一种智能终端的屏幕控制方法及屏幕控制系统 技术领域
本发明涉及智能终端领域，尤其涉及一种智能终端的屏幕控制方法及屏幕控制系统。
背景技术
随着电子技术的快速发展，现代人们的生活也越来越智能化。自首款智能终端问世以来，智能终端的制造商就在不断的改进产品设计，越来越多无法想象到的功能来到我们身边，随着智能终端功能的丰富以及移动互联网的快速发展，智能终端已然取代了我们身边很多常用的电子设备，改变着我们的生活方式以及周边的行业。
近年来，触摸技术在智能终端市场得到了广泛的应用，触摸屏手机更成为各大厂商竞争的焦点。触摸屏手机最大的特点在于它超大的屏幕，可以给使用者带来视觉的享受，无论从文字还是图像方面都体现出大屏幕的优势。一方面，为了节约电池电源，维持智能终端的续航时间，另一方面，为了避免用户在使用过程中挤压、碰撞而造成的误操作，智能终端通常都对屏幕采取了锁屏的策略，即智能终端在设定长度的时间内没有任何的用户输入操作，就会自动将屏幕锁定，无法进行除解锁外的任何其他操作，例如，用户在一段时间内不操作智能终端，则智能终端的屏幕收到程序的控制而熄屏，此外，也可以由用户自行锁定屏幕，使智能终端处于不能响应用户除解锁以外的其他输入的状态，例如，用户点击电源键(power键)可锁定屏幕，在需要使用智能终端时，重新点击电源键(power键)可唤醒点亮屏幕，继而验证通过锁屏界面，进入正常使用智能终端的使用界面。
对处于锁屏状态下的智能终端，为使其能够响应用户的任意输入，首先需要解除智能终端的屏幕锁定状态。在现有技术中，智能终端的解锁方法主要有以下几种：滑动智能终端屏幕上的解锁块对智能终端进行解锁，或者，在智能终端的屏幕上执行某个特定的手势进行解锁，或者通过密码、PIN码、语音、虹膜、人脸识别等方式进行解锁。然而，对于智能终端的锁屏方法，却仅仅只有点击电源键进行锁屏的方式。上述锁屏方法极为单一，使用普遍，无法满足用户的个性化需求。
因此，本发明提供了一种智能终端的屏幕控制方法及屏幕控制系统，屏幕控制方法包括以下步骤：于所述智能终端内设定一预设锁屏手势；当所述智能终端处于屏幕解锁状态时，获取所述智能终端屏幕接收的当前锁屏手势；判断所述当前锁屏手势与所述预设锁屏手势是否一致；当所述当前锁屏手势与所述预设锁屏手势一致时，所述智能终端锁屏并熄屏；当所述当前锁屏手势与所述预设锁屏手势不一致时，维持所述智能终端的屏幕解锁状态。本发明提供的智能终端的屏幕控制方法及屏幕控制系统，根据用户设定的手势进行锁屏操作，满足用户个性化定义锁屏方式的需求。

参考图1，本发明的智能终端的屏幕控制方法，包括以下步骤：
S100：于所述智能终端内设定一预设锁屏手势；
S200：当所述智能终端处于屏幕解锁状态时，获取所述智能终端屏幕接收的当前锁屏手势；
S300：判断所述当前锁屏手势与所述预设锁屏手势是否一致；
S400：当所述当前锁屏手势与所述预设锁屏手势一致时，所述智能终端锁屏并熄屏；当所述当前锁屏手势与所述预设锁屏手势不一致时，维持所述智能终端的屏幕解锁状态。
本发明提供的屏幕控制方法，可以应用于智能手机的屏幕上，通常是智能手机的正面屏幕，对于无边框及超大屏占比设计的智能手机，也可以应用于智能手机的左右两侧面、前后两侧面甚至背面屏幕。
本发明提供的屏幕控制方法，可以应用于智能手机处于亮屏且屏幕解锁状态时，获取智能手机的锁屏手势进行逻辑判断是否进行锁屏及熄屏操作，也可以应用于智能手机处于亮屏且屏幕锁定状态时，获取智能手机的锁屏手势进行逻辑判断是否进行熄屏操作。
-S100：于所述智能终端内设定一预设锁屏手势；
首先，在智能终端内预设一锁屏手势，作为逻辑判断的条件。该锁屏手势可以根据用户的需要自由设定，例如滑动手势、按压手势等。可以理解的是，该预设的锁屏手势可以是与用户触摸屏幕有关的所有手势，并不限于上述几种。
