背景技术
虚拟实境(以下简称为VR)是一个利用电脑类比模块所产生的三维空间虚拟世界，早在西元1950年就有学者提出类似的概念。随着科技的进步，近年来VR技术逐渐被发扬光大，2016年更是被称为VR元年。
一般来说，VR使用者会通过VR系统来体验VR技术。VR系统通常包含一头戴式装置以及一控制器，有些VR系统还包含可用以侦测VR操作者的肢体动作的体感侦测装置。在体验VR技术时，VR使用者会配戴头戴式装置以观看VR世界的VR场景，手上则会持有控制器以控制VR使用者在VR世界中的动作。
其中，所述头戴式装置中配有陀螺仪(Gyroscope)与重力加速度计(G-sensor)感测器，以侦测VR使用者的头部的位移。所述控制器可以是一个游戏手把、一个遥控器、一个键盘、一个鼠标或由上述控制器所构成的一任意组合。
所谓VR世界中的移动，是指VR使用者通过头戴式装置所见VR场景中物件的移动。举例来说，若VR使用者通过控制器发出「前进」指令，VR场景中的物件会逐渐靠近VR使用者，此时VR使用者会感觉自己在前进；若VR使用者通过控制器发出「后退」指令，VR场景中的物件会逐渐远离VR使用者，此时VR使用者会感觉自己在后退。
上述的原理是通过VR场景中的物件移动所产生人体视觉上的效果，使得VR使用者感觉自己在VR世界中移动。
尽管VR技术已逐渐成熟，部分VR使用者在体验VR技术时依旧会出现晕眩感、恶心感、疲劳感及眼花等动晕症的症状。其原因在于当人体感觉到的运动与视觉上的画面不相符时，大脑对身体平衡状态及空间方位的判断就会出现误差，进而表现为动晕症。
为了解决上述问题，一些程序开发者使用手拉、手臂摆动、推动仓鼠球等 控制方法，让VR使用者在VR世界中缓慢移动以减缓动晕症的症状。然而，这些移动方式的速度过于缓慢，并不符合VR使用者在真实世界中的移动方式。
此外，部分程序开发者使用传送或瞬间移动的控制方式，让VR使用者在VR世界中移动。藉由画面瞬间的改变，以降低VR使用者视觉上的刺激，进而避免产生恶心感。然而，上述方法并不符合VR使用者在真实世界中的移动方式，因此也降低了VR使用者的沉浸体验感受。
还有一些程序开发者则采用让VR使用者乘坐在交通工具上的方式在VR世界中移动，让VR使用者感受到自己坐在一辆车、一只动物、一艘太空船上以减缓眩晕感。然而，这种控制方法依旧会产生类似晕车或晕船的症状。
US10890976B2揭示了一种以压力控制运动回馈的一VR平台。该VR平台会感测VR使用者的实际压力运动方向，并将该方向信息传输至一PC。该PC会计算并传输一物理运动回馈至平台，使该平台移动或振动，进而使VR使用者在VR世界中有更真实的体验。尽管US10890976B2的发明可以减缓动晕症的影响，但是该发明有着使用上的不便性。VR使用者必须站立于一重力感应装置上才能进行操作，且VR使用者的移动范围亦受限于该重力感应装置的范围大小，其中所述重力感应装置还必须占据一些空间，也造成使用者的居家空间遭到挤压，进而降低普及性。
发明公开
有鉴于此，本发明的目的在于提出一种虚拟实境控制方法。所述方法包含以下步骤：接收一VR使用者通过一控制器所发出的一位移控制指令，该位移控制指令系选自前进、后退、左移、右移、停止、上移、下移及其组合所构成的群组；侦测该VR使用者的头部的一晃动的一晃动方向；以及根据一指令匹配规则判断该位移控制指令与该晃动的晃动方向是否匹配；其中，当该位移控制指令与该晃动的晃动方向匹配时，执行该位移控制指令，当该位移控制指令与该晃动的晃动方向不匹配时，不执行该位移控制指令。
在上述程序控制方法的一些实施例中，所述侦测该晃动方向的步骤是在接收该位移控制指令后的一预设时间内执行。
