【具体实施方式】
本发明提供一种基于终端设备的音量调节方法及系统，为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
本发明中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明，其本身并没有特定的意义。因此，模块”、“部件”或“单元”可以混合地使用。
终端设备可以以各种形式来实施。例如，本发明中描述的终端可以包括诸 如移动电话、智能电话、笔记本电脑、数字广播接收器、PDA(个人数字助理)、PAD(平板电脑)、PMP(便携式多媒体播放器)、导航装置等等的移动终端以及诸如数字TV、台式计算机等等的固定终端。然而，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
下面结合附图，通过对实施例的描述，对发明内容作进一步说明。
请参照图1，图1为本发明提供的基于终端设备的音量调节方法的较佳实施例的流程图。所述方法包括：
S100、当终端设备处于通话状态时，实时监听触摸屏被触发所产生的滑屏操作，并判断所述滑屏操作是否为有效滑屏操作。
具体地，所述终端设备处于通话状态指的是终端设备通过通话功能与其他具有通话功能的终端设备进行通话。在终端设备处于通话状态时，实时监听触摸屏被触发所产生的滑屏操作。所述滑屏操作为用户触摸触摸屏所产生的。
由于终端设备处于通话状态时普遍处于黑屏状态，对于触摸屏被触摸而产生的滑屏操作不进行响应，从而当监听到所述滑屏操作时，还应该判断所述滑屏操作是否为有效操作。所述有效操作为触发所述终端设备进行后续调节的触发指令，也就是说，只有当所述滑屏操作为有效滑屏操作时，所述终端设备才会接收所述滑屏操作，并根据所述滑屏操作对音量进行相应调节。所述判断滑屏操作是否为有效滑屏操作的具体过程可以为：
S101、当终端设备处于通话状态时，实时监听触摸屏被触发所产生的滑屏操作。
具体地，所述实时监听触摸平被触发所述产生的滑屏操作指的是实时监听用户在触摸屏上滑动而产生的滑屏操作。也就是说，所述滑屏操作为连续触摸触摸屏而产生的触摸操作。
S102、当监听到滑屏操作时，获取所述滑屏操作的滑动轨迹。
具体地，当监听到滑屏操作时，获取所述滑屏操作在触摸屏上形成的滑动 轨迹，所述滑动轨迹为触摸触摸屏形成的触摸轨迹。获取滑动轨迹可以通过获取滑屏所产生的触摸点，根据所述触摸点计算所述滑屏操作对应的滑动轨迹。其具体可以通过如下过程实现：
S1021、当监听到滑屏操作时，获取所述滑屏操作产生的触摸点坐标。
具体，当监听到滑屏操作时，实时获取所述滑屏操作所产生的触摸点的坐标。在实际应用中，当监听到滑屏操作时，首先获取起始点坐标以及第二点坐标，并存储所述起点坐标以及第二点坐标，当获取第三点坐标时，采用第三点坐标更新已存储第二点坐标。也就是说，滑屏操作的任意时刻，仅需存储起始点坐标以及当前点坐标，这样可以减少终端设备对应触摸点的存储，降低对终端设备存储空间的使用，同时还可以降低能耗，提高终端设备的使用寿命。
S1022、根据所述触摸点坐标计算滑屏操作对应的滑动轨迹，其中，所述滑动轨迹为有起始点与当前点构成的线段。
具体地，根据所述触摸点坐标计算滑屏操作对应的滑动轨迹指的是根据存储的起始点的坐标和当前点的坐标计算所述滑动轨迹，也就是说，所述滑动轨迹为起始点和当前点构成的线段。这里设起始点坐标为(x1，y1)，当前点坐标为(x2，y2)，那么当前有效滑动轨迹为：
Figure PCTCN2017094126-appb-000001
S103、将所述滑动轨迹与预设阈值进行比较，当所述滑动轨迹大于等于所述预设阈值时，判定所述滑屏操作为有效滑屏操作。
具体地，所述将滑动轨迹与预设阈值进行比较指的是将所述起始点坐标与当前点坐标的连线L与预设阈值进行比较，用以判断所述滑动轨迹对应的滑屏操作是否为有效操作，这样可以避免由于用户误碰触摸屏而产生的误操作。
所述预设阈值为预先设置用于判断所述滑屏操作是否为有效滑屏操作的门限值，当滑动轨迹大于等于所述预设阈值时，判定所述滑动操作为有效滑动操作。当滑动轨迹小于预设阈值时，判断所述滑动操作为无效滑动操作，则不做任何响应。所述预设阈值可以是系统默认设置的，也可是用户根据自身需要通 过终端设备的设置界面自行设置的，如，2.5cm等。
进一步，根据滑动轨迹的计算方式中可以看出，所述滑屏操作所产生的触摸点的不同，所述滑动轨迹的方向以及长度也会发生相应的变化，并且所述长度也可能会减小。因此，在本实施例中，所述判断滑动操作是否有效滑动操作中，当滑动轨迹大于等于预设阈值时，则判断滑动操作为有效操作。这里滑动轨迹大于等于预设阈值指的是在滑屏操作过程中存储滑动轨迹大于等于预设阈值的滑动轨迹，则说明所述滑动操作为有效滑动操作。这样可以减少滑动轨迹的精确性要求，方便用户使用。
