本发明涉及视力矫正领域，具体涉及一种基于VR技术的弱视训练复健系统及方法。
背景技术
大约5000人就会有1人，而现今社会发展下，近距离用眼的机会较过去多，不正确的写字阅读姿势，因此，两眼视差就愈来越严重。
而少部分的人在幼儿时期会因为眼球的先天性眼球屈光条件不佳而产生弱视眼，且该具有弱视眼的幼儿大都伴随着有融像困难的现象，所以在这种不利视觉发展条件下，具有弱视眼的幼儿在成长过程中的视欲能力大都是以另一只优视眼来使用，而另一只弱视眼则经常被放弃使用。
当幼儿在发展过程中，一旦发现具有弱视眼时，目前的作法大都是通过配戴眼镜的方式来进行矫正，但是对幼儿来说，因为视差的关系所以常常会有戴不住眼镜的现象，而使治疗效果变得毫无帮助，进而超过6岁前的黄金矫正期，造成视力无法回复的后果。
因此，本发明人鉴于上述缺点，期望能够提出一种具有矫正弱视眼的效能的基于VR技术的弱视训练复健系统及方法，使使用者可轻易操作组装，乃潜心研思、设计组制，以提供使用者便利性。

本说明书的附图为示意图，辅助说明本发明的构思，示意性地表示各部分的相互关系。请注意，为了便于清楚地表现出本发明实施例的各部分的关系。相同或相似的参考标记用于表示相同或相似的部分。
本发明提供一种基于VR技术的弱视训练复健系统，其中，该系统用于训练视力以帮助弱视人群进行视力矫正或复健，该系统适用于虚拟现实装置10，包括VR眼镜本体，设置于VR眼镜本体上的透镜、显示屏、控制模块13和存储器，存储器中存储有影片20，显示屏包括左视屏11与右视屏12，控制模块13用于根据被训练者的裸眼视力控制影片20的播放模式及眼球训练模式；如图19所示，其中，控制模块13包括：
操作设定模块131，用于将欲播放的影片20先依据被训练者的视力来进行影像运动的起迄点设定、移动速度设定、起点与迄点停顿设定及模式设定；其中，操作设定模块131与存储器连接，即操作设定模块131用于设定存储器中影片20的播放参数；
选择视屏模块132，用于依据被训练者的视力将优于弱视眼的优视眼的 左视屏11或右视屏12进行遮蔽或雾化；
影片播放模块133，用于将己设定好的影像运动方式的影片20进行播放，使该影片20的影像框能根据影像运动的设定2来呈现出规则运动或不规则运动，进而使得未被遮蔽或雾化的右视屏12或左视屏11下的弱视眼能随着播放影片20的影像来进行视觉训练；其中，影片播放模块133与显示屏、存储器均连接，即影片播放模块133用于将存储器中的影片20在显示屏上进行播放。
上述操作设定模块131、选择视屏模块132与影片播放模块133之间均为电连接。
在本发明的进一步实施例中，存储器中还存储有视力表，用于被训练者在训练前后进行视力检测，以检测训练结果；控制模块13中还包括编辑模块134，该编辑模块134与存储器连接，用于存储与设置被训练者的视力值。
在本发明的进一步实施例中，选择视屏模块132中遮蔽或雾化方式设置如下：遮蔽即是将显示屏的画面以变黑方式或以黑色对象遮蔽方式；雾化即将显示屏中的画面模糊度进行调整，以降低优视眼的可视度。也就是说，左视屏11或右视屏12的遮蔽为将该视屏以画面变黑方式或以黑色对象遮蔽方式，使位于视屏下的具有优视眼能放弃视觉追踪运动，而该左视屏11或右视屏12的雾化为将画面的模糊度进行调整(如图4至图13所示)，以模糊可视的视力，即降低优视眼的可视度，如将画面的模糊度调整为480×480，使优视眼虽然看不清楚但仍可以追踪影像，以配合弱视眼来协同视觉追踪并同时训练双眼合作。
