具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请一并参阅图1及图2，图1为本发明一实施例中的头戴式显示设备100的结构框图。如图1所示，所述头戴式显示设备100包括显示装置10、处理器20及传感器单元30。
所述显示装置10包括显示屏11及光学镜头12。所述显示屏11用于输出 包括指针的显示画面。所述光学镜头12位于所述显示画面的输出路径中。即，当用户穿戴头戴式显示设备100时，所述光学镜头12为位于显示屏11的靠近用户眼睛的一侧，从而显示屏11输出的显示画面将经过光学镜头12后才到用户的眼睛。
如图2所示，所述传感器单元30用于侦测所述光学镜头12与所述显示屏11之间的距离以得到一侦测距离D1。其中，所述传感器单元30设置于所述显示屏11和光学镜头12上。
所述处理器20用于至少根据所述传感器单元30侦测到的侦测距离D1调节所述指针移动的灵敏度。
在一些实施例中，所述处理器20至少根据所述传感器单元30侦测到的侦测距离调节指针灵敏度因子(factor)，以实现对所述指针移动的灵敏度的调节。其中，指针在显示屏11的移动距离等于输入装置200(如图4所示)的物理移动距离乘以指针灵敏度因子，在指针灵敏度因子改变时，指针的移动灵敏度也相应改变，从而通过调节指针灵敏度因子，可以实现对指针移动灵敏度的调节。
其中，所述光学镜头12可根据用户的操作移动，例如当用户对头戴式显示设备100的屈光度进行调节时该光学镜头12会移动到不同的位置，当光学镜头12的位置不同时，可以产生不同的矫正度数效果。因此，当近视用户等用户在使用头戴式显示设备100时，会调节光学镜头12的位置，此时，根据侦测到的光学镜头12与显示屏11的距离则可以自动调节指针移动的灵敏度，适合不同人的使用。
如图2所示，在一实施例中，所述处理器20获取所述显示屏11及所述显示装置10的出瞳位置C1之间的实际距离W1，并计算所述实际距离W1与所述侦测距离D1之间的差得到出瞳距Dc，然后计算所述出瞳距Dc与一第一预设距离J1的比值得出目标指针灵敏度因子，并将当前的指针灵敏度因子调节为所述目标指针灵敏度因子。即，所述目标指针灵敏度因子等于所述出瞳距Dc与所述第一预设距离J1的比值。其中，所述出瞳位置C1为用户穿戴所述头戴式显示设备100时，用户眼睛所在的位置。所述第一预设距离J1为光学镜头12处于初始位置时，光学镜头12与所述出瞳位置C1之间的距离。在一 些实施例中，所述出瞳位置C1处设置有目镜，所处出瞳位置C1可以为称为目镜。
即，在所述实施例中，所述处理器20根据公式Dc/J1计算得出所述目标指针灵敏度因子。其中，如前所述，Dc＝W1-D1，J1为所述第一预设距离。当光学镜头12处于初始位置时，所述光学镜头12不进行度数矫正，用户通过光学镜头12看到的显示画面为未进行视力矫正的正常的显示画面。
在另一实施例中，所述处理器20根据所述侦测距离D1确定所述光学镜头12在当前位置对人眼的矫正度数Y1，并根据所述侦测距离D1以及矫正度数Y1计算出通过光学镜头12看到的显示画面的缩放倍数，然后确定所述缩放倍数的倒数为目标指针灵敏度因子，并将当前的指针灵敏度因子调节为所述目标指针灵敏度因子。其中，侦测距离D1与矫正度数Y1之间有预设的对应关系，根据所述对应关系可以得出侦测距离D1对应的矫正度数Y1。所述预设的对应关系可以事先通过多次试验测试得出或者通过特定的关系式得出。
具体的，所述处理器20根据公式F1＝P1/P2＝(D1*Y1)*ppi*S1/d*Y2*ppi*S1计算的到缩放倍数F1，其中，D1为所述侦测距离，Y1为矫正度数，d为光学镜头处于初始位置时与所述显示屏11之间的距离。所述ppi为画面像素密度，S1为控制指针移动的输入装置200(如图4所示)的物理移动距离。Y2为正常屈光度，一般为1。
因此，所述缩放倍数F1＝P1/P2＝(D1*Y1)*ppi*S1/d*Y2*ppi*S1，可以简化为F1＝(D1*Y1)/d。
其中，P1＝(D1*Y1)*ppi*S1，为当光学镜头12与所述显示屏11的距离为D1时，输入装置200移动距离S1时，指针在显示画面中的移动距离。P2＝d*Y2*ppi*S1，为当光学镜头12与所述显示屏11的距离为初始距离d时，输入装置200移动距离S1时，指针在显示画面中的移动距离。
其中，P1/P2为输入装置200移动相同距离时，指针在缩放后的显示画面中的移动距离与在正常/初始显示画面中的移动距离的比值，就相当于显示画面的缩放倍数。放大倍数越大，则需要调低灵敏度因子，免得移动距离被放大过多而导致灵敏度过大的问题。
因此，缩放倍数与灵敏度成反比。所述处理器20确定所述缩放倍数的倒 数为目标指针灵敏度因子。从而，所述目标指针灵敏度因子＝d/(D1*Y1)。
