Furthermore, the mobile phone can determine whether the mobile phone satisfies the set adjustment conditions by combining the mobile phone's motion posture, ambient light intensity, mobile phone call status, and mobile phone screen status. If the adjustment condition is satisfied, the mobile phone can dynamically adjust the proximity light threshold of the proximity light sensor. For example, when the risk of false touch is relatively large, the mobile phone can use the near-light threshold with a small value to determine whether there is an obstruction approaching the mobile phone.
  • the proximity light threshold determines whether an obstruction is close to the phone. If it is determined that an obstruction is close to the mobile phone, the mobile phone may start an anti-mistouch algorithm to activate the anti-mistouch function of the mobile phone screen. Of course, if the mobile phone has started the anti-mistouch algorithm when it is determined that an obstruction is approaching the mobile phone, the mobile phone can continue to maintain the activated state of the anti-mistouch function at this time. If it is determined that no obstruction is close to the mobile phone, the mobile phone does not need to activate the anti-mistouch algorithm, and the anti-mistouch function of the mobile phone screen is in a deactivated state.
  • the determined proximity light threshold may be used to compare with the actual intensity value of the infrared reflected light reported by the proximity light sensor. If the actual light intensity value is greater than the approaching light threshold, indicating that an obstruction is approaching the mobile phone, the SensorManager may send a proximity signal to the WindowManager (window manager) of the frame layer. For example, when the proximity signal is 1, it indicates that there is an obstruction approaching the mobile phone; when the proximity signal is 0, it indicates that there is no obstruction approaching the mobile phone. In this way, after receiving the proximity signal with a value of 1, WindowManager can start the anti-missing algorithm to generate an anti-missing window on the window that the mobile phone is displaying. The anti-missing window can block any operation received on the mobile phone screen. Thus, the effect of preventing accidental touch is achieved.
  • the actual light intensity value of the infrared reflected light reported by the proximity light sensor can be updated regularly, and the status signal stored in the status manager for indicating the mobile phone's movement posture can also be updated regularly. Then, whenever SensorManager receives a change in the actual light intensity value reported by the proximity light sensor, SensorManager can use the new actual light intensity value to compare with the proximity light threshold. When the new actual light intensity value is less than the approach light threshold, SensorManager can modify the approach signal from 1 to 0 and send it to WindowManager. At this time, WindowManager can remove the above-mentioned anti-mistouch window, that is, deactivate the anti-mistouch function of the mobile phone screen, thereby restoring the interactivity between the mobile phone screen and the user.
  • SensorManager may modify the approaching light threshold with a smaller value to the approaching light threshold with a higher value. Furthermore, SensorManager can re-compare the magnitude relationship between the near-light threshold and the actual light intensity value stored at this time. If the actual light intensity value is less than the third approaching light threshold, the SensorManager may send a windowing signal 0 to the WindowManager that no obstruction is approaching the mobile phone. In this way, in response to the proximity signal 0, WindowManager may remove the above-mentioned anti-mistouch window, that is, deactivate the anti-mistouch function of the mobile phone screen, thereby restoring the interactivity between the mobile phone screen and the user. Of course, if the last proximity signal received by WindowManager is also 0, it means that the mobile phone has loaded the anti-mistouch window, then WindowManager can continue to keep the anti-touch function of the mobile phone screen in the deactivated state.
  • proximity light thresholds may be preset in the SensorManager, namely, proximity light threshold 1, proximity light threshold 2, and proximity light threshold 3.
  • the proximity light threshold 1 is 400
  • the proximity light threshold 2 is 260
  • the proximity light threshold 3 is 120.
  • the light threshold is set to a larger value close to the light threshold 1 (ie, 400). In this way, when the obstruction is close enough to the proximity light sensor, the actual light intensity value of the infrared reflected light reported by the proximity light sensor to the SensorManager will be greater than the proximity light threshold 1, which will trigger WindowManager to start the anti-mistouch algorithm
  • the window is covered with an anti-mistouch window.
  • the mobile phone when the mobile phone receives a new call event, the risk of accidental touch in the incoming call scenario is greater than the risk of accidental touch in the bright screen unlocked state, so SensorManager can approach the light threshold It is modified from the above approach light threshold 1 to the approach light threshold 2 with a smaller value (ie, 260).
  • the mobile phone can also use the gyro sensor to detect the rotation angle of the mobile phone along the y-axis. If it is detected that the rotation angle of the mobile phone along the y-axis is greater than the angle threshold, it means that the user is likely to flip the mobile phone to the ear to make a call, and at this time, the human ear is more likely to accidentally touch the mobile phone screen.
  • SensorManager can modify the approaching light threshold from the approaching light threshold 2 to the approaching light threshold 3 with a smaller value (ie, 120).
  • a smaller value ie, 120.
  • the SensorManager will send a proximity signal to the WindowManager, so that the WindowManager starts to prevent The false touch algorithm overlays a window for preventing false touch on the window being displayed by the mobile phone.
  • the size relationship between the actual light intensity value received by the proximity light sensor and the proximity light threshold is used as an example to determine whether an obstruction is approaching the mobile phone.
  • the greater the actual intensity value of the infrared reflected light the closer the distance between the blocking object and the mobile phone; the smaller the actual intensity value of the infrared reflected light, the greater the distance between the blocking object and the mobile phone.
  • the mobile phone may also calculate the energy ratio between the infrared light intensity emitted by the proximity light sensor and the actual intensity value of the infrared reflected light after reflection. Since the infrared light emitted by the proximity light sensor will lose part of its energy after being reflected, the above energy ratio is generally a positive number less than 1. In this implementation, when the calculated energy ratio is larger, it means that the actual intensity value of the infrared reflected light is smaller, that is, the distance between the blocking object and the mobile phone is farther. Therefore, after the mobile phone uses the proximity light sensor to obtain the current energy ratio (for example, 0.4), the energy ratio can be compared with the preset energy ratio (for example, 0.5). If the energy ratio is less than the preset energy ratio, it means that an obstruction is approaching the mobile phone. Furthermore, the mobile phone can enable an anti-mistouch algorithm to prevent the blocking object from accidentally touching the screen of the mobile phone.

