Description

可穿戴设备的控制方法及电子设备
本申请要求于2021年04月08日提交中国国家知识产权局、申请号为202110379909.2、申请名称为“可穿戴设备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
本申请实施例涉及可穿戴设备领域，尤其涉及一种可穿戴设备的控制方法及电子设备。
背景技术
虚拟现实(Virtual Reality，VR)头盔设备中的光学成像模组一般由显示屏和光学镜片组构成，如图1所示，当设备正常使用时，显示屏(即屏幕)发出的光线经过光学镜片组折射后进入人眼，进而使得用户可以看到VR头盔中的屏幕显示的画面。
当虚拟现实头盔设备停止使用后，设备中的光学镜片会暴露在环境中。如图2所示，由于这类设备中的光学镜片组对光线具有汇聚的作用，部分环境光会通过光学镜片组的人眼侧进入光学成像模组中，经过镜片组后聚焦到显示屏幕上，导致屏幕上光线聚焦点的能量大量聚集，进而对屏幕造成损伤，影响虚拟现实头盔设备的显示效果，甚至可能导致屏幕损坏，而无法显示画面。
目前，为解决环境光聚焦，对屏幕造成损伤的问题，已有技术采用的方式为增加偏振器件。其中，增加偏振器件是利用偏振原理，该偏振器件的偏振方向与虚拟现实头盔设备中屏幕光线的偏振一致。以利用偏振器件只能透过单一偏振方向光线的特性，减弱进入虚拟现实头盔设备的环境光线，同时可以让屏幕发出的偏振光线通过，实现在不影响显示效果的情况下，降低聚焦在屏幕上环境光线的强度，从而起到防止虚拟现实头盔被晒伤的作用。
但是，偏振片对同偏振方向的光线透过率不超过90％。因此，使用偏振片将会降低虚拟现实头盔的显示亮度。并且，若偏振片的方向与屏幕光线的偏振方向不一致，会进一步降低显示亮度，因此该方案对组装精度的要求较高。
发明内容
为了解决上述技术问题，本申请提供一种可穿戴设备的控制方法及电子设备。在该方法中，电子设备可通过调节光学镜片组的屈光度，以增大环境光线经过镜片聚焦在可穿戴设备的屏幕上的光斑尺寸，从而将光线的能量分散，进而避免屏幕被晒伤。
第一方面，本申请实施例提供一种可穿戴设备的控制方法。该方法包括：获取可穿戴设备的佩戴状态；当可穿戴设备从佩戴状态变为未佩戴状态，将可穿戴设备的光学镜片组的第一屈光度调整为第二屈光度，其中，第二屈光度大于第一屈光度。
这样，电子设备可对可穿戴设备的佩戴状态进行检测，并在检测到可穿戴设备处于 未佩戴状态的情况下，增大可穿戴设备的光学镜片组的屈光度，以增大环境光线经过镜片聚焦在可穿戴设备的屏幕上的光斑尺寸，从而将光线的能量分散，进而避免屏幕被晒伤。
示例性的，电子设备可以是可穿戴设备，或者是可穿戴设备中的芯片。也可以是外接设备，例如和可穿戴设备连接的电脑、手机等设备，或设备的芯片。
示例性的，本申请实施例可以在不改变已有可穿戴设备的结构的前提下，实现本申请实施例中的防晒模式。
示例性的，通过自动检测佩戴状态，并对应调节屈光度，以实现自动防晒功能。
示例性的，光学镜片组可以包括一个或多个镜片。镜片可选地是球面镜片、非球面镜片或菲涅尔镜片等光学镜片。
示例性的，镜片可以是塑料的，也可以是玻璃的，本申请不做限定。
根据第一方面，方法还包括：获取可穿戴设备的佩戴状态；当可穿戴设备从未佩戴状态变为佩戴状态，将可穿戴设备的光学镜片组的第二屈光度调整为第一屈光度。
这样，电子设备可通过检测可穿戴设备的佩戴状态，当可穿戴设备从未佩戴状态恢复到佩戴状态时，可穿戴设备可将光学镜片组的屈光度自动恢复到变换前的数值。以使得用户重新佩戴可穿戴设备时，能够自动解除防晒模式，使得用户观测到屏幕显示的清晰的画面。
示例性的，第一屈光度可以是用户在使用过程中设置的，也可以是可穿戴设备出厂设置的。