在本发明的进一步实施例中，影片播放模块133中的规则运动或不规则运动设置如下：规则运动即将影片20的影像框会以顺时针方向来移动或逆时针方向来移动，并在移动后的位置处进行影像画面的播放，在一定时间后，再移动至下一位置处进行影像画面的播放；不规则运动即将影片20的影像框会以前后方向、上下方向、左右方向或交叉方向来任意进行移动，并在移动后的位置处进行影像画面的播放，在一定时间后，再移动至下一位置处进行 影像画面的播放。其中，该规则运动为该影片20的影像框会以顺时针方向来移动或逆时针方向来移动，并在移动后的位置处进行影像画面的播放，在一定时间后，再移动至下一位置处进行影像画面的播放，例如：以顺时针方向12→3→6→9→12移动，或以逆时针方向12→9→6→3→12移动，且影像在每处的位置放映20秒后即向下一方向移动，而每次持续观看15-20分钟后休息10分钟。另外，该不规则运动为该影片20的影像框会以前后方向(如图4及图5所示)、上下方向(如图6及图7所示)、左右方向(如图8及图9所示)或交叉方向(如图10、图11、图12及图13所示)来任意进行移动，并在移动后的位置处进行影像画面播放，在一定时间后，再移动至下一位置处进行影像画面的播放。例如：以12→6→12移动、9→3→9移动、11→5→2→8移动等任意方向进行移动，且影像在每处的位置放映20秒后即向下一方向移动，而每次持续观看15-20分钟后休息10分钟。
在本发明的进一步实施例中，控制模块13中还包括烟花播放模块，烟花播放模块用于在显示屏中直接放映烟花，该烟花为不同样式不同播放频率不同颜色的烟花。其中，烟花播放模块包括插入烟花播放模块与全烟花播放模块，插入烟花播放模块用于在影片20播放过程中的任意时刻插入烟花播放，也就是说，在基于VR技术的弱视训练复健系统中任何一个运动过程中均可以加入烟花，可以是普通烟花，也可以是101烟花。即可以在弱视训练过程中的影片20的影像框运动至每个方向的外端时可以加入烟花视频，还可以在每个方向训练结束时放映烟花视频，具体烟花视频的时间可以为10秒、20秒、30秒或为其他时间，根据具体运动时间进行设置，加入烟花放映的效果是为了增加被训练者视觉上的刺激感，进而更好地锻炼眼部追踪能力。另外，全烟花播放模块用于被训练者根据需要选择只观看烟花播放，即被训练者可以根据自身需要在弱视矫正程序中进行选择全烟花播放模块，该全烟花播放模块即是在显示屏中直接放映烟花，具体地，烟花为不同样式不同播放频率不同颜色的烟花，也就是说，选择全烟花播放模块时显示屏中仅显示烟花视频， 不会显示影片20的播放。
此外，本发明还提供一种基于VR技术的弱视训练复健方法，其中，该方法用于训练视力以帮助弱视人群进行视力矫正或复健，并且该方法适用于虚拟现实装置10，该虚拟现实装置10戴于孩童或成人的眼睛处(如图2所示)，而该虚拟现实装置10能通过设于虚拟现实装置10上的按键或是以无线方式或有线方式来与外部装置连接(图未示)以进行操作控制，其中，该外部装置为遥控器、手机、鼠标或操作板等其中任一种，该虚拟现实装置10包括VR眼镜本体，设置于VR眼镜本体上的透镜、显示屏、控制模块13和存储器，存储器中存储有影片，显示屏包括左视屏11与右视屏12，控制模块13用于根据被训练者的裸眼视力控制影片的播放模式及眼球训练模式；其中，基于VR技术的弱视训练复健方法包括如下步骤：
S100操作设定：将欲播放的影片20先依据被训练者的视力来进行影像运动的起迄点设定211、移动速度设定212、停顿设定213及模式设定214；
S110选择视屏：依据被训练者的视力将优于弱视眼的优视眼的左视屏11或右视屏12进行遮蔽或雾化；
S120影片播放：将己设定好的影像运动的影片20进行播放，使该影片20的影像能根据影像运动的设定21来呈现出规则运动或不规则运动；以及
S130眼球训练：使未被遮蔽或雾化的右视屏12或左视屏11下的弱视眼能随着播放影片20的影像来进行视觉训练。