在上述程序控制方法的一些实施例中，执行该位移控制指令的步骤是控制 该VR场景中的物件根据该位移控制指令的方向移动。
在上述程序控制方法的一些实施例中，执行该位移控制指令的步骤是控制该VR场景中的物件根据相反于该位移控制指令的方向移动。
在上述程序控制方法的一些实施例中，还包含：判断该晃动的一晃动位移是否大于一位移阈值，当该晃动的晃动位移大于该位移阈值时，始根据该指令匹配规则判断该位移控制指令与该晃动的晃动方向是否匹配。
在上述程序控制方法的一些实施例中，还包含：判断该晃动的一晃动加速度是否大于一加速度阈值，当该晃动的晃动加速度大于该加速度阈值时，始根据该指令匹配规则判断该位移控制指令与该晃动的晃动方向是否匹配。
在上述程序控制方法的一些实施例中，当该晃动的晃动加速度大于该加速度阈值时，该VR场景的移动速度增加。
在上述程序控制方法的一些实施例中，还包含：判断该晃动的一晃动位移是否大于一位移阈值以及判断该晃动的一晃动加速度是否大于一加速度阈值，当该晃动的晃动位移大于该位移阈值且该晃动的晃动加速度大于该加速度阈值时，始根据该指令匹配规则判断该位移控制指令与该晃动的晃动方向是否匹配。
在上述程序控制方法的一些实施例中，是以一头戴式装置侦测该VR使用者的头部的晃动。
在上述程序控制方法的一些实施例中，是以一体感侦测装置侦测该VR使用者的头部的晃动。
综上所述，本发明的虚拟实境控制方法是基于人体自然的前庭系统的原理，将用以刺激前庭系统的一头部晃动动作与VR系统的操作结合，以达到避免产生动晕症的效果。

实现本发明的最佳方式
下面结合附图对发明的结构原理和工作原理作具体的描述：
前庭系统是人体重要的平衡感受器官，其中包含了可以感受头部三度空间方向的加速度的三个半规管(外半规管、上半规管及后半规管)。当人体在进行各个方向的变速运动时，前庭系统会受到刺激并为大脑提供信息，使得人体的视觉反应可以跟上实际的运动。但是，人体在进行等速运动时，前庭系统并不会发挥作用。
举例来说，当我们在骑脚踏车时，我们会在起步的阶段(即变速运动)感受到前进。此时人体的前庭系统会受到变速运动的刺激，使得人体可以适应视觉上的画面移动。当我们接续惯性运动方向等速前进时，尽管前庭系统不再受到刺激，人体依旧可以适应视觉上的画面移动，而没有动晕症的症状。
参照图1至图4，其中图1绘示出本发明的一例示虚拟实境控制方法流程图，图2至4分别绘示出VR使用者在VR世界中执行前进操作的示意图(一)至(三)。本实施例中，VR使用者是通过VR系统执行一VR程序，其中VR系统包含头戴式装置2与控制器3。所述控制器可以是一个游戏手把、一个遥控器、一个键盘、一个鼠标、一对控制器(左/右)、一个触控板、配有陀螺 仪与重力加速度计感测器或配有摄影机可以侦测空间图像变化并计算位移的位移感测器或由上述控制器所构成的一任意组合。用来执行VR程序的处理器可以是直接设置于头戴式装置中，或者是另外设置于一电脑主机中。当用来执行VR程序的处理器是另外设置于一电脑主机中时，电脑主机也视为VR系统的一部分。所述电脑主机可以是智能手机、个人电脑、远程伺服器，抑或是市售的游戏主机，例如任天堂Switch主机、索尼PS主机与微软Xbox主机。
如图2所示，VR使用者的手部握持着控制器3，头部1配戴着头戴式装置2，眼睛通过头戴式装置2看见VR场景4，且VR场景4包含物件41。当VR使用者按下控制器3上的按键31而发出「前进」的位移控制指令时，此时VR系统会接收到「前进」的位移控制指令时(步骤S10)尚不会执行位移控制指令，亦即VR使用者在VR世界中仍保持原地不动(原移动操作状态)。所谓原移动操作状态是指，当VR使用者按下控制器3上的按键31前若处于静止状态，则原移动操作状态为静止状态；当VR使用者按下控制器3上的按键31前若处于移动状态，例如处于前进移动状态，则原移动操作状态为前进移动状态。
