目前终端设备之间数据传输的方式，主要有两大途径：一种是近距离传输：例如，通过通用串行总线(Universal Serial Bus，USB)、WIFI、蓝牙、近场通信(Near Field Communication，简称NFC)等作为直连传输通道，另一种是联网传输：借助局域网传输软件、互联网社交软件等完成终端设备间的数据传输。各种传输方式大都需要用户进行繁琐的操作。
发明内容
本申请的目的在于提供一种简洁易用的内容传输方案。
本申请的第一方面提供了一种内容传输方法，该方法可以包括：第一设备确定与第二设备之间的距离小于距离阈值；第一设备提示用户第一设备与第二设备之间可进行内容传输；第一设备识别用户对第一设备的手势操作，并根据识别出的手势操作确定传输内容和传输内容在第一设备与第二设备之间的传输方向；第一设备根据确定的传输方向，从第二设备接收传输内容或向第二设备发送传输内容。

具体实施方式
下面结合具体实施例和附图对本申请做进一步说明。可以理解的是，此处描述的具体实施例仅仅是为了解释本申请，而非对本申请的限定。此外，为了便于描述，附图中仅示出了与本申请相关的部分而非全部的结构或过程。应注意的是，在本说明书中，相似的标号和字母在下面的附图中表示类似项。
本申请的说明性实施例包括但不限于内容传输方法、设备及介质等。
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请的实施方式作进一步地详细描述。在附图中，参考数字后面的字母，例如“100a”表示对具有该特定参考数字的元素的引用。文本中没有后续字母的参考数字，例如“100”，表示对带有该参考数字的元件的实施方式的一般引用。
目前，在已有的传输技术中，在终端设备之间的数据传输方式大都需要用户进行多个步骤的繁琐操作：例如，如果第一终端设备要分享内容给第二终端设备，通常需要用户在第一终端设备上进行多步操作，例如：选定传输内容，查找、发现和选择目标设备，点击分享，再完成传输等。分享过程较为繁琐。有一些将多个步骤简化为一步分享的方式(例如采用通过NFC触碰、声音、超声波、快捷键等方式一步分享数据)，但是这些方式非常容易导致数据分享方向误判，例如，用户原本希望由第一终端设备传输到第二终端设备，但是由于误触、误操作，可能会导致第二终端设备的数据被传输到了第一终端设备，影响用户体验。
本申请的实施例旨在提供一种基于距离和手势分享内容的方案，简化分享操作的同时，避免数据传输方向的误判。本申请的实施例提供的内容分享方法适用于终端设备之间的内容分享，例如两个终端设备之间的内容同步、传输等。
图1示出了一种终端设备间进行近距离内容分享的场景示例。
如图1所示，根据本申请的一些实施例，提供一种数据分享系统10，数据分享系统10中可以包括两个终端设备100，例如：手机100a和电脑100b。用户可以手持手机100a向电脑100b靠近，以实现近距离的内容分享。
在如图1所示的数据分享系统10中，手机100a中可以包括磁传感器，而电脑100b中会包括 大量的磁器件。在手机100a周围没有磁性器件或设备的平稳状态下，手机100a通过磁传感器感测到的磁感应信号的强度也是平稳的，而当手机100a与电脑100b靠近时，手机100a的磁传感器会受到电脑100b的磁器件的影响，导致手机100a端的磁感应信号强度出现剧烈波动。因此，可以以手机100a监测到磁感应信号强度的变化超过一定的强度变化阈值作为触发条件，随后两终端设备100可以通过蓝牙广播或超声波等验证两终端设备100之间的距离是否足够近，在两终端设备间的距离处于预设范围的情况下，触发传输，随后再通过用户手势来判断数据在手机100a与电脑100b之间的传输方向，从而实现两终端设备间的内容分享。本申请的实施例旨在基于终端设备中的磁传感器、蓝牙或超声波能力等来精准地识别设备间的距离，并配合用户手势，实现两终端设备间的便捷而准确的内容分享。
根据本申请的一些实施例，终端设备100不仅限于图1中所示的手机100a和电脑100b，其可以是包括内存和硬件处理器的各种计算设备。例如，终端设备100的示例可以包括：手机、相机、平板计算机、台式计算机、膝上型计算机、车载终端、智能语音终端、便携式游戏机、便携式音乐播放器、读取器设备、可穿戴设备、智能家居设备、增强现实(augmented reality，AR)设备、虚拟现实(virtual reality，VR)设备等各种电子设备。终端设备100的示例性实施例包括但不限于搭载IOS、Android、Microsoft或者其它操作系统的各种电子设备。
在一些实施方式中，终端设备100可以是由用户穿戴的可穿戴设备。例如，终端设备100可以是手表、手环、首饰、眼镜等，或者作为他们的一部分。在各种实施方式中，用户可以在终端设备100的显示器上查看消息或者可以经由设备的扬声器或其他输出设备来访问消息等。在另一示例中，用户可以经由耦合到终端设备100或作为终端设备100的一部分的耳机、终端设备100的扬声器、终端设备100的触觉反馈元件等来访问消息。
终端设备100可以通过网络与其他设备实现交互，在各种实施方式中，前述网络可以是有线网络或无线网络，并且可以具有许多不同的配置。前述网络可以包括局域网(LAN)、广域网(WAN)(例如，因特网)等各种互连数据路径。网络还可以耦合到或包括电信网络的部分，用于以各种不同的通信协议发送数据。在一些实施方式中，网络也可以包括用于发送和接收数据的蓝牙通信网络、Wi-Fi或蜂窝通信网络等。
终端设备100的具体结构示例将在后文结合图5至图8进行具体说明。
下面结合图2和图4，以图1中的手机100a和电脑100b为例，详细描述终端设备100之间分享内容的过程。
