用户通过操作手柄300，来完成操作VR桌面中的应用。举例说明，所述第一应用以VR手机投屏为例，当用户通过手柄300点击VR手机投屏图标时，电子设备100响应于上述操作，可以将该应用的内容通过所述VR眼镜200显示，即电子设备100的显示屏幕会被投屏到VR眼镜200中，此时，用户可以在所述VR眼镜200看到所述电子设备100的显示屏幕。
步骤S83，电子设备的显示屏幕投屏到所述VR眼镜中，其中电子设备将显示屏幕由矩形屏幕转换为曲面屏幕。
在一种可能实现的方式中，当电子设备100检测到用户作用于该VR手机投屏图标时，电子设备100将该VR手机投屏的内容通过所述VR眼镜200显示，该VR手机投屏的内容被显示在由矩形屏幕转换得到的曲面屏幕上。因此，用户在VR眼镜200中观看到手机的显示屏幕为曲面显示屏幕，由此可以增强屏幕的视觉效果，将可以进一步增强VR用户的观影体验，特别是在大屏幕播放视频时将带来优良的视觉冲击效果。
在一个实施方式中，电子设备100可以通过转换方法将电子设备的矩形屏幕转为曲面屏幕进行显示。
请参阅图9，为了实现将电子设备的矩形屏幕转为曲面屏幕进行显示，本申请实施例提供了一种VR显示控制方法，可以包括但不限于以下步骤：
步骤S91，获取曲面屏幕的两个端点位置与用户之间的第一角度。
当显示屏幕上所有位置距离用户相同时，可以给用户更加舒适的视觉体验，因此本申请实施例中，曲面屏幕的曲率可以是视听距离为半径的圆的曲率。
结合图10可知，可以在圆弧上取固定点数，将圆弧简化为N段矩形的拼接，进而实现将矩形屏幕转化为曲面屏幕。
本申请实施例中可以通过矩形屏幕的四个顶点位置来计算曲面屏幕的四个顶点位置，并根据所述曲面屏幕的四个顶点位置确定所述曲面屏幕的两个端点位置，然后再确定所述曲面屏幕的两个端点位置与用户之间的第一角度。
举例说明，如图11所示为所述曲面屏幕的俯视图。假设矩形屏幕的两个顶点分别为顶点A和顶点B，那么顶点A’和顶点B’即为曲面屏幕的两个端点。可以理解，假设顶点A和顶点B之间的距离为d1，顶点A’和顶点B’之间的距离为d2，则d1＝d2。
假设用户的位置为O，用户的视听距离为r，因此根据顶点A’和顶点B’之 间的距离d2以及用户的视听距离r，可以计算出顶点A’和顶点B’与用户位置的角度∠A’OB’。
步骤S92，将所述第一角度分割成N等分，并计算出N+1个圆点位置。
作为一种示例，如图10所示，在一种实施方式中，可以将∠A’OB’分割成8等分，因此根据每一屏幕的小角度可以计算出A’、B’、P0、P1、P2、P3、P4、P5、P6的位置，即可以找出A’、B’、P0、P1、P2、P3、P4、P5、P6在VR眼镜中的具体坐标位置。
步骤S93，将N+1个圆点位置拼接起来，以将矩形屏幕转换为曲面屏幕。
本申请实施例可以将A’与P0进行拼接、将P0与P1进行拼接、将P1与P2进行拼接、将P3与P3进行拼接、将P3与P4进行拼接、将P4与P5进行拼接、将P6与B’进行拼接。因此，在将多个圆点位置进行多个矩形拼接之后，即可以实现如图12所示的将矩形屏幕转换为曲面屏幕。
请参阅图13，图13为本申请实施例中手柄300操作曲面屏幕的示意图。
本申请的实施例中，图13中所示出A’、B’、P0、P1、P2、P3、P4、P5、P6为曲面屏的顶点位置，O为用户的位置，O’为VR场景中手柄300的位置，H为手柄射线与曲面屏幕的交点。
可以理解，所述手柄光线的操作方案可以是以下的一种情形：
本申请实施例中，可以将所述手柄300的射线O’H，依次地与矩形A’P0、P0P1、P1P2、P2P3、P3P4、P4P5、P5P6、P6B’进行相交，直到得到O’H与P2P3交于空间中的H点，进而得到H的位置以及在P2P3矩形上的2维坐标。
通过P2P3矩形在整个曲面A’B’中的位置，最后可以得到H点在曲面A’B’上的2维坐标比例，该比例可以作为所述手柄300操作所述电子设备100的触摸位置。本申请实施例通过VR虚拟场景实现人眼最舒适的曲率效果，可以增强用户的视觉体验，提升用户的使用体验。
本申请实施例还提供了一种计算机可读存储介质。所述可读存储介质中存储有计算机指令，所述指令在计算设备上运行时，可以使得计算设备执行前述实施例提供的VR显示控制方法。
对于本领域的技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其他具体形式实现本申请。因此，只要在本申请的实质精神范围之内，对以上实施例所作的适当改变和变化都应该落在本申请要求保护的范围之内。