Description

一种接近光传感器的控制方法及电子设备
本申请要求于2018年11月07日提交中国国家知识产权局、申请号为201811318527.3、发明名称为“一种接近光传感器的控制方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端领域，尤其涉及一种接近光传感器的控制方法及电子设备。
背景技术
目前，手机、平板电脑等各类终端中普遍使用了接近光传感器来确定是否有物体接近终端。以红外式的接近光传感器举例，如图1所示，该接近光传感器中包括红外发射端101和红外接收端102。其中，红外发射端101发射出红外线后，如果有遮挡物(例如人耳)将发射的红外线反射回来，则反射的红外线后可被红外接收端102接收。当红外接收端102接收到的红外线的强度超过设定的接近光阈值时，手机判断此时有遮挡物接近手机。进而，手机可启动防误触算法避免接近手机的遮挡物误触手机屏幕103。
一般，用于判断是否有遮挡物接近手机的接近光阈值是固定的。例如，可设置接近光阈值为650个计量单位，(该计量单位用于表征接收到的红外线的强度的计量单位，可以为光强度的计量单位或者是经光电转换得到的电信号的计量单位，可由手机厂商自行设定)，即当红外接收端102接收到的红外线的强度超过650个单位时可确定有遮挡物接近手机。
但是，手机的实际使用情况多种多样，固定的接近光阈值不能满足各种情况下的需要。例如，在一些情况下该接近光阈值很难达到，导致误触算法不能被启动，使得误触容易发生；而在另一些情况下接近光阈值很容易达到，误触算法经常被启动，导致用户的正常操作也不能被立即执行。因此，如何设置接近光阈值满足不同使用情况下的用户需求成为亟需解决的问题。
发明内容
本申请提供一种接近光传感器的控制方法及电子设备，可在不同使用情况下适应性调整接近光传感器的接近光阈值，从而提高激活和去激活防误触功能时的灵活性。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种接近光传感器的控制方法，可由具有接近光传感器的电子设备执行，该方法包括：检测到满足调整条件，该调整条件包括：电子设备的运动姿态为设定的目标运动姿态；将接近光传感器的第一接近光阈值改为第二接近光阈值(第一接近光阈值与第二接近光阈值不同)；获取接近光传感器上报的光强参数，该光强参数用于表示该接近光传感器发射光的反射光强；根据该光强参数和第二接近光阈值，激活或去激活电子设备的屏幕的防误触功能。
也就是说，在本申请实施例提供的接近光传感器的控制方法中，电子设备可以结合手机当前的运动姿态确定出相应的接近光阈值。由于电子设备的运动姿态可反映出电子设备当前所处的具体场景，这样，当电子设备处于不同的运动姿态时一般处于不同的使用场景中，电子设备可使用不同的接近光阈值判断是否激活触摸屏的防误触功能，从而提高激活和去激活防误触功能时的灵活性。
在一种可能的设计方法中，上述目标运动姿态具体包括：电子设备的重力在设定方向上 的分量大于设定值，该设定方向为从电子设备底部指向电子设备顶部的方向。一般，当重力在该设定方向上的分量大于设定值时，电子设备大多处于顶部朝下的状态，此时，电子设备一般处于口袋场景中。也就是说，当检测出电子设备处于顶部朝下的状态时，电子设备可动态调整接近光传感器的接近光阈值。当然，本领域技术人员还可以根据实际应用场景或实际经验设置检测电子设备顶部朝下的具体方法，本申请实施例对此不做任何限制。
在一种可能的设计方法中，上述目标运动姿态包括：电子设备的重力在该设定方向上的分量逐渐增大至大于设定值，该设定方向为从电子设备底部指向电子设备顶部的方向。一般，当重力在上述设定方向上的分量逐渐增大至设定值时，说明电子设备的运动姿态逐渐转换为顶部朝下的状态，通常是用户将电子设备放入口袋的过程中会发生这一运动姿态的转换。因此，当检测出重力在上述设定方向上的分量逐渐增大至设定值时，电子设备可动态调整接近光传感器的接近光阈值。
在一种可能的设计方法中，上述调整条件还包括：检测到锁屏事件或灭屏事件。
一般，检测到锁屏事件或灭屏事件，如果电子设备处于头部朝下或转换为头部朝下的状态，说明电子设备很可能处于口袋场景中。此时，靠近电子设备的遮挡物更容易接触到电子设备的屏幕产生误触操作。因此，电子设备可将接近光阈值设置为取值较小。这样，如果接近光传感器检测到反射光的强度大于该接近光阈值，电子设备便可开启防误触算法屏蔽触摸屏检测到的触摸操作，从而降低电子设备发生的误触现象的几率。
在一种可能的设计方法中，上述目标运动姿态包括：电子设备围绕设定方向旋转的旋转角度大于角度阈值，该设定方向为从电子设备底部指向电子设备顶部的方向。一般，当电子设备围绕上述设定方向旋转的角度大于角度阈值时，说明电子设备处于翻转状态。由于用户使用听筒接听电话时通常会翻转手机至耳边，使电子设备围绕上述设定方向产生一定角度的旋转，因此，当电子设备围绕上述设定方向旋转的角度大于角度阈值时，电子设备很可能处于贴耳通话的场景中。
进一步地，用户使用听筒接听电话时通常需要将手机抬起至耳边，此时，电子设备处于抬手运动姿态。那么，上述目标运动姿态还包括：电子设备在至少一个方向上产生的加速度逐渐增大至大于第一设定值后，逐渐减小至小于第二设定值(第一设定值大于第二设定值)。如果检测到电子设备的运动姿态为上述目标运动姿态，说明电子设备既处于翻转状态，同时还处于抬手运动姿态，此时用户使用电子设备进行贴耳通话的可能性更大。因此，当检测出电子设备围绕上述设定方向旋转的角度大于角度阈值，且电子设备在至少一个方向上产生的加速度逐渐增大至大于第一设定值后，逐渐减小至小于第二设定值后，电子设备可动态调整接近光传感器的接近光阈值。当然，本领域技术人员可以根据实际应用场景或实际经验设置检测电子设备处于翻转状态和抬手运动姿态的具体方法，本申请实施例对此不做任何限制。