以按压手势为例，设置的按压手势可以包括但不限于按压点的数量、按压点的位置、按压点位置组成的图形、按压点的压力大小、按压点的压力时间等的一种或者是其中多种的任意组合。例如，将预设的按压手势设置为按压点数量与按压点位置组成的图形的组合，则用户需要事先在智能手机内设定预设的按压点数量与按压点位置组成的图形的 组合，例如，设置判断条件一为按压点数量为三个，设置判断条件二为按压点位置组成的图形为三角形。之后，用户在智能手机处于屏幕解锁状态时，按压智能手机的屏幕，压力传感器获取用户按压智能手机屏幕的按压手势，进一步获取按压手势的当前按压点数量、当前按压点位置组成的图形，进而，判断当前按压点数量是否与判断条件一一致，即检测到的当前按压点数量是否为三个，以及，判断当前按压点位置组成的图形是否满足判断条件二，即检测到的当前按压点位置组成的图形是否为三角形，只有当判断条件一、二均一致时，智能手机锁屏，否则，智能手机仍然维持屏幕解锁状态。
当用户设定的预设按压手势需要获取多个按压点时，对多个按压点的获取可以是同时的，也可以是不同时的。即，用户可以使用单手同时将三个手指按压智能手机的屏幕，如用户使用右手拇指、食指、中指同时按压屏幕，此时压力传感器同时获取这三个手指的按压点并进行逻辑判断。当然，用户也可以使用单手依次按压智能手机的屏幕，如用户使用食指依次按压智能手机屏幕三次，此时压力传感器依次获取这三个按压点并进行逻辑判断，在这种情况下，只要连续的三个按压点符合逻辑判断的条件即可解锁屏幕，例如，用户设置按压点位置组成的图形为三角形作为预设按压手势，则用户使用食指依次按压智能手机屏幕五次，其中，第三、四、五次按压点位置组成的图形为三角形，即可锁定屏幕。
此外，还可以设定智能终端用于获取锁屏手势的识别区域，例如，设定智能终端的整个屏幕作为识别区域，用户在智能终端的整个屏幕的任意位置进行锁屏手势的操作时，均可被识别；又如，设定智能终端的下半个屏幕作为识别区域，用户在智能终端的下半屏幕的任意位置进行锁屏手势操作时，可以被识别；又如，用户自由选取智能终端屏幕的某一区域并设定该区域作为识别区域，用户在智能终端屏幕的选定区域内进行锁屏手势操作时，可以被识别。在此基础上，还可以在智能终端的识别区域上设置基准点，例如，设置3×3均匀排列的9个基准点，用户连接相应基准点的锁屏手势可以被识别。
-S200：当所述智能终端处于屏幕解锁状态时，获取所述智能终端屏幕接收的当前锁屏手势；
如上所述，在智能终端处于屏幕解锁状态时，获取所述智能终端屏幕接收的当前锁屏手势，进行锁屏及熄屏操作；也可以在智能终端处于亮屏但屏幕锁定状态时，获取所述智能终端屏幕接收的当前锁屏手势，进行熄屏操作。
具体地，以设定锁屏手势为按压手势为例：
获取智能手机屏幕的锁屏手势的方法可以是，当本发明应用于智能手机的正面屏幕上时，在本发明的智能手机的正面安装压力传感器，从而使智能手机的正面构成识别区 域，当本发明应用于智能手机的正面屏幕以外的屏幕时，在本发明的智能手机的上下左右四个侧面及背面安装压力传感器，从而使智能手机的四个侧面及背面屏幕构成识别区域。
基于这些压力传感器，即可利用这些传感器获取来自智能手机屏幕的表面上受到的按压压力。本发明不限定压力传感器在智能手机屏幕表面上所处的具体位置以及压力传感器的个数。特别地，可以以本领域技术人员能够实现的方式在智能手机屏幕表面上的适当位置安装适当个数的压力传感器，以实现在智能手机屏幕表面上的任意位置均可感知压力，或者实现在智能手机屏幕的部分位置的表面上的任意位置均可感知压力。例如，将本发明应用于智能手机的屏幕上，基于智能手机厚度、体积、经济效益或者用户使用习惯的考虑，在本发明的智能手机的正面下半部分安装压力传感器，从而使智能手机的正面下半部分构成识别区域，用户需要在识别区域内按压智能手机屏幕，才可获取当前锁屏手势。以下，将本发明应用于智能手机的屏幕上，在智能手机的屏幕所对对应的部分下设置压力传感器，识别区域设置为智能手机屏幕的正面部分，对本发明进行进一步说明。
参考图2，在一优选实施例中，S200：当所述智能终端处于屏幕解锁状态时，获取所述智能终端屏幕接收的当前锁屏手势的步骤包括：
判断所述智能终端的当前页面是否为主菜单页面；
当所述智能终端的当前页面为主菜单页面时，获取所述智能终端屏幕接收的当前锁屏手势。