根据本申请的实施例，图2示出了手机100a与电脑100b之间分享内容的交互过程。
首先，S1：手机100a与电脑100b靠近，通过蓝牙识别对方身份，并进行蓝牙配对建立长连接，例如，建立低功耗蓝牙(Bluetooth Low Energy，BLE)长连接。在一些实施方式中，手机与电脑可以通过如图5中所示的无线通信模块160或其他类似的模块来通信地耦合，以建立BLE长连接。
S2：建立连接后，两终端设备首先进行数据传输意图的触发，手机100a通过内部的磁传感器实时监测手机100a的磁感应信号强度的变化。
在本发明的实施例中，利用了手机100a中的磁传感器可以检测当前环境中的磁场强度的特性，当有磁性干扰源靠近的时候，磁传感器可以识别到当前磁场强度数据发生了不正常变化。而电脑等设备本身作为一个复杂的磁场，在电脑100b中会存在大量的磁性器件，当电脑100b靠近手机100a的时候，是一定可以成为一个磁性干扰源的，本申请通过手机100a中的磁传感器检测磁性 干扰源来识别是否有设备靠近，在无磁性干扰源靠近手机100a时，手机100a检测到的磁感应信号的强度是比较平稳的，而当电脑100b靠近手机100a时，手机100a检测到的磁感应信号的强度会出现剧烈的变化或波动，通过监测磁感应信号强度的变化是否超过预设的强度变化阈值可以确定变化或波动的剧烈程度，从而识别是否有磁干扰源的靠近。
S3：当电脑100b靠近手机100a时，手机100a端的磁传感器会监测到磁感应信号强度的剧烈变化，该磁感应信号强度的剧烈变化可以作为手机100a与电脑100b之间意图分享内容的触发事件。
S4：在手机100a监测到磁感应信号强度的变化超过预设的强度变化阈值(即，S3中判断为是)的情况下，即说明手机100a监测到的磁感应信号的强度发生了剧烈变化，这意味着手机100a附近有磁干扰源出现，但是，手机100a监测到磁干扰并不意味着一定是电脑100b等其他终端设备在靠近，该磁干扰源可能是电脑100b，也可能是其他设备或者器件，例如磁铁等。为了验证靠近手机100a的到底是与手机100a长连接的电脑100b，还是其他磁干扰源，手机100a可以开启蓝牙广播信号，以通过蓝牙测量手机100a与电脑100b之间的距离。
S5-S6：手机100a与电脑100b之前之间已经建立蓝牙长连接，电脑100b可以接收手机100a发来的蓝牙信号，根据接收到的蓝牙信号的强度，确定自己与手机100a之间的距离，并将确定的距离与预设阈值进行比较，判断自己与手机100a之间的距离是否小于预设的距离阈值。
电脑100b可以根据蓝牙接收信号强度指示(Received Signal Strength Indicator，RSSI)，来计算自己与手机100a之间的距离D，如下面的公式(1)所示：
D＝10^((abs(RSSI)-A)/(10*n))      (1)
其中：
D为发射端(即手机100a)与接收端(即电脑100b)之间的距离；
RSSI为接收信号强度(负值)；
A为发射端(即手机100a)和接收端(即电脑100b)相隔1米时的信号强度；
n为环境衰减因子。
S7：为了提高距离测量的准确性，可以在手机100a和电脑100b两端都开启距离校验，即电脑100b接收到手机100a的蓝牙信号后，也开启蓝牙广播。
S8-S9：在手机100a端，手机100a也可以根据接收到的来自电脑100b的蓝牙信号的强度，确定自己与电脑100b之间的距离，并判断自己与电脑100b之间的距离是否小于预设的距离阈值。
这样，手机100a和电脑100b这两个终端设备通过双重校验，可以进一步提高距离监测的准确性。在手机100a端和电脑100b端均判定手机100a与电脑100b之间的距离小于预设的距离阈值的情况下，证明手机100a端的磁感应信号强度的剧烈变化事件并不是其他磁干扰源带来的误触发，而确实是手机100a与电脑100b靠近带来的磁干扰事件。
本发明的实施例中提供的这种在磁感应触发内容分享事件后，通过判断终端设备之间的距离来进一步校验的方式可以提高后续内容传输的安全性。否则，如果没有距离判断的操作，在手机100a与电脑100b距离很远的情况下，通过在手机100a附近提供诸如磁铁之类的各种磁器件都有可能会导致手机100a的磁感应信号强度的剧烈变化，从而触发内容的传输，这会带来数据泄露的风险。
根据本申请的一些实施例，也可以不通过手机100a和电脑100b这两个终端设备的双重校验，而只通过单端测距来校验磁感应触发事件即可。此外，在手机100a或电脑100b上安装有符合蓝 牙5.1标准的蓝牙模块的情况下，单端测距即可实现较高的准确度，在这种情况下，无需再进行两端的双重校验。
此外，根据本申请的一些实施例，手机100a与电脑100b间距离的测量也可以采用其他方案进行，或者采用多种测距方案的结合来进行，其中，其他测距方案可以包括但不限于，毫米波测距、超声波测距等。
在判定手机100a与电脑100b之间的距离小于预设的距离阈值的情况下，可以确定手机100a与电脑100b之间满足内容分享条件。
根据本申请的一些实施例，通过S4至S9的距离校验操作确定手机100a与电脑100b之间满足内容分享条件后，手机100a可以输出特定的图案、音效、振动或动态界面效果等，以提醒用户可以开始手势操作以分享内容。
S10：手机100a识别用户手势，根据用户手势确定要传输的内容和传输的方向。
根据本申请的一些实施例，用户的手势可以是用户手持手机100a的移动，在这种情况下，可以通过监测手机100a的移动方式(如左移、右移等等)来判断用户的手势，并且每个手势可以被映射到要启动的特定操作。
