随着通信技术的发展，用户所佩戴的穿戴设备的种类越来越多样，穿戴设备可为智能手环、无线耳机、眼镜等。
现有技术所提供的穿戴设备支持采用蓝牙、无线保真(wireless fidelity，WIFI)通信，所以穿戴设备可通过蓝牙、WIFI等进行信息交互。

本发明实施例提供了一种信息的交互方法，该方法用于有效的提高穿戴设备的待机时长，且能够有效的提高所交互的信息的信号质量，为更好的理解本申请所提供的信息的交互方法，以下首先对本申请所示的信息的交互方法所应用的人体交互系统的具体结构进行示例性说明：
如图1所示，所述人体交互系统包括目标用户的人体101、终端102以及目标用户所佩戴的多个穿戴设备，本实施例对穿戴设备的具体设备类型不做限定，只要该穿戴设备能够实现不同的穿戴设备之间的信息的交互，和/或实现该穿戴设备和终端102之间的信息交互即可；

基于图1所示的人体交互系统，以下结合图2所示对本实施例所提供的信息的交互方法的具体执行流程进行示例性说明：
步骤201、第一穿戴设备获取待交互信息。
本实施例所示的第一穿戴设备和第二穿戴设备为目标用户所佩戴的多个穿戴设备中的任意两个，且所述第一穿戴设备用于将所获取到的待交互信息向所述第二穿戴设备发送。其中，所述第一穿戴设备可为图1所示的智能手环、眼镜、无线耳机等，具体在本实施例中不做限定。
本实施例对所述待交互信息的具体信息类型不做限定，在所述第一穿戴设备的设备类型有所不同的情况下，所述待交互信息的信息类型也会有所不同；例如，在所述第一穿戴设备为无线耳机中的主耳机，而第二穿戴设备为无线耳机中的从耳机的情况下，所述待交 互信息为音频信息；又如，若所述第一穿戴设备为智能手坏，所述第二穿戴设备为无线耳机，则所述待交互信息也可为音频信息，又如，若所述第一穿戴设备为无线耳机，所述第二穿戴设备为智能手环，则所述待交互信息可为传感器数据，所述传感器数据包括但不限于第一穿戴设备所集成的传感器所采集的到人体的心率、血氧等健康信息，又如，所述待交互信息还可为设备信息，该设备信息包括但不限于终端的剩余电量信息等。
本实施例对所述第一穿戴设备获取所述待交互信息的具体方式不做限定，只要所述第一穿戴设备能够将所获取到待交互信息向所述第二穿戴设备发送即可，以下对所述第一穿戴设备获取待交互信息的几种可选的方式进行示例性说明：
方式1
所述第一穿戴设备通过短距离通信网络，从所述终端获取所述待交互信息，本实施例对所述短距离通信网络的具体通信类型不做限定，例如，所述短距离通信网络可为如下所示的一种或多种：
直接式红外线(direct-beamir)、散射式红外线(diffuseir)、全向性红外线(ominidirectionalir)、蓝牙、WIFI、紫蜂协议(ZigBee)、或近场通信(NFC)等。
例如，若所述第一穿戴设备为无线耳机中的主耳机，而所述第二穿戴设备为无线耳机中的从耳机，则主耳机可通过短距离通信网络从终端获取音频信息(即待交互信息)，所述主耳机即可通过如下步骤所示将该音频信息向从耳机发送。
方式2
所述第一穿戴设备基于虚拟用户身份识别卡，通过射频通信网络获取所述待交互信息，具体的，本方式所示的第一穿戴设备内集成有虚拟用户身份识别卡(subscriber identification module，SIM)，本实施例所示的虚拟SIM包括但不限于嵌入式用户识别卡(embedded subscriber identification module，ESIM)、软件SIM(soft SIM)或虚拟SIM(virtual SIM，vSIM)。
例如，所述第一穿戴设备可为智能手环，第二穿戴设备为无线耳机，所述智能手环用于基于虚拟SIM以实现通过射频通信网络向基站获取通话数据(即待交互信息)，所述智能手环即可通过如下步骤所示将该通话数据向无线耳机发送。
方式3
所述第一穿戴设备通过已集成的传感器，获取所述待交互信息，本实施例对所述第一穿戴设备所集成的传感器的具体类型不做限定，例如，所述传感器可为如下所示的一种或多种传感器：
近光传感器、环境光传感器、霍尔传感器、电容传感器、加速度传感器或心率检测传感器等。
