具体实施方式
现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
图1为根据本发明焦点定位方法的一种实施方式的流程图。
根据图1所示，本发明焦点定位方法包括如下步骤：
步骤S110，上电开始后，判断是否检测到对应虚拟现实设备的眉间区 域的眉间操作，如是，则执行步骤S120，如否，则循环执行该步骤S110。
此处的虚拟现实设备的眉间区域即为虚拟现实设备的、对应用户眉间区域的部位，因此，该眉间操作可以是用户通过皱眉、抬眉等行为对虚拟现实设备的该部位进行的挤压操作。
因此，检测虚拟现实设备的眉间区域的眉间操作可以采用但不局限于以下实施例。
实施例1：
步骤S111a：获取安装在虚拟现实设备的眉间区域上的压力传感器输出的压力信号。
该压力传感器例如可以采用灵敏性较高的压电式压力传感器。
步骤S112b：根据该压力信号，判断当前压力值是否超过设定值，如是，则判定发生眉间操作。
该设定值可以根据实验数据确定，即大量测量用户佩戴虚拟现实设备时，通过以上眉间操作会对虚拟现实设备的眉间区域造成的压力，并根据测量得到的数据选取合适的设定值，以兼顾提供较好的易操作性、及较低的误触发率。
实施例2：
步骤S111b：获取安装在虚拟现实设备上的图像采集装置采集到的图像。
步骤S112b：提取图像中用户眉间区域(包括眼眉部位)的特征。
步骤S113b：将提取到的特征与存储在数据库中作为参考的眉间区域形状和/或相对位置进行比对，如果比对成功，则判定发生眉间操作。
或者，根据提取到的特征在连续多帧采集到的图像中的位置变化，判断是否发生设定的眉间操作，如果位置变化符合设定的眉间操作的动作过程，则判定发生眉间操作。
实施例3：
步骤S111c：获取安装在虚拟现实设备的眉间区域的距离传感器输出的接近信号。
步骤S112c：根据该接近信号，判断接近量是否超过设定量，如是， 则判定发生眉间操作。
该接近量例如可以是标准距离与当前距离之间的差值，该标准距离可以人为设置，也可以根据用户的选择通过距离传感器采集设定。
步骤S120，控制屏幕出现焦点。
步骤S130，在焦点存在期间，根据检测到的焦点位置调整操作调整焦点的位置，即在该步骤S130进行焦点位置的调整。
该焦点位置调整操作可以但不局限于是头部摆动操作或者眼球移动操作等。
以头部摆动操作为例，可以通过检测用户头部的上、下、左、右摆动对应地调整焦点在屏幕上的位置。该头部摆动操作可以根据惯性传感器等采集到的数据进行识别。
又以眼球移动操作为例，可以通过检测用户眼球的上、下、左、右移动对应地调整焦点在屏幕上的位置。该眼球移动操作可以根据图像采集装置采集到的图像进行识别。
步骤S140，在焦点存在期间，根据检测到的焦点位置确定操作执行点击动作，即在该步骤S140执行对焦点所在位置的界面元素的点击操作。
该焦点位置确定操作例如可以是点头操作、闭眼操作、连续两次眉间操作等，但是，对应各种功能的操作应该各不相同，以在系统内部进行区分。
其中，点头操作可以根据惯性传感器采集到的数据进行识别。闭眼操作可以根据图像采集装置采集到的图像进行识别。连续两次眉间操作可参照在步骤S110中的说明进行判断，只需增加对两次眉间操作的时间间隔是否满足连续操作对时间的定义即可。
图2是根据本发明焦点定位方法的另一种实施例的流程图。
根据图2所示，该实施例在图1所示实施例的基础上，增加了步骤S210至步骤S230。
在步骤S210中，根据检测到的眉间操作，控制屏幕出现焦点后，判断检测到的眉间操作是否消失，如是，则执行步骤S220，如否，循环执行步骤S210。
在该步骤S210中，判断检测到的眉间操作是否消失的具体实施例与步骤S110中检测虚拟现实设备的眉间区域的眉间操作的实施例相对应。
以上述实施例1中，根据压力信号检测眉间操作为例，判断检测到的眉间操作是否消失可进一步包括：
步骤S211a：获取安装在虚拟现实设备的眉间区域上的压力传感器输出的压力信号。
步骤S212b：根据该压力信号，判断当前压力值是否转变为小于设定值，如是，则判定检测到的眉间操作消失。
步骤S220，判断眉间操作的消失时间是否达到设定时间，如是，再执行步骤S230，以避免因误操作而错误地控制焦点消失，如否，则回到步骤S210进行眉间操作仍不存在的判断。