在一种可能的设计方法中，上述调整条件还包括：检测到来电事件或拨号事件。
一般，检测到来电事件或拨号事件后，如果电子设备的运动状态为上述目标运动状态，说明用户很可能在使用电子设备进行贴耳通话。此时，靠近电子设备的遮挡物(例如人耳)更容易接触到电子设备的屏幕产生误触操作。因此，电子设备可将接近光阈值设置为取值较小。这样，如果接近光传感器检测到反射光的强度大于该接近光阈值，电子设备便可开启防误触算法屏蔽触摸屏检测到的触摸操作，从而降低电子设备发生的误触现象的几率。
相应的，在发生误触操作的可能相对较低的应用场景下，电子设备可使用取值较大的接近光阈值判断是否有遮挡物。此时，电子设备判断是否有遮挡物接近的要求较为严格，相应 使得电子设备开启防误触算法的条件较为严格，从而尽可能的降低因频繁启动防误触算法导致用户正常操作被屏蔽的几率。
在一种可能的设计方法中，上述光强参数可以是指接近光传感器接收到的反射光强，或该反射光强与该接近光传感器的发射光强的比值；第一接近光阈值大于第二接近光阈值；其中，根据光强参数和第二接近光阈值，激活或去激活电子设备的屏幕的防误触功能，包括：若该光强参数大于第二接近光阈值，说明有遮挡物接近电子设备，则可激活电子设备的屏幕的防误触功能，或保持电子设备的屏幕的防误触功能为激活状态。
或者，若上述光强参数小于第二接近光阈值，说明没有遮挡物接近电子设备，则电子设备可以去激活触摸屏的防误触功能，或保持电子设备的触摸屏的防误触功能为去激活状态。
在一种可能的设计方法中，上述光强参数可以是指接近光传感器的发射光强与接近光传感器接收到的反射光强的比值，或该接近光传感器的发射光强的光损失率；第一接近光阈值小于第二接近光阈值；其中，根据光强参数和第二接近光阈值，激活或去激活电子设备的屏幕的防误触功能，包括：若该光强参数小于第二接近光阈值，说明有遮挡物接近电子设备，则可激活电子设备的屏幕的防误触功能，或保持电子设备的屏幕的防误触功能为激活状态。
或者，若上述光强参数大于第二接近光阈值，说明没有遮挡物接近电子设备，则电子设备可以去激活触摸屏的防误触功能，或保持电子设备的触摸屏的防误触功能为去激活状态。
第二方面，本申请提供一种电子设备，包括：接近光传感器、加速度传感器、陀螺仪传感器触摸屏、一个或多个处理器、一个或多个存储器、以及一个或多个计算机程序；其中，处理器与接近光传感器、加速度传感器、陀螺仪传感器触摸屏以及存储器均耦合，上述一个或多个计算机程序被存储在存储器中，当电子设备运行时，该处理器执行该存储器存储的一个或多个计算机程序，以使电子设备执行上述任一项所述的接近光传感器的控制方法。
第三方面，本申请提供一种计算机存储介质，包括计算机指令，当计算机指令在电子设备上运行时，使得电子设备执行如第一方面中任一项所述的接近光传感器的控制方法。
第四方面，本申请提供一种计算机程序产品，当计算机程序产品在电子设备上运行时，使得电子设备执行如第一方面中任一项所述的接近光传感器的控制方法。
可以理解地，上述提供的第二方面所述的终端、第三方面所述的计算机存储介质，以及第四方面所述的计算机程序产品均用于执行上文所提供的对应的方法，因此，其所能达到的有益效果可参考上文所提供的对应的方法中的有益效果，此处不再赘述。

在本申请实施例中，上述传感器模块180还可以包括陀螺仪传感器180B和/或加速度传感器180E。
其中，通过陀螺仪传感器180B可以确定手机100围绕三个轴(即x，y和z轴)的旋转角度。一般，如图3所示放置手机时，手机的顶部在上，底部在下。如图3所示的一个右手笛卡尔坐标系包括x轴，y轴和z轴。其中，手机100的屏幕较短边所在的轴作为x轴，手机100的屏幕较长边所在的轴为y轴，y轴从手机的底部指向屏幕的顶部，垂直于x轴和y轴所在平面的轴为z轴，z轴从x轴和y轴定义的平面向外指向。示例性的，从用户查看来电信息到用户使用听筒接听电话的过程中，手机100一般会围绕y轴产生90°左右的旋转。那么，当陀螺仪传感器180B检测到手机100围绕y轴的旋转角度大于某一阈值(例如80°)时，手机的运动姿态一般为翻转状态。如果手机100此时处于通话状态，则说明用户很可能在使用手机100进行贴耳通话，即用户处于贴耳通话场景中。
加速度传感器180E可检测手机100在各个方向(一般为x，y和z轴)上加速度的大小。当手机100静止时加速度传感器180E可检测出重力的大小及方向。示例性的，如图4所示，如果加速度传感器180E检测出重力的方向指向手机100的顶部(即，重力的方向沿着y轴指向伸的方向)，或者，检测出重力沿手机100顶部方向的分量大于设定值(即，重力的方向沿着y轴分量大于设定值)，手机的运动姿态一般为顶部朝下的状态，说明此时手机100很有可能被用户放在口袋或包中。当然，手机100还可以根据其他信息确定手机100是否被用户放在口袋或包中。例如，如果加速度传感器180E检测出重力的方向指向手机100的顶部，且环境光传感器180L检测到环境光的强度小于阈值，则说明此时手机100很有可能被用户放在口袋或包中。
为方便描述，后续实施例中可将陀螺仪传感器180B检测到的旋转角度等信息称为陀螺仪传感器180B的测量值，将加速度传感器180E检测到的重力的大小和方向等信息称为加速度传感器180E的测量值。陀螺仪传感器180B和加速度传感器180E的测量值可反映出手机100的运动姿态以及用户在使用手机100时所处的应用场景。
在本申请实施例中，传感器模块180还包括接近光传感器180G。接近光传感器180G可以包括发光二极管(LED)和光检测器。发光二极管可作为接近光传感器180G的发射端，例如，发光二极管可以是红外发光二极管。手机100通过发光二极管向外发射红外光。光检测器(例如光电二极管)可作为接近光传感器180G的接收端。手机100使用光检测器可检测来自附 近遮挡物的红外反射光，将接收到的红外反射光转换为电信号并进行量化，得到红外反射光的强度。红外反射光的强度的计量单位可以根据需要选择，本发明实施例对此不做限定，后续描述红外反射光的强度和接近光阈值时，省略了计量单位。当检测到红外反射光的强度大于设定的接近光阈值时，可以确定手机100附近有遮挡物。当检测到红外反射光的强度小于接近光阈值时，手机100可以确定手机100附近没有遮挡物。