手机100a的移动方式(如左移、右移等等)可以通过手机100a中的重力传感器来检测手机100a的加速度的变化来获取。
重力传感器又称重力感应器，它能够感知手机100a在各个方向上的加速度的大小，进而通过加速度值来判断手机100a的运动，比如左右晃动、上升、下降等。当手机100a静止时，重力传感器可检测出重力的大小及方向。手机100a中的重力传感器通常为三轴结构，重力传感器通过三轴可以感知任意方向上的加速度，判断手机100a的空间运动。
重力传感器在进行三轴的加速度运算时，重力感应坐标通常是相对于手机100a而言，而不是空间坐标。例如，参见图3，将手机正面朝上以正对方向平放在桌面上，重力传感器能够感知手机100a在图示X、Y、Z三轴的加速度数值。其中，X轴为左右方向，Y轴为前后方向，Z轴为上下方向，重力传感器测得的三轴加速度的数值包含地心引力的影响，单位是m/s^2。在静止状态下，X轴加速度默认为0，Y轴默认0，Z轴默认9.81。
在X轴方向上，如果手机100a突然向左移动，则X轴加速度值为正值，而如果手机突然向右移动，X轴加速度值则为负值。
在Y轴方向上，如果手机100a突然向前移动，则Y轴加速度值为正值，而如果手机突然向后移动，Y轴加速度值则为负值。
在Z轴方向上，如果手机100a突然向上移动，则Z轴加速度值为大于9.81，而如果手机突然向下移动，Z轴加速度值则为小于9.81。
因此，重力传感器启动后，在用户没有手势动作时，重力传感器测得的加速度信号会相对平稳；而当用户有手势动作时，加速度信号会变化剧烈，通过加速度信号的差分值可显示出信号变化的剧烈程度；当手势结束后，加速度信号会恢复平稳。因此可以用加速度差分值来实时判断手机100a移动的起点和终点，并判断手机100a移动的具体方向。具体过程如下：
首先，对于重力传感器测得的加速度数据进行采样，对于第k个采样点，三轴的加速度差分值可以通过式(2)计算：
Δa k＝(ax k-ax k-1)+(ay k-ay k-1)+(az k-az k-1)     (2)
其中，
Δa k表示第k个采样点的三轴的加速度差分值，
ax k表示第k个采样点的X轴的加速度，
ax k-1表示第k-1个采样点的X轴的加速度，
ay k表示第k个采样点的Y轴的加速度，
ay k-1表示第k-1个采样点的Y轴的加速度，
az k表示第k个采样点的Z轴的加速度，
az k-1表示第k-1个采样点的Z轴的加速度。
随后，根据各个点的三轴的加速度差分值Δa k，可以得到k点之前的一段时间内的加速度差分值的均值，例如，k之前N个采样点内(即，从k-N到k这N个采样点)的加速度差分值的均值Ma k。
Figure PCTCN2021080794-appb-000001
其中，
Δa i表示从k-N到k这N个采样点中的第i个采样点的三轴的加速度差分值，
Ma k表示k之前N个采样点内的加速度差分值的均值。
那么，通过比较Ma k与Δa k，便可以判断手势的起点和终点。如果Ma k＜＜Δa k则可以认为k点是手势的起点；而如果Ma k＞＞Δa k，则可以认为k点是手势的终点。
这是因为，在用户无手势操作时，手机100a处于相对稳定的状态，各个采样点的Δa k之间的差异不大，各个采样点的Δa k的值连起来将会是一条平缓的曲线，而当用户进行手势操作时，手机会被突然加速，手势操作的起点的Δa k值会激增，那么，Ma k＜＜Δa k。反之，当手势操作结束时，手机会回归相对稳定的状态，Ma k＞＞Δa k。因此，通过，Ma k与Δa k的比较，可以较为容易的判断手势的起点和终点。
在手势起点和手势终点确定后，可以确定手势的持续时间，进而可以得到在X、Y、Z三轴方向上手势持续时间内的平均能量E ax，E ay，E az：
Figure PCTCN2021080794-appb-000002
其中，
L为手势起点到终点的采样点数量，
ax j为手势起点到终点的这段时间中的第j个采样点的X轴加速度值，
ay j为手势起点到终点的这段时间中的第j个采样点的Y轴加速度值，
az j为手势起点到终点的这段时间中的第j个采样点的Z轴加速度值，
E ax为手势起点到终点的这段时间中的X轴加速度信号的平均能量值，
E ay为手势起点到终点的这段时间中的Y轴加速度信号的平均能量值，
E az为手势起点到终点的这段时间中的Z轴加速度信号的平均能量值。
比较X、Y、Z三轴加速度信号的平均能量值E ax，E ay，E az，找出能量值最大的一个轴作为能量最大轴。能量最大轴为X轴则说明手机为左右晃动，能量最大轴为Y轴则说明手机为前后晃动，能量最大轴为Z轴则说明手机为上下晃动。
以X轴为能量最大轴举例，利用从手势起点到终点这L个采样点的每个采样点的加速度值ax，预设手机100a在X轴方向上的加速度的上限阈值和下限阈值，根据加速度值是首先突破上限阈值还是首先突破下限阈值，来判断手机是向左移动还是向右移动。若加速度值首先突破上限阈值，则说明手机100a向左移动，若加速度值首先突破下限阈值，则说明手机100a向右移动。
根据本申请的一些实施例，也可以在L个采样点的持续时间内，遍历各个采样点X轴方向上的加速度值，得到散点波形图，并寻找波峰和波谷，同样预设手机100a加速度的上限阈值和下限阈值，并舍弃低于上限阈值的波峰和高于下限阈值的波谷，判断剩下的波峰波谷的次序，若先出现波峰则说明手机100a为向左移动，否则先出现波谷则说明手机100a向右移动。在这种实施方式中，通过统计上述舍弃操作后剩余的波峰波谷的数量，还可以判断手机100a是否是在摇动。若波峰波谷的数量大于预设的数量阈值，则说明手机100a在摇动，而不是向一个方向移动。