例如，所述第一穿戴设备可为无线耳机，所述第二穿戴设备可为智能手环，则所述无线耳机基于传感器可采集到传感器数据(即待交互信息)，所述传感器数据可为目标用户的心率信息，则所述无线耳机可通过如下步骤所示，将目标用户的心率信息向智能手环发送。
步骤202、所述第一穿戴设备确定人体通信通道。
以下首先对人体通信通道进行说明：
本实施例所示的第一穿戴设备基于无线体域网(wireless body area network，wban)确定所述人体通信通道,该无线体域网是指建立在目标用户所佩戴的多个穿戴设备之间的信息网络，在网络分级中比局域网更低一级，本实施例所示的第一穿戴设备可基于无线体域网的人体通信技术，确定所述人体通信通道，其中，人体通信技术是指，利用人体作为信息通道传输信息的方式，其可行性是建立在人体具有的导电能力基础之上的，具体的，由于人体组织中有60％以上是由含有导电物质的水分组成，因此，人体是个导体。人体通信技术是利用人的身体作为通信信号传输媒介的一种通信方式。
在本实施例中，所述第一穿戴设备基于人体通信技术的电容耦合方式，与目标用户进行电容耦合，使能目标用户的人体产生电场以确定人体通信通道，具体的，电容耦合方式是指，利用第一穿戴设备的振荡让人体产生电场，并由第二穿戴设备检测电场的变化，从而实现通信。更具体的，第一穿戴设备可包括两个电极，其中一个电极与人体进行电容耦合，另一个电极与地进行电容耦合来确定人体通信通道。
以下对所述人体通信通道所传输的待交互信息的频率进行示例性说明：
所述人体通信信道的频率为目标区间内的任一数值，所述目标区间的最小值为6千赫兹(6kHz)，所述目标区间的最大值为100兆赫(MHz)。
具体的，大于10kHz的高频信号可以通过高阻抗的细胞膜，但是由于人体内存在许多不同频率额50kHz以下的人电信号，为了保持人体通信的安全性和可靠性，人体通信的信号工作频率应该保持在50kHz以上。由于100kHz-100MHz的射频信号在人体中的传输效率高于在空气中的传输效率，所以通讯频率需要限制在100kHz-100MHz之间，所述人体通信通道的通信速度小于或等于10兆比特每秒。
又因为子带编码(sub-band coding，SBC)、高级音频编码(advanced audio coding，AAC)等编解码信号的带宽在100-300千比特每秒(kbps)之间，高清的96kHz/24bit音频信号，如无损音频更是需要2兆比特每秒(Mbps)以上的带宽，再加上其它传感器信号，以及数据采集信号等，所以人体通信信道可以100kHz-100MHz之间之内选择。需明确的是，本实施例对所述人体通信通道的频率的说明不做限定，只要所述第一穿戴设备能够通过该人体通信通道进行待交互信息的发送即可。
步骤203、所述第一穿戴设备通过所述人体通信信道，向所述第二穿戴设备发送所述待交互信息。
本实施例中，在所述第一穿戴设备获取到所述待交互信息，且已确定所述人体通信通道的情况下，所述第一穿戴设备即可通过所述人体通信通道，向所述第二穿戴设备发送所述待交互信息。
采用本实施例所示的方法，因所述第一穿戴设备通过人体通信通道向第二穿戴设备发送所述待交互信息，使得发送过程中的频率和功耗都比较低，所以对人体不会产生伤害，而且利用人体是一个电容来做电容耦合，所受到环境的干扰是非常有限，即便第一穿戴设备所处于的通信环境中的蓝牙信号和WIFI信号等，这些信号都不会对人体通信信道造成干扰，从而使得第一穿戴设备通过人体通信通道将待交互信息发送给第二穿戴设备，能够 有效的保障信息传输的稳定和质量，又因人体通信通道进行待交互信息的传输，所耗费的功耗比较低，从而有效的提高了穿戴设备的待机时长。
以下结合图3所示，对本申请所提供的信息的交互方法的另一种执行流程进行示例性说明：
步骤301、第一穿戴设备获取待交互信息。
本实施例所示的步骤301的具体执行过程，请详见图2所示的步骤201所示，具体执行过程，不做赘述。
