发第一指定事件，第一指定事件为预先设置的人机交互事件。
终端设备判断第一电信号是否满足第一预设条件，若第一电信号满足第一预设条件，则终端设备触发第一指定事件。若第一电信号不满足第一预设条件，则结束进程。
第一预设条件为预先设置的用于触发第一指定事件的条件。比如，第一预设条件为第一电信号经放大处理后大于预设门限阈值。其中，预设门限阈值是默认设置的，或者是自定义设置的。本实施例对第一预设条件的设置方式不加以限定。
第一指定事件为预先设置的人机交互事件。人机交互事件为人与终端设备之间使用某种对话语言，以一定的交互方式，为完成确定任务的人与计算机之间的信息交换的事件。
综上所述，由于麦克风在开启状态下会产生较大功耗，而扬声器本身是不需要供电的，本公开实施例通过在终端设备处于熄屏休眠状态时，通过终端设备的扬声器获取第一电信号，第一电信号为扬声器在接收到交互对象的吹气时所产生的电信号；当第一电信号满足第一预设条件时触发第一指定事件，第一指定事件为预先设置的人机交互事件，其中熄屏休眠状态下终端设备的麦克风处于关闭状态；使得在终端设备处于熄屏休眠状态时不必开启麦克风，交互对象向扬声器吹气即可触发预先设置的人 机交互事件，有效地降低了终端设备在熄屏休眠状态下的功耗。
请参考图3，其示出了本公开另一个示例性实施例提供的非接触式人机交互方法的流程图，本实施例以该方法用于图1所示的终端设备中来举例说明。该方法包括以下几个步骤。
步骤301，在终端设备处于熄屏休眠状态时，通过终端设备的扬声器获取第一电信号，第一电信号为扬声器在接收到交互对象的吹气时所产生的电信号。
在终端设备处于熄屏休眠状态时，终端设备通过扬声器在接收到交互对象的吹气时产生电信号即第一电信号。第一电信号为在终端设备处于熄屏休眠状态时通过扬声器获取到的电信号。
需要说明的是，终端设备通过扬声器获取第一电信号的过程可参考上述实施例中的相关细节，在此不再赘述。
步骤302，通过放大器将第一电信号的幅度放大至预设幅度值。
终端设备通过放大器对第一电信号进行放大处理，即将第一电信号的幅度放大至预设幅度值。放大器也称可编程放大器，用于对第一电信号进行放大处理。
其中，预设幅度值为默认设置的，或者是自定义设置的。本实施例对此不加以限定。
步骤303，当放大后的第一电信号的参数大于预设门限阈值时触发第一指定事件。
终端设备判断放大后的第一电信号的参数是否大于预设门限阈值，若放大后的第一电信号的参数大于预设门限阈值则表示满足第一预设条件，触发第一指定事件；否则，结束进程。
由于终端设备通过对扬声器吹气产生的电信号可以达到毫伏级别大小，经过放大器使电信号达到一定幅度后进行门限判断，环境噪音对喇叭振膜几乎没有影响，即使是较大的环境噪音仍然与吹气所产生的信号有较大差距，这里的门限判决可以保证环境噪音无法触发指定事件。
可选地，放大后的第一电信号的参数用于指示放大后的第一电信号的大小，放大后的第一电信号的参数包括放大后的第一电信号的峰值或者有效值或者平均值。本公开实施例对此不加以限定。
可选的，第一指定事件包括亮屏事件、解锁事件、语音播报事件、语音识别功能启动事件中的任意一种。
其中，亮屏事件为将终端设备的屏幕状态从熄屏状态切换为亮屏状态的事件。解锁事件也称亮屏 并解锁事件，解锁事件为将终端设备的屏幕状态从熄屏状态切换为亮屏状态并解锁屏幕的事件。语音播报事件为通过终端设备的扬声器以语音方式播报预设内容的事件。语音识别功能启动事件为将终端设备的麦克风从关闭状态切换为开启状态的事件。本公开实施例对第一指定事件的类型不加以限定。
步骤304，在终端设备处于亮屏唤醒状态且目标应用程序处于前台运行时，通过扬声器获取第二电信号。
在终端设备处于亮屏唤醒状态的情况下，麦克风处于关闭或者开启状态，目标应用程序处于前台运行的过程中，终端设备通过扬声器在接收到交互对象的吹气时产生电信号即第二电信号。第二电信号为在终端设备处于亮屏唤醒状态且目标应用程序处于前台运行时通过扬声器获取到的电信号。
其中，目标应用程序为预先设置的应用程序。
步骤305，当第二电信号满足第二预设条件时触发第二指定事件，第二指定事件为预先设置的目标应用程序中的人机交互事件。
第二预设条件为预先设置的用于触发第二指定事件的条件。比如，第二预设条件为第二电信号经放大处理后大于预设门限阈值。其中，预设门限阈值是默认设置的，或者是自定义设置的。本实施例对第二预设条件的设置方式不加以限定。
可选地，终端设备通过放大器将第二电信号的幅度放大至预设幅度值；当放大后的第二电信号的参数大于预设门限阈值时触发第二指定事件。