为了提高判断的准确性，可以在手势开始后一段时间(例如，0.2秒)之后再进行阈值的比较和手机100a移动方向的判断，从而避免手势初期的误判。
Y轴为能量最大轴和Z轴为能量最大轴的情况与上述过程类似，在此不再赘述。
通过判断能量最大轴和能量最大轴方向上的加速度值的变化，可以得到手机100a的移动方式，也就是手势操作。得到手机100a的移动方式后，可以通过定义手机100a的移动方式与传输内容和传输方向之间的对应关系，来定义每个手势与要启动的特定操作的映射关系。例如，根据本申请的一些实施例，可以将手机100a的运动分为：左移、右移、前移、后移、上移、下移、摇动等，并分别针对各种运动来确定手机100a与电脑100b之间要传输的内容和内容传输的方向。
表1示出了根据本申请的一些实施例的手机100a的移动与传输内容和传输方向之间的对应关系示例。
表1
Figure PCTCN2021080794-appb-000003
表1所示的手机100a的运动与传输内容和传输方向之间的对应关系仅仅是举例说明，在不同的实施方式中，可以通过与手机100a中的各个应用软件配合，定义各种不同的对应关系。
根据本申请的一些实施例，也可以仅定义传输方向，而不定义传输内容，例如，直接将手机100a与电脑100b的当前的内容(包括：桌面、应用、图片、影音)，从一端到另外一端，互相传递，使所见即所得，保持运行的状态一致。
比如，可以定义前移为手机100a向电脑100b发送内容，而后移则是手机100a从电脑100b 接收内容。那么，在检测到手机100a前移的情况下：如果手机100a在桌面状态(没有打开应用的情况下)，则将手机100a桌面传输到电脑100b上；如果手机100a打开了一个应用，则将界面及运行状态直接迁移、并呈现在电脑100b的屏幕上，并保持运行的状态一致；如果手机100a打开图片或影音后，则将手机100a图片或影音直接迁移、并呈现在电脑100b的屏幕上。
需要注意的是，以上手机100a的移动方向的定义均以手机100a正面朝上且正向持握为基准，如果手机100a被反向持握，那么可能会出现手持手机100a的移动方向与实际传输内容的方向相反的情况。
S11：在手机100a端根据识别到的用户手势确定好传输方向和传输内容后，手机100a可以将确定的传输方向和传输内容发送给电脑100b。
例如，根据表1中示出的对应关系，假设在S10中，识别到手机100a的移动方式为左移，那么，对应的传输方向和传输内容即为：电脑100b的桌面应用程序的界面及运行状态直接迁移、并呈现在手机100a屏幕上。手机100a可以将该传输方向和传输内容发送给电脑100b，以便电脑100b做好将与桌面应用程序的界面及运行状态相关的数据发送给手机100a的准备。
随后，S12：手机100a与电脑100b可以通过蓝牙握手，协商WIFI连接参数，以准备手机100a与电脑100b之间的内容分享。
根据本申请的一些实施例，手机100a与电脑100b之间的内容分享可以通过WIFI直连(WIFI Direct，又称WIFI P2P)来进行，以获取更高的数据传输速度。WIFI直连作为一种点对点连接技术，可以无需额外的接入点(Access Point，AP)的参与，而是在手机100a和电脑100b这两台终端设备之间直接建立TCP/IP连接；其中手机100a和电脑100b中的一台可以作为组拥有者(Group Owner，GO)，起到传统意义上的AP的作用，而手机100a和电脑100b中的另外一台则作为组客户端(Group Client，GC)，以类似于连接AP的方式连接到作为GO的终端设备。
在操作S12中，手机100a与电脑100b协商的WIFI连接参数可以包括WIFI GO的服务集标识符(Service Set Identifier，SSID)和密码。
S13：手机100a与电脑100b根据S12中协商的WIFI连接参数，建立WIFI直连。
S14：通过WIFI将操作S10中确定的传输内容按照操作S10中确定的传输方向从手机100a和电脑100b中的一个传输到另一个。
手机100a与电脑100b之间的内容传输可以采用Miracast投屏技术。手机100a与电脑100b通过WIFI P2P组网后，发送数据的一端作为source端，而接收数据的一段则作为sink端。然后二者可以通过TCP或UDP等传输协议来进行数据的传输，以将source端的内容(包括：桌面、应用、图片、影音等)发送给sink端。在手机100a与电脑100b建立会话后，还可以利用miracast投屏技术中的用户输入反向通道(User Input Back Channel，UIBC)建立功能，建立UIBC，以实现用户在Sink端对Source端的反向控制。
例如，根据表1，在识别到手机100a的移动为右移的情况下，手机100a将与应用程序的界面及运行状态相关的数据发送给电脑100b，手机100a为source端，而电脑100b为sink端。通过Miracast投屏技术，手机100a的应用程序的界面及运行状态将直接迁移、并呈现在电脑100b的屏幕上，并保持电脑100b呈现的状态与手机100a运行的状态一致，而用户可以在电脑100b上通过键盘、鼠标或触控的方式操作手机桌面。
在本申请的实施例中，将蓝牙连接作为控制信道，WIFI连接作为数据信道，以利用WIFI传输数据速度较快的特点，提高内容的分享速度。然而，本领域技术人员应当理解，在一些实施方 式中，也可以不包括S12和S13的操作，而是直接通过蓝牙来传输要分享数据；或者，在另一些实施方式中，手机100a与电脑100b也可以利用其他通信协议来建立其他通信连接，以通过其他方式来传输要分享数据。