步骤302、第一穿戴设备判断所述第一穿戴设备与所述目标用户之间的距离是否大于或等于第一预设距离，若是，则执行步骤303，若否，则执行步骤304。
本实施例中，所述第一穿戴设备可预先确定第一预设距离，其中，所述第一预设距离是指，在所述第一穿戴设备和目标用户之间的距离大于或等于该第一预设距离时，所述第一穿戴设备无法基于人体确定所述人体通信通道，具体的，若目标用户没有正常穿戴该第一穿戴设备，则该第一穿戴设备无法通过人体通信通道向第二穿戴设备发送待交互信息，具体例如，若所述第一穿戴设备为主耳机，则在目标用户摘下主耳机的情况下，与目标用户已脱离的主耳机无法通过人体通信通道向副耳机发送待交互的音频信息。
可选的，本实施例所示的第一穿戴设备可基于已集成的距离传感器获取所述第一穿戴设备与所述目标用户之间的距离，本实施例对所述第一穿戴设备获取所述第一穿戴设备与所述目标用户之间的距离的具体过程不做限定。
本实施例对所述第一预设距离的大小不做限定，只要在第一穿戴设备与目标用户之间的距离大于或等于该第一预设距离的情况下，该第一穿戴设备无法通过人体通信通道向第二穿戴设备发送待交互信息，而在第一穿戴设备与目标用户之间的距离小于该第一预设距离的情况下，该第一穿戴设备能够通过人体通信通道向第二穿戴设备发送待交互信息即可。
步骤303、所述第一穿戴设备生成提示信息。
具体的，在所述第一穿戴设备确定出第一穿戴设备与目标用户之间的距离大于或等于该第一预设距离的情况下，则第一穿戴设备确定无法通过人体通信通道进行待交互信息的发送，则所述第一穿戴设备可生成提示信息，本实施例对所述提示信息的具体信息类型不做限定，只要所述提示信息用于指示无法进行人体通信通道的通信即可，例如，所述提示信息可为音频信息或字符信息等。在目标用户接收到提示信息的情况下，所述目标用户即可重新对第一穿戴设备进行调整，以使目标用户能够成功佩戴所述第一穿戴设备。
可选的，所述第一穿戴设备可周期性的执行步骤302，以使在目标用户调整了第一穿戴设备后，通过执行步骤302，以使第一穿戴设备确定出所述第一穿戴设备与所述目标用户之间的距离已小于所述第一预设距离的情况，进而触发执行步骤304。
步骤304、所述第一穿戴设备确定人体通信通道。
步骤305、所述第一穿戴设备通过所述人体通信信道，向所述第二穿戴设备发送所述待交互信息。
本实施例所示的步骤304至步骤305之间的执行过程，请详见图2所示的步骤202至步骤203所示，具体执行过程请详见图2所示，具体不做赘述。
采用本实施例所示的方法，所述第一穿戴设备可周期性的检测所述第一穿戴设备和目标用户之间的距离是否小于第一预设值，只有在第一穿戴设备与目标用户之间的距离小于第一预设值的情况下，才会通过人体通信通道进行待交互信息的发送，提高了通过人体通信通道进行待交互信息发送的成功率，避免了因目标用户没有成功佩戴第一穿戴设备的情况下，待交互信息没有成功发送至第二穿戴设备的情况的出现。
以下结合图4所示，对本申请所提供的信息的交互方法的另一种执行流程进行示例性说明：
步骤401、第一穿戴设备获取待交互信息。
本实施例所示的步骤401的具体执行过程，请详见图2所示的步骤201所示，具体执行过程在本实施例中不做赘述。
步骤402、所述第一穿戴设备检测所述第一穿戴设备和所述第二穿戴设备之间的目标距离；
具体的，在所述第一穿戴设备确定出需要向第二穿戴设备发送待交互信息的情况下，所述第一穿戴设备可首先检测所述第一穿戴设备和所述第二穿戴设备之间的目标距离。
可选的，所述第一穿戴设备可基于已集成的距离传感器获取所述第一穿戴设备和所述第二穿戴设备之间的目标距离，具体过程在本实施例中不做赘述。
步骤403、所述第一穿戴设备判断所述目标距离是否小于或等于第二预设距离，若否，则执行步骤404，若是，则执行步骤405。
本实施例对所述第二预设距离的大小不做限定，只要在第一穿戴设备与第二穿戴设备之间的目标距离大于该第二预设距离的情况下，该第一穿戴设备无法通过人体通信通道向第二穿戴设备发送待交互信息，而在第一穿戴设备与第二穿戴设备之间的目标距离小于或等于该第二预设距离的情况下，该第一穿戴设备能够通过人体通信通道向第二穿戴设备发送待交互信息。