根据第一方面，或者以上第一方面的任意一种实现方式，第二屈光度为光学镜片组可达到的屈光度最大值。
这样，电子设备可通过将可穿戴设备的屈光度调节为最大值，使得光线最大程度上分散到屏幕上，以避免屏幕被晒伤。

图5为本申请实施例提供的一种可穿戴设备的控制方法的流程示意图。请参照图5，具体包括：
S101，传感器检测可穿戴设备的佩戴状态。
示例性的，如上文所述，可穿戴设备中可包括接近光传感器。接近光传感器可选地包括发射单元、接收单元和计算单元，发射单元用于发射探测信号(如红外线接近光传感器中的发射单元可以发射探测红外线)、接收机单元用于接收经目标物反射的探测信号，计算单元计算发射单元发射信号至接收器接收到信号的时间差，并根据信号的传播速度来计算传感器距离目标物体的距离。相应的，接近光传感器可基于上述原理，检测用户是否佩戴可穿戴设备。
需要说明的是，本申请实施例中仅以红外线接近光传感器为例进行说明。在其他实施例中，也可以通过其它可以检测可穿戴设备的佩戴情况的传感器实现，例如超声波接 近光传感器和激光接近光传感器等。本申请不做限定。
示例性的，接近光传感器可选地周期性地进行探测，并基于当前周期接收到的探测信号，确定用户佩戴可穿戴设备。可选地，接近光传感器也可以是实时探测佩戴情况，本申请仅以周期性探测为例进行说明。一个示例中，接近光传感器在检测到用户佩戴可穿戴设备后，可向处理器发送用户佩戴指示，用于指示用户佩戴可穿戴设备。另一个示例中，接近光传感器在检测到用户佩戴可穿戴设备后，可以检测上一个周期可穿戴设备是否为被佩戴状态，可选地，若上一个周期可穿戴设备为被佩戴状态，接近光传感器无需发送任何指示。若上一个周期可穿戴设备为未被佩戴状态，接近光传感器向处理器发送用户佩戴指示。也就是说，接近光传感器可以在可穿戴设备从未穿戴状态变为被佩戴状态，才向处理器发送用户佩戴指示信息，从而减少传感器与处理器之间的交互次数。
示例性的，若接近光传感器基于当前周期接收到的探测信号，确定用户未佩戴可穿戴设备。一个示例中，接近光传感器可向处理器发送用户未佩戴指示信息，用于指示用户未佩戴可穿戴设备，即执行S102。另一个示例中，接近光传感器也可以检测上一个周期可穿戴设备是否为被佩戴状态。可选地，若上一个周期可穿戴设备为未佩戴状态，接近光传感器无需发送任何指示。若上一个周期可穿戴设备为佩戴状态，接近光传感器可向处理器发送用户未佩戴指示。也就是说，接近光传感器可以在可穿戴设备从佩戴状态变为未佩戴状态，才向处理器发送用户未佩戴指示信息，可用于减少传感器与处理器之间的交互次数。
S102，传感器向处理器发送用户未佩戴指示。
具体描述参照上文，此处不再赘述。
S103，处理器记录调焦模块的当前状态。
示例性的，图6为示例性示出的可穿戴设备的结构示意图。请参照图6，如上文所述，调焦模块可选地包括电机(图中未示出)、齿轮601以及调节连杆602。
下面简单介绍调焦模块的调节原理。本申请实施例中的电机可选地为步进电机或伺服电机。电机通过接收电机驱动器的数字控制信号，控制齿轮601实现特定的角位移，其中，步进电机由数字控制信号的脉冲个数和频率来控制，伺服电机通过数字控制信号的脉冲时间长短来控制。在本申请实施例中，处理器在记录调焦模块的当前状态时，以图6为例，齿轮601当前位于调节连接杆602的位置a。在本申请实施例中，可以认为电机的位置即为齿轮601的位置。当然，电机也可以是与齿轮601分离的，即，电机与齿轮601的位置不相同，本申请不做限定。在本申请实施例中，处理器只需要记录电机所在位置对应的数字控制信号即可。在后续需要恢复时，处理器可基于记录的控制信号，控制电机将调焦模块恢复到当前的状态。