在本申请实施例中，上述接近光阈值可以有至少两个。在锁屏状态或通话状态下，手机100可以根据上述陀螺仪传感器180B或加速度传感器180E的测量值，选择使用哪一个接近光阈值判断手机100附近是否有遮挡物。进而，当手机100附近有遮挡物时，手机100可开启防误触算法防止遮挡物误触手机100的屏幕。
例如，手机100可设定第一接近光阈值和第二接近光阈值(第一接近光阈值＜第二接近光阈值)。当陀螺仪传感器180B的测量值反映出手机的运动姿态为翻转状态时，说明用户很可能处于贴耳通话的场景中。此时，靠近手机的遮挡物(例如人耳)更容易接触到手机100的屏幕产生误触操作。如果将接近光阈值设置为取值较大的第二接近光阈值，则接近光传感器180G检测到红外反射光光强很难达到该接近光阈值，导致误触算法不能被启动从而发生误触。因此，手机100可将接近光阈值设置为取值较小的第一接近光阈值。这样一来，如果接近光传感器180G检测到红外反射光的强度大于第一接近光阈值，手机100便可开启防误触算法屏蔽手机100屏幕检测到的触摸操作，即对屏幕检测到的触摸操作不响应，从而降低手机100发生的误触现象的几率。
类似的，当加速度传感器180E的测量值反映出手机的运动姿态为顶部朝下的状态时，说明手机很可能处于口袋场景中。此时，靠近手机的遮挡物更容易接触到手机100的屏幕产生误触操作。如果将接近光阈值设置为取值较大的第二接近光阈值，则接近光传感器180G检测到红外反射光光强很难达到该接近光阈值，导致误触算法不能被启动从而发生误触。因此，手机100可将接近光阈值设置为取值较小的第一接近光阈值。这样一来，如果接近光传感器180G检测到红外反射光的强度大于第一接近光阈值，手机100便可开启防误触算法屏蔽手机100屏幕检测到的触摸操作，即对屏幕检测到的触摸操作不响应，从而降低手机100发生的误触现象的几率。
本申请实施例中可将手机处于翻转状态或顶部朝下状态等运动姿态称为目标运动姿态。在目标运动姿态下，手机屏幕发生误触操作的风险较大。
那么，如果检测到手机100的运动姿态未处于上述目标运动姿态，或者，检测到手机100从上述目标运动姿态中退出，则相对于处于目标运动姿态的手机100而言，手机屏幕发生误触操作的可能降低。如果此时继续将接近光阈值设置为取值较大的第二接近光阈值，则接近光传感器180G检测到红外反射光光强容易到该接近光阈值，导致防误触算法频繁被启动从而干扰用户的正常操作。因此，手机100可将接近光阈值设置为取值较大的第二接近光阈值。这样一来，当接近光传感器180G检测到红外反射光的强度大于第二接近光阈值时，手机100才会开启防误触算法屏蔽手机100屏幕检测到的触摸操作，从而不影响用户的正常操作。因此，防误触算法的启动能够适应各种场景。
也就是说，在本申请实施例提供的接近光传感器的控制方法中，手机100可结合手机100当前的运动姿态确定出相应的接近光阈值。由于手机100的运动姿态可反映出手机100当前所处的具体场景，在比较容易发生误触操作的应用场景下，手机100可使用取值较小的接近光阈值判断是否有遮挡物。此时，即使接近光传感器180G发出的一部分红外光被吸收了， 手机100也可判断出有遮挡物接近。这样，手机100判断是否有遮挡物接近的要求较为宽松，相应使得手机100开启防误触算法的条件较为宽松，从而尽可能的降低了手机100发生误触现象的几率。而在发生误触操作的可能相对较低的应用场景下，手机100可使用取值较大的接近光阈值判断是否有遮挡物。手机100判断是否有遮挡物接近的要求较为严格，相应使得手机100开启防误触算法的条件较为严格，从而尽可能的降低因频繁启动防误触算法导致用户正常操作被屏蔽的几率。
当然，上述传感器模块180还可以包括压力传感器180A，气压传感器180C，磁传感器180D，距离传感器180F，指纹传感器180H，温度传感器180J，触摸传感器180K，环境光传感器180L，骨传导传感器180M等，本申请实施例对此不做任何限制。其中，触摸传感器180K，也称“触控面板”。触摸传感器180K可以设置于显示屏194，由触摸传感器180K与显示屏194组成触摸屏，也称“触控屏”。触摸传感器180K用于检测作用于其上或附近的触摸操作。触摸传感器可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。可以通过显示屏194提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器180K也可以设置于手机100的表面，与显示屏194所处的位置不同。
手机100还可以包括USB接口130、充电管理模块140、电源管理模块141、电池142以及SIM卡接口195等部件，本申请实施例对此不做任何限制。
手机100的软件系统可以采用分层架构，事件驱动架构，微核架构，微服务架构，或云架构。本申请实施例以分层架构的Android系统为例，示例性说明手机100的软件结构。
图5是本发明实施例的手机100的软件结构框图。
分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过接口通信。在一些实施例中，将Android系统分为四层，从上至下分别为应用程序层，应用程序框架层，安卓运行时(Android runtime)和系统库，以及内核层。
应用程序层可以包括一系列应用程序包。
如图5所示，应用程序包可以包括相机，图库，日历，通话，地图，导航，WLAN，蓝牙，音乐，视频，短信息等应用程序。