步骤404、所述第一穿戴设备通过短距离通信网络向所述第二穿戴设备发送所述待交互信息。
在所述第一穿戴设备和所述第二穿戴设备之间的目标距离大于所述第二预设距离时，所述第一穿戴设备即可确定出，所述第一穿戴设备无法通过人体通信通道向第二穿戴设备发送所述待交互信息，则所述第一穿戴设备可通过短距离通信网络向所述第二穿戴设备发送所述待交互信息，对所述短距离通信的具体说明，请详见上述实施例所示，具体在本实施例中不做赘述。
步骤405、所述第一穿戴设备确定人体通信通道。
在所述第一穿戴设备和所述第二穿戴设备之间的目标距离小于或等于所述第二预设距离时，所述第一穿戴设备即可确定出，所述第一穿戴设备可通过人体通信通道向第二穿戴设备发送所述待交互信息，即可执行步骤405。
步骤406、所述第一穿戴设备通过所述人体通信信道，向所述第二穿戴设备发送所述待交互信息。
本实施例所示的步骤405至步骤406之间的执行过程，请详见图2所示的步骤202至步骤203所示，具体执行过程请详见图2所示，具体不做赘述。
步骤407、若所述第一穿戴设备通过所述人体通信信道未接收到响应消息，则所述第一穿戴设备通过短距离通信网络向所述第二穿戴设备发送所述待交互信息。
本实施例中，为提高第一穿戴设备向第二穿戴设备发送所述待交互信息的成功率，则所述第一穿戴设备可周期性的检测是否接收到第二穿戴设备发送的响应消息，其中，所述响应消息用于指示所述第二穿戴设备已成功接收到所述待交互信息。
在所述第一穿戴设备确定出通过所述人体通信通道未接收到第二穿戴设备所发送的响应消息，则说明所述第二穿戴设备未成功接收到第一穿戴设备所发送的所述待交互信息，则说明经由所述人体通信通道所传输的待交互信息出现了丢包，则所述第一穿戴设备可通过短距离通信网络向第二穿戴设备发送所述待交互信息，对所述短距离通信网络的具体说明，请详见上述实施例所示，具体在本实施例中不做赘述。
采用本实施例所示的方法，所述第一穿戴设备检测所述第一穿戴设备和第二穿戴设备之间的距离是否小于或等于第二预设值，只有在第一穿戴设备与第二穿戴设备之间的距离小于或等于第二预设值的情况下，才会通过人体通信通道进行待交互信息的发送，提高了通过人体通信通道进行待交互信息发送的成功率，而且在检测到第一穿戴设备与第二穿戴设备之间的距离大于第二预设值的情况下，第一穿戴设备可通过短距离通信网络发送所述待交互信息，避免了待交互信息没有成功发送至第二穿戴设备的情况的出现。
为更好的理解本申请所提供的信息的交互方法，以下结合具体应用场景进行示例性说明；
场景1，本场景以第一穿戴设备为无线耳机中的主耳机，第二穿戴设备为无线耳机中副耳机，且以待交互信息为音频信息为例；具体的，本场景中的无线耳机为TWS耳机；
TWS耳机产品形态和功能相对以往的蓝牙耳机实现了大幅创新，既摆脱了传统轻便型蓝牙耳机只有单耳，无法享受立体声音乐的缺陷，又摆脱了传统颈挂式或者头戴式耳机，有一根连接线，导致运动场景不方便，以及收纳的困难。TWS耳机已经掀起了一股热潮，迎来快速增长期，TWS耳机已经带动了无线耳机的消费热潮，是对传统蓝牙耳机的取代，市场规模可观，据测算，到2020年市场规模有望超过150亿美金。从以上发展可以看到，未来伴随着手机全屏化、无孔化的发展趋势，TWS耳机有望成为标配。
首先，如图5所示，主TWS耳机501可先通过蓝牙或WIFI等短距离通信网络与终端502建立连接，以使主TWS耳机能够从终端502获取音频信息，其中，该音频信息包括与主TWS耳机501对应的音频信息和与副TWS耳机503对应的音频信息；
主TWS耳机501将接收到的音频信息在本地编解码后，获取到主TWS耳机501对应的音频信息和与副TWS耳机503对应的音频信息；
其次，主TWS耳机501通过人体通信通道向副TWS耳机503发送与副TWS耳机503对 应的音频信息。参见图6所示，所述主TWS耳机501包括用于与人体601进行电容耦合的电极602，所述主TWS耳机501即可通过已创建的人体通信通道将副TWS耳机503对应的音频信息，发送给副TWS耳机503。