S15：传输完成后，手机100a可以判断用户是否要继续分享其它内容，例如，可以利用界面或者声音等输出提示消息，提示用户是否要继续分享。
在用户需要继续分享的情况下(即S15中判断为是)，可以返回到操作S10，再次进行用户手势的识别，并根据识别的用户手势确定传输方向和传输内容，随后继续执行S11和S14的操作，由于手机100a与电脑100b之间已经建立了WIFI连接，所以可以跳过S12和S13的操作。
在用户不需要继续分享的情况下(即S15中判断为否)，该方法可以继续到S16：断开手机100a与电脑100b之间的WIFI连接。
根据本申请的一些实施例，S16的操作可以不在传输完成后就立即执行，而是在传输完成后等待一定的时间后再执行，例如，可以预设等待事件，例如，2分钟，并在完成内容的传输后2分钟无动作的情况下，再执行S16的断开操作。
在上面结合图2介绍的本申请的各种实施例中，手机100a和电脑100b中的控制逻辑可以采用各种架构，例如：分层架构，事件驱动架构，微核架构，微服务架构，或云架构等等。下面以分层架构的系统为例，示例性地说明实现本申请的实施例中提供的内容分享系统的一种具体方案。
图4示出了实现图2所示的内容分享方系统的手机100a和电脑100b的具体结构示例。
如图4所示，可以通过分层架构将控制逻辑分成若干个层，每一层都有清晰的角色和分工。层与层之间可以通过接口进行通信。根据本申请的一些实施例，手机100a和电脑100b的控制逻辑可以分为3层，分别是应用层、驱动层和器件层。
在手机100a和电脑100b中，应用层可以包括一个或多个应用程序包，用以进行内容分享的准备、分享意图的触发、分享意图的校验、分享内容和方向识别的逻辑判断以及数据传输的控制等。其中，分享的准备、分享意图的触发、分享意图的校验、分享内容和方向识别的逻辑判断可以集成为内容分享判定模块，用于进行内容分享的判定，而数据传输模块则可以用于进行数据传输的控制。
如图4所示，手机100a的应用层包括第一内容分享判定模块400和第一数据传输模块414，其中，第一内容分享判定模块400中包括第一分享准备模块401、第一分享意图校验模块406、分享意图触发模块407和传输方向/内容确定模块413。电脑100b的应用层包括第二内容分享判定模块420和第二数据传输模块421，其中第二内容分享判定模块420中包括第二分享准备模块425和第二分享意图校验模块431。上述应用层的各个模块可以通过分别调用下一级模块来实现相应的功能。
具体地，首先，手机100a的第一内容分享判定模块400与电脑100b的第二内容分享判定模块420配合以进行内容分享判定，即图2中的S1-S10的操作。
首先，执行S1：手机100a与电脑100b靠近，通过蓝牙识别对方身份，并进行蓝牙配对建立长连接。
手机100a端：应用层的第一分享准备模块401调用第一蓝牙通信模块402，第一蓝牙通信模块402向驱动层的第一蓝牙驱动模块403发送指令，以调用器件层的第一蓝牙模块404。
电脑100b端：应用层的第二分享准备模块425调用第二蓝牙通信模块426，第二蓝牙通信模块426向驱动层的第二蓝牙驱动模块427发送指令，以调用器件层的第二蓝牙模块428。
第一蓝牙模块404和第二蓝牙模块428分别响应于驱动层的指令，发送蓝牙广播信号，并在手机100a与电脑100b靠近时，彼此通过蓝牙名称等来识别对方身份，进行蓝牙配对以建立蓝牙长连接。
随后，执行S2-S3：建立连接后，两终端设备进行数据传输意图的触发，手机100a通过内部的磁传感器实时监测手机100a的磁感应信号强度。
电脑100b等各种终端设备，本身就是一个复杂的磁场，在电脑100b中，通常会存在大量的磁器件429，在本申请中，磁器件429指的是会带来磁干扰器件。
根据本申请的一些实施例，以笔记本电脑为例，笔记本电脑中通常存在磁传感器，设置在键盘部分(即通常所称的C面)，而相应的，屏幕部分(即通常所称的B面)则通常会有磁器件，以与磁传感器配合来控制电脑休眠或工作。例如，当笔记本电脑屏幕部分与键盘部分闭合时，屏幕部分的磁器件靠近磁传感器，导致磁传感器附近磁场的变化，这使得磁传感器能够感知屏幕状态的变化，并让笔记本电脑通过外围电路和系统进入休眠状态，以降低功耗；而当屏幕打开时，磁器件远离磁传感器，笔记本电脑恢复正常工作。再如，在笔记本电脑的散热风扇中，通常包含定子和转子，而定子和转子也都是磁器件。
根据本申请的一些实施例，为了提高手机100a端的磁感应信号强度的变化强度，也可以在电脑100b中安装额外的磁器件429，或者优化已有的磁器件429，使磁器件429的面积更大或者磁干扰强度更高等。
手机100a端：通过器件层的磁传感器410监测手机100a的磁感应信号强度的变化。磁传感器410的示例包括但不限于，基于霍尔效应的霍尔传感器、基于各向异性磁阻(Anisotropic Magneto Resistance，AMR)效应的AMR传感器等。在各种终端设备中，以AMR传感器为例，AMR传感器可以利用磁阻来测量平面磁场，从而检测出磁场强度以及方向位置，其基本原理是利用各向异性磁致电阻材料感受到微弱的磁场变化时导致自身电阻产生变化。而霍尔传感器则会根据半导体在外围磁场方向产生改变时，会产生电压差的霍尔原理，来检测磁场的变化。
手机100a中的磁传感器410一般用在指南针或是地图导航中，帮助用户实现准确定位，或者用于检测翻盖皮套的开合。在本申请的实施例中，磁传感器410被用来感测周围是否有磁器件靠近。
