具体地，所述运动数据主要包括由加速度传感器获取的加速度数据，当然也还可以包括其他转化而来的数据。当移动终端静止时，加速度计传感器只受重力影响，因此可以认为此时加速度数据即为重力分量。
步骤S200，将所述运动数据与预设数据进行对比，其中，所述预设数据为体感拨号的操作特征数据。
在获取到移动终端的运动数据之后，再将所述运动数据与预设数据进行对比。
在本实施例中，预设数据即为为体感拨号的操作特征数据，也就是能够反映体感拨号动作特征的运动数据。经研究发现进行体感拨号动作的运动数据与其他可能触发体感拨号的动作相比，具有一些明显的特征，因此通过将获取到的移动终端的运动数据与预设的体感拨号数据进行对比分析，就可以通过运动数据识别出体感拨号动作。
具体地，移动终端可以先比较所述运动数据和预设数据的变化趋势，若变化趋势相同，则再比较相应的特征数值。当然，移动终端也可以将运动数据和预设数据一一进行比较，或者根据预设的算法将运动数据和预设数据进行计算，由此得到对比结果，具体实施中可以根据实际需要进行灵活设置。
步骤S300，若所述运动数据与所述预设数据匹配，则启动体感拨号功能。
在将所述运动数据与预设数据进行对比之后，若两者匹配，则移动终端启动体感拨号功能。
具体地，以比较所述运动数据和预设数据的变化趋势和数值进行说明。如果获取到的运动数据和预设数据的变化趋势和数值完全相同，或者两者变化趋势大致相同，且相应的特征数值之间的差值在规定的范围之内，就可以认为运动数据和预设数据匹配，此时移动终端启动体感拨号功能。当 然，具体实施中还可以采用其他匹配规则和匹配方法，比如通过数学模型计算所述运动数据和预设数据的匹配程度，若计算结果显示两者的匹配程度在合适范围内，则启动体感拨号功能，可根据实际需要进行灵活设置。
在本实施例中，通过获取移动终端的运动数据；将所述运动数据与预设数据进行对比；若所述运动数据与所述预设数据匹配，则启动体感拨号功能。通过上述方式，本实施例根据体感拨号动作的运动数据与其他可能触发体感拨号的动作相比，具有明显特征的现象，通过加速度传感器获取移动终端的运动数据，再将所述运动数据与预设体感拨号的数据进行对比，从而识别出能够反映体感拨号动作特征的运动数据，并启动体感拨号功能，实现对体感拨号功能的有效控制。本实施例能够有效地降低体感拨号的误识别率，同时由于本发明实施例根据能够反映体感拨号动作特征的运动数据启动体感拨号功能，因此无需考虑应用场景，从而能够满足用户在各种场景下进行体感拨号的需求，提升用户体验。
进一步地，参照图2，图2为图1中将所述运动数据与预设数据进行对比的细化流程示意图。基于本发明体感拨号的控制方法第一实施例，步骤S200可以包括：
步骤S210，获取所述运动数据的变化趋势。
步骤S220，根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态。
步骤S230，若所述移动终端处于左手操作状态，则将所述运动数据与预设数据中左手数据进行对比。
步骤S240，若所述移动终端处于右手操作状态，则将所述运动数据与预设数据中右手数据进行对比。
在本实施例中，首先，移动终端获取运动数据的变化趋势，根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态。
具体地，移动终端可以先根据运动数据得到相应的数据波形，根据数据波形来获取运动数据的变化趋势。根据加速度传感器的工作原理，用户在进行左手操作和右手操作时，加速度传感器采集到的加速度数据呈现相反的变化趋势，比如前者的波形处于波峰时，后者的波形正好处于波谷，前者达到最大值时，后者达到最小值。由于左手操作和右手操作的运动数据的变化趋势具有明显的差别，因此可以根据运动数据的变化趋势先判断出用户正在进行左手操作还是右手操作。
需要说明的是，移动终端也可以不通过运动数据的变化趋势来判断用户正在进行左手操作还是右手操作，比如，移动终端可以直接检测一段时间内采集到的运动数据是正值还是负值，通过正负值的区别来判断用户正在进行左手操作还是右手操作。
然后，移动终端根据左右手的判断结果将所述运动数据与对应的预设数据进行对比。若移动终端处于左手操作状态，则对比左手操作状态下相应的预设数据；反之，若移动终端处于右手操作状态，则对比右手操作状态下相应的预设数据，由此得到对比结果。在更多的实施中也可以不判断所述移动终端处于左手操作状态还是右手操作状态，直接将运动数据与预设的左右手操作状态下的预设数据进行对比，判断所述运动数据的变化趋势是否与左手或右手对应的预设数据的变化趋势相同，得到对比结果。
