Description

头戴式显示设备及屈光度自适应调节方法 技术领域
本发明涉及一种显示设备,尤其涉及一种头戴式显示设备及所述头戴式显示设备根据用户的屈光度自动进行适应性调节的方法。
背景技术
头戴式显示设备由于便捷性,且能实现立体显示及立体声等效果,已经逐渐被人们所喜爱。然而,头戴式显示设备的用户的眼睛视力有好有坏,为了满足有近视眼或远视眼的用户的需要,现有的头戴显示设备都要求能够对用户的视力进行矫正。目前,针对近视眼或远视眼的处理方式有两种:第一种是兼容配戴校正眼镜后再配戴所述头戴式显示设备,然而,此种方法的缺点是佩戴时会有压迫感,导致不舒适。第二种是根据感官连续调节或通过档位调节来手动调节屈光度。其中,通过感官进行连续调节,非专业人士很难准确调整至匹配自己的屈光度。通过档位来进行调节,由于档位的数量有限,用户只能根据屈光度来调到大致相近的档位,往往很难细调到非常符合自己屈光度的档位。从而,目前通过感官或档位来调节屈光度的方式,由于矫正很难准确,往往会导致长时间配戴设备对眼睛造成损伤。
发明内容

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。
请参阅图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包括显示模组10、输入模组20、屈光度调节模组30及处理器40。
所述显示模组30用于通过第一预设光路及第二预设光路分别输出显示画面至目镜C1/C2(如图3所示)。其中,所述目镜C1/C2指的是当用户穿戴所述头戴式显示设备100时用户眼睛观看的镜头。其中,所述通过第一预设光路及第二预设光路输出的显示画面分别传送到用户的左右眼。所述屈光度调节模组30用于对第一预设光路和/或第二预设光路的焦距进行调节。所述输入模组20用于响应用户的输入而产生输入信息。
请一并参阅图2,所述处理器40用于响应一屈光度矫正信号,控制所述显示模组10通过第一预设光路输出包括有视力表T1的显示画面P1,所述头戴式显示设备100并根据输入模组20产生的输入信息判断接收第一预设光路输出的显示画面P1的眼睛(如左眼)的验光是否完成,并在确定接收第一预设光路输出的显示画面P1的眼睛的验光完成时,控制所述显示模组10通过第 二预设光路输出包括有视力表T1的显示画面P1。所述头戴式显示设备100并根据输入模组20的输入判断接收第二预设光路输出的显示画面P1的另一眼睛(如右眼)的验光是否完成,并在确定所述另一眼睛的验光完成时确定左右眼验光均完成。
所述处理器40并在确定左右眼验光均完成时,根据左右眼验光得出的屈光度控制所述屈光度调节模组30对第一预设光路和/或第二预设光路的焦距进行调节,以对左眼和/或右眼的屈光度进行矫正。其中,所述处理器40控制所述屈光度调节模组30对第一预设光路和/或第二预设光路的焦距进行调节时,当调节到使得用户的屈光度矫正到预设范围时停止调节。例如,所述处理器40控制屈光度调节模组30进行焦距调节后使得左右眼的屈光度矫正在视力为1.0以上时,则控制屈光度调节模组30停止进行调节。
在一些实施例中,所述处理器40还根据左右眼验光得出的屈光度判断是否需要对左眼和/或右眼的屈光度进行矫正,并在判断需要对用户的左眼和/或右眼的屈光度进行矫正时,根据左右眼验光得出的屈光度控制所述屈光度调节模组30对第一预设光路和/或第二预设光路的焦距进行调节。
其中,所述屈光度矫正信号可为用户操作特定按键、特定菜单选项等产生。
如图2所示,所述视力表T1可为通常的视力检测表,包括多行方向标识符F1,每一行方向标识符F1包括多个用于指示不同方向的方向标识符F1,且所述多行方向标识符F1的大小由上往下依序逐行减小,每一行方向标识符F1对应一屈光度。其中,所述方向标识符F1可为如图2所示的“山”字,所述多行方向标识符F1的大小从上到下逐行减小。所述视力表T1中的方向标识符F1根据第一预设光路和/或第二预设光路的长度以及现实中视力检测表中方向标识符F1的大小及检测距离进行相应的缩放,以与现实中视力检测表的使用完全一致。其中,所述第一预设光路和/或第二预设光路的长度为显示模组10发出的光自所述显示模组10起经过所述第一预设光路和/或第二预设光路到达人眼所经过的路线的实际长度。因此,通过用户是否可准确识别视力表T1的方向标识符F1来检查用户的屈光度与用户在现实中观察视力检测表是完全一样的效果。如前所述,与现实中的视力检测表一样,所述视力表T1的每一行的方向识别字F1对应一个级别的屈光度。
所述输入信息为方向信息,所述输入模组20用于供用户输入而产生方向信息。所述头戴式显示设备100并根据输入模组20产生的输入信息确定接收第一预设光路或第二预设光路输出的显示画面的眼睛的验光是否完成包括:所述处理器40控制显示模组10将第一预设光路或第二预设光路当前输出的显示画面中的视力表T1中的其中的一个方向标示字F1突出显示,并在判断输入模组20当前产生的方向信息与所述方向标示字F1所标识的方向一致时,确定对该方向标示字F1识别正确,并突出显示具有更小字体的下一行方向标示字F1中的其中一个方向标示字F1,然后继续判断输入模组20当前产生的方向信息与所述突出显示的方向标示字F1的朝向是否一致。所述处理器40在判断输入模组20当前产生的方向信息与所述突出显示的方向标示字F1的朝向不一致时,确认上一行的方向标示字F1对应的屈光度为该用户对应眼睛的屈光度。
在一些实施例中,所述处理器40将所述方向标识符F1突出显示可为在方向标识符F1的周围增加环绕所述方向标识符F1的圆圈、三角形等标记。在另一些实施例中,所述处理器40将所述方向标识符F1突出显示可为改变所述方向标识符F1的颜色等。在其他实施例中,所述处理器40将所述方向标识符F1突出显示可同时包括增加环绕所述方向标识符F1的标记以及改变所述方向标识符F1的颜色等。
在一些实施例中,如图1所示,所述输入模组20包括动作传感器21,所述动作传感器21用于侦测用户的手势并根据所述手势的运动方向产生所述方向信息,即所述方向信息包括所述手势的运动方向。所述处理器40判断所述动作传感器21当前感测到的手势的运动方向与所述突出显示的方向标示字F1所标识的方向是否一致,以进行视力检测。
在另一些实施例中,如图2所示,所述输入模组20还可包括声音传感器22,所述声音传感器22用于侦测用户的语音并根据所述侦测的语音产生所述方向信息,即所述方向信息包括所述侦测到的语音中的方向。例如,当处理器控制显示模组10将当前输出的显示画面中的视力表T1中的其中的一个方向标示字F1突出显示时,用户可根据自己观察的方向说“上”、“下”、“左”、“右”等。所述处理器40判断所述声音传感器22当前根据侦测的语音所产生的方向信息与所述突出显示的方向标示字F1的方向是否一致,以进行视力检 测。
显然,在其他实施例中,所述输入模组20还可为其他的输入设备,本申请所举例的动作传感器21及声音传感器22仅仅为示例。例如,在其他实施例中,所述输入模组20还可为摄像头,通过捕捉用户的手势动作确定方向信息。