接着，在VR使用者发出「前进」的位移控制指令后的一预设时间内，头戴式装置2会侦测VR使用者的头部1的晃动方向(步骤S20)，然后VR系统会根据如图14所示的指令匹配规则50(下称指令匹配表50)判断上述位移控制指令与上述晃动方向是否匹配(步骤S30)，其中预设时间可以是1秒或者小于1秒。指令匹配表50可以是预储存于头戴式装置2或电脑主机中，或者是伴随着VR程序的执行而载入头戴式装置2或电脑主机中。需特别说明，本实施例虽以头戴式装置2侦测VR使用者的头部1的晃动方向，然而晃动方向的侦测也可以通过体感侦测装置来实现。此外，在一些实施例中，头戴式装置2可以在VR使用者发出「前进」的位移控制指令的一持续时间内侦测VR使用者的头部1的晃动方向，其中持续时间是为VR使用者持续按压控制器3上的按键31的时间长短。
如图3所示，当使用者通过控制器3发出「前进」的位移控制指令，但头部1的晃动方向却为向左晃动时，此时VR系统根据指令匹配表50判断为「不匹配」，因此VR系统不执行VR使用者所发出的「前进」的位移控制指令(步骤S40)，仅控制VR场景4中的物件41向右摆动(相当于VR使用者的头部 1在VR世界中向左晃动)。
如图4所示，当使用者发出「前进」的位移控制指令，且头部1的晃动方向为向前晃动时，此时VR系统根据指令匹配表50判断为「匹配」，因此VR系统会执行VR使用者所发出的「前进」的位移控制指令(步骤S50)，以控制VR场景4中的物件41逐渐靠近VR使用者(相当于VR使用者在VR世界中前进)。
在本实施例中，当VR使用者单纯通过控制器3发出位移控制指令时，并无法直接造成VR世界中的相应改变。唯有位移控制指令的移动操作与VR使用者的头部1晃动方向相互匹配时，VR系统始会执行控制器3发出位移控制指令，并使VR场景4做出相应于该位移控制指令的变化。如此一来即可确保VR场景4变化前，VR使用者的头部1已经预先做出反应而刺激内耳的前庭系统，从而避免动晕症的发生。
在一些实施例中，VR使用者可根据不同情境下的需求，自行增加或减少指令匹配表50中的移动操作(例如攀爬、飞翔、趴下、翻滚等)，且可自定义各移动操作的匹配条件。
在一些实施例中，头戴式装置2除了侦测VR使用者的头部1的晃动方向外，还可以进一步侦测VR使用者的头部1的晃动的晃动位移，且唯有当晃动位移大于一位移阈值时，VR系统始根据指令匹配表50判断位移控制指令与晃动方向是否匹配。所谓晃动位移系指VR使用者的头部1的晃动幅度大小。若VR使用者的头部1的晃动幅度愈大，则晃动位移愈大；若VR使用者的头部1的晃动幅度愈小，晃动位移愈小。在一些实施例中，上述晃动位移的侦测也可以通过体感侦测装置来实现。
上述位移阈值的功用为过滤人体自然产生的细微晃动。即使人刻意保持肢体不动，但多少仍会产生一些细微的晃动，这些晃动的晃动位移可以视为背景杂讯予以滤除，以避免导致VR系统误判。在一些实施例中，位移阈值可以是固定值也可以通过VR使用者自订。在一些实施例中，位移阈值可以通过机器学习的方式学习当前VR使用者自然产生的细微晃动的程度，进而自适应地调整。
在一些实施例中，头戴式装置2除了侦测VR使用者的头部1的晃动方向外，还可以进一步侦测VR使用者的头部1的晃动的晃动加速度，且唯有当晃 动加速度大于一加速度阈值时，VR系统始根据指令匹配表50判断位移控制指令与晃动方向是否匹配。所谓晃动加速度系指VR使用者的头部1的晃动速度变化大小。若VR使用者的头部1的晃动速度变化愈快，则晃动加速度愈大；若VR使用者的头部1的晃动速度变化愈慢，则晃动加速度愈小。在一些实施例中，上述晃动加速度的侦测亦可通过体感侦测装置来实现。
