实施本发明的方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
虚拟现实(Virtual Reality，缩写为VR)，是一种可以创建和体验虚拟世界的计算机仿真技术。虚拟现实的终端设备可以通过计算机技术模拟产生一个三维空间的虚拟世界，提供用户关于视觉等感官的模拟，让用户感觉仿佛身历其境。在一些应用场景中，虚拟现实的终端设备包括显示设备和成像设备。例如，成像设备包括透镜(通常包括一个或两个透镜，但不限于此)。显示设备包括与透镜相对设置的显示屏。这样，用户可以通过透镜观看显示设备上显示的图像，以便感知相应的虚拟成像。这里，显示设备可以被实现为集成在虚拟现 实的终端设备上，也可以被实现为可拆卸的移动设备(例如为移动电话、掌上电脑等计算设备。)
图1示出了根据本申请一些实施例的虚拟现实的终端设备的结构示意图。图2示出了图1中终端设备上相对设置的透镜和显示屏的示意图。图3示出了图1中终端设备的剖面示意图。
如图1所示，虚拟现实的终端设备包括显示设备1、与显示设备1相对设置的成像设备2和支撑件3。支撑件3适于支撑显示设备1和成像设备2。如图2所示，显示设备1例如可以包括显示屏11。成像设备2例如可以包括透镜21。这里，透镜21例如为非球面镜或者菲涅尔透镜等等。支撑件3也可以被认为是终端设备的外壳。这里，虚拟现实的终端设备可以被实现为虚拟现实头盔(head-mounted display,缩写：HMD)、虚拟现实眼镜(Virtual reality glass，缩写：VRG)等各种具体头戴式虚拟现实设备(Virtual reality headset，缩写：VRH)，本申请对此不做限制。从功能角度而言，虚拟现实的终端设备可以由用户单眼或双眼观看。换言之，虚拟现实的终端设备可以被实现为单目设备(例如单目虚拟现实眼镜等)或者双目设备(例如双目虚拟现实眼镜等)。在一些实施例中，图1所示结构可以被实现为一个单目设备。在又一些实施例中，本申请的终端设备可以被实现为双目设备。图1所示的结构为双目设备的一部分。在被实现为双目设备时，终端设备通常可以包括两个透镜21和两个显示屏11。每个透镜21对应一个显示屏11。两个显示屏21可以显示不同的图像。在此基础上，用户可以通过这两个显示屏观看到三维立体图像。另外，终端设备也可以被配置为包括两个透镜21和一个显示屏11。通过两个透镜，用户可以分别看到不同的图像(例如，用户通过一个透镜看到显示屏所显示的奇数帧图像，通过另一个透镜看到显示屏所显示的偶数帧图像)。
图3示出了图1中虚拟现实的终端设备的剖面示意图。如图3所示，虚拟现实的终端设备还包括设置在支撑件3上的除尘器件31。在显示设备1和/或成像设备2附着有异物(例如灰尘或水珠等等)时，除尘器件31可以使得异物相 对于其所附着的设备运动，以便异物脱离所附着的设备。这里，异物例如是终端设备组装过程中附带的污染物、使用终端设备过程中设备内部损坏产生的细微颗粒或者是温度变化时设备内部凝结的水珠等等。
下面结合图4对除尘器件31进一步说明。图4示出了图1中虚拟现实的终端设备的成像示意图。如图4所示，从P位置处通过透镜21观看显示屏11时，用户看到的虚像位于平面区域V。图4示例性示出了一个异物(灰尘或水珠)占据的区域S1。区域S1的异物可以阻碍显示屏11上一个或多个像素显示单元(每个像素显示单元可以通过红、绿和蓝(RGB)三种显示颜色混合为该显示单元的显示颜色)。区域S1的异物可以被放大显示在用户所看到的虚像上。平面区域V中区域S2为区域S1的异物被放大显示时所占据的区域。显然，由于异物将会被放大显示，显示设备1上异物可以极大影响虚拟成像效果。例如，异物可以使得虚拟成像上出现黑点、暗斑或局部模糊等现象。相应地，除尘器件31通过清除位于显示设备1或者成像设备2上的异物，可以避免异物对虚拟成像效果的影像，从而极大提高用户体验度。