在本实施例中，通过获取移动终端的运动数据；获取所述运动数据的变化趋势；根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；若所述移动终端处于左手操作状态，则将所述运动数据与预设数据中左手数据进行对比；若所述移动终端处于右手操作状态，则将所述运动数据与预设数据中右手数据进行对比；若所述运动数据与所述预设数据匹配，则启动体感拨号功能。通过上述方式，由于用户在进行左手操作和右手操作时，加速度传感器采集到的加速度数据呈现相反的变化趋势， 因此可以根据运动数据的变化趋势先判断出用户正在进行左手操作还是右手操作，再对比对应的操作状态下的运动数据和预设数据，从而有效地提高了对比的效率。
进一步地，参照图3，图3为本发明体感拨号的控制方法第二实施例的流程示意图。基于上述图2所示的实施例，所述步骤S230可以包括：
步骤S231，获取所述左手操作状态下的运动数据的最小值和第一终值。
步骤S232，将所述最小值和第一终值分别与预设负值和第一预设范围进行对比。
所述步骤S300可以包括：
步骤S310，若所述最小值小于预设负值，且所述第一终值在第一预设范围之内，则启动体感拨号功能。
所述步骤S240可以包括：
步骤S241，获取所述右手操作状态下的运动数据的最大值和第二终值。
步骤S242，将所述最大值和第二终值分别与预设正值和第二预设范围进行对比。
所述步骤S300还可以包括：
步骤S320，若所述最大值大于预设正值，且所述第二终值在第二预设范围之内，则启动体感拨号功能。
在本实施例中，在判断出移动终端处于左手操作状态还是右手操作状态之后，再将相应操作状态下的运动数据和对应的预设数据进行进一步的对比分析。具体地，移动终端获取对应的操作状态下的运动数据的极值和终值，将所述极值和终值分别与对应的预设数据进行对比。
移动终端的运动数据由加速度传感器检测，由数据采集系统采集。加速度传感器可以检测在x、y、z三轴的加速度数据，经过大量的样本分析，对于拨打电话的动作，数据集呈现出明显的特征，可以与其它干扰动作形 成明显的对比，此处仅以加速度计传感器x轴上的数据为例进行说明，对于其它轴的数据可以按照类似的方法提取，具体特征如下：
左手拨打电话：
刚开始的数据为一个正值，且变化平缓，经过短暂的时间后，会呈现一个小的波峰，之后数据快速衰减到一个最小值，该最小值一定小于某一负值，之后数据会有轻微的上升趋势，但由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值会有一定的取值范围。
右手拨打电话：
该过程呈现的数据变化与左手拨打电话的相反，刚开始的数据为一个负值，且变化平缓，经过短暂时间后，会出现一个小的波谷，之后数据快速上升到一个最大值，该最大值一定大于某一正值，之后数据会有轻微的下降趋势，但由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值也会存在一个取值范围。
对于其它可能导致误触的操作，此处仅以几例来说明其数据波形与正常拨打电话的区别：
手机从右手换到左手：
数据集刚开始的变化与左手拨打电话非常相似，但数据不会衰减到一个非常明显的负值，并且很多情况下，数据很长的拖尾，即在数据变化的末端，数据反复呈现出波峰和波谷。
将手机放到口袋中：
对于放左边口袋和右边的口袋，数据变化虽然不一样，但是都有明显的特征，即只在正值范围内变化或只在负值内变化。
右手挥舞手机靠近墙壁：
数据集刚开始的变化与右手拨打电话非常相似，但数据达到最大值后会有很长的拖尾而不会很快被截断。
根据以上描述，其他可能导致误触的动作与体感拨号动作的运动数据特征存在明显的不同，因此可以根据这些特征对运动数据进行定量分析。具体地，若移动终端处于左手操作状态，则可以在在数据的快速下降阶段获取所述运动数据的极小值，该极小值也是最小值，且一定小于某一负值；由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值一定在预设范围之内。若所述最小值小于预设负值，且所述终值在预设范围之内，则可以认为所述运动数据和预设数据匹配，并启动体感拨号功能。反之，若移动终端处于右手操作状态，则可以在数据的快速上升阶段获取所述运动数据的极大值，该极大值也是最大值，且一定大于某一正值；由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值也一定在预设范围之内。若所述最大值大于预设正值，且所述终值在预设范围之内，则可以认为所述运动数据和预设数据匹配，并启动体感拨号功能。
