本公开实施例提供一种防误触区域动态调整方法10，应用于移动终端，移动终端包括触摸屏和加速度传感器，移动终端为了防止用户的误触引起不必要的操作而设置有防误触区域，防误触区域一般设置于移动终端触摸屏的边缘，一般为靠近用户通过手握持的位置，尤其在曲面屏的移动终端中，曲面的触摸屏延伸至移动终端侧面，因此，触摸屏的侧部往往在锁屏或其他状态下设置为防误触区域，防误触区域内忽略触摸信号，即用户即使触碰触摸屏的防误触区域，也不会有任何响应。防误触区域是设备需要灵活地应对接收正常状态的用户操作和防止突然运动而导致的误触操作，移动终端可以是如手机等设备。为此，本公开实施例提供的防误触区域动态调整方法10，如图1所示，包括步骤S11-步骤S13：An embodiment of the present disclosure provides a
步骤S11：获取加速度传感器输出的加速度数据。Step S11: Acquire acceleration data output by the acceleration sensor.
加速度传感器是一种能够测量加速度的传感器，能感受加速度并转换成可用输出信号。通常由质量块、阻尼器、弹性元件、敏感元件和适调电路等部分组成。加速度传感器在加速过程中，通过对质量块所受惯性力的测量，利用牛顿第二定律获得加速度值。根据加速度传感器敏感元件的不同，常见的加速度传感器包括电容式、电感式、应变式、压阻式、压电式等。加速度传感器的原理是牛顿第二定律，即加速度定律，也就是力的平衡，A(加速度)＝F(惯性力)/M(质量)，多数加速度传感器是根据压电效应的原理来工作的。所谓的压电效应就是“对于不存在对称中心的异极晶体加在晶体上的外力除了使晶体发生形变以外，还将改变晶体的极化状态，在晶体内部建立电场，这种由于机械力作用使介质发生极化的现象称为正压电效应”。加速度传感器就是利用了其内部的由于加速度造成的晶体变形这个特性。由于这个变形会产生电压，只要计算出产生电压和所施加的加速度之间的关系，就可以将加速度转化成电压输出。An accelerometer is a sensor that measures acceleration, senses it and converts it into a usable output signal. It is usually composed of mass blocks, dampers, elastic elements, sensitive elements and adaptive circuits. During the acceleration process, the acceleration sensor obtains the acceleration value by using Newton's second law by measuring the inertial force on the mass block. According to the different sensitive components of the acceleration sensor, common acceleration sensors include capacitive, inductive, strain, piezoresistive, piezoelectric and so on. The principle of the acceleration sensor is Newton's second law, that is, the law of acceleration, that is, the balance of forces, A (acceleration) = F (inertial force) / M (mass). Most acceleration sensors work according to the principle of piezoelectric effect. The so-called piezoelectric effect is "for a heteropolar crystal without a center of symmetry, the external force applied to the crystal will not only deform the crystal, but also change the polarization state of the crystal and establish an electric field inside the crystal. The phenomenon of polarizing a medium is called the positive piezoelectric effect". The accelerometer takes advantage of its internal crystal deformation caused by acceleration. Since this deformation generates a voltage, the acceleration can be converted into a voltage output by simply calculating the relationship between the generated voltage and the applied acceleration.
加速度传感器可以感知移动终端的运动状况，其持续输出每一时刻该设备在不同方向上的加速度值，在一实施例中，获取的加速度数据可以移动终端在三个维度的分加速度，即x轴分加速度、y轴分加速度和z轴分加速度，其中x轴分加速度可以对应于移动终端宽度方向，y轴分加速度可以对应于移动终端长度方向，z轴分加速度可以对应于移动终端的厚度方向。加速度数据可以存储在内存缓冲区或其他外部存储器中，按照时间先后顺序以队列或堆栈等逻辑结构排列，移动终端可以根据需要读取其中的数据，通过判断其大小变化，确定运动状况。The acceleration sensor can sense the motion status of the mobile terminal, and it continuously outputs the acceleration values of the device in different directions at each moment. In one embodiment, the acquired acceleration data can be the sub-acceleration of the mobile terminal in three dimensions, that is, the x-axis. Component acceleration, y-axis component acceleration, and z-axis component acceleration, where the x-axis component acceleration may correspond to the width direction of the mobile terminal, the y-axis component acceleration may correspond to the length direction of the mobile terminal, and the z-axis component acceleration may correspond to the thickness direction of the mobile terminal . Acceleration data can be stored in a memory buffer or other external memory, arranged in logical structures such as queues or stacks in chronological order, and the mobile terminal can read the data as needed, and determine the motion status by judging its size change.
步骤S12：通过加速度数据判断移动终端当前是否出现突然的运动。Step S12: Determine whether the mobile terminal is currently experiencing a sudden movement by using the acceleration data.