参见本发明的图1至图18，其为本发明实施例的示意图，而本发明的基于VR技术的弱视训练复健系统及方法的最佳实施方式是运用于两眼不等视状态或两眼视差150度以上的孩童或成年人，使弱视眼能进行视觉训练，以矫正该弱视眼的视力，使具有立体空间的距离感及速度感。
其中，影片20可以是卡通影片、图像影片、游戏影片、电影影片、电视影片等其中任一种或是其他种类的影片20。
需要说明的是，本发明的影片20可以替换为被追踪移动目标，即不一 定在弱视矫正的过程中只用到影片20，还可以是其他可移动物体，只要能够满足在显示屏一侧能够进行随意移动即可。
在本发明的进一步实施例中，如图1所示步骤Sl00操作设定，即是将欲播放的影片20先依据被训练者的视力来进行影像运动的起迄点设定211、移动速度设定212、停顿设定213及模式设定214。其中，虚拟现实装置10在执行弱视矫正过程中，会先出现将欲播放的影片20的影像运动的设定21(如第3图所示)的界面，而该影像运动的设定21有起迄点设定、移动速度设定212、停顿设定213及模式设定214，其中，该起迄点设定211的起点设有距角膜顶点起零距离、模拟6公分、模拟8公分、模拟10公分、模拟12公分、模拟15公分、模拟18公分、模拟20公分、模拟22公分、模拟25公分或模拟30公分，而该迄点设有模拟100公分、模拟120公分、模拟150公分或模拟180公分。例如：假设屈亮度设定：起点8cm←与→迄点l00cm之间变换，通过调节力(D)公式D＝100/距离起点(近点)的调节力及调节力(D)公式D＝l00/距离迄点(远点)的调节力，即可使眼球调节+1250°凸镜←与→+100°凸镜之间随着距离的变化，而调节力量也在随之发生变化。
在本发明的进一步实施例中，步骤Sl00操作设定中的移动速度设定212具体设置为1秒、1.5秒、2秒或3秒，通过该移动速度设定212来确认被训练者的弱视眼的专注力能否跟上影片20的影像的移动速度与节奏，待其被训练者习惯此移动速度与节奏后再慢慢加快速度，以确保弱视眼能调节三连动肌能适应该移动速度，并随时调整移动速度与节奏。
另外，在本发明的进一步实施例中，步骤Sl00操作设定中的停顿设定213设置方式为：影片20停顿间隔为小于0.5秒、0.75秒、1秒或不停顿。其中，本发明通过停顿设定213来使眼肌慢慢由外散开往内收缩来运动，以帮助影像融像，强壮双眼的融像能力。
另外，在本发明的进一步实施例中，步骤Sl00操作设定中的模式设定 214为前后模式、上下模式、左右模式或交叉模式，通过模式设定214来使影片20的影像在被训练者的弱视眼前能出现于不同位置，以吸引弱视眼的视欲力来持续性专注追踪影片20的影像，以训练眼肌力。
另外，在上述步骤S100操作设定之前可以设置有步骤S001视力检测，即在显示屏中呈现出视力图30，以进行检测眼睛的视力(如图14所示)。通过在虚拟现实装置10的左视屏11及右视屏12中出现视力图30(如图16所示)来先检测两眼的裸视的视力，以便作为步骤S100操作设定的步骤的参考值，而该视力图30可以是以常见的英文字母C或E的表示方式，也可以是以各种的图案如动物等来作为表示方式(图未示)，或者为其他大小依次变化的其他物体，其具体并非仅限于字母E的表示方式。
