步骤S1021：根据获取的压力计算移动终端除屏幕以外的表面上所受的平均压力。
步骤S1022：将移动终端除屏幕以外的表面上所受压力与平均压力的差值大于设定的第一阈值的点作为按压点并统计按压点的数量。
可以理解，当移动终端的任意一个侧面或背面被放置于一个平面上的时候，该侧面或背面上的受力应该是比较均匀的，或者，当移动终端处于手持的状态时，该移动终端的表面受力应该是较为均匀的，而当用户有意对移动终端的表面进行按压时，在移动终端的表面上就会出现受力明显大于其他区域的按压点。利用这个特性，步骤S1011先求出移动终端除屏幕以外的表面上的压力平均值，而后步骤S1012就可根据预先设定的第一阈值判断移动终端除屏幕以外的表面上所具有的按压点的数量了。通过第一阈值的设定，可以控制本发明利用按压方式解锁时的灵敏度，当需要尽量防止误解锁时，可将第一阈值设得高一些。
在一个实施例中，步骤S103中，当按压点的数量不小于（大于或等于）最低限值时解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。用户在使用移动终端的过程中，移动终端可能遭受某些碰撞或挤压，这时，移动终端上可能存在一个受力明显高于周边的点，因此在本实施例中，为了防止频繁的误解锁（非用户本意的解锁）情况的出现，优选地，最低限值的取值不小于（大于或等于）2，显然，最低限值越大（即需要用户同时按压的点越多），就越不容易出现误解锁的情况，但是应该理解，最低限值的取值范围不是本发明的必要技术特征，即使最低限值取值为1，也并不影响本发明方法的实施。
在另一个实施例中，步骤S103包括：
S1031：判断按压点的数量是否满足预设的数量要求，如果是，则执行步骤S1032，否则保持移动终端的屏幕锁定状态。
S1032：判断用户输入的解锁口令与预置口令是否一致，如果是，则解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
其中，预置的数量要求与上文所说的一致，是一个以最低限值为基准的数量限制，当按压点的数量达到或超过这个最低限值时，认为按压点的数量满足了预置的数量要求。在该实施例中，除了将按压点的数量作为解除移动终端的屏幕锁定状态的依据，进一步地，还需要依据解锁口令决定是否对移动终端的屏幕进行解锁。通过这种方式进行解锁，可以有效保护使用该移动终端的用户的隐私。值得注意的是，本发明中所述的口令，既可以是文本，也可以是图形，或者是语音，本发明对此不加以限定。
在上述解除移动终端屏幕锁定的方法中，如果该移动终端上只有某些区域装有压力传感器，相应的，可以把实施过程中移动终端除屏幕以外的表面限定为压力传感器所覆盖的区域，由于解锁过程并无实质区别，在此不再赘述。
请参考图4，图4为本发明中解除移动终端屏幕锁定的方法的实施例二的流程示意图。如图4所示，该实施例包括：
S201：移动终端在处于锁定状态的屏幕上指示至少两个按压点，其中各按压点位于移动终端的任意侧面或背面。
S202：获取各按压点处所受的压力。
S203：根据各按压点处所受的压力决定是否解除移动终端的屏幕锁定状态。
请参考图5，图5为本发明中移动终端的屏幕的实施例的示意图。如图5所示，以箭头和文字（请按压两侧以解锁设备）的形式向用户指示了两个位于手机侧面的按压点（表现为一个区域），用户只有在该按压点所在的区域进行按压才能解锁移动终端。
优选地，对较小的移动终端（如手机），可以在移动终端的两个侧面（上下左右中的任意两个）各指示一个按压点供用户按压解锁，这样，用户单手手持设备同时按压两侧就能完成解锁动作，提高了解锁的效率，对较大的移动终端（如平板电脑），可以在移动终端的一个侧面和背面各指示一个按压点供用户按压解锁。
移动终端在所指示的按压点所在区域装有压力传感器，因此，当用户在指示的按压点对设备进行按压时，本发明的方法将在步骤S202中获取到各按压点所受的压力，并在步骤S203中根据获取的压力判断是否对设备进行解锁。
在一个实施例中，步骤S203中，当各按压点处所受的压力均大于设定的第二阈值时，解除移动终端的屏幕锁定状态，否则保持所述移动终端的屏幕锁定状态。
移动终端在用户的使用过程中，可能发生碰撞或挤压，通过第二阈值，可以保证各按压点处的受力中的最小值都足够大时才会对设备解锁，显然，如果不是用户主动在每个按压点处施力，上述对移动终端的偶然碰撞或挤压很难满足这样的解锁条件。
在另一个实施例中，步骤S203中，还可以当各按压点处所受压力的均值大于设定的第三阈值且各按压点处所受压力的标准差小于设定的第四阈值时，解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
第三阈值与第四阈值，可以保证设备在各按压点处的受力较为均匀且每个按压点处的受力都足够大时才对设备解锁，通过前面的分析可以看出，这也能够很好地避免移动终端在使用过程中因偶然的碰撞和挤压造成的误解锁状况的出现。
在一个实施例中，步骤S203包括：
步骤S2031：判断各按压点处所受的压力是否满足预设要求，如果是，则执行步骤S2032，否则保持移动终端的屏幕锁定状态。