其中，如图1所示，所述传感器单元30包括信号产生单元31及信号接收单元32。所述信号产生单元31及信号接收单元32中的一个设置于所述光学镜头12，所述信号产生单元31及信号接收单元32中的另一个设置于所述显示屏11，所述信号产生单元31用于产生特定信号，所述信号接收单元32用于接收所述特定信号，并根据接收到的特定信号确定所述光学镜头12与所述显示屏11之间的距离。
例如，在一些实施例中，所述信号产生单元31为红外发射器，用于发射红外信号，所述信号接收单元32为红外接收器，用于接收所述红外信号，并根据接收所述红外信号与所述红外发射器发射所述红外信号的时间间隔以及红外信号的速度确定所述光学镜头12与所述显示屏11之间的距离。
又例如，在一些实施例中，所述信号产生单元31为磁铁，所述信号接收单元32为磁力接收传感器，用于侦测或接收磁铁产生的磁力，并根据接收到的磁力的强度确定所述光学镜头12与所述显示屏11之间的距离。
如图1所示，所述显示装置10还包括一驱动单元13，所述驱动单元13与所述光学镜头12连接，用于响应用户操作驱动光学镜头12沿着所述显示画面的输出路径的方向移动，以增大或减小光学镜头12与显示屏11的距离。
其中，所述光学镜头12可安装于与用户视线平行/与显示画面输出路径平行的轴(图中未示)上并可在驱动单元13的驱动下沿该轴移动，从而靠近或远离用户的眼睛/出瞳位置C1运动(也即远离或靠近显示屏11运动)而进行调焦，而作为具有相应矫正度数的矫正镜片存在。
在本实施例中，所述光学镜头12为放大镜，例如凸透镜，所述光学镜头12响应所述驱动单元13的驱动而移动时使得显示屏11上的显示画面进入人眼的放大倍数改变从而改变矫正度数。
请一并参阅图3，其中，当光学镜头12被驱动运动而使得显示画面放大时，显示屏11输出显示画面后，经过光学透镜12后进入人眼中的画面为放大的虚像M1，人眼看到的效果为放大的显示效果。
请一并参阅图4，为头戴式显示设备100的整体结构示意图。所述头戴式显示设备100还与输入装置200连接。所述输入装置200用于控制指针进行移 动等输入控制。其中，所述输入装置200可为触摸板、鼠标、或者手机、平板电脑等的触摸屏。
所述处理器20根据所述传感器单元侦测到的侦测距离调节指针灵敏度因子，从而调节所述指针移动的灵敏度包括：在输入装置200控制指针移动时，将输入装置200的物理移动距离乘以所述指针灵敏度因子得到指针在显示画面上的移动距离，而控制目标指针在显示画面上移动相应的距离，而对所述指针移动的灵敏度进行了相应调节。从而，灵敏度的调节是说通过调节灵敏度因子实现的。
其中，所述输入装置200为鼠标时，所述物理移动距离为输入装置200本身的移动距离，当输入装置200为触摸板或触摸屏时，所述物理移动距离可为在输入装置200上进行触摸的手指、触摸笔等的移动距离。

其中，在一些实施例中，所述输入控制方法还包括步骤：响应用户操作而控制所述光学镜头12沿着显示屏11显示的显示画面的出光路径的方向移动。其中，所述步骤可以执行于所述步骤S501之前，当光学镜头12的位置移动时，通过传感器单元30侦测到的侦测距离D1也将相应变化。
请参阅图6，为步骤S503在一实施例中的子流程图。在一实施例中，所述步骤S503包括：
获取所述显示屏11及所述显示装置11的出瞳位置C1之间的实际距离W1(S5031)。
计算所述实际距离W1与所述侦测距离D1之间的差得到出瞳距Dc(S5032)。
计算所述出瞳距Dc与一第一预设距离J1的比值得出目标指针灵敏度因子(S5033)。其中，所述第一预设距离J1为光学镜头12处于初始位置时，光学镜头12与所述出瞳位置C1之间的距离。
将指针灵敏度因子调节为所述目标指针灵敏度因子，以实现对指针移动灵敏度的调节(S5034)。
请参阅图7，为步骤S503在另一实施例中的子流程图。在另一实施例中，所述步骤S503包括：
根据所述侦测距离D1确定所述光学镜头12在当前位置对人眼的矫正度 数Y1(S5051)。其中，侦测距离D1与矫正度数Y1之间有预设的对应关系，根据所述对应关系可以得出侦测距离D1对应的矫正度数Y1。
根据所述侦测距离D1以及矫正度数Y1计算出通过光学镜头12看到的显示画面的缩放倍数，确定所述缩放倍数的倒数为目标指针灵敏度因子(S5052)。具体的，根据公式F1＝(D1*Y1)/d计算缩放倍数F1，其中，D1为所述侦测距离，Y1为矫正度数，d为光学镜头处于初始位置时与所述显示屏11之间的距离。
将指针灵敏度因子调节为所述目标指针灵敏度因子，以实现对指针移动的灵敏度的调节(S5053)。
其中，如图1所示，所述头戴式显示设备100还包括存储器50，所述存储器50中存储有若干程序指令，所述处理器20调用执行所述若干程序指令后，执行如图5-7所示的任一方法来实现对指针灵敏度的自动调节。

从而，本发明的头戴式显示设备100及输入控制方法，可以在用户根据自己的屈光度对光学镜头12的位置进行调节时，对应调节指针灵敏度，从而可自动适应具有不同屈光度的各类人群。
以上所述是本发明的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