上述加速度阈值的功用同样是为了过滤人体自然产生的细微晃动。即使人刻意保持肢体不动，事实上仍会产生一些细微的晃动，但这些晃动的速度并不快也不会具有明显的速度变化。藉由加速度阈值的设定，可以将VR使用者非有意为的的头部1的晃动视为背景杂讯(噪声)而予以滤除，避免VR系统误判。
在一些实施例中，上述加速度阈值的另一功用为辅助VR使用者在VR世界中进行移动操作。亦即当VR使用者通过控制器3所发出的位移控制指令的移动操作与VR使用者的头部1晃动方向相互匹配时，VR系统可以根据晃动加速度的信号来改变VR使用者在VR世界中的移动速度。以「前进」移动操作为例，当晃动加速度大于加速度阈值时，VR系统控制VR场景4中的物件41靠近VR使用者的速度会增加(即VR使用者在VR世界中前进的移动速度增加)。
在一些实施例中，VR系统的头戴式装置2系同时侦测VR使用者的头部1的晃动的晃动位移以及晃动加速度，并判断所述晃动位移以及晃动加速度是否分别大于位移阈值与加速度阈值，且唯有晃动位移以及晃动加速度分别大于位移阈值与加速度阈值时，VR系统始根据指令匹配表判断位移控制指令与晃动方向是否匹配。
上述的产生「前进」的位移操作指令的控制方式，除了按下按键31外，也可以是将控制器3上的摇杆「向前」推、滚轮「向前」滚、触控面板「向前」滑或控制器3本身「向前」摆动。
受到人体惯性的影响，当VR使用者的头部1进行一方向的晃动时，头部1会随即进行该方向的反向晃动以回到原先的肢体状态，亦即头部1的晃动是一种往复的位移动作。因此，上述「前进」的移动操作的匹配条件可以是VR使用者的头部1的晃动方向是否为「前方」或「后方」。
同理，上述「前进」位移操作也可以类推适用于「后退」的位移控制指令。
如图5所示，当VR使用者按下控制器3上的按键33而发出「左移」的位移控制指令时，此时VR系统尚不会执行位移控制指令，亦即VR使用者在VR世界中仍保持原地不动(原移动操作状态)。接着，头戴式装置2会侦测VR使用者的头部1的晃动方向，然后VR系统根据如图14所示的指令匹配表50判断上述位移控制指令与上述晃动方向是否匹配。
如图6所示，当使用者通过控制器3发出「左移」的位移控制指令，但头部1的晃动方向却为向前晃动时，此时VR系统根据指令匹配表50判断为「不匹配」，因此VR系统不执行VR使用者所发出的「左移」的位移控制指令，仅控制VR场景4中的物件41向VR使用者摆动(相当于VR使用者的头部1在VR世界中向前晃动)。
如图7所示，当使用者发出「左移」的位移控制指令，且头部1的晃动方向为向左晃动时，此时VR系统根据指令匹配表50判断为「匹配」，因此VR系统会执行VR使用者所发出的「左移」的位移控制指令，以控制VR场景4中的物件41逐渐向右移动(相当于VR使用者在VR世界中向左移动)。
上述产生「左移」的位移控制指令的控制方式，除了按下按键33外，也可以是将控制器上的摇杆「向左」推、滚轮「向左」滚、触控面板「向左」滑或控制器本身「向左」摆动。
受到人体惯性的影响，当VR使用者的头部1进行一方向的晃动时，头部1会随即进行该方向的反向晃动以回到原先的肢体状态，亦即人体头部的晃动是一种往复的位移动作。因此，上述「左移」的移动操作的匹配条件可以是VR使用者的头部1的晃动方向是否为「左方」或「右方」。
同理，上述「左移」的控制方式也可以类推适用于「右移」的控制方式。
如图8所示，当VR使用者按下控制器3上的按键32，以产生「跳跃/上移」的位移控制指令时，此时VR系统尚不会执行位移控制指令，亦即VR使用者在VR世界中仍保持原地不动(或原移动操作状态)。接着，头戴式装置2侦测VR使用者的头部1的晃动方向，然后VR系统根据如图14所示的指令匹配表50判断上述位移控制指令与上述晃动方向是否匹配。