在手机100a附近出现磁干扰源时，手机100a中的磁传感器410检测到的磁感应信号的强度会剧烈变化，手机100a中的磁传感器410将检测到磁感应信号的上报给驱动层，驱动层的传感器驱动模块409对接收到的磁干扰信号进行处理，以确定磁感应信号的强度，并进一步上报给应用层的磁感应检测模块408，磁感应检测模块408接收到磁感应信号强度的信息后，可以对磁感应信号强度的变化进行分析和判断，判断其是否超过了预设的磁感应信号强度变化阈值，并在超过了预设的磁感应信号强度变化阈值的情况下，向分享意图触发模块407发送信息，以触发分享意图。
随后，S4：为了验证靠近手机100a的到底是与手机100a长连接的电脑100b，还是其他磁干扰源，手机100a可以进行分享意图的校验。
手机100a端：应用层的第一分享意图触发模块407向第一分享意图校验模块406发送分享意图触发信息，第一分享意图校验模块406向第一蓝牙测距模块405发送第一校验指令，启动第一蓝牙测距模块405，应用层中的第一蓝牙测距模块405响应于收到的第一校验指令，向第一蓝牙驱动模块403发送信号，以通过第一蓝牙驱动模块403来控制第一蓝牙模块404发送蓝牙广播信 号。
S5-S6：电脑100b根据接收到的蓝牙信号的强度，确定自己与手机100a之间的距离，并将确定的距离与预设阈值进行比较，判断自己与手机100a之间的距离是否小于预设的距离阈值。
电脑100b端：第二蓝牙模块428收到手机100a发送的蓝牙广播信号后，可以将收到的蓝牙信号上报给驱动层的第二蓝牙驱动模块427，第二蓝牙驱动模块427随后可以对第二蓝牙模块428发来的数据进行处理，以确定蓝牙信号的强度等，并将蓝牙信号的强度上报给应用层的第二蓝牙测距模块430，使电脑100b的第二蓝牙测距模块430可以根据接收到的蓝牙信号的强度，确定自己与手机100a之间的距离，例如，可以利用前述公式(1)来确定自己与手机100a之间的距离。
第二蓝牙测距模块430将确定好的距离上报给第二分享意图校验模块431，第二分享意图校验模块431判断自己与手机100a之间的距离是否小于预设的距离阈值。
根据本申请的一些实施例，在电脑100b端执行距离判断时，可以同时执行S7：也开启蓝牙广播，使手机100a和电脑100b两端都开启距离校验。
电脑100b的应用层中的第二分享意图校验模块431向第二蓝牙测距模块430发送第二校验指令，第二蓝牙测距模块430响应于第二校验指令，向第二蓝牙驱动模块427发送指令，以通过前述第二蓝牙驱动模块427来控制第二蓝牙模块428发送蓝牙广播信号。
S8-S9：在手机100a端，手机100a也可以根据接收到的来自电脑100b的蓝牙信号的强度，确定自己与电脑100b之间的距离，并判断自己与电脑100b之间的距离是否小于预设的距离阈值。
具体地，手机100a端：第一蓝牙模块404收到电脑100b发送的蓝牙广播信号后，将收到的蓝牙信号上报给驱动层的第一蓝牙驱动模块403，第一蓝牙驱动模块403可以对第一蓝牙模块404发来的数据进行处理，以确定蓝牙信号的强度等，并将蓝牙信号的强度上报给应用层的第一蓝牙测距模块405，使手机100a中的第一蓝牙测距模块405可以根据接收到的蓝牙信号的强度，利用前述公式(1)判断判断自己与电脑100b之间的距离。
这样，手机100a和电脑100b这两个终端设备通过双重校验，提高距离监测的准确性。在手机100a中的第一分享意图校验模块406与电脑100b中的第二分享意图校验模块431都测得手机100a与电脑100b之间的距离小于预设阈值的情况下，可以认为手机100a端的磁干扰事件并不是其他磁干扰源带来的误触发，而确实是由于手机100a与电脑100b靠近，由电脑100b中的磁器件429带来的磁干扰。
当然，在一些其他实施例中，手机100a与电脑100b间距离的测量也可以采用其他方案进行，例如，前文所述的蓝牙单端测距，毫米波测距、超声波测距等。
随后，S10：手机100a开始识别用户手势，以根据用户手势确定要传输的内容和传输的方向。
根据本申请的一些实施例，如上文结合图2所述，传输内容和方向的识别通过识别用户手势来确定，而用户的手势则可以通过检测手机100a的移动方式来判断。在一些实施方式中，可以预先设定手势与要启动的特定操作的映射关系(例如上文中的表1)，并将该映射关系预先存储在手机100a中。
手机100a的移动方式(如左移、右移等等)可以通过手机100a中的重力传感器411来确定。重力传感器411又称重力感应器，它的一种实现方式是采用弹性敏感元件制成悬臂式位移器，与采用弹性敏感元件制成的储能弹簧来驱动电触点，完成从重力变化到电信号的转换。重力传感器411在手机、平板电脑等各种便携式计算设备中有着广泛的应用，例如，可以用于识别手机100a姿态或移动方式，应用于横竖屏切换，计步器等应用。在手机100a等各种终端设备中，常见的重 力传感器包括但不限于：博世的BMA系列，意法半导体(ST)的LIS3X系列等。
通过手机100a中的重力传感器411来确定手机100a的移动的具体方式如下：
在手机100a端：应用层的中传输方向/内容确定模块413向手势识别模块412发送手势识别指令。手势识别模块412响应于收到手势识别指令，向驱动层的传感器驱动模块409发送信号，以使传感器驱动模块409开启器件层的重力传感器411。
重力传感器411检测手机100a在各个方向上(一般为三轴)加速度的大小，进而将加速度数据上报给驱动层的传感器驱动模块409，传感器驱动模块409对接收到的加速度数据进行处理，计算得到加速度值以及方向等，并上报给应用层的手势识别模块412。
手势识别模块412利用测得的加速度值以及方向等生成加速度变化矢量，进而得到手机100a的移动，并将手机100a的移动上报给传输方向/内容确定模块413。