在一实施例中，本发明提供的屏幕控制方法，只有当用户在菜单页面上输入锁屏手势时，才能进行锁屏操作。具体地，在获取屏幕接收的当前锁屏手势之前，首先检测智能手机的当前页面是否为主菜单页面，当所述智能终端的当前页面为主菜单页面时，获取所述智能终端屏幕接收的当前锁屏手势。
又如，本发明提供的屏幕控制方法，只有当用户在某些应用程序之外的页面上输入锁屏手势时，才能进行锁屏操作。此时，用户可以在智能手机内预先设定应用白名单，当检测到智能手机白名单内的应用程序在前台运行时，用户即使输入锁屏手势，也不能进行锁屏操作。
-S300：判断所述当前锁屏手势与所述预设锁屏手势是否一致；
-S400：当所述当前锁屏手势与所述预设锁屏手势一致时，所述智能终端锁屏并熄屏；当所述当前锁屏手势与所述预设锁屏手势不一致时，维持所述智能终端的屏幕解锁状态。
参考图3，在一优选实施例中，S300：判断所述当前锁屏手势与所述预设锁屏手势 是否一致的步骤包括：
于所述智能终端内设定一压力阈值；
检测所述当前锁屏手势按压所述屏幕的压力值；
判断所述当前锁屏手势按压所述屏幕的压力值与所述压力阈值；
当所述当前锁屏手势按压所述屏幕的压力值超过所述压力阈值时，判断所述当前锁屏手势与所述预设锁屏手势是否一致。
参考图4，进一步地，当所述当前锁屏手势按压所述屏幕的压力值超过所述压力阈值时，判断所述当前锁屏手势与所述预设锁屏手势是否一致的步骤包括：
于所述智能终端内设定一第一时间阈值；
检测所述当前锁屏手势按压所述屏幕的压力值超过所述压力阈值的第一时间值；
判断所述当前锁屏手势按压所述屏幕的压力值超过所述压力阈值的第一时间值与所述第一时间阈值；
当所述当前锁屏手势按压所述屏幕的压力值超过所述压力阈值的第一时间值超过所述第一时间阈值时，判断所述当前锁屏手势与所述预设锁屏手势是否一致。
以设定的锁屏手势为按压手势为例，将按压手势设为按压点的数量。但在具体操作时，并非将智能手机屏幕上检测到的所有受到按压压力的触点均可作为按压点。因此，可以预先设定一个压力阈值，获取智能手机屏幕上的按压手势，从而获取该按压手势的当前按压压力，只有当前按压压力超过压力阈值时，才将智能手机屏幕上接收有当前按压压力的触点作为一个按压点进行累计。
可以理解的是，当智能手机的正面被放置于一个平面上的时候，该正面上的受力应该是比较均匀的，或者，当智能手机处于手持的状态时，该智能手机的表面受力应该是较为均匀的，而当用户有意对智能手机的正面进行按压时，在智能手机的正面上就会出现受力明显大于其他区域的按压点。因此，可以利用这个特性，首先设定一压力差阈值，然后获取智能手机屏幕上的按压手势，从而获取该按压手势的当前按压压力，计算出智能手机屏幕上的压力平均值，然后，根据预先压力差阈值判断智能手机屏幕上所具有的按压点的数量，即，将智能手机屏幕上所受压力与压力平均值的差值大于设定的压力差阈值的点作为按压点并统计按压点的数量。通过压力差阈值的设定，可以控制本发明利用按压方式锁屏时的灵敏度，当需要尽量防止误锁屏时，可将压力差阈值设得高一些。
进一步地，预先设定一时间阈值，获取智能手机屏幕上的按压手势，从而获取按压手势的压当前按压压力，以及获取当前按压压力超过压力阈值的累计时间，只有当前按压压力超过压力阈值的累计时间超过时间阈值时，才将智能手机屏幕上接收有当前按压 压力的触点作为一个按压点进行累计。
参考图5，在一优选实施例中，S300：判断所述当前锁屏手势与所述预设锁屏手势是否一致的步骤包括：
于所述智能终端内设定一第二时间阈值；
检测所述当前锁屏手势按压所述屏幕的第二时间值；
判断所述当前锁屏手势按压所述屏幕的第二时间值与所述第二时间阈值；
当所述当前锁屏手势按压所述屏幕的第二时间值超过所述第二时间阈值时，判断所述当前锁屏手势与所述预设锁屏手势是否一致。
同样地，可以预先设定一时间阈值，获取智能手机屏幕上的按压手势，从而获取按压手势按压屏幕的累计时间，只有累计时间超过时间阈值时，才将智能手机屏幕上接收有按压压力的触点作为一个按压点进行累计。