在本发明的进一步实施例中，如图1所示步骤S110选择视屏，即在完成上述步骤Sl00后即进行该步骤S110，该步骤S110即是依据被训练者的视力将优于弱视眼的优视眼的视屏进行遮蔽或雾化。在步骤S100操作设定的步骤后，能依据被训练者的裸视视力来分出优视眼及弱视眼，并将优于弱视眼的优视眼的该虚拟现实装置10的显示屏进行遮蔽(图未示)或雾化，例如左眼为弱视眼时，即将该虚拟现实装置10的右视屏12进行遮蔽或雾化，反之亦然。其中，该显示屏的遮蔽为将该视屏以画面变黑方式或以黑色对象遮蔽方式，使位于显示屏下的具有优视眼能放弃运动，而该显示屏的雾化为将画面的清晰度进行模糊调整(如图4至图13所示)，以模拟可视的视力，即降低优视眼的可视度，如将画面的模糊度调整为480×480，使优视眼虽然看不清楚但仍可以追踪影像，以配合弱视眼来协同运动。其中，画面模糊度的调节方式可是调节分辨率、调节对比度和亮度或调节不透明度等方式。
在本发明的进一步实施例中，如图1所示步骤S120影片播放，即将己设定影像运动方式的影片20进行播放，使该影片20的影像框能根据影像运动的设定21来呈现出规则运动或不规则运动。在步骤S110选择视屏步骤后，即将已经设定好影像运动的影片20进行播放，使该影片20的影像框能根据 影像运动的设定21包括起迄点设定211、移动速度设定212、停顿设定213及模式设定214(如图3所示)来呈现出规则运动或不规则运动。其中，该规则运动为该影片20的影像框会以顺时针方向来移动或逆时针方向来移动，并在移动后的位置处进行影像画面的播放，在一定时间后，再移动至下一位置处进行影像画面的播放，例如：以顺时针方向12→3→6→9→12移动，或以逆时针方向12→9→6→3→12移动，且影像在每处的位置放映20秒后即向下一方向移动，而每次持续观看15-20分钟后休息10分钟。另外，该不规则运动为该影片20的影像框会以前后方向(如图4及图5所示)、上下方向(如图6及图7所示)、左右方向(如图8及图9所示)或交叉方向(如图10、图11、图12及图13所示)来任意进行移动，并在移动后的位置处进行影像画面播放，在一定时间后，再移动至下一位置处进行影像画面的播放；例如：以12→6→12移动、9→3→9移动、11→5→2→8移动等任意方向进行移动，且影像在每处的位置放映20秒后即向下一方向移动，而每次持续观看15-20分钟后休息10分钟。而完成上述步骤S120后即进行下一步骤S130。
在本发明的进一步实施例中，如图1所示步骤S130眼球训练，即在完成上述步骤Sl20后即进行该步骤S130，该步骤S130即是使未被遮蔽或雾化的左视屏11或右视屏12下的弱视眼能随着播放影片20刻的影像来进行视觉训练。在该步骤S130中，使未被遮蔽或雾化的左视屏11或右视屏12下的弱视眼能随着播放影片20的影像来进行规则运动或不规则运动，以强化弱视眼的眼肌的三连动(适当的收缩与放松及交互运动)，使被训练者的弱视眼经过视觉训练后能被调节得更好，以达到正常的标准视力。
本发明的方法在完成上述步骤S130眼球训练之后可以检视该弱视眼经过上述步骤后的视力改善情形，即可以设置有步骤S140视力检测，即在视屏中呈现出视力图30，使未被遮蔽或雾化的视屏下的弱视眼在经过眼球训练步骤后检测其视力(如图15所示)。通过在虚拟现实装置10的显示屏中出 现视力图30(如图16所示)，而该视力图30可以是以常见的英文字母C或E的表示方式，也可以是以各种的图案如动物等来作为表示方式，使未被遮蔽或雾化的视屏下的弱视眼能进行检测该弱视眼的视力的改善程度。
在本发明的进一步实施例中，如图17所示，其中眼球训练可以具体包括步骤眼外肌训练S1301，即将显示屏中的一个影片20的影像框以中间为起点，向显示屏中的左、右、上或下任一端进行移动，再由任一端移动至中间，来回运动多次，其中运动方式包括连续式或跳跃式运动方式。在该步骤眼外肌训练S1301中，具体训练的方式可以是将显示屏中的一个影片20的影像框由中间开始开散向显示屏的水平方向两端开始运动，其中一个影片20在向两端运动的过程中会逐渐分裂为两个影片20，然后两个影片20由两端又会逐渐运动至中间位置，如此来来回回运动多次，一般为6次或其他数值的次数，或重复运动5分钟，当然影片20除了水平移动方式之外，还可以是前后移动，这样设置可以加强双眼的融像能力。或者，具体训练的方式还可以是将显示屏中的一个影片20在显示屏中顺时针或者逆时针运动，其中可以先顺时针旋转5圈，然后再逆时针旋转5圈，如此来来回回运动多次，一般为10次或其他数值的次数，当然影片20除了水平移动方式之外，还可以是前后移动，这样设置可以加强双眼的融像能力。