当移动终端突然晃动或剧烈抖动时，例如在公交车中，车速突然改变如急停或加速，加速度传感器输出的加速度数据将发生较大幅度的改变。读取加速度传感器输出的加速度数据，并对前后时刻的数据进行比较，从而检测移动终端是否突然从静止或平缓运动变为高速运动。When the mobile terminal suddenly shakes or shakes violently, for example, in a bus, the speed of the vehicle changes suddenly, such as sudden stop or acceleration, the acceleration data output by the acceleration sensor will change significantly. Read the acceleration data output by the acceleration sensor, and compare the data at the previous and previous times, so as to detect whether the mobile terminal suddenly changes from static or gentle motion to high-speed motion.
步骤S13：若移动终端当前出现突然的运动，则增大位于触摸屏边缘的防误触区域的面积。Step S13 : if the mobile terminal currently moves suddenly, the area of the anti-mistouch area located at the edge of the touch screen is increased.
当前移动终端越来越多采用大屏幕尤其是曲面屏来提升用户的操作体验。曲面屏幕是一种采用柔性塑料的显示屏，主要通过OLED面板来实现。相比直面屏幕，曲面屏幕弹性更好，不易破碎。用于移动终端时，曲面屏幕整体的弯曲设计有利于握持，和手心弧度贴合得更好，减少单手操作时大拇指触摸屏幕的距离，有助于提升大尺寸屏幕下横向跨屏操作的体验。曲线可以让手机持有者拥有更好的信息私密性，比如坐在旁边的人无法看到设备屏幕上显示的内容。大屏幕尤其是曲面屏幕的应用，一方面扩展了移动终端显示内容的区域，另一方面也使得几乎整个设备正面和侧面均处于可引发触摸操作的区域，用户很容易产生误操作，通常避免这种问题的做法是设备会预先设置一个防误触区域，处于屏幕边缘用户手掌或手指长时间握持和接触的位置。Currently, more and more mobile terminals use large screens, especially curved screens, to improve the user's operating experience. A curved screen is a display that uses flexible plastic and is mainly implemented through an OLED panel. Compared with the straight screen, the curved screen has better elasticity and is not easy to break. When used in mobile terminals, the overall curved design of the curved screen is conducive to holding, and fits better with the curvature of the palm of the hand, reducing the distance of the thumb touching the screen when operating with one hand, and helping to improve horizontal cross-screen operation under large-size screens. experience. Curves allow phone owners to have better information privacy, such as people sitting next to them not being able to see what's displayed on the device's screen. The application of large screens, especially curved screens, on the one hand, expands the area where the mobile terminal can display content, and on the other hand, makes almost the entire front and side of the device in the area that can trigger touch operations. Users are prone to misoperations, and this is usually avoided. The solution to this problem is that the device pre-sets an anti-mistouch area at the edge of the screen where the user's palm or fingers hold and touch for a long time.
当移动终端突然晃动或剧烈抖动时，用户会不由自主地紧紧握住移动终端，手掌或手指将触摸到屏幕边缘或屏幕更中间的部分，这将导致误触而产生不必要的操作，影响用户体验，虽然固定设置的防误触区域可以防止一部分误触，但也导致正常情况下该区域无法接收操作，并且在突发情况下，用户的误触面积将会增大，固定的防误触区域无法灵活应对。检测到移动终端突然运动状态后，移动终端增大防误触区域，可以灵活地防止此时用户应激反应而导致的误触操作，从而提升用户体验。When the mobile terminal suddenly shakes or shakes violently, the user will involuntarily hold the mobile terminal tightly, and the palm or fingers will touch the edge of the screen or the more middle part of the screen, which will lead to false touches and cause unnecessary operations and affect the user. Experience, although the fixed anti-mistouch area can prevent some mistouches, it also causes the area to fail to receive operations under normal circumstances, and in emergencies, the user's mistouch area will increase, and the fixed mistouch prevention Regions cannot respond flexibly. After detecting a sudden motion state of the mobile terminal, the mobile terminal increases the accidental touch prevention area, which can flexibly prevent accidental touch operations caused by the user's stress response at this time, thereby improving user experience.
在一实施例中，步骤S12可以包括：若当前时刻任一维度的分加速度减去前一时刻相同维度的分加速度的差值大于第一阈值，或，若当前时刻总加速度减去前一时刻总加速度的差值大于第二阈值，则判定移动终端出现突然的运动；其中，总加速度为三个维度的分加速度的矢量和。In one embodiment, step S12 may include: if the difference between the component acceleration of any dimension at the current moment minus the component acceleration of the same dimension at the previous moment is greater than the first threshold, or, if the total acceleration at the current moment is subtracted from the previous moment If the difference between the total accelerations is greater than the second threshold, it is determined that the mobile terminal has a sudden movement; wherein, the total acceleration is the vector sum of the component accelerations in three dimensions.