这些应用程序可以是操作系统的系统级应用(例如，桌面、短信、通话、日历、联系人等)，也可以是普通级别应用(例如，微信、亚马逊等)。系统级应用一般指的是：该应用具有系统级权限，可以获取各种系统资源。普通级别应用一般指的是：该应用具有普通权限，可能无法获取某些系统资源，或者需要用户授权，才能获取一些系统资源。系统级应用可以为手机中预装的应用。普通级别应用可以为手机中预装的应用，也可以为后续用户自行安装的应用。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图5所示，应用程序框架层可以包括窗口管理器，传感器管理器，状态管理器，内容提供器，视图系统，电话管理器，通知管理器等。
窗口管理器(WindowManager)用于管理窗口程序。例如，窗口管理器可以按照防误触算法在正在显示的窗口上加载一个防误触窗口，从而激活手机屏幕的防误触功能。该防误触窗口可以是透明、半透明或不透明的。加载防误触窗口后，手机将不再响应手机屏幕上接收到的任何操作，直至窗口管理器移除该防误触窗口。当然，窗口管理器还可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。
传感器管理器(SensorManager)可用于获取内核层的传感器驱动上报的传感器事件。以接近光传感器为例，接近光传感器在工作的过程中可将检测到的红外反射光的强度通过传感器驱动上报给传感器管理器。
状态管理器可根据陀螺仪传感器和加速度传感器上报的测量值确定手机的运动姿态。例如，当陀螺仪传感器上报的手机围绕y轴的旋转角度大于设定的角度时，状态管理器可向传感器管理器输出状态信号1，用于指示手机所处的运动姿态为翻转状态。又例如，例如，当加速度传感器上报的重力方向与y轴的指向重合时，状态管理器可向传感器管理器输出状态信号0，用于指示手机所处的运动姿态为顶部朝下的状态。
内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。
视图系统包括可视控件，例如显示文字的控件，显示图片的控件等。视图系统可用于构建应用程序。显示界面可以由一个或多个视图组成的。例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。
电话管理器用于提供手机100的通信功能。例如通话状态的管理(包括接通，挂断等)。
通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息，发出提示音，终端振动，指示灯闪烁等。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓系统的调度和管理。
核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心库。
应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理，堆栈管理，线程管理，安全和异常的管理，以及垃圾回收等功能。
系统库可以包括多个功能模块。例如：表面管理器(surface manager)，媒体库(Media Libraries)，三维图形处理库OpenGL ES，2D图形引擎SGL等。
表面管理器用于对显示子系统进行管理，并且为多个应用程序提供了2D和3D图层的融合。
媒体库支持多种常用的音频，视频格式回放和录制，以及静态图像文件等。媒体库可以支持多种音视频编码格式，例如：MPEG4，H.264，MP3，AAC，AMR，JPG，PNG等。
OpenGL ES用于实现三维图形绘图，图像渲染，合成，和图层处理等。
SGL是2D绘图的绘图引擎。
内核层是硬件和软件之间的层。内核层至少包含显示驱动，摄像头驱动，音频驱动，传感器驱动。
在本申请实施例中，硬件中的接近光传感器检测到红外反射光后，可通过内核层的传感器驱动将红外反射光的强度上报给传感器管理器。同样，硬件层的陀螺仪传感器和加速度传感器也可以将检测到的旋转角度、加速度值以及重力方向等测量值上报给状态管理器，状态管理器可根据这些测量值确定出手机所处的具体运动姿态。进而，传感器管理器可根据状态管理器确定出的手机所处的运动姿态，选择相应的接近光阈值作为判断是否有遮挡物接近的标准。
例如，当状态管理器确定当前手机处于顶部朝下或翻转状态等目标运动姿态时，由于此时靠近手机的遮挡物容易接触到手机的屏幕产生误触操作，因此，传感器管理器可使用取值较小的第一接近光阈值作为本次判断是否有遮挡物接近手机的接近光阈值。进而，传感器管理器可比较该第一接近光阈值与红外反射光的强度，如果红外反射光的强度大于第一接近光阈值，则说明有遮挡物接近手机。那么，传感器管理器可上报窗口管理器有遮挡物接近，触发窗口管理器开启防误触算法，在当前显示的窗口上生成并加载防误触窗口，避免手机发生误触现象。这样一来，在比较容易发生误触操作的场景下，传感器管理器通过取值较小的第一接近光阈值可以将判断出有遮挡物接近手机的条件变得更为宽松，从而及时通知窗口管理器生成防误触窗口以降低手机发生误触现象的几率。
以下将以手机作为电子设备举例，结合附图详细阐述本申请实施例提供的一种接近光传感器的控制方法。
在一些实施例中，当手机处于黑屏(或称为息屏)状态时，一般说明用户没有使用手机的需求，因此，手机可以关闭接近光传感器，或者，手机也可以以较低的工作频率(即低功耗模式)开启接近光传感器进行工作，以节省手机功耗。当然，当手机处于黑屏或息屏状态时，手机还可以关闭陀螺仪传感器或加速度传感器等其他传感器，本申请实施例对此不做任何限制。