在本实施例中，通过获取移动终端的运动数据；获取所述运动数据的变化趋势；根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；获取所述左手操作状态下的运动数据的最小值和第一终值；将所述最小值和第一终值分别与预设负值和第一预设范围进行对比；若所述最小值小于预设负值，且所述第一终值在第一预设范围之内，则启动体感拨号功能；获取所述右手操作状态下的运动数据的最大值和第二终值；将所述最大值和第二终值分别与预设正值和第二预设范围进行对比；若所述最大值大于预设正值，且所述第二终值在第二预设范围之内，则启动体感拨号功能。由于用户在进行左右手操作时会有各种不同的动作，而每种动作所对应的运动数据不同，本实施例通过定量的分析运动数据是否与预设的体感拨号数据匹配，从而识别出体感拨号动作，能够有效降低体感拨号的误识别率，满足用户在各种场景下进行体感拨号的需求，提升用户体验。
进一步地，参照图4，图4为本发明体感拨号的控制方法第三实施例的流程示意图，基于上述图2所示的实施例，在所述步骤S210之前，还可以包括：
步骤S201，根据所述运动数据确定所述移动终端在静止时的空间姿态；
步骤S210则替换为：若所述移动终端在静止时的空间姿态为预设空间姿态，则执行步骤：获取所述运动数据的变化趋势。
在本实施例中，为进一步提高识别效率，在获取所述运动数据的变化趋势之前，可以先根据运动数据判断移动终端在静止时的空间姿态是否为预设的体感拨号的空间姿态，若是，则获取所述运动数据的变化趋势。
具体地，移动终端处于静止时会有各种不同的空间姿态，比如水平放置、竖直放置、倾斜放置等等。正常拨打电话时，移动终端处于静止状态且有一定的倾斜度，因此运动数据集的初始阶段变化缓慢且平稳，利用移动终端倾斜时在加速度敏感轴上的变化，即所谓的重力感应，可以感应倾斜角，该倾斜角应该在预设的范围之内，由此，通过对运动数据的简要分析就可以快速过滤掉一些不属于体感拨号的情况。
在本实施例中，通过获取移动终端的运动数据；根据所述运动数据确定所述移动终端在静止时的空间姿态；若所述移动终端在静止时的空间姿态为预设空间姿态，则获取所述运动数据的变化趋势；根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；获取对应的所述操作状态下的所述运动数据的极值和终值；将所述极值和终值分别与对应的预设数据进行对比；若所述运动数据与所述预设数据匹配，则启动体感拨号功能。由于静止时移动终端加速度传感器的数据只受重力影响，因此可以认为此时加速度传感器的数据就表示重力分量，因此经过简单的姿态转换可以得到移动终端此刻的姿态，并与正常拨打电话的姿态范围进行比较，快速过滤掉异常情况，从而提高算法的效率。
进一步地，参照图5，图5为本发明体感拨号的控制方法第四实施例的流程示意图。基于上述图1所示的实施例，所述步骤S100之前，还可以包括：
步骤S10，建立数据缓冲区，所述数据缓冲区用于存储当前预设连续时间内的运动数据。
此时步骤S100可以替换为：
步骤S110，获取所述数据缓冲区中的运动数据。
在本实施例中，移动终端可以建立一个数据缓冲区，用来存储当前预设连续时间内的运动数据，减少存储实时获取到的运动数据的存储空间，然后获取所述数据缓冲区中的运动数据。
作为一种实施方式，在加速度传感器实时获取移动终端的加速度数据的情况下，数据缓冲区始终保存的是用户最近连续操作的一段数据，以保证当采集的运动数据大于缓冲区大小时依然能有效工作。一般地，用户体感拨号动作的持续时间为1s到2s，数据缓冲区存储当前一段时间内的加速度数据。在检测到移动终端处于静止状态时，数据分析系统逆序复制所述数据缓冲区的数据，并对数据进行分析。由于数据分析系统在复制数据时采用的是逆序方式，即数据分析系统保存的数据是从耳边静止到远端开始运动的数据集，这种方式可以更高效的提取波形变化特征。
需要说明的是，数据缓冲区的大小可以根据拨号时间灵活设置，在复制数据缓冲区的运动数据时，也可以不采用逆序的方式，比如，可以采用正序的方式复制所述数据缓冲区中的运动数据，在进行数据分析时采用逆序分析，具体实施中可以根据实际需要进行灵活设置。
进一步地，所述步骤S110之前，还可以包括：
步骤S101，通过距离传感器获取移动终端的距离数据。
步骤S102，根据所述距离数据判断所述移动终端是否处于接近状态；