示例性的，调节连杆602的一端连接光学镜片组中的至少一个光学镜片，例如连接光学镜片604。电机基于处理器输出的控制信号，控制齿轮601在调节连接杆602上移动，可使得调节连杆602与齿轮601相对运动。调节连杆602移动，可使得光学镜片604移动，以调节光学镜片604与光学镜片603之间的水平方向的间距，从而实现光学镜片组屈光度的调节。
请继续参照图6，示例性的，用户当前佩戴可穿戴设备(例如VR头盔或VR眼镜)。 相应的，接近光传感器可检测到用户佩戴可穿戴设备，并向处理器发送用户佩戴指示。处理器响应于接收到的用户佩戴指示，记录当前电机所处位置。如图6所示，假设电机所处位置即为齿轮601对应的位置，齿轮601位于调节连杆602的位置a处。相应的，光学镜片604与光学镜片603之间的间距为间距a。在当前状态下，光线透过光学镜片组聚焦在屏幕605上，形成光斑a。需要说明的是，本申请实施例中，处理器记录的电机(或齿轮)的位置，也可以理解为齿轮与调节连杆之间的相对位置。一般情况下，齿轮的绝对位置是不变的，其锯齿转动可带动调节连杆之间的相对位置变换。
S104，处理器控制调焦模块调节到最大屈光度状态。
示例性的，处理器可预先配置最大屈光度状态，可选地，最大屈光度状态可以理解为光学镜片组的屈光度为可以达到的最大值时，调焦模块对应的状态。可以理解为，处理器预先配置有指定位置，当齿轮转动，使得齿轮置于调节连杆上的指定位置时，光学镜片组的屈光度为最大值，此时，调焦模块的状态即为最大屈光度状态。
举例说明，图7为示例性示出的调焦模块的位置变换示意图。请参照图7，示例性的，处理器可获取到调焦模块的当前状态，即，齿轮601在调节连杆602的位置a上。处理器还可以获取到预先配置的指定位置，例如图7中所示的位置b，即，处理器预先配置有指定位置，即位置b，期望通过齿轮601转动，改变齿轮601与调节连杆602之间的相对位置，以使得齿轮601处于调节连杆602的位置b上。处理器可基于调节模块的当前状态，以及预先配置的指定位置，获取到两个位置a与位置b之间的位移。处理器可通过控制信号，控制齿轮601转动，以使得调节连杆横向移动，以改变齿轮601与调节连杆之间的相对位置，直至达到位置b。处理器可记录改变的位移，以及对应的脉冲信号的个数，以用于后续的恢复过程。
仍参照图7，示例性的，调节连杆602横向移动，使得与其连接的光学镜片604同样横向移动。由于光学镜片603的位置保持不变，使得光学镜片604与光学镜片603之间的间距增大。当齿轮601位于调节连杆602的位置b时，光学镜片604与光学镜片603之间的间距为间距b。其中，间距b大于间距a。此时，光学镜片组的屈光度增加。相应的，环境光线透过光学镜片组折射到屏幕605上，由于屈光度增加，其在屏幕605上形成的光斑b。光斑b大于光斑a。可以理解为，本申请实施例中通过调节光学镜片组中的光学镜片之间的相对位置，以改变光学镜片组的屈光度。光学镜片组的屈光度增大后，使得环境光线无法聚焦在屏幕上，从而达到防晒的作用。
需要说明的是，本申请实施例中，例如图7所示的通过调节连杆调节光学镜片组中的镜片相对位置的方式仅为示意性举例。在其他实施例中，也可以通过其它可行的方式以调节光学镜片组中的光学镜片的相对位置，从而增加光学镜片组的屈光度，实现防晒目的。
进一步需要说明的是，本申请实施例中所述的指定位置仅为示意性举例。基于不同的光学镜片组的特性，其不同的屈光度对应的相对位置可以不相同。举例说明，厂家A生成的光学镜片组，当齿轮601位于调节连杆602的最左侧时，光学镜片组的屈光度最大，即，齿轮601位于调节连杆602最左侧时的位置，即为预设的指定位置，对应于调焦模块的最大屈光度状态。厂家B生成的光学镜片组，当齿轮601位于调节连杆602的 最右侧时，光学镜片组的屈光度最大，即，齿轮601位于调节连杆602的最右侧时的位置，即为预设的指定位置，对应于调焦模块的最大屈光度状态。因此，指定位置可根据实际需求设置，本申请不做限定。