终端设备判断放大后的第二电信号是否大于预设门限阈值，若放大后的第二电信号的参数大于预设门限阈值则表示满足第二预设条件，触发第二指定事件；否则，结束进程。
可选地，放大后的第二电信号的参数用于指示放大后的第二电信号的大小，放大后的第二电信号的参数包括放大后的第二电信号的峰值或者有效值或者平均值。本公开实施例对此不加以限定。
第二指定事件为预先设置的目标应用程序中的人机交互事件。可选地，目标应用程序为阅读应用程序，第二指定事件为对阅读应用程序中显示的目标文档进行翻页的事件。本实施例对目标应用程序和第二指定事件的类型不加以限定。
可选地，当放大后的第二电信号的参数大于预设门限阈值时，终端设备开启模数转换模块；通过模数转换模块对吹气的幅度做判断，配合第二指定事件的执行强度。即通过模数转换模块将放大后的 第二电信号转化为数值参数；根据数值参数执行第二指定事件，数值参数用于指示第二电信号的参数大小，第二电信号的参数大小与第二指定事件的执行强度呈正相关关系。
可选地，终端设备根据放大后的第二电信号的参数大小，通过模数转换模块将放大后的第二电信号转化为数值参数，数值参数用于指示第二电信号的参数大小。
示意性的，预先设置多个信号范围和多个信号范围各自对应的数值参数，多个信号范围之间不存在交集。当放大后的第二电信号的参数大小在一个信号范围内，则将该放大后的第二电信号转化为该信号范围对应的数值参数。
比如，预先设置四个信号范围和这四个信号范围各自对应的数值参数，比如，四个数值参数分别为“00”、“01”、“10”和“11”，其中数值“00”对应第一信号范围，数值“01”对应第二信号范围，数值“10”对应第三信号范围，数值“11”对应第四信号范围，第一信号范围小于第二信号范围，第二信号范围小于第三信号范围，第三信号范围小于第四信号范围，且这四个信号范围不存在交集。
可选地，终端设备根据预设对应关系，获取与数值参数对应的第二指定事件的执行强度。预设对应关系为数值参数与第二指定事件的执行强度之间的对应关系。按照数值参数对应的第二指定事件的执行强度，执行第二指定事件。
其中，数值参数用于指示第二电信号的参数大小，第二电信号的参数大小与第二指定事件的执行强度呈正相关关系。即第二电信号的参数大小越大，第二指定事件的执行强度越大。
示意性的，目标应用程序为阅读应用程序，第二指定事件为对阅读应用程序中显示的目标文档进行翻页的事件。第二电信号的参数大小越大，翻页页数越大。比如，数值参数“00”对应的翻页页数为“1页”，数值参数“01”对应的翻页页数为“2页”，数值参数“10”对应的翻页页数为“3页”，数值参数“11”对应的翻页页数为“4页”。
示意性的，目标应用程序为视频应用程序，第二指定事件为对视频应用程序中播放的目标视频进行快进的事件。第二电信号的参数大小越大，快进跨度越大。比如，数值参数“00”对应的快进跨度为“1秒”，数值参数“01”对应的快进跨度为“2秒”，数值参数“10”对应的快进跨度为“3秒”，数值参数“11”对应的快进跨度为“4秒”。本公开实施例对此不加以限定。
在一个示意性的例子中，如图4所示，终端设备为手机，交互对象为用户，手机中包括扬声器41、 放大器42和模数转换模块43，第一指定事件为亮屏事件，第二指定事件为对阅读应用程序中显示的目标文档进行翻页的事件。在手机处于熄屏休眠状态的情况下麦克风42处于关闭状态，用户对着手机的扬声器41吹气，扬声器41接收用户的吹气并产生电信号，手机通过放大器对该电信号进行放大处理后进行门限判决，若放大后的电信号的参数大于预设门限阈值时触发亮屏事件，将手机的屏幕状态从熄屏状态切换为亮屏状态。在手机处于亮屏唤醒状态且阅读应用程序处于前台运行的情况下，用户对着手机的扬声器41吹气，同样的，扬声器41接收用户的吹气并产生电信号，通过放大器对该电信号进行放大处理后进行门限判决，若放大后的电信号的参数大于预设门限阈值时触发第二指定事件，并开启模数转换模块43，通过模数转换模块将放大后的电信号转化为数值参数“00”，获取与数值参数“00”对应的翻页页数为“1页”，则手机对阅读应用程序中显示的目标文档翻一页。
综上所述，本公开实施例还通过当放大后的第二电信号的参数大于预设门限阈值时，终端设备开启模数转换模块；通过模数转换模块将放大后的第二电信号转化为数值参数，数值参数用于指示第二电信号的参数大小；根据数值参数执行第二指定事件，第二电信号的参数大小与第二指定事件的执行强度呈正相关关系；使得通过模数转换模块对吹气的幅度做判断，从而确定第二指定事件的执行强度，比如阅读文档时的翻页页数，扩展了非接触式人机交互的应用场景。