这么做的优势在于，主TWS耳机501通过人体通信通道向副TWS耳机503发送音频信息的功耗低，传输效率高，不会造成播放延时大，从而使得在播放电影或者打游戏的场景下，能够有效的保障主TWS耳机501与副TWS耳机503之间的音频信息的同步。而且通过人体通信通道进行音频信息的传输，可有效的保障副TWS耳机503的通讯信号的稳定，不会出现音乐卡顿和通话断续现象。
可选的，若出现主TWS耳机501的音频信息的丢包现象，则主TWS耳机501会直接发送用于指示丢包的消息给终端502，以通知终端502该主TWS耳机501出现丢包，终端502会重传音频信息给主TWS耳机501。若出现副TWS耳机503出现丢包，副TWS耳机503需要先发送用于指示丢包的消息给主TWS耳机501，主TWS耳机501再发送用于指示丢包的消息给终端502，终端502则重传音频信息给主TWS耳机501，主TWS耳机501再通过人体通信通道将音频信息重传给副TWS耳机503。
场景2，本应用场景中，如图7所示，第一穿戴设备701可为智能手环，第二穿戴设备为主TWS耳机702，第三穿戴设备为副TWS耳机703；
本场景中，第一穿戴设备701可通过蓝牙、WIFI等短距离通信网络和终端704建立连接，终端704即可将音频信息发送给主TWS耳机702和副TWS耳机703，可选的，本场景下的音频信息还可为第一穿戴设备通过已设置的虚拟SIM从基站处获取到的用于进行通话的音频信息，本场景下的具体发送的方式有如下三种：
方式1
首先，第一穿戴设备701可将从终端704所获取到的音频信息，通过人体通信信道将该音频信息发送给主TWS耳机702，其中，该音频信息包括与主TWS耳机702对应的音频信息和与副TWS耳机703对应的音频信息；
主TWS耳机702将接收到的音频信息在本地编解码后，获取到主TWS耳机702对应的音频信息和与副TWS耳机703对应的音频信息；
其次，主TWS耳机702通过人体通信通道向副TWS耳机703发送与副TWS耳机703对应的音频信息。
可选的，若出现主TWS耳机702的音频信息的丢包现象，则主TWS耳机702会直接发送用于指示丢包的消息给终端704，以通知终端704该主TWS耳机702出现丢包，终端704会重传音频信息给主TWS耳机702。若出现副TWS耳机703出现丢包，副TWS耳机703需要先发送用于指示丢包的消息给主TWS耳机702，主TWS耳机702再发送用于指示丢包的消息给终端704，终端704则重传音频信息给主TWS耳机702，主TWS耳机702再通过人体通信通道将音频信息重传给副TWS耳机703。
方式2
第一穿戴设备701可将从终端704所获取到的音频信息，通过人体通信信道同步发送给主TWS耳机702和副TWS耳机703，从而使得主TWS耳机702和副TWS耳机703能够实 现双耳同时接收音频信息，并同时将接收到的音频信息在本地解码播放。
可选的，若出现音频信息丢包，例如，若副TWS耳机703丢包，则副TWS耳机703丢包可通过人体通信通道将用于指示丢包的消息发送给主TWS耳机702，由主TWS耳机702将用于指示丢包的消息通过人体通信通道发送给第一穿戴设备701；若主TWS耳机702出现丢包，则由主TWS耳机702将用于指示丢包的消息通过人体通信通道发送给第一穿戴设备701。
采用上述场景，主TWS耳机和副TWS耳机可佩带于同一目标用户的人体上，也可佩带于不同目标用户的人体上，例如，主TWS耳机可佩带于第一目标用户的人体上，而副TWS耳机可佩带于第二目标用户的人体上，本场景下的人体通信通道包括第一目标用户的人体和第二目标用户的人体，具体的，只要所述第一目标用户的人体和第二目标用户的人体之间的距离足够近，则第一目标用户的人体和第二目标用户的人体即可连接以形成所述人体通信通道，则使得主TWS耳机可将音频信息通过包括有第一目标用户的人体和第二目标用户的人体，发送给副TWS耳机，从而使得第一目标用户通过主TWS耳机，第二目标用户通过副TWS耳机可接收到相同的音频信息。
场景3