这说明，在该实施例中，用户需要保持眉间操作直至执行完步骤S140，否则，只要检测到的眉间操作消失达到设定时间，则当前操作结束，回到步骤S110进行眉间操作的检测。
步骤S230，控制焦点消失。
在该实施例中，如果将连续两次眉间操作作为焦点位置确定操作，则连续两次眉间操作的时间间隔应该被设定为小于上述设定时间。
在另外的实施例中，也可以设置为焦点出现后即保持存在状态，直至完成步骤S140，控制焦点消失。
在另外的实施例中，还可以设置为焦点出现后，如果一定时间内没有检测到焦点位置调整操作和/或焦点位置确定操作，则控制焦点消失。
图3是根据本发明焦点定位装置的一种实施例的方框原理图。
根据图3所示，该焦点定位装置包括用于检测对应虚拟现实设备的眉间区域的眉间操作的模块301；用于根据检测到的眉间操作、控制屏幕出现焦点的模块302；用于在焦点存在期间，根据焦点位置调整操作调整焦点的位置的模块303；以及，用于在焦点存在期间，根据焦点位置确定操作执行点击动作的模块304。
上述用于检测对应虚拟现实设备的眉间区域的眉间操作的模块301可以进一步包括：用于获取安装在眉间区域上的压力传感器输出的压力信号 的单元；以及，用于根据压力信号，判断当前压力值是否超过设定值，并在超过设定值时判定发生眉间操作的单元。
图4是根据本发明焦点定位装置的另一种实施例的方框原理图。
根据图4所示，在该实施例中，本发明焦点定位装置还包括：用于在检测到的眉间操作消失、且消失时间达到设定时间时，控制屏幕上的焦点消失的模块305。
在本发明焦点定位装置的一个具体实施例中，上述焦点位置确定操作可以为连续两次眉间操作，其中，连续两次眉间操作的时间间隔被设定为小于上述设定时间。
在本发明焦点定位装置的一个具体实施例中，上述焦点位置调整操作可以为头部摆动操作或者眼球移动操作。
本发明还提供了一种虚拟现实设备，该虚拟现实设备包括上述任一种焦点定位装置。另外该虚拟现实设备还应该包括以上说明的配合对应焦点定位装置使用的传感器。
图5是该虚拟现实设备在硬件配置上的一种实施例的方框原理图。
根据图5所示，该虚拟现实设备500包括存储器501和处理器502，存储器501用于存储指令，该指令用于控制处理器502执行所述本发明任一种所述的焦点定位方法。
该处理器例如可以是中央处理器CPU、微处理器MCU等。该存储器例如包括ROM(只读存储器)、RAM(随机存取存储器)、诸如硬盘的非易失性存储器等。
根据图5所示，该虚拟现实设备500还可以包括接口装置503、输入装置504、显示装置505、通信装置506、扬声器507、麦克风508等等。尽管在图5中示出了多个装置，但是，本发明虚拟现实设备500可以仅涉及其中的部分装置，例如，处理器501、存储器502等。

本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分相互参见即可，每个实施例重点说明的都是与其他实施例的不同之处，但本领域技术人员应当清楚的是，上述各实施例可以根据需要单独使用或者相互结合使用。另外，对于装置实施例而言，由于其是与方法实施例相对应，所以描述得比较简单，相关之处参见方法实施例的对应部分的说明即可。以上所描述的系统实施例仅仅是示意性的，其中作为分离部件说明的模块可以是或者也可以不是物理上分开的。
本发明可以是装置、方法和/或计算机程序产品。计算机程序产品可以包括计算机可读存储介质，其上载有用于使处理器实现本发明的各个方面的计算机可读程序指令。
计算机可读存储介质可以是可以保持和存储由指令执行设备使用的指令的有形设备。计算机可读存储介质例如可以是――但不限于――电存储设备、磁存储设备、光存储设备、电磁存储设备、半导体存储设备或者上述的任意合适的组合。计算机可读存储介质的更具体的例子(非穷举的列表)包括：便携式计算机盘、硬盘、随机存取存储器(RAM)、只读存储器(ROM)、可擦式可编程只读存储器(EPROM或闪存)、静态随机存取存储器(SRAM)、便携式压缩盘只读存储器(CD-ROM)、数字多功能盘(DVD)、记忆棒、软盘、机械编码设备、例如其上存储有指令的打孔卡或凹槽内凸起结构、以及上述的任意合适的组合。这里所使用的计算机可读存储介质不被解释为瞬时信号本身，诸如无线电波或者其他自由传播的电磁波、通过波导或其他传输媒介传播的电磁波(例如，通过光纤电缆的光脉冲)、或者通过电线传输的电信号。