步骤S2032：判断用户输入的解锁口令与预置口令是否一致，如果是，则解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
其中步骤S2031中的预设要求可以是上述与第二阈值相关的限制条件，或者是上述与第三阈值及第四阈值相关的限制条件。例如：当获取到各按压点所受压力均大于第二阈值时，提示用户输入解锁口令，在用户输入解锁口令后，将该解锁口令与预置口令进行匹配判断，如果匹配则解除移动终端的屏幕锁定状态。
在上述解除移动终端屏幕锁定的方法的实施例一与实施例二中，在压力传感器获取到移动终端的表面（或按压点处）的压力后，也可以先比较获取到的压力中的最大值与预先设定的临界值之间的关系后再决定是否触发后续的处理流程，当获取到的压力当中的最大值超过临界值时才触发后续处理流程执行。因为移动终端表面完全无压力的情况很少存在，上述方式可以减少触发处理器进行算术运算和逻辑运算的次数。
请参考图6，图6为本发明中移动终端的实施例一的结构示意图。如图1所示，该移动终端包括：压力感知模块301、判断处理模块302及解锁控制模块303。
其中，压力感知模块301，用于在移动终端处于屏幕锁定的状态下获取来自移动终端除屏幕以外的表面上受到的压力。
在本发明的移动终端的上下左右四个侧面及背面可以安装压力传感器。从而使移动终端的四个侧面及背面构成按压区。这些压力传感器是压力感知模块301的硬件基础。
判断处理模块302，用于根据获取的压力确定移动终端除屏幕以外的表面上按压点的数量。
具体地，判断处理模块302包括：
计算单元3021，用于根据压力感知模块301获取的压力计算移动终端除屏幕以外的表面上所受的平均压力。
确定单元3022，用于将移动终端除屏幕以外的表面上所受压力与平均压力的差值大于设定的第一阈值的点作为按压点并统计按压点的数量。
可以理解，当移动终端的任意一个侧面或背面被放置于一个平面上的时候，该侧面或背面上的受力应该是比较均匀的，或者，当移动终端处于手持的状态时，该移动终端的表面受力应该是较为均匀的，而当用户有意对移动终端的表面进行按压时，在移动终端的表面上就会出现受力明显大于其他区域的按压点。利用这个特性，判断处理单元302的上述实施方式，可以有效控制移动终端利用按压方式解锁时的灵敏度，当需要尽量防止误解锁时，可将第一阈值设得高一些。
解锁控制模块303，用于根据按压点的数量决定是否解除移动终端的屏幕锁定状态。
具体地，在一个实施例中，当按压点的数量不小于（大于或等于）最低限值时，解锁控制模块303解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
容易理解，用户在使用移动终端的过程中，移动终端可能遭受某些碰撞或挤压，这时，移动终端可能会存在一个受力明显高于周边的点，因此在本实施例中，为了防止频繁的误解锁（非用户本意的解锁）情况的出现，最低限值的取值应该不小于（大于或等于）2，显然，最低限值越大（即需要用户同时按压的点越多），就越不容易出现误解锁的情况。
请参考图7，图7为本发明中解锁控制模块的一个实施例的结构示意框图。如图7所示，解锁控制模块303包括数量判断单元3031及口令判断单元3032。
其中，数量判断单元3031，用于判断按压点的数量是否满足预设的数量要求，如果是，则触发口令判断单元3032运行，否则保持移动终端的屏幕锁定状态。
口令判断单元3032，用于判断用户输入的解锁口令与预设口令是否一致，如果是，则解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
请参考图8，图8为本发明中移动终端的实施例二的结构示意框图。如图8所示，该移动终端包括：指示模块401、压力感知模块402及解锁控制模块403。
其中指示模块401，用于在移动终端处于锁定状态的屏幕上指示至少两个按压点，其中各按压点位于移动终端的任意侧面或背面。
压力感知模块402，用于获取各按压点处所受的压力。
解锁控制模块403，用于根据各按压点处所受的压力决定是否解除移动终端的屏幕锁定状态。在一个实施例中，解锁控制模块403当各按压点处所受的压力均大于设定的第二阈值时，解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态，或者，解锁控制模块403当各按压点处所受压力的均值大于设定的第三阈值且各按压点处所受压力的标准差小于设定的第四阈值时，解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
在另一个实施例中，解锁控制模块403包括一个压力判断单元（图中未示出）和口令判断单元（图中未示出），其中压力判断单元用于判断各按压点处所受的压力是否满足预设要求，如果是，则触发口令判断单元运行，否则保持移动终端的屏幕锁定状态。口令判断单元，用于判断用户输入的解锁口令与预置口令是否一致，如果是，则解除移动终端的屏幕锁定状态，否则保持移动终端的屏幕锁定状态。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