步骤S110则替换为：若移动终端处于接近状态，则执行步骤：获取所述数据缓冲区中的运动数据。
在本实施例中，为进一步提高识别效率，在获取数据缓冲区的运动数据之前，可以通过距离传感器获取移动终端的距离数据，再根据所述距离数据判断所述移动终端是否处于接近状态，若是，则执行步骤：获取所述数据缓冲区中的运动数据。
本实施例利用拨打电话需要靠近耳边这一特征，结合使用距离传感器，数据采集系统将只保留最能反应拨打电话的特征的运动数据集。移动终端的运动过程可以包括运动接近和运动远离，这两种情况下数据采集系统都要采集运动数据；在移动终端处于静止状态时，通过距离传感器获取移动终端的距离数据，从而可以判断出移动终端是运动接近还是运动远离。在移动终端静止时，若移动终端处于远离状态，则直接清除刚刚采集到的运动数据；若移动终端处于接近状态，则获取数据缓冲区中的运动数据，再对所述运动数据进行进一步分析。
参照图6，图6为本发明体感拨号的控制方法第四实施例的应用场景示意图。移动终端建立一个数据缓冲区，用来存储当前预设连续时间内的运动数据，然后数据分析系统获取所述数据缓冲区中的运动数据。具体实施方式如下：
首先，加速度传感器检测移动终端是否处于运动状态，只有在检测到移动终端处于运动状态时，数据采集系统才会收集数据，即将t时刻数据添加到数据缓冲区中。接着，距离传感器再检测移动终端是否处于接近状态，若移动终端不处于接近状态，则清理数据缓冲区中的数据。只有在移动终端处于接近状态时，才会启动数据分析系统对数据进行进一步分析。
参照图7，图7为图6中数据分析系统处理数据的具体流程示意图。以移动终端为手机进行说明。在手机处于静止且接近状态时，数据采集系统 逆序复制缓冲区中的运动数据，并对数据进行平滑处理，通过读取初始数据分析手机静止时的状态，判断手机的空间姿态是否满足要求，若是，则再判断用户是左手还是右手拨打电话。若是左手拨号，则对数据波形依次进行平缓区间检测、波峰检测、快速衰减阶段检测、最小值检测和终止值检测，其中，最小值检测和终止值检测对应第二实施例中最小值和第一终值的处理过程；若是右手拨号，则对数据波形依次进行平缓区间检测、波谷检测、快速上升阶段检测、最大值检测和终止值检测，其中最大值检测和终止值检测对应第二实施例中最大值和第二终值的处理过程。最后，返回识别结果。
本发明实施例还提出一种计算机可读存储介质，该存储介质包括一组指令，所述指令用于执行以上任一实施例所述的体感拨号的控制方法。
在本实施例中，通过建立数据缓冲区，所述数据缓冲区用于存储当前预设连续时间内的运动数据；通过距离传感器获取移动终端的距离数据；根据所述距离数据判断所述移动终端是否处于接近状态；若是，则获取所述数据缓冲区中的运动数据；将所述运动数据与预设数据进行对比；若所述运动数据与所述预设数据匹配，则启动体感拨号功能。本实施例通过建立数据缓冲区，配合使用距离传感器，只有在移动终端处于静止且接近状态时，才对数据缓冲区中的运动数据进行进一步分析，可以有效的减少分析的数据量，减少数据干扰，在很大程度上提升了体感拨号识别的效率。
本发明实施例还提供一种体感拨号的控制装置。
参照图8，图8为本发明体感拨号的控制装置第一实施例的功能模块示意图。所述装置包括：
第一获取模块100，配置为获取移动终端的运动数据。
在本实施例中，所述移动终端可以包括智能手机、平板电脑等具有体感拨号功能的设备。移动终端内置加速度传感器，第一获取模块100通过 加速度传感器实时采集移动终端的运动数据。
具体地，所述运动数据主要包括由加速度传感器获取的加速度数据，当然也还可以包括其他转化而来的数据。当移动终端静止时，加速度计传感器只受重力影响，因此可以认为此时加速度数据即为重力分量。
对比模块200，配置为将所述运动数据与预设数据进行对比，其中，所述预设数据为体感拨号的操作特征数据。
在第一获取模块100获取到移动终端的运动数据之后，对比模块200再将所述运动数据与预设数据进行对比。
在本实施例中，预设数据即为体感拨号的操作特征数据，也就是能够反映体感拨号动作特征的运动数据。经研究发现进行体感拨号动作的运动数据与其他可能触发体感拨号的动作相比，具有一些明显的特征，因此通过对比模块200将获取到的移动终端的运动数据与预设的体感拨号数据进行对比分析，就可以通过运动数据识别出体感拨号动作。
具体地，对比模块200可以先比较所述运动数据和预设数据的变化趋势，若变化趋势相同，则再比较相应的特征数值。当然，对比模块200也可以将运动数据和预设数据一一进行比较，或者根据预设的算法将运动数据和预设数据进行计算，由此得到对比结果，具体实施中可以根据实际需要进行灵活设置。