使得传输方向/内容确定模块413可以根据手机100a的移动，对照表1确定传输内容和传输方向。举例来说，假设手机100a的手势识别模块412测得的手机的移动是右移，传输方向/内容确定模块413可以根据表1确定该移动对应的是：手机100a的应用程序的界面及运行状态直接迁移、并呈现在电脑100b的屏幕上。即，传输方向是手机100a到电脑100b，而传输的内容是手机100a的应用程序的界面及运行状态。
在本申请的一些实施例中，也可以通过其他方式来判断手机100a的运动，其他方式包括但不限于：利用线性加速度计、陀螺仪传感器或者定位系统等。例如，陀螺仪传感器可以确定手机100a围绕三个轴(即，x，y和z轴)的角速度，因此，陀螺仪传感器同样可以用于判断手机100a的移动。或者，在一些实施方式中，也可以通过线性加速度计、陀螺仪传感器以及重力传感器等的组合来判断手机100a的运动，进而确定用户的手势。
S11：在手机100a端确定好传输方向和传输内容后，将确定的传输方向和传输内容发送给电脑100b，该信息的发送仍然可以通过蓝牙信道传输。
手机100a端：应用层中的传输方向/内容确定模块413将确定好的传输方向(即手机100a到电脑100b)和传输内容(即手机100a的应用程序的界面及运行状态)发送给第一数据传输模块414，第一数据传输模块414向第一蓝牙通信模块402发送通信指令，使第一蓝牙通信模块402通过驱动层的第一蓝牙驱动模块403驱动第一蓝牙模块404，将确定的传输方向和传输内容发送给电脑100b。
电脑100b端：第一蓝牙模块428收到手机100a发来的信息后，将收到的信息通过第二蓝牙驱动模块427上报给第二蓝牙通信模块426，第二蓝牙通信模块426处理收到的信息，获取传输方向和传输内容，并上报给第二数据传输模块421，以使电脑100b获取到手机100a确定的传输方向和传输内容。
随后，S12：手机100a与电脑100b通过蓝牙握手，协商WIFI连接参数。
以手机100a作为WIFI直连的GO为例，手机100a端：应用层的第一数据传输模块414向第一蓝牙通信模块402发送通信指令，使第一蓝牙通信模块402通过驱动层的第一蓝牙驱动模块403驱动第一蓝牙模块404，将手机100a作为GO的SSID和密码发送给电脑100b。
电脑100b端：器件层的第一蓝牙模块428收到手机100a发来的信息后，将收到的信息通过第二蓝牙驱动模块427上报给第二蓝牙通信模块426，第二蓝牙通信模块426处理收到的信息，获取GO的SSID和密码，并上报给第二数据传输模块421。
S13：手机100a与电脑100b根据S12中协商的WIFI连接参数，建立WIFI连接。
手机100a端：第一数据传输模块414向第一WIFI通信模块415发送通信指令，使第一WIFI通信模块415通过驱动层的第一WIFI驱动模块416驱动第一WIFI模块417，开启WIFI直连功能。
电脑100b端：第二数据传输模块421向第二WIFI通信模块422发送通信指令，使第二WIFI通信模块422通过驱动层的第二WIFI驱动模块423驱动第二WIFI模块424，开启WIFI直连功能，并通过操作S12中获取的SSID和密码与手机100a建立WIFI连接。
随后，S14：通过WIFI将手机100a的应用程序的界面及运行状态通过手机100a与电脑100b之间的WIFI通信链接发送给电脑100b。
在本申请的实施例中，将蓝牙连接作为控制信道，WIFI连接作为数据信道，以利用WIFI传输数据速度较快的特点，提高内容的分享速度。然而，本领域技术人员应当理解，在一些实施方式中，也可以不包括S12和S13的操作，而是直接通过蓝牙来传输要分享数据；或者，在另一些实施方式中，手机100a与电脑100b也可以利用其他通信协议来建立其他通信连接，以通过其他方式来传输要分享数据。
以上结合图2和图4说明了根据本申请的实施例的内容分享的具体过程的示例，本领域技术人员应当理解，其中的许多操作可以被并行地、并发地或者同时实施，此外，各项操作的顺序也可以被重新安排。
另外，图4中所示的具体器件和模块等都是举例说明，并不构成对本申请的限制。在本申请的其他实施例中，也可以采用不同的器件和模块以其他方式来实现本身请的内容分享方案。
例如，手机100a执行手势识别时，可以将图4中的重力传感器411替换其他器件，例如线性加速度传感器、陀螺仪等；或者，在一些实施方式中，也可以通过多个器件的组合来实现手机100a的移动检测。
再如，在进行分享意图的校验时，第一分享意图校验模块406和/或第二分享意图校验模块431也可以通过除了蓝牙模块之外的其他器件来进行测距。例如，第一分享意图校验模块406和/或第二分享意图校验模块431可以通过驱动层调用手机100a超声波模块、毫米波模块等来实现测距操作。
此外，图2和图4中示出的一些操作也可以采用其他方案来实现。例如，手机100a所执行的操作S10：识别用户手势，根据用户手势确定要传输的内容和传输的方向，该操作中，用户的手势也可以不是用户手持手机100a的移动，而是其他手势操作。
根据本申请的另一些实施例，例如，在手机100a包括触摸屏的情况下，用户的手势也可以是用户施加在手机100a的触摸屏表面的滑动、拖动、点击或者长按等触摸操作，在这种情况下，可以通过识别手机100a的触摸输入(如左滑、右滑、长按等等)来判断用户的手势，并且每个手势可以被映射到要启动的特定操作。
在该实施例中，手机100a的触摸屏可以是各种类型的触摸屏，例如电容式触摸屏、电阻式触摸屏、红外线式触摸屏、表面声波式触摸屏或其他类型的触摸屏等。可以利用手机100a的触摸屏来接收用户的触摸操作。触摸屏可以包括触摸传感器与显示屏，触摸传感器，也称“触控器件”，在一些实施例中，触摸传感器可以被设置于显示屏上，用于检测作用于其上或附近的触摸操作。触摸传感器可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。