在本发明的进一步实施例中，如图17所示，其中眼球训练还可以具体包括步骤斜位眼训练S1302，即将显示屏中的一个影片20的影像框以中间为起点，向显示屏中的右上、右下、左上或左下方向进行移动，然后再移动至中间，来回运动多次，其中运动方式包括连续式或跳跃式运动方式。在该斜位眼训练S1302中，具体训练的方式可以是一个影片20的影像框由中间位置开始单向移动，如果是左眼遮蔽，则影片20就向右上、水平、右下方向运动，运动方式可以是连续式运动，也可以是跳跃式运动方式，跳跃式运动方式每次具体可以设置为跳跃4-5格；如果是右眼遮蔽，则影片20的影像框就向左上、水平、左下方向运动，运动方式可以是连续式运动，也可以是跳跃式运 动方式，跳跃式运动方式每次具体可以设置为跳跃4-5格。其中，在向右上、右水平、右下、左上、左水平或左下运动的过程中，具体在每个方向上运动的次数相同或不同均可以，例如在左眼遮蔽情况下，影片20的影像框可以先向右上方向运动来回运动3次，然后向右水平方向来回运动2次，然后再向右下方向来回运动3次，或者还可以是向右水平方向运动1次，再向右下方向运动1次，再向右上方向运动1次，如此运动方式循环5分钟。
在本发明的进一步实施例中，在影片20的影像框运动至屏幕中的任何位置处加入步骤烟花模式S150，该烟花模式S150包括全烟花模式和/或插入烟花模式。
其中，插入烟花模式就是在基于VR技术的弱视训练复健方法中任何一个步骤中均可以加入烟花，或者是在影片的影像框运动至屏幕中的任何位置处加入烟花模式，该烟花可以是普通烟花，也可以是101烟花。例如，在眼球训练步骤S130中的眼外肌训练S1301中可以在影片20的影像框运动每至显示屏两端及返回至中间位置时均可以放映烟花，另外还可以在每训练15分钟结束放映10秒钟的烟花，优选为101烟花视频；此外，在眼球训练步骤S130中的斜位眼训练S1302中在影片20运动至每个方向的外端时可以加入烟花视频，还可以在每个方向训练结束时放映烟花视频，具体烟花视频的时间可以为10秒、20秒、30秒或为其他时间，根据具体运动时间进行设置，加入烟花放映的效果是为了增加被训练者视觉上的刺激感，进而更好地锻炼眼部追踪能力。
其中，全烟花模式为在显示屏中直接放映烟花，该烟花为不同样式不同播放频率不同颜色的烟花，即被训练者可以根据自身需要在弱视矫正程序中进行选择全烟花模式，该全烟花模式即是在显示屏中直接放映烟花，具体地，烟花为不同样式不同播放频率不同颜色的烟花，也就是说，选择全烟花模式时显示屏中仅显示烟花视频，不会显示影片20的播放。
需要说明的是，本发明的基于VR技术的弱视训练复健系统及方法中影 片20的影像框在运动的过程中均保持影像框在显示屏的水平面内，即影像框在运动过程中仅仅是影像框整体在发生运动，而影像框本身不发生运动或转动。
以上对本发明的基于VR技术的弱视训练复健系统及方法的实施方式进行了说明。对于本发明的基于VR技术的弱视训练复健系统及方法的具体特征可以根据上述披露的特征的作用进行具体设计，这些设计均是本领域技术人员能够实现的。而且，上述披露的各技术特征并不限于已披露的与其它特征的组合，本领域技术人员还可根据本发明之目的进行各技术特征之间的其它组合，以实现本发明之目的为准。