如果手机在黑屏状态时接收到新的消息(或来电)，或者，有物体触发了手机上的按键，手机会从黑屏状态切换为亮屏状态。此时，如果接近光传感器已经关闭，则手机可开启接近光传感器进行正常工作。如果接近光传感器处于工作频率较低的低功耗模式，则手机可提高接近光传感器的工作频率，使接近光传感器开始正常工作。类似的，如果手机从黑屏状态切换为亮屏状态，手机还可以控制陀螺仪传感器、加速度传感器等用于确定手机运动姿态的其他传感器开始正常工作。
当加速度传感器工作时，加速度传感器可定期检测重力的大小及方向。示例性的，如图6中的(a)所示，可将手机的四个顶点中的任意一点(例如左下角的顶点)作为前述的右手笛卡尔坐标系的原点O，其中，x轴，y轴和z轴的描述参见前述实施例的定义。那么，加速度传感器可检测出重力G在上述坐标系中的大小和方向。如图6中的(b)所示，当重力G的方向与y轴的指向重合时，说明重力G此时指向手机的顶部。也就是说，手机可根据重力G在y轴上的分量确定手机的运动姿态是否为顶部朝下。因此，加速度传感器可将重力G在y轴上的分量上报给框架层的状态管理器。进而，状态管理器可根据重力G在y轴上的分量确定手机此时的运动姿态是否为顶部朝下的状态。如果重力G在y轴上的分量与y轴的指向相同，且重力G在y轴上的分量大于设定的分量，则状态管理器可向传感器输出状态信号0，用于指示手机所处的运动姿态为顶部朝下的目标运动姿态。当手机处于顶部朝下的运动姿态时，此时手机很可能处于口袋场景中。
或者，用户将手机放入口袋的过程一般是先大致水平的握持手机将手机锁屏，进而将手机顶部朝下放入口袋。因此，可以设置上述目标运动姿态是指手机从顶部朝上转变为顶部朝下的姿态变化过程。示例性的，当手机检测到用户对手机执行锁屏操作后，手机可使用加速度传感器检测并记录重力G在上述坐标系中的变化过程。仍参考前述实施例中的右手笛卡尔坐标系说明如下(图7未示出)，如图7中的(a)所示，手机刚锁屏后用户一般仍处于屏幕大致水平的正常观看手机的姿态，此时重力G与坐标系的z轴重合。在用户将手机放入口袋的过程中，如图7中的(b)-(d)所示，重力G的方向逐渐与坐标系中y轴的指向重合，即 手机的运动姿态从顶部朝上逐渐转变为顶部朝下。那么，如果加速度传感器检测到的重力G的变化过程与图7所示的变化过程相符，则状态管理器也可确定手机处于目标运动姿态。
当陀螺仪传感器工作时，仍以图6中的(a)-(b)中所示的坐标系举例，陀螺仪传感器可定期检测手机围绕y轴的旋转角度
Figure PCTCN2019110066-appb-000001
进而，加速度传感器可将检测到的手机围绕y轴的旋转角度
Figure PCTCN2019110066-appb-000002
上报给框架层的状态管理器。当手机围绕y轴的旋转角度
Figure PCTCN2019110066-appb-000003
大于设定的角度(例如80°)时，状态管理器向传感器输出状态信号1，用于指示手机所处的运动姿态为翻转状态这一目标运动姿态。当手机处于翻转状态时，如果手机此时处于通话状态，则说明此时手机很可能处于贴耳通话场景中。当然，本申请实施例对手机检测是否处于翻转状态和是否处于通话状态的先后顺序不作任何限定。
示例性的，用户从接听电话到使用手机顶部听筒进行通话时，一般是先握持手机查看来电信息或进行拨号，再翻转手机至耳边进行通话。因此，如图8中的(a)所示，当手机接收到新的来电或检测到用户点击拨号按钮时，手机可使用陀螺仪传感器记录手机此时沿y轴的角度，即手机开始围绕y轴旋转的初始角度
Figure PCTCN2019110066-appb-000004
进而，如图8中的(b)-(c)所示，用户在翻转手机的过程中，手机可使用陀螺仪传感器连续记录手机围绕y轴从初始角度
Figure PCTCN2019110066-appb-000005
开始旋转的旋转角度
Figure PCTCN2019110066-appb-000006
当旋转角度
Figure PCTCN2019110066-appb-000007
大于角度阈值时，可确定手机此时处于目标运动姿态。当然，手机也可以连续记录手机围绕y轴旋转的实际角度
Figure PCTCN2019110066-appb-000008
直至检测到手机停止围绕y轴旋转时的结束角度
Figure PCTCN2019110066-appb-000009
当结束角度
Figure PCTCN2019110066-appb-000010
与初始角度
Figure PCTCN2019110066-appb-000011
的差值大于角度阈值时，手机也可确定此时处于目标运动姿态。
另外，如图9所示，由于用户使用手机顶部听筒接听通话时一般会产生抬手的动作，因此，在检测手机围绕y轴的旋转角度
Figure PCTCN2019110066-appb-000012
的同时，手机还可以使用加速度传感器等识别手机是否处于抬手运动姿态。例如，用户举起手机的过程中手机在x轴、y轴以及z轴上会产生相应的加速度，这个加速度一般在一个阈值区间内。而用户举起手机后手机一般处于静止(或趋于静止)的状态，此时检测到的加速度趋近于0。那么，如果加测到手机在x轴、y轴以及z轴上产生的加速度落入上述阈值区间后又回到0，则可确定手机处于抬手运动姿态，即用户执行了抬手操作。因此，在一些实施例中，如果检测到手机围绕y轴的旋转角度

大于角度阈值，且手机在x轴、y轴或z轴上产生的加速度逐渐增大直至落入设定的阈值区间后，该加速度又渐减小至趋近于0，则手机也可确定此时处于目标运动姿态，即目标运动姿态包括翻转状态和抬手运动姿态。
示例性的，状态管理器可以将为手机确定出的状态信号存储下来并定时更新，例如，手机可在状态管理器中设置一个或多个比特的标志位，该标志位用于存储状态信号。例如，当状态信号为00时，说明手机处于顶部朝下的运动姿态，当状态信号为01时，说明手机处于翻转姿态。状态管理器可以将最近一次确定出的状态信号保存在该标志位中。