这里所描述的计算机可读程序指令可以从计算机可读存储介质下载到各个计算/处理设备，或者通过网络、例如因特网、局域网、广域网和/或无线网下载到外部计算机或外部存储设备。网络可以包括铜传输电缆、光纤传输、无线传输、路由器、防火墙、交换机、网关计算机和/或边缘服 务器。每个计算/处理设备中的网络适配卡或者网络接口从网络接收计算机可读程序指令，并转发该计算机可读程序指令，以供存储在各个计算/处理设备中的计算机可读存储介质中。
用于执行本发明操作的计算机程序指令可以是汇编指令、指令集架构(ISA)指令、机器指令、机器相关指令、微代码、固件指令、状态设置数据、或者以一种或多种编程语言的任意组合编写的源代码或目标代码，所述编程语言包括面向对象的编程语言—诸如Smalltalk、C++等，以及常规的过程式编程语言—诸如“C”语言或类似的编程语言。计算机可读程序指令可以完全地在用户计算机上执行、部分地在用户计算机上执行、作为一个独立的软件包执行、部分在用户计算机上部分在远程计算机上执行、或者完全在远程计算机或服务器上执行。在涉及远程计算机的情形中，远程计算机可以通过任意种类的网络—包括局域网(LAN)或广域网(WAN)—连接到用户计算机，或者，可以连接到外部计算机(例如利用因特网服务提供商来通过因特网连接)。在一些实施例中，通过利用计算机可读程序指令的状态信息来个性化定制电子电路，例如可编程逻辑电路、现场可编程门阵列(FPGA)或可编程逻辑阵列(PLA)，该电子电路可以执行计算机可读程序指令，从而实现本发明的各个方面。
这里参照根据本发明实施例的方法、装置(系统)和计算机程序产品的流程图和/或框图描述了本发明的各个方面。应当理解，流程图和/或框图的每个方框以及流程图和/或框图中各方框的组合，都可以由计算机可读程序指令实现。
这些计算机可读程序指令可以提供给通用计算机、专用计算机或其它可编程数据处理装置的处理器，从而生产出一种机器，使得这些指令在通过计算机或其它可编程数据处理装置的处理器执行时，产生了实现流程图和/或框图中的一个或多个方框中规定的功能/动作的装置。也可以把这些计算机可读程序指令存储在计算机可读存储介质中，这些指令使得计算机、可编程数据处理装置和/或其他设备以特定方式工作，从而，存储有指令的计算机可读介质则包括一个制造品，其包括实现流程图和/或框图中的一个或多个方框中规定的功能/动作的各个方面的指令。
也可以把计算机可读程序指令加载到计算机、其它可编程数据处理装置、或其它设备上，使得在计算机、其它可编程数据处理装置或其它设备上执行一系列操作步骤，以产生计算机实现的过程，从而使得在计算机、其它可编程数据处理装置、或其它设备上执行的指令实现流程图和/或框图中的一个或多个方框中规定的功能/动作。
附图中的流程图和框图显示了根据本发明的多个实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段或指令的一部分，所述模块、程序段或指令的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个连续的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。也要注意的是，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或动作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。对于本领域技术人员来说公知的是，通过硬件方式实现、通过软件方式实现以及通过软件和硬件结合的方式实现都是等价的。
以上已经描述了本发明的各实施例，上述说明是示例性的，并非穷尽性的，并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的。本文中所用术语的选择，旨在最好地解释各实施例的原理、实际应用或对市场中的技术的技术改进，或者使本技术领域的其它普通技术人员能理解本文披露的各实施例。本发明的范围由所附权利要求来限定。