控制模块300，配置为若所述运动数据与所述预设数据匹配，则启动体感拨号功能。
在对比模块200将所述运动数据与预设数据进行对比之后，若两者匹配，则移动终端启动体感拨号功能。
具体地，以比较所述运动数据和预设数据的变化趋势和数值进行说明。如果控制模块300获取到的运动数据和预设数据的变化趋势和数值完全相同，或者两者变化趋势大致相同，且相应的特征数值之间的差值在规定的 范围之内，就可以认为运动数据和预设数据匹配，此时移动终端启动体感拨号功能。当然，具体实施中还可以采用其他匹配规则和匹配方法，比如通过数学模型计算所述运动数据和预设数据的匹配程度，若计算结果显示两者的匹配程度在合适范围内，则启动体感拨号功能，可根据实际需要进行灵活设置。
在本实施例中，第一获取模块100获取移动终端的运动数据；对比模块200将所述运动数据与预设数据进行对比；若所述运动数据与所述预设数据匹配，则控制模块300启动体感拨号功能。由于体感拨号动作的运动数据与其他可能触发体感拨号的动作相比，具有一些明显的特征，比如数据的变化趋势和数值存在明显的差异，本发明实施例通过第一获取模块100获取移动终端的运动数据，再通过对比模块200和控制模块300将所述运动数据与预设体感拨号的数据进行对比和匹配，从而识别出最能反映体感拨号动作特征的数据，并启动体感拨号功能，实现对体感拨号功能的有效控制。本实施例能够有效地降低体感拨号的误识别率，同时由于本发明实施例根据能够反映体感拨号动作特征的运动数据启动体感拨号功能，因此无需考虑应用场景，从而能够满足用户在各种场景下进行体感拨号的需求，提升了用户体验。
进一步地，参照图9，图9为图8中对比模块的细化功能模块示意图。所述对比模块200包括：
获取单元210，配置为获取所述运动数据的变化趋势；
判断单元220，配置为根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；
第一对比单元230，配置为若所述移动终端处于左手操作状态，则将所述运动数据与预设数据中左手数据进行对比；
第二对比单元240，配置为若所述移动终端处于右手操作状态，则将所 述运动数据与预设数据中右手数据进行对比。
在本实施例中，首先，获取单元210获取运动数据的变化趋势，判断单元220根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态。
具体地，获取单元210可以先根据运动数据得到相应的数据波形，根据数据波形来获取运动数据的变化趋势。根据加速度传感器的工作原理，用户在进行左手操作和右手操作时，加速度传感器采集到的加速度数据呈现相反的变化趋势，比如前者的波形处于波峰时，后者的波形正好处于波谷，前者达到最大值时，后者达到最小值。由于左手操作和右手操作的运动数据的变化趋势具有明显的差别，因此判断单元220可以根据运动数据的变化趋势先判断出用户正在进行左手操作还是右手操作。
需要说明的是，移动终端也可以不通过运动数据的变化趋势来判断用户正在进行左手操作还是右手操作，比如，移动终端可以直接检测一段时间内采集到的运动数据是正值还是负值，通过正负值的区别来判断用户正在进行左手操作还是右手操作。
然后，移动终端根据左右手的判断结果将所述运动数据与对应的预设数据进行对比。若移动终端处于左手操作状态，则第一对比单元230对比左手操作状态下相应的预设数据；反之，若移动终端处于右手操作状态，则第二对比单元240对比右手操作状态下相应的预设数据，由此得到对比结果。在更多的实施中也可以不判断所述移动终端处于左手操作状态还是右手操作状态，直接将运动数据与预设的左右手操作状态下的预设数据进行对比，判断所述运动数据的变化趋势是否与左手或右手对应的预设数据的变化趋势相同，得到对比结果。
在本实施例中，第一获取模块100获取移动终端的运动数据；获取单元210获取所述运动数据的变化趋势；判断单元220根据所述变化趋势判 断所述移动终端处于左手操作状态还是右手操作状态；若所述移动终端处于左手操作状态，则第一对比单元230将所述运动数据与预设数据中左手数据进行对比；若所述移动终端处于右手操作状态，则第二对比单元240将所述运动数据与预设数据中右手数据进行对比；若所述运动数据与所述预设数据匹配，则控制模块300启动体感拨号功能。通过上述方式，由于用户在进行左手操作和右手操作时，加速度传感器采集到的加速度数据呈现相反的变化趋势，因此可以根据运动数据的变化趋势先判断出用户正在进行左手操作还是右手操作，再对比对应的操作状态下的运动数据和预设数据，从而有效地提高了对比的效率。