进一步地，当接近光传感器开始工作时，接近光传感器可以一定频率发射光线(后续实施例中以接近光传感器发射红外光举例)，如果手机附近有遮挡物，则接近光传感器会接收到红外光反射后的红外反射光。那么，接近光传感器可以将每次接收到的红外反射光的实际光强值上报给框架层的SensorManager(传感器管理器)。SensorManager内可设置存储单元存储最近一次接近光传感器上报的红外反射光的实际光强值。并且，SensorManager内还可以预先存储多个接近光阈值，这些接近光阈值可分别用于在手机处于不同运动姿态时判断是否有遮挡物接近，例如，SensorManager内存储有第一接近光阈值、第二接近光阈值以及第三接近光阈值，其中，第一接近光阈值＜第二接近光阈值＜第三接近光阈值。
那么，SensorManager获取到最近一次接近光传感器上报的实际光强值后，可以从状态管理器进一步获取用于指示手机运动姿态的状态信号。如果手机所处的手机运动姿态为设定的目标运动姿态，则说明手机很可能处于发生误触风险较高的场景(例如上述口袋场景或贴耳通话场景)，则SensorManager可以使用取值较小的接近光阈值(例如上述第一接近光阈值或第二接近光阈值)判断是否有遮挡物接近。由于上述第一接近光阈值或第二接近光阈值的取值相对较小，因此判断出有遮挡物接近手机的可能性较大，相应的，后续手机开启防误触算法的可能性较大，从而降低手机在这些发生误触风险较高的场景下发生误触的几率。
当然，如果手机所处的手机运动姿态不是上述目标运动姿态，则手机屏幕发生误触操作的可能降低。此时，SensorManager可以使用取值较大的接近光阈值(例如上述第三接近光阈值)判断是否有遮挡物接近。这样一来，SensorManager判断是否有遮挡物接近的要求较为严格，相应使得手机开启防误触算法的条件较为严格，从而尽可能的降低因频繁启动防误触算法导致用户正常操作被屏蔽的几率。
需要说明的是，如图10所示，手机除了可以根据当前的运动姿态动态调整上述接近光阈值外，还可以结合手机在运行时的其他信息确定如何调整上述接近光阈值。也就是说，手机可以设定一个触发调整接近光阈值的调整条件，该调整条件至少包括手机处于上述目标运动姿态这一条件，该调整条件还可以包括手机屏幕的状态信息(例如解锁事件、锁屏事件)、通话状态信息(例如拨号事件、来电事件)等满足设定的条件。当检测到手机满足上述调整条件时，手机可动态调整上述接近光阈值。
例如，在调整上述接近光阈值之前，手机还可以获取手机的屏幕状态信息。例如，如果检测到手机屏幕已经解锁，则说明用户可能在正常使用手机，因此，为了避免经常防误触算法开启后屏蔽用户的正常操作，手机可以将上述接近光阈值设置为取值较大的第三接近光阈值。相应的，如果检测到手机屏幕没有解锁，且手机处于顶部朝下的目标运动姿态，则手机发生误触风险较高，因此，手机可以将上述接近光阈值设置为取值较小的第一接近光阈值或第二接近光阈值。或者，如果检测到针对手机屏幕的锁屏事件(或灭屏事件)后，继续检测到重力在上述y轴上的分量逐渐增大，直至重力在上述y轴上的分量大于设定值，说明用户很可能将手机锁屏后装入口袋中，因此，手机可将上述接近光阈值设置为取值较小的第一接近光阈值或第二接近光阈值。
又例如，在调整上述接近光阈值之前，手机还可以获取当前的通话状态信息。例如，如果检测到手机没有运行通话应用，则说明手机当前不在通话状态中，则手机可将上述接近光阈值设置为取值较大的第三接近光阈值。如果手机检测到来电事件或用户输入的拨号事件，且手机围绕y轴的旋转角度

大于角度阈值，则说明手机处于通话状态，且用户很可能是以贴耳姿态进行通话的，那么，手机可将上述接近光阈值设置为取值较小的第一接近光阈值或第二接近光阈值。
又例如，在调整上述接近光阈值之前，手机还可以获取当前的环境光信息。例如，手机可以使用环境光传感器检测当前的环境光光强。如果当前的环境光光强小于光强阈值，且手机处于顶部朝下的目标运动姿态，则说明手机很可能处于口袋场景中。因此，手机可以将上述接近光阈值设置为取值较小的第一接近光阈值或第二接近光阈值。
另外，手机在口袋场景下一般会随用户移动，那么，手机可使用定位装置、陀螺仪传感器或加速度传感器检测手机是否处于步行、乘车等移动状态。因此，手机设定的目标运动姿态还可以包括移动状态。如果检测到手机处于移动状态，且处于顶部朝下的目标运动姿态， 则手机可以将上述接近光阈值设置为取值较小的第一接近光阈值或第二接近光阈值。
可以看出，如图10所示，在本申请实施例中手机可以根据加速度传感器和陀螺仪传感器的测量值确定手机所处的运动姿态。进而，手机可结合手机的运动姿态、环境光光强、手机的通话状态以及手机的屏幕状态等信息确定手机是否满足了设定的调整条件。如果满足该调整条件，则手机可动态调整接近光传感器的接近光阈值。例如，在误触风险相对较大的情况下，手机可使用取值较小的接近光阈值判断是否有遮挡物接近手机，在误触风险相对较小的情况下，手机可使用取值较大的接近光阈值判断是否有遮挡物接近手机。如果确定出有遮挡物接近手机，则手机可启动防误触算法使手机屏幕的防误触功能处于激活状态。当然，如果在判断出有遮挡物接近手机时手机已经启动了防误触算法，则手机此时可继续保持防误触功能的激活状态。如果确定出没有遮挡物接近手机，则手机无需启动防误触算法，此时手机屏幕的防误触功能处于去激活状态。
示例性的，SensorManager确定了当前使用的接近光阈值后，可使用确定出的接近光阈值与接近光传感器上报的红外反射光的实际光强值进行比较。如果实际光强值大于该接近光阈值，说明有遮挡物接近手机，则SensorManager可向框架层的WindowManager(窗口管理器)发送接近信号。例如，当接近信号为1时，表示有遮挡物接近手机；当接近信号为0时，表示没有遮挡物接近手机。这样，WindowManager接收到取值为1的接近信号后，可启动防误触算法在手机正在显示的窗口上生成一个防误触窗口，该防误触窗口可以屏蔽手机屏幕上接收到的任意操作，从而达到防误触的效果。