在一个实施例中，除尘器件31可以被配置为振动器件。振动器件例如包括一个微型马达(未示出)和设置在微型马达的转轴上的偏心轮(未示出)，但不限于此。这里，振动器件可以带动显示设备1和成像设备2振动。这样，异物可以相对于所附着的设备(即，显示设备1或成像设备2)运动。这里，异物的运动过程使得异物的表面吸附力降低，摩擦力也降低，以便异物脱离所附着的设备。在又一个实施例中，除尘器件31可以被配置为超声波器件。超声波器件可以发出超声波(即频率高于20000赫兹的声波，方向性好，穿透能力强，易于获得较集中的声能)，使得显示设备1与成像设备2之间的空气振动，从而带动异物振动，进而使得异物最终离开所附着的设备。需要说明的是，除尘器件31可以包括一种或多种工作模式。除尘器件31可以在每种工作模式下按照相应的振动参数进行振动。这里，振动参数包括振动频率、振动幅度和振动方向。
在一些实施例中，本申请的虚拟现实的终端装置还可以包括与除尘器件31 耦接的控制器(未示出)。控制器可以控制除尘器件的工作状态。在一个实施例中，控制器可以根据在用户在终端设备上所输入的模式选择操作(例如为按钮操作或者触摸屏输入)，确定该模式选择操作所对应的预定工作模式。这里，预定工作模式的参数包括除尘器件31的预定振动频率、预定振动幅度和预定振动方向。控制器还可以生成与预定工作模式对应的除尘指示，并驱动除尘器件按照所生成的除尘指示工作。在又一个实施例中，控制器可以响应于对除尘的按钮操作，生成相应的除尘指示。基于除尘指示，控制器可以驱动除尘器件31分别在多个时间段的每个时间段内，按照该时间段对应的工作模式进行工作。这里，多个时间段既可以是连续的，也可以是离散的，本申请对此不作限制。其中，每个时间段对应的工作模式是指：按照该时间段对应的振动参数进行振动。在又一个实施例中，在虚拟现实的终端设备进入激活状态(例如，从休眠状态唤醒或进入开机状态等)时，控制器可以控制除尘器件31可以分别在多个时间段的每个时间段内，按照该时间段对应的工作模式进行工作。在上述实施例中，通过在每个时间段按照相应的工作模式进行振动(通常不同时段的工作模式不同)，除尘器件可以使得异物与附着的设备在不同时间段内进行不同的相对运动，从而可以极大提高异物被清除的可能性。另外说明的是，控制器可以由逻辑门、开关、专用集成电路(ASIC)、可编程逻辑控制器和嵌微控制器等来实现，也可以被实现为由终端设备的处理器(CPU)执行的应用，本申请对此不做限制。
在一些实施例中，显示屏11的表面可以设置疏水性镀膜，透镜21的表面也可以设置疏水性镀膜。这里，疏水性镀膜可以降低表面能。这样，疏水性镀膜可以使得显示屏11和透镜21表面的异物(特别是水珠)更容易被移动，从而使得异物更容易被清除。
在一些实施例中，虚拟现实的终端设备还可以在显示屏11和透镜21各自的边缘处设置吸附材料。这里，吸附材料适于吸附异物，例如为泡棉材质等等。图5示出了图3中A处放大示意图。图6示出了图3中B处放大示意图。如图5 及图6所示，终端设备可以在显示屏11的至少一部分边缘处设置第一吸附件4，在透镜21的至少一部分边缘处设置第二吸附件5。这里，第一和第二吸附件可以吸附异物，以避免异物再次污染显示屏11或透镜21。
图7示出了根据本申请一些实施例的除尘方法700的流程图。这里，除尘方法700适于在根据本申请的虚拟现实的终端设备中执行。例如，方法700可以在上述与除尘器件31耦接的控制器中执行。又例如，方法700可以在终端设备的一个除尘应用或组件中执行。总体而言，除尘方法700可以根据除尘指示驱动除尘器件按照除尘指示工作。具体而言，方法700包括步骤S701和S702。在步骤S701中，根据在所述终端设备上所输入的模式选择操作(例如为触摸屏输入或者通过物理按钮的输入)，确定该模式选择操作所对应的预定工作模式。预定工作模式的参数包括除尘器件的预定振动频率、预定振动幅度和预定振动方向。在步骤S702中，生成与预定工作模式对应的除尘指示，并驱动除尘器件按照所生成的除尘指示工作。