进一步地，参照图10，图10为图9中第一对比单元的细化功能模块示意图。所述第一对比单元230包括：
第一获取子单元231，配置为获取所述左手操作状态下的运动数据的最小值和第一终值；
第一对比子单元232，配置为将所述最小值和第一终值分别与预设负值和第一预设范围进行对比。
参照图11，图11为图9中第二对比单元的细化功能模块示意图。所述第二对比单元240包括：
第二获取子单元241，配置为获取所述右手操作状态下的运动数据的最大值和第二终值；
第二对比子单元242，配置为将所述最大值和第二终值分别与预设正值和第二预设范围进行对比；
参照图12，图12为8中控制模块的细化功能模块示意图。所述控制模块300包括：
第一控制单元310，配置为若所述最小值小于预设负值，且所述第一终值在第一预设范围之内，则启动体感拨号功能；
第二控制单元320，配置为若所述最大值大于预设正值，且所述第二终值在第二预设范围之内，则启动体感拨号功能。
在本实施例中，在判断单元220判断出移动终端处于左手操作状态还是右手操作状态之后，对比模块200再将相应操作状态下的运动数据和对应的预设数据进行进一步的对比分析。具体地，移动终端获取对应的操作状态下的运动数据的极值和终值，将所述极值和终值分别与对应的预设数据进行对比。
移动终端的运动数据由加速度传感器检测，由数据采集系统采集。加速度传感器可以检测在x、y、z三轴的加速度数据，经过大量的样本分析，对于拨打电话的动作，数据集呈现出明显的特征，可以与其它干扰动作形成明显的对比，此处仅以加速度计传感器x轴上的数据为例进行说明，对于其它轴的数据可以按照类似的方法提取，具体特征如下：
左手拨打电话：
刚开始的数据为一个正值，且变化平缓，经过短暂的时间后，会呈现一个小的波峰，之后数据快速衰减到一个最小值，该最小值一定小于某一负值，之后数据会有轻微的上升趋势，但由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值会有一定的取值范围。
右手拨打电话：
该过程呈现的数据变化与左手拨打电话的相反，刚开始的数据为一个负值，且变化平缓，经过短暂时间后，会出现一个小的波谷，之后数据快速上升到一个最大值，该最大值一定大于某一正值，之后数据会有轻微的下降趋势，但由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值也会存在一个取值范围。
对于其它可能导致误触的操作，此处仅以几例来说明其数据波形与正常拨打电话的区别：
手机从右手换到左手：
数据集刚开始的变化与左手拨打电话非常相似，但数据不会衰减到一个非常明显的负值，并且很多情况下，数据很长的拖尾，即在数据变化的末端，数据反复呈现出波峰和波谷。
将手机放到口袋中：
对于放左边口袋和右边的口袋，数据变化虽然不一样，但是都有明显的特征，即只在正值范围内变化或只在负值内变化。
右手挥舞手机靠近墙壁：
数据集刚开始的变化与右手拨打电话非常相似，但数据达到最大值后会有很长的拖尾而不会很快被截断。
根据以上描述，其他可能导致误触的动作与体感拨号动作的运动数据特征存在明显的不同，因此可以根据这些特征对运动数据进行定量分析。具体地，若移动终端处于左手操作状态，则第一获取子单元231可以在在数据的快速下降阶段获取所述运动数据的极小值，该极小值也是最小值，且一定小于某一负值；由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值一定在预设范围之内，第一对比子单元232将所述最小值和终值分别与预设负值和预设范围进行对比。若所述最小值小于预设负值，且所述终值在预设范围之内，则第一控制单元310可以认为所述运动数据和预设数据匹配，并启动体感拨号功能。反之，若移动终端处于右手操作状态，则第二获取子单元241可以在数据的快速上升阶段获取所述运动数据的极大值，该极大值也是最大值，且一定大于某一正值；由于数据采集系统的有效工作，数据会被很快截断到某一终值，该终值也一定在预设范围之内，第二对比子单元242将所述最大值和终值分别与预设正值和预设范围进行对比。若所述最大值大于预设正值，且所述终值在预设范围之内，则第二控制单元320可以认为所述运动数据和预设数据匹配，并 启动体感拨号功能。