根据本申请的一些实施例，S10：手机100a开始识别用户手势时，手机100a端：应用层的中传输方向/内容确定模块413向手势识别模块412发送手势识别指令。手势识别模块412响应于收到手势识别指令，向驱动层的传感器驱动模块409发送信号，以使传感器驱动模块409开启器件 层的触摸传感器。
触摸传感器接收用户作用于手机100a的触摸屏上的触摸操作。例如，在用户的手指贴近或接触具有触摸屏功能的手机100a时，手机100a的触摸传感器检测作用于手机100a的触摸屏上的操作，进而将触摸数据上报给驱动层的传感器驱动模块409。手机100a驱动层的传感器驱动模块409可以对触摸屏中的触摸传感器上报的数据进行处理，识别点击、滑动、长按等操作，并计算这些操作的坐标信息，生成时间戳等，并将包含操作类型、坐标信息、时间戳等的输入事件上报给应用层的手势识别模块412，进而手势识别模块412可以根据预设的触摸操作与传输的内容和方向的映射关系(例如下表2示出的映射关系)，判断传输的内容和方向。
表2示出了根据本申请的一些实施例的作用于手机100a的触摸操作与传输内容和传输方向之间的映射关系示例。
表2
Figure PCTCN2021080794-appb-000004
此外，根据本申请的一些实施例，用户的手势也可以包括其他类型，例如可以作用于手机100a，但与手机100a的屏幕间隔一定距离的手势操作(例如，悬浮触控)等。另外，在一些实施例中，也可以采用触控笔等其他输入设备来输入手势。
此外，虽然在图2和图4中，是以手机100a和电脑100b之间分享内容为例说明了终端设备间的内容分享过程，但是，应当理解，本申请的实施例所提供的内容分享方案可以应用在各种终端设备之间，例如手机与手机之间，智能手表与手机之间，手环与电脑之间等等。
本申请的实施例中提供的内容分享方案，简化了数据传输的过程，并且相比于NFC触碰等方式只能应用于非常短的传输距离，本申请提供的内容分享方案可以用于相对长一些的距离情况，此外，借助于手势识别来确定传输方向和传输内容，实现了两个设备间的双向传输，同时能够有效地避免传输方向出错。
下面以手机为例结合图5说明本申请的终端设备100的一种具体结构示例。在一些实施例中，图5所示的设备可以是手机100a或者可以被包括在手机100a中。

在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。可以理解的是，本申请实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对终端设备100的结构限定。在本申请另一些实施例中，终端设备100也可以采用上述实施例中不同的接口连接方式，或多种接口连接方式的组合。
传感器模块180可以包括磁传感器180D，磁传感器180D的示例包括但不限于，基于霍尔效应的霍尔传感器、基于各向异性磁阻(Anisotropic Magneto Resistance，AMR)效应的AMR传感器等。在终端设备100中，以AMR传感器为例，AMR传感器可以利用磁阻来测量平面磁场，从而检测出磁场强度以及方向位置，其基本原理是利用各向异性磁致电阻材料感受到微弱的磁场变化时导致自身电阻产生变化。而霍尔传感器则会根据半导体在外围磁场方向产生改变时，会产生电压差的霍尔原理，来检测磁场的变化。
终端设备100中的磁传感器180D一般用在指南针或是地图导航中，帮助用户实现准确定位，或者用于检测翻盖皮套的开合。在一些实施例中，当终端设备100是翻盖机时，终端设备100可以根据磁传感器180D检测翻盖的开合，进而根据检测到的皮套的开合状态或翻盖的开合状态，设置翻盖自动解锁等特性。
在本申请的一些实施例中，终端设备100可以利用磁传感器180D来感测周围是否有磁器件靠近。
加速度传感器180E可检测终端设备100在各个方向上(一般为三轴)加速度的大小。当终端设备100静止时可检测出重力的大小及方向。还可以用于识别终端设备100姿态或移动，应用于横竖屏切换，计步器等应用。
根据本申请的一些实施例，加速度传感器180E可以包括重力传感器，重力传感器又称重力感应器，它的一种实现方式是采用弹性敏感元件制成悬臂式位移器，与采用弹性敏感元件制成的储能弹簧来驱动电触点，完成从重力变化到电信号的转换。重力传感器在手机、平板电脑等各种便携式计算设备中有着广泛的应用，在各种终端设备100中，常见的重力传感器包括但不限于：博世的BMA系列，意法半导体(ST)的LIS3X系列等。
重力传感器能够感知到加速度的变化，进而通过加速度值来判断终端设备100的运动，比如倾斜、左右晃动、上升、下降等。终端设备100中的重力传感器通常为三轴结构，重力传感器通过三轴可以感知任意方向上的加速度，判断终端设备100的空间运动。重力传感器在进行三轴的加速度运算时，重力感应坐标可以是相对于终端设备100而言，而不是空间坐标。
陀螺仪传感器180B可以用于确定终端设备100的运动姿态。在一些实施例中，可以通过陀螺仪传感器180B确定终端设备100围绕三个轴(即，x，y和z轴)的角速度。陀螺仪传感器180B同样可以用于判断设备的移动。示例性的，其可以用于拍摄防抖，当按下快门，陀螺仪传感器180B检测终端设备100抖动的角度，根据角度计算出镜头模组需要补偿的距离，让镜头通过反向运动抵消终端设备100的抖动，实现防抖。陀螺仪传感器180B还可以用于导航，体感游戏场景。