图8示出了根据本申请一些实施例的除尘方法800的流程图。除尘方法800适于在根据本申请的虚拟现实的终端设备中执行。例如，方法800可以在上述与除尘器件31耦接的控制器中执行。又例如，方法800可以在终端设备的一个除尘应用或组件中执行。总体而言，除尘方法800可以根据除尘指示驱动除尘器件按照除尘指示工作。具体而言，方法800包括步骤S801和S802。在步骤S801中，响应于对除尘的按钮操作(例如，终端设备上配置为相应的物理操作按钮)，生成相应的除尘指示。在步骤S802中，根据除尘指示，驱动除尘器件分别在多个时间段的每个时间段内，按照该时间段对应的工作模式进行工作。其中，每个时间段对应的工作模式包括按照该时间段对应的振动参数进行振动。
图9示出了根据本申请一些实施例的终端设备的结构图。如图9所示，该终端设备包括一个或者多个处理器(CPU)902、通信模块904、存储器906、用户接口910、除尘器件920，以及用于互联这些组件的通信总线908。这里，终端设备可以被实现为虚拟现实头盔、虚拟现实眼镜等等头戴式虚拟现实设备 (Virtual reality headset，缩写：VRH)。
处理器902可通过通信模块904接收和发送数据以实现网络通信和/或本地通信。
用户接口910包括一个或多个输出设备912，其包括一个或多个扬声器和/或一个或多个可视化显示器。用户接口910也包括一个或多个输入设备914。用户接口910例如可以接收遥控器的指令，但不限于此。
存储器906可以是高速随机存取存储器，诸如DRAM、SRAM、DDR RAM、或其他随机存取固态存储设备；或者非易失性存储器，诸如一个或多个磁盘存储设备、光盘存储设备、闪存设备，或其他非易失性固态存储设备。
存储器906存储处理器902可执行的指令集，包括：
操作系统916，包括用于处理各种基本系统服务和用于执行硬件相关任务的程序；
应用918，包括用于实现上述方法的各种程序，这种程序能够实现上述各实例中的处理流程。例如，应用918可以包括控制器922。控制器922可以执行图7所示的除尘方法700或者图8所示的除尘方法800。
除尘器件920可以根据指示执行除尘工作。另外，本申请的每一个实例可以通过由数据处理设备如计算机执行的数据处理程序来实现。显然，数据处理程序构成了本申请。此外，通常存储在一个存储介质中的数据处理程序通过直接将程序读取出存储介质或者通过将程序安装或复制到数据处理设备的存储设备(如硬盘和/或内存)中执行。因此，这样的存储介质也构成了本申请。存储介质可以使用任何类型的记录方式，例如纸张存储介质(如纸带等)、磁存储介质(如软盘、硬盘、闪存等)、光存储介质(如CD-ROM等)、磁光存储介质(如MO等)等。
因此本申请还公开了一种非易失性存储介质，其中存储有数据处理程序，该数据处理程序用于执行本申请上述方法的任何一种实例。
另外，本申请所述的方法步骤除了可以用数据处理程序来实现，还可以由 硬件来实现，例如，可以由逻辑门、开关、专用集成电路(ASIC)、可编程逻辑控制器和嵌微控制器等来实现。因此这种可以实现本申请所述方法的硬件也可以构成本申请。在一些实例中，本申请的终端设备还可以包括与除尘器件920耦接的控制器924。这里，控制器924被实现为硬件模块，控制器924例如可以接收一个输入设备914(例如物理按钮、遥控器或者触摸屏等等)的除尘指示，并根据除尘指示执行图7示出的除尘方法700或者图8示出的除尘方法800。这里，本申请的终端设备可以通过控制器922或者控制器924控制除尘器件。
以上所述仅为本申请的较佳实例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