在本实施例中，第一获取模块100获取移动终端的运动数据；获取单元210获取所述运动数据的变化趋势；判断单元220根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；第一获取子单元231获取所述左手操作状态下的运动数据的最小值和第一终值；第一对比子单元232将所述最小值和第一终值分别与预设负值和第一预设范围进行对比；若所述最小值小于预设负值，且所述第一终值在第一预设范围之内，则第一控制单元310启动体感拨号功能；第二获取子单元241获取所述右手操作状态下的运动数据的最大值和第二终值；第二对比子单元242将所述最大值和第二终值分别与预设正值和第二预设范围进行对比；若所述最大值大于预设正值，且所述第二终值在第二预设范围之内，则第二控制单元320启动体感拨号功能。由于用户在进行左右手操作时会有各种不同的动作，而每种动作所对应的运动数据不同，本实施例通过定量的分析运动数据是否与预设的体感拨号数据匹配，从而识别出体感拨号动作，能够有效降低体感拨号的误识别率，满足用户在各种场景下进行体感拨号的需求，提升用户体验。
进一步地，参照图13，图13为本发明体感拨号的控制装置第二实施例的功能模块示意图。所述装置还包括：
确定模块400，配置为根据所述运动数据确定所述移动终端在静止时的空间姿态；
所述获取单元210还配置为若所述移动终端在静止时的空间姿态为预设空间姿态，则获取所述运动数据的变化趋势。
在本实施例中，为进一步提高识别效率，在获取单元210获取所述运动数据的变化趋势之前，确定模块400可以先根据运动数据判断移动终端在静止时的空间姿态是否为预设的体感拨号的空间姿态，若是，则获取单 元210获取所述运动数据的变化趋势。
具体地，移动终端处于静止时会有各种不同的空间姿态，比如水平放置、竖直放置、倾斜放置等等。正常拨打电话时，移动终端处于静止状态且有一定的倾斜度，因此运动数据集的初始阶段变化缓慢且平稳，利用移动终端倾斜时在加速度敏感轴上的变化，即所谓的重力感应，可以感应倾斜角，该倾斜角应该在预设的范围之内，由此，通过对运动数据的简要分析就可以快速过滤掉一些不属于体感拨号的情况。
在本实施例中，第一获取模块100获取移动终端的运动数据；确定模块400根据所述运动数据确定所述移动终端在静止时的空间姿态；若所述移动终端在静止时的空间姿态为预设空间姿态，则获取单元210获取所述运动数据的变化趋势；判断单元220根据所述变化趋势判断所述移动终端处于左手操作状态还是右手操作状态；获取子单元231获取对应的所述操作状态下的所述运动数据的极值和终值；对比子单元232将所述极值和终值分别与对应的预设数据进行对比；若所述运动数据与所述预设数据匹配，则控制模块300启动体感拨号功能。由于静止时移动终端加速度传感器的数据只受重力影响，因此可以认为此时加速度传感器的数据就表示重力分量，因此经过简单的姿态转换可以得到移动终端此刻的姿态，并与正常拨打电话的姿态范围进行比较，快速过滤掉异常情况，从而提高算法的效率。
进一步地，参照图14，图14为本发明体感拨号的控制装置第三实施例的功能模块示意图。所述装置还包括：
建立模块500，配置为建立数据缓冲区，所述数据缓冲区用于存储当前预设连续时间内的运动数据；
所述第一获取模块100还配置为获取所述数据缓冲区中的运动数据。
在本实施例中，建立模块500可以建立一个数据缓冲区，用来存储当前预设连续时间内的运动数据，然后获取所述数据缓冲区中的运动数据。
作为一种实施方式，在加速度传感器实时获取移动终端的加速度数据的情况下，建立模块500始终保存的是用户最近连续操作的一段数据，以保证当采集的运动数据大于缓冲区大小时依然能有效工作。一般地，用户体感拨号动作的持续时间为1s到2s，建立模块500存储当前一段时间内的加速度数据。在检测到移动终端处于静止状态时，第一获取模块100逆序复制所述数据缓冲区的数据，并对数据进行分析。由于第一获取模块100在复制数据时采用的是逆序方式，即数据分析系统保存的数据是从耳边静止到远端开始运动的数据集，这种方式可以更高效的提取波形变化特征。
需要说明的是，数据缓冲区的大小可以根据拨号时间灵活设置，在复制数据缓冲区的运动数据时，也可以不采用逆序的方式，比如，可以采用正序的方式复制所述数据缓冲区中的运动数据，在进行数据分析时采用逆序分析，具体实施中可以根据实际需要进行灵活设置。
进一步地，所述装置还包括：
第二获取模块600，配置为通过距离传感器获取移动终端的距离数据；
判断模块700，配置为根据所述距离数据判断所述移动终端是否处于接近状态；