本实施例中，加速度的突然变化程度通过前后时刻的差值来判断，当差值大于第一阈值时即可认为此时移动终端发生了突然的运动。这种情况不仅仅考虑移动终端从静止出现突然运动，通过对每个维度的分加速度进行检测，可以在运动方向的突然改变也会引起防误触区域面积增大。In this embodiment, the sudden change degree of the acceleration is judged by the difference between the previous and the next time, and when the difference is greater than the first threshold, it can be considered that the mobile terminal has a sudden movement at this time. In this case, it is not only considered that the mobile terminal suddenly moves from being stationary, but by detecting the sub-acceleration of each dimension, the sudden change of the moving direction can also cause the area of the anti-mistouch area to increase.
在一实施例中，步骤S12可以包括：若前一时刻任一维度的分加速度小于第三阈值且当前时刻相同维度的分加速度大于第四阈值，或，若前一时刻总加速度小于第五阈值且当前时刻总加速度大于第六阈值，则判定移动终端出现突然的运动；其中，总加速度为三个维度的分加速度的矢量和；第四阈值大于第三阈值，第六阈值大于第五阈值。In one embodiment, step S12 may include: if the component acceleration of any dimension at the previous moment is less than the third threshold and the component acceleration of the same dimension at the current moment is greater than the fourth threshold, or, if the total acceleration at the previous moment is less than the fifth threshold And the total acceleration at the current moment is greater than the sixth threshold, it is determined that the mobile terminal has a sudden movement; wherein, the total acceleration is the vector sum of the component accelerations in three dimensions; the fourth threshold is greater than the third threshold, and the sixth threshold is greater than the fifth threshold.
本实施例中，加速度从较低值到较高值的短时间变化被用以确定发生突然运动。这种情况更侧重考虑用户在平稳地正常使用到突然发生运动的状态。In this embodiment, a short time change in acceleration from a lower value to a higher value is used to determine the occurrence of a sudden movement. In this case, it is more important to consider the state of the user from smooth and normal use to sudden movement.
在一实施例中，步骤S13可以包括：将防误触区域向触摸屏中央方向扩大。In an embodiment, step S13 may include: expanding the anti-mistouch area toward the center of the touch screen.
本实施例中，改变防误触区域面积可以通过改变区域形状来实现，将防误触区域从靠近边缘的地方向屏幕中央方向扩大，从而覆盖更多部分，甚至整个屏幕，从而减少用户的紧握和擦划等动作引起误操作的几率或完全避免误操作发生。In this embodiment, changing the area of the anti-mistouch area can be realized by changing the shape of the area, and expanding the anti-mistouch area from the place close to the edge to the center of the screen, so as to cover more parts or even the entire screen, thereby reducing the tension of the user. The probability of misoperation caused by actions such as grasping and swiping or completely avoiding the occurrence of misoperation.
如图2所示，移动终端的触摸屏11的边缘设置有防误触区域111，用户在正常情况下的握持通常只会触摸到边缘很小的部分，而当突发情况发生时，例如碰撞、骤停或加速等，用户会不自主地紧握手机，也可能发生手指偏滑等情况，这些均会造成更大范围的触摸，从而引起误操作，比如点开某个应用或者摁下某些操作按钮，有时会导致移动终端错误地发送信息、确认订单或打开很多应用程序，严重影响用户的操作，导致用户烦恼。As shown in FIG. 2 , the edge of the
因此，如图3所示，通过上述实施例的方式，当检测到突发状况时，灵活地将防误触区域向触摸屏11中央方向扩大，扩大后的防误触区域112面积更大，此时用户因突发情况导致的握持面积增大或无意间触碰触摸屏11的情况下，通过防误触区域112面积的增大，可以避免误操作的发生。Therefore, as shown in FIG. 3 , when an emergency situation is detected, the false-touch prevention area is flexibly expanded toward the center of the
在一实施例中，如图4所示，防误触区域动态调整方法10在步骤S11之前，还可以包括：步骤S14：获取防误触区域的预设设置，其中，预设设置包括移动终端初始的设置或用户自定义的设置；防误触区域动态调整方法10还可以包括：步骤S15：若移动终端当前没有出现突然的运动，则根据预设设置，保持防误触区域。In one embodiment, as shown in FIG. 4 , before step S11 , the
本实施例中，触摸屏防误触区域的大小和形状可以在出厂时设置，用户也可以通过交互界面自定义设置相关参数，区域面积将根据用户需求被设置为对应的大小，动态调整区域面积是在误触区域的预设设置的基础上进行的。在用户正常使用或者从突然运动中恢复正常时，防误触区域保持初始水平，从而保证用户的正常使用。In this embodiment, the size and shape of the anti-mistouch area of the touch screen can be set at the factory, and the user can also customize the relevant parameters through the interactive interface.