如图9所示，当使用者通过控制器3发出「跳跃/上移」的位移控制指令，但头部1的晃动方向却为向左晃动时，此时VR系统根据指令匹配表50判断为「不匹配」，因此VR系统不执行VR使用者所发出的「跳跃/上移」的位移 控制指令，仅控制VR场景4中的物件41向右摆动(相当于VR使用者的头部1在VR世界中向左晃动)。
如图10所示，当使用者发出「跳跃/上移」的位移控制指令，且头部1的晃动方向为向上晃动时，此时VR系统根据指令匹配表50判断为「匹配」，因此VR系统会执行VR使用者所发出的「跳跃/上移」的位移控制指令，以控制VR场景4中的物件41向下移动(相当于VR使用者在VR世界中跳跃或向上移动)。受到人体惯性的影响，当VR使用者的头部1进行一方向的晃动时，人体头部会随即进行该方向的反向晃动以回到原先的肢体状态，亦即人体头部的晃动是一种往复的位移动作。因此，上述「跳跃」的移动操作的匹配条件可以是VR使用者的头部1的晃动方向是否为「上方」或「下方」。
同理，上述「跳跃/上移」的控制方式也可以类推适用于「蹲下/下移」的控制方式。
如图11所示，在VR使用者持续执行前移移动操作的状态下，当VR使用者释放控制器3上已按下的按键31而发出「停止」的位移控制指令时，此时VR使用者在VR世界中仍会继续保持前进(原移动操作状态)。接着，头戴式装置2会侦测VR使用者的头部1的晃动方向，然后VR系统根据如图14所示的指令匹配表50判断上述位移控制指令与上述晃动方向是否匹配。
如图12所示，当使用者在持续执行前移移动操作的状态下藉由控制器3发出「停止」的位移控制指令，但头部1的晃动方向却为向左晃动时，此时VR系统根据指令匹配表50判断为「不匹配」，因此VR系统不执行VR使用者所发出的「停止」的位移控制指令，并持续执行前移移动操作，使虚拟场景4中的物件41持续接近。此时VR系统只控制VR场景4中的物件41向右摆动(相当于VR使用者的头部1在VR世界中向左晃动)。
如图13所示，当使用者在持续执行前移移动操作的状态下藉由控制器3发出「停止」的位移控制指令，且头部1的晃动方向为「后方」或「前方」时，此时VR系统根据指令匹配表50判断为「匹配」，因此VR系统会执行VR使用者所发出的「停止」的位移控制指令而停止执行前移移动操作，使虚拟场景4中的物件41停止移动。
上述产生「停止」的位移控制指令的控制方式，除了放开已按下的按键31外，也可以是将控制器3上的摇杆「松开」、滚轮「停止」滚、触控面板 「停止」滑、控制器3本身「停止」摆动或者控制器3本身复归VR程序所预设的停止位置(例如从相对于水平面呈倾斜状态复归相对于水平面呈水平状态)。
上述产生「停止」的位移控制指令的控制方式，亦可以是按下控制器3上的「向后」按键、摇杆「向后」推、滚轮「向后」滚、触控面板「向后」滑或者控制器3本身「向后」摆动。
在一些实施例中，例如VR场景是划船、滑雪、操控火箭或其他应用反作用力的移动操作中的任意一种时，此时VR使用者将控制器3向后摆动的位移操作所对应的反而是「前进」的位移控制指令，但这仅仅是上述实施例的一种特殊变化态样，仍然可以通过原指令匹配表50或者设计另一种符合该特殊情境操作的指令匹配表来进行控制。比方说，在VR场景为滑雪的情境下(此时的指令匹配表是为滑雪情境下的设定)，VR使用者是过一对控制器(左/右)进行移动操作，若VR使用者想要左转，是将右控制器向后滑动以产生「左移」的位移控制指令并匹配VR使用者的头部1的晃动方向(「左方」或「右方」)，如此的操作不仅可以模拟实际滑雪时的动作，并同样可以达到避免VR使用者产生动晕症的效果。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