另外，接近光传感器上报的红外反射光的实际光强值可以定期更新，状态管理器中存储的用于指示手机运动姿态的状态信号也可以定期更新。那么，每当SensorManager接收到接近光传感器上报的实际光强值发生变化，SensorManager可使用新的实际光强值与接近光阈值进行比较。当新的实际光强值小于接近光阈值时，SensorManager可将接近信号从1修改为0，并发送给WindowManager。此时，WindowManager可移除上述防误触窗口，即去激活手机屏幕的防误触功能，从而恢复手机屏幕与用户的可交互性。
又或者，如果状态管理器检测到手机退出了的上述目标运动姿态，SensorManager可将原本取值较小的接近光阈值修改为取值较高的接近光阈值。进而，SensorManager可重新比较该接近光阈值与此时存储的实际光强值之间的大小关系。如果实际光强值小于上述第三接近光阈值，则SensorManager可向WindowManager发送没有遮挡物接近手机的接近信号0。这样，响应于该接近信号0，WindowManager可移除上述防误触窗口，即去激活手机屏幕的防误触功能，从而恢复手机屏幕与用户的可交互性。当然，如果WindowManager最近一次接收到的接近信号也为0，则说明手机已经加载了防误触窗口，那么WindowManager可继续保持手机屏幕的防误触功能为去激活状态。
示例性的，SensorManager中可预先设置三个接近光阈值，即接近光阈值1、接近光阈值2以及接近光阈值3。其中，接近光阈值1为400，接近光阈值2为260，接近光阈值3为120。
那么，如图11所示，如果检测到手机处于亮屏状态，且处于解锁状态，此时用户一般在正常使用手机，出现误触现象的几率相对较小，因此，SensorManager可将此时的接近光阈值设置为较大取值的接近光阈值1(即400)。这样，当遮挡物距离接近光传感器足够近时，接近光传感器向SensorManager上报的红外反射光的实际光强值才会大于上述接近光阈值1，进而触发WindowManager启动防误触算法在手机正在显示的窗口上覆盖一个防误触窗口。
后续，仍如图11所示，当手机接收到新的来电事件时，由于在来电场景下发生误触的风 险大于在亮屏解锁态下发生误触的风险，因此，SensorManager可将接近光阈值从上述接近光阈值1修改为取值较小的接近光阈值2(即260)。同时，手机还可以使用陀螺仪传感器检测手机沿y轴的旋转角度。如果检测到手机沿y轴的旋转角度大于角度阈值，则说明用户很可能将手机翻转至耳边接打电话，此时人耳更容易误触手机屏幕。因此，SensorManager可将接近光阈值从上述接近光阈值2修改为取值更小的接近光阈值3(即120)。这样，当遮挡物(例如人耳)靠近手机时，一旦接近光传感器向SensorManager上报的红外反射光的实际光强值大于上述接近光阈值3，SensorManager便会向WindowManager发送接近信号，使得WindowManager启动防误触算法在手机正在显示的窗口上覆盖一个防误触窗口。
需要说明的是，上述实施例中是通过比较接近光传感器接收到的实际光强值与接近光阈值之间的大小关系为例判断是否有遮挡物接近手机的。在这种实现方式中，红外反射光的实际光强值越大，说明遮挡物与手机的距离越近；红外反射光的实际光强值越小，说明遮挡物与手机的距离越远。
但是，在另一些实施例中，手机也可以计算接近光传感器发出的红外光光强与经反射后红外反射光的实际光强值之间的能量比值。由于接近光传感器发出的红外光经反射后会有一部分能量损失，因此，上述能量比值一般为小于1的正数。在这种实现方式中，当计算出的能量比值越大时，说明红外反射光的实际光强值越小，即遮挡物与手机的距离越远。因此，手机使用接近光传感器获取到本次的能量比值(例如0.4)后，可将该能量比值与预设能量比值(例如0.5)比较。如果该能量比值小于预设能量比值，则说明有遮挡物接近手机。进而，手机可开启防误触算法防止遮挡物误触手机屏幕。
或者，在另一些实施例中，手机也可以计算接近光传感器发出的红外光经反射后的能量损失率。例如，接近光传感器发出的红外光光强为100，如果接近光传感器接收到的红外反射光的实际光强值为60，则其能量损失率为(100-60)/100＝0.4。同样，在这种实现方式中，当能量损失率越大时，说明红外反射光的实际光强值越小，即遮挡物与手机的距离越远。因此，手机使用接近光传感器获取到本次的能量损失率后，可将该能量损失率与预设损失率比较。如果该能量损失率小于预设损失率，则说明有遮挡物接近手机。进而，手机可开启防误触算法防止遮挡物误触手机屏幕。
那么，与上述实施例不同的是，如果手机使用上述预设能量比值(或预设损失率)判断是否有遮挡物接近手机，则当上述预设能量比值(或预设损失率)取值越大时，手机判断出有遮挡物接近手机的可能性较大，后续手机开启防误触算法的可能性较大。因此，手机获取到当前所处的场景为口袋场景或贴耳通话场景后，手机可使用取值较高的预设能量比值(或预设损失率)判断是否有遮挡物接近手机，从而增加手机开启防误触算法的几率，降低手机在这些容易发生误触的场景中被误触的几率。
也就是说，在本申请实施例中，手机可在口袋场景或贴耳通话场景等容易发生误触的场景中，调整用于判断是否有遮挡物接近手机时使用的阈值，该阈值可以是上述接近光阈值、预设比值或预设损失率，使得手机判断出有遮挡物接近的判断条件更加宽松，从而提高了手机开启防误触算法的几率，降低了手机发生的误触现象几率。
另外，本申请实施例中不限制上述防误触算法的具体实现方式。例如，上述防误触算法可用于生成并加载上述防误触窗口，以达到防误触的效果。或者，上述防误触算法还可用于关闭手机屏幕的触控功能，以达到防误触的效果。或者，上述防误触算法还可用于将手机屏幕设置为锁屏状态或黑屏状态，使得手机屏幕无法响应接收到的任意操作，从而达到防误触 的效果。