所述处理器40根据左右眼验光得出的屈光度判断是否需要对左眼或右眼的屈光度进行矫正,并在判断需要对用户的左眼的屈光度进行矫正时,控制第一调节单元31的驱动元件311去驱动第一调节单元31的凹透镜312或凸透镜313作用于所述第一预设光路L1,例如位于用户的左眼的正前方。所述处理器 40并根据所述验光得出的屈光度控制凹透镜312或凸透镜313进行调焦,例如靠近或远离用户眼睛移动,直到移动到与所述左眼的屈光度对应的目标位置。
相应的,所述处理器40在判断需要对用户的右眼的屈光度进行矫正时,控制第二调节单元32的驱动元件311去驱动第二调节单元32的凹透镜312或凸透镜313作用于所述第二预设光路L2,例如位于用户的左眼的正前方。所述处理器40并根据所述验光得出的屈光度控制第二调节单元32的驱动元件311驱动第二调节单元32的凹透镜312或凸透镜313进行调焦,例如控制第二调节单元32的驱动元件311驱动第二调节单元32的凹透镜312或凸透镜靠近或远离用户眼睛移动,直到移动到与所述右眼的屈光度对应的目标位置。
在一些实施例中,所述头戴式显示设备100还包括存储器50,所述存储器50中还存储有屈光度与凹透镜312或凸透镜313所处位置的对应关系。所述处理器40根据所述屈光度与凹透镜312或凸透镜313所处位置的对应关系确定当前屈光度对应的所述凹透镜312或凸透镜313所处位置,并控制所述对应的凹透镜312或凸透镜313移动到对应的位置。显然,第一调节单元31与第二调节单元32的结构相同,调节原理相同,所述屈光度与凹透镜312或凸透镜313所处位置的对应关系同时适用于所述第一调节单元31与第二调节单元32的调节。显然,在一些实施例中,所述存储器50中还可存储视力表T1中各行与屈光度的对应关系。
其中,所述处理器40在判断用户的左眼或右眼为近视眼时,为控制对应的驱动元件311驱动对应的凹透镜312旋转至位于用户左眼或右眼的正前方,并控制对应的驱动元件311驱动对应的凹透镜312相对用户的左眼或右眼移动到与所述验光得出的屈光度对应的目标位置。