S200、当所述滑屏操作为有效滑屏操作时，分别获取所述滑动轨迹在水平方向和竖直方向的投影。
具体地，当所述滑屏操作为有效滑屏操作时，解释所述滑屏操作并对所述滑屏操作进行后续操作。所述后续操作为将所述滑动轨迹在水平方向和竖直方向做投影，并获取所述投影的方向与长度，根据方向与长度对音量进行相应调节。其具体可以为：
S201、当所述滑屏操作为有效滑屏操作时，将所述滑动轨迹分别向水平方向和竖直方向做投影；
S202、根据滑动轨迹计算水平投影和竖直投影的方向和长度。
所述将所述滑动轨迹分别想水平方向和竖直方向做投影指的是将起始点和当前点构成的线段向水平方向和竖直方向做投影，获取所述线段在水平方向上的投影的方向和长度以及所述线段在竖直方向上的投影的方向和长度。这里，所述方向指的投影所得线段的方向，水平方向上的投影的方向即为判断所述投影所得线段的方向为向左还是向右，所述竖直方向上的投影的方向即为判断所述投影所得线段的方向为向上还是向下。所述长度指的是所述投影所得的线段的长度。
在获取到滑动轨迹的水平投影和竖直投影的方向和长度后，根据所述水平投影和竖直投影的方向和长度对音量进行相应调节。所述音量包括听筒音量和 麦克风音量。
S300、根据预设所述投影与音量的对应关系获取所述投影对应的音量调节方式，并根据所述音量调节方式对音量进行相应调节。
具体地，所述根据预设所述投影与音量的对应关系获取所述投影对应的音量调节方式指的是根据预设所述投影方向与音量的对应关系获取所述投影对应的音量调节方式。
示例性的，所述根据预设所述投影与音量的对应关系获取所述投影对应的音量调节方式具体可以为：
S301、将所述水平投影的长度与竖直投影的长度做差，并根据所述差的正负确定所述滑动轨迹的有效投影，其中，所述有效投影为水平投影或竖直投影。
具体地，将获取的水平投影的长度与竖直投影的长度做差指的是将所滑动轨迹的水平分量长度与竖直分量长度做差，根据所述差来判断水平投影为有效投影还是竖直投影为有效投影。当所述差为正数时，说明所述水平分量为有效投影，当差为负数时，说明所述竖直分量为有效投影。
进一步，所述水平投影的长度与竖直投影的长度做差可以通过如下过程实现读取存储的起始点坐标和当前点坐标，根据所述起始点坐标和当前点坐标获取滑动轨迹线段，将所述线段在水平和垂直方向上的投影变化量Δx和Δy，其中，所述Δx＝x2-x1，Δy＝y2-y1。对Δx和Δy取绝对值后进行做差，得到水平投影的长度与竖直投影的进行比较，若|Δx|＞|Δy|，认为是水平左右滑；若|Δy|≥|Δx|，认为是垂直上下滑。
进一步，根据比较结果选取对应方向的投影变化量进行正负属性判断，并根据正负属性判断结果并根据所述判断结果确定音量调节方式。例如，提取Δx与0比较，若Δx＞0，认为是水平右滑；Δx＜0，认为是水平左滑；提取Δy与0比较，若Δy＞0，认为是垂直上滑；Δy＜0，认为是垂直下滑。
S302、根据投影与音量调节的对应关系确定所述有效投影方向对应的音量调节方式，并根据所述音量调节方式对音量进行相应调节。
具体地，当确定所述有效投影的方向后，根据投影与音量调节的对应关系确定所述有效投影方向对应的音量调节方式，并根据所述音量调节方式对音量进行相应调节。
示例性的，所述根据投影与音量调节方式的对应关系可以为：
当投影为水平向左时，减小麦克音量；
当投影为水平向右时，加大麦克音量；
当投影为垂直向下时，减小听筒音量；
当投影为垂直向上时，加大听筒音量。
相应的，所述投影为滑屏操作所产生的滑动轨迹向水平方向或竖直方向的投影，从而根据投影与音量调节方式的对应关系可以得出滑屏操作与音量调节方式的对应关系，其具体可以为：
当水平向左滑动时，减小麦克音量；
当水平向右滑动时，加大麦克音量；
当垂直向下滑动时，减小听筒音量；
当垂直向上滑动时，加大听筒音量。
从而在实际应用中，可以通过控制滑屏操作的方向对音量进行相应的调节，如：
若用户当前滑屏是想减小麦克音量，则用户沿水平方向左滑，则|Δx|＞|Δy|，且Δx＜0；那么根据滑动轨迹的有效投影方向可以判断是减小麦克音量的需求，故执行减小麦克音量的操作。
若用户当前滑屏是想加大麦克音量，则用户沿水平方向右滑，则|Δx|＞|Δy|，且Δx＞0；那么根据滑动轨迹的有效投影方向可以判断是加大麦克音量的需求，故执行加大麦克音量的操作。
若用户当前滑屏是想减小听筒音量，则用户沿垂直方向下滑，则|Δy|≥|Δx|，且Δy＜0；那么根据滑动轨迹的有效投影方向可以判断是减小听筒音量的需求，故执行减小听筒音量的操作。
若用户当前滑屏是想加大听筒音量，则用户沿垂直方向上滑，则|Δy|≥|Δx|，且Δy＞0；那么根据滑动轨迹的有效投影方向可以判断是加大听筒音量的需求，故执行加大听筒音量的操作。