进一步需要说明的是，本申请实施例中仅以将屈光度调节到最大程度为例进行说明。在其他实施例中，例如，齿轮601位于调节连杆602的最左侧时，光学镜片组的屈光度最大，调焦模块为最大屈光度状态。而当齿轮601在调节连杆602上的位置接近最左侧时，其屈光度即可使得环境光学无法聚焦在屏幕上，相应的，为提高后续的恢复效率，非最大屈光度对应的位置，同样可作为指定位置，本申请不做限定。
在一种可能的实现方式中，处理器在接收到未佩戴指示后，启动计时器。计时器的计时时长可根据实际需求设置，例如可以是1分钟，本申请不做限定。计时器计时结束后，处理器未接收到用户佩戴指示，则处理器可确定设备停用。处理器可执行S103及后续步骤。从而可避免因用户短时间的启停设备导致的防晒模式频繁的开启与关闭。
在另一种可能的实现方式中，处理器在接收到未佩戴指示后，即可执行S103及后续的步骤，即，开启防晒模式。
S105，传感器向处理器发送用户佩戴指示。
示例性的，如上文所述，传感器可选地为实时或周期性地检测可穿戴设备的佩戴情况。也就是说，在上述各步骤执行的过程中，传感器持续检测可穿戴设备的佩戴情况。
示例性的，在本申请实施例中，传感器检测到用户佩戴可穿戴设备后，可向处理器发送用户佩戴指示，用于指示用户佩戴可穿戴设备。具体描述可参照S101中的相关内容，此处不再赘述。
S106，处理器控制调焦模块恢复到之前的状态。
示例性的，如上文所述，处理器控制调焦模块的状态变换前，已记录有调焦模块变换前的状态(即S103中所记录的状态)。处理器可基于调焦模块最大屈光度状态以及变换前状态，将调焦模块恢复到变换前状态。
举例说明，图8为示例性示出的调焦模块的位置变换示意图，以示出调焦模块的恢复过程。请参照图8，示例性的，如上文所述，处理器记录有之前将齿轮601从调节连杆的位置a移动到位置b对应的脉冲信号个数。相应的，处理器可基于记录的脉冲信号个数，控制电机带动齿轮601转动，以使得齿轮601从调节连杆上的位置b恢复到位置a。相应的，光学镜片604随着调节连杆移动，光学镜片604与光学镜片603之间的间距，从间距b恢复到间距a，以恢复光学镜片组的屈光度。从而使得环境光线通过光学镜片组，在屏幕605上聚焦，形成光斑a。
可选地，图5中所示的可穿戴控制方法是基于可穿戴设备中的传感器对佩戴状态进行检测的基础上实现的。在其他实施例中，若可穿戴设备中不包括可以检测佩戴状态的传感器，例如不包括接近光传感器。在该场景下，防晒模式的触发条件可以是基于可穿戴设备的开关状态。举例说明，可穿戴设备可设置有开关，用于开启和关闭可穿戴设备。示例性的，处理器检测到可穿戴设备的开关关闭，即可穿戴设备从开启状态变为关闭状态，处理器可执行上述S103和S104，即记录调焦模块的当前状态，并将调焦模块置于指定位置。示例性的，当处理器检测到可穿戴的开关开启，即可穿戴设备从关闭状态变 为开启状态，处理器可执行上述S106，即控制调焦模块恢复到关机前的状态。也就是说，在本申请实施例中，可通过检测用户的开机和关机操作，以触发防晒模式的开启和关闭。
可以理解的是，电子设备为了实现上述功能，其包含了执行各个功能相应的硬件和/或软件模块。结合本文中所公开的实施例描述的各示例的算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以结合实施例对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

装置900的各个组件通过总线904耦合在一起，其中总线904除包括数据总线之外，还包括电源总线、控制总线和状态信号总线。但是为了清楚说明起见，在图中将各种总线都称为总线904。