所述第一获取模块100还配置为若所述移动终端处于接近状态，则获取所述数据缓冲区中的运动数据。
在本实施例中，为进一步提高识别效率，在第一获取模块100获取数据缓冲区的运动数据之前，第二获取模块600可以通过距离传感器获取移动终端的距离数据，判断模块700再根据所述距离数据判断所述移动终端是否处于接近状态，若是，则执行步骤：获取所述数据缓冲区中的运动数据。
本实施例利用拨打电话需要靠近耳边这一特征，结合使用距离传感器，数据采集系统将只保留最能反应拨打电话的特征的运动数据集。移动终端 的运动过程可以包括运动接近和运动远离，这两种情况下数据采集系统都要采集运动数据；在移动终端处于静止状态时，第二获取模块600通过距离传感器获取移动终端的距离数据，从而判断模块700可以判断出移动终端是运动接近还是运动远离。在移动终端静止时，若移动终端处于远离状态，则直接清除刚刚采集到的运动数据；若移动终端处于接近状态，则第一获取模块100获取数据缓冲区中的运动数据，再对所述运动数据进行进一步分析。
参照图6，图6为本发明体感拨号的控制方法第四实施例的应用场景示意图。移动终端建立一个数据缓冲区，用来存储当前预设连续时间内的运动数据，然后数据分析系统获取所述数据缓冲区中的运动数据。具体实施方式如下：
首先，加速度传感器检测移动终端是否处于运动状态，只有在检测到移动终端处于运动状态时，数据采集系统才会收集数据，即将t时刻数据添加到数据缓冲区中。接着，距离传感器再检测移动终端是否处于接近状态，若移动终端不处于接近状态，则清理数据缓冲区中的数据。只有在移动终端处于接近状态时，才会启动数据分析系统对数据进行进一步分析。
参照图7，图7为图6中数据分析系统处理数据的具体流程示意图。以移动终端为手机进行说明。在手机处于静止且接近状态时，数据采集系统逆序复制缓冲区中的运动数据，并对数据进行平滑处理，通过读取初始数据分析手机静止时的状态，判断手机的空间姿态是否满足要求，若是，则再判断用户是左手还是右手拨打电话。若是左手拨号，则对数据波形依次进行平缓区间检测、波峰检测、快速衰减阶段检测、最小值检测和终止值检测，其中，波峰检测、最小值检测和终止值检测对应第二实施例中最小值和第一终值的处理过程；若是右手拨号，则对数据波形依次进行平缓区间检测、波谷检测、快速上升阶段检测、最大值检测和终止值检测，其中 波谷检测、最大值检测和终止值检测对应第二实施例中最大值和第二终值的处理过程。最后，返回识别结果。
在本实施例中，建立模块500存储当前预设连续时间内的运动数据；第二获取模块600通过距离传感器获取移动终端的距离数据；判断模块700根据所述距离数据判断所述移动终端是否处于接近状态；若是，则第一获取模块100获取所述数据缓冲区中的运动数据；对比模块200将所述运动数据与预设数据进行对比；若所述运动数据与所述预设数据匹配，则控制模块300启动体感拨号功能。本实施例通过建立数据缓冲区，配合使用距离传感器，只有在移动终端处于静止且接近状态时，才对数据缓冲区中的运动数据进行进一步分析，可以有效的减少分析的数据量，减少数据干扰，在很大程度上提升了体感拨号识别的效率。
在实际应用中，所述第一获取模块100、对比模块200、控制模块300、确定模块400、建立模块500、第二获取模块600以及判断模块700均可由中央处理单元(CPU，Central Processing Unit)、或数字信号处理(DSP，Digital Signal Processor)、或现场可编程门阵列(FPGA，Field Programmable Gate Array)等来实现；所述CPU、DSP、FPGA均可内置于控制装置中。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。

本发明实施例通过获取移动终端的运动数据；将所述运动数据与预设数据进行对比，其中，所述预设数据为体感拨号的操作特征数据；若所述运动数据与所述预设数据匹配，则启动体感拨号功能。通过上述方式，本发明实施例根据体感拨号动作的运动数据与其他可能触发体感拨号的动作 相比，具有明显特征的现象，通过加速度传感器获取移动终端的运动数据，再将所述运动数据与预设体感拨号的数据进行对比，从而识别出能够反映体感拨号动作特征的运动数据，并启动体感拨号功能，实现对体感拨号功能的有效控制。本发明实施例能够有效地降低体感拨号的误识别率，同时由于本发明实施例根据能够反映体感拨号动作特征的运动数据启动体感拨号功能，因此无需考虑应用场景，从而能够满足用户在各种场景下进行体感拨号的需求，提升了用户体验。
