为增强虚拟空间的真实性，实现用户与虚拟空间中虚拟物件的交互，电子设备在构建虚拟空间时，常常需要预先选择现实世界中存在的一些从设备，并对应在虚拟空间中构建与这些该从设备相对应的虚拟物件。当用户在现实空间中移动这些从设备时，这些从设备对应的虚拟物件也会在虚拟空间中对应进行移动，从而可以实现用户与虚拟空间中虚拟物件的交互。例如，在构建虚拟空间时，可以在虚拟空间中设置一个虚拟手掌，该虚拟手掌与现实空间中的数据手套相对应，当用户在现实空间中转动该数据手套时，该虚拟手掌也对应进行转动，从而使用户可以控制虚拟空间中物件，实现用户与可能空间中虚拟物件的交互。
由此可以看出，为确保用户与虚空间中虚拟物件的交互能够实现，就需要从设备在现实空间中发生姿态角变化时，对应的虚拟物件在也在虚拟空间中进行相应的姿态角变化。

步骤103，主设备采用与所述预定触发条件对应的计算方式，根据所述初始姿态角计算出所述当前姿态角对应的目标姿态角。
在计算目标姿态角N时，可以首先确定与所述预定触发条件相对应的姿态角转换函数，所述姿态角转换函数可以包括用于以所述初始姿态角M1及所述当前姿态角M2为输入参数计算所述目标姿态角N的第一姿态角转换函数，或者也可以包括用于以所述初始姿态角M1、所述当前姿态角M2及指定时长t为输入参数计算所述目标姿态角N的第二姿态角转换函数。
所述第一姿态角转换函数可以用f(M1，M2)表示，所述第二姿态角转换函数可以用f(M1，M2，t)表示。根据实际需求的不同，所述第一姿态角转换函数及第二姿态角转换函数的具体内容也可以各不相同，例如，所述第一姿态角转换函数可以为f(M1，M2)＝M2-M1，所述第二姿态角转换函数可以为f(M1，M2，t)＝(M2-M1)×t等。
主设备可以首先确定与所述预定触发条件相对应的第一姿态角转换函数，所述第一姿态角转换函数用于以所述初始姿态角及所述当前姿态角为输入参数计算所述姿
态角；然后以所述初始姿态角及所述当前姿态角为输入参数，使用所述第一姿态角转换函数计算出所述姿态角。
或者，主设备也可以首先确定与所述预定触发条件相对应的第二姿态角转换函数，所述第二姿态角转换函数用于以所述初始姿态角、所述当前姿态角及所述指定时长为输入参数计算虚拟空间初始姿态角；然后以所述初始姿态角、所述当前姿态角及所述指定时长为输入参数，使用所述第二姿态角转换函数计算出所述虚拟空间初始姿态角。
使用第一姿态角转换函数或第二姿态角转换函数计算出姿态角之后，主设备可以直接将该姿态角作为用于指示虚拟物件显示位置的目标姿态角N，也可将该姿态角作为虚拟空间初始目标姿态角Nt，进一步计算后得出所述目标姿态角N。
主设备可以根据所述虚拟空间初始目标姿态角Nt及指定参考点姿态角计算出所述目标姿态角N，其中所述指定参考点是指虚拟空间坐标系中与现实空间姿态角系坐标原点相对应的坐标点。即N＝Vt+K，其中，K为虚拟空间中的指定参考姿态角。通过设置不同的指定参考姿态角，可以实现根据需要设置虚拟物件在虚拟空间中的展示的基准角度，从而避免从设备在现实空间中的位置限制虚拟设备在虚拟空间中的显示角度。
例如，在第一姿态角转换函数f(M1，M2)＝M2-M1时，根据需要，可以将M2-M1的值M作为目标姿态角N；也可以根据虚拟空间中的指定参考点进行进一步计算，将M+K作为值作为目标姿态角N。
步骤104，主设备将所述虚拟物件的姿态调整为所述指定坐标系中所述目标姿态角所指示的姿态。
在所述目标姿态角N确定之后，可以将虚拟物件以所述目标姿态角N所指示的角度进行设置，从而实现根据从设备在现实空间中的角度变化调整虚拟物件在虚拟空间中的显示角度。
采用本实施例，主设备可以根据从设备在现实空间中的角度变化，对应调整虚拟物件在虚拟空间中的显示角度，从而实现在设备在现实空间中发生角度变化时，对应的虚拟物件在也在虚拟空间中进行相应的角度调整。
由于在现实应用中，从设备除了会发生姿态变化之外，还会发生位置移动，例如外设设备可能会从一个地方移动到另一个地方。因此，主设备除了需要实现在从设备
在现实空间中移动时，对应的虚拟物件在也在虚拟空间中进行相应的移动之外，还需要实现在从设备在现实空间中发生角度变化时，对应的虚拟物件在虚拟空间中进行相应的角度调整。因此在另一个实施例中，图2所示，在步骤104之后还可以包括：
步骤105，当所述预定触发条件满足时，主设备获取初始三维坐标E1及当前三维坐标E2，其中，所述初始三维坐标E1是指在满足所述预定触发条件时，所述从设备在现实空间坐标系中的位置坐标，所述当前三维坐标E2是指在满足所述预定触发条件并经过指定时长t之后，所述从设备在所述现实空间坐标系中的位置坐标，所述现实空间坐标系为以现实空间中以指定点为原点所建立的三维坐标系。
在满足预定触发条件时，主设备可以获取从设备的初始三维坐标E1及当前三维坐标E2。
步骤106，主设备采用与所述预定触发条件对应的计算方式，根据所述初始三维坐标E1计算出所述当前三维坐标E2对应的目标三维坐标V。
在计算目标三维坐标V时，可以首先确定与所述预定触发条件相对应的动作函数，所述动作函数可以包括用于以所述初始三维坐标E1及所述当前三维坐标E2为输入参数计算所述目标三维坐标V的第一动作函数，或者也可以包括用于以所述初始三维坐标E1、所述当前三维坐标E2及指定时长t为输入参数计算所述目标三维坐标V的第二动作函数。
所述第一动作函数用f(E1，E2)表示，所述第二动作函数可以用f(E1，E2，t)表示。根据实际需求的不同，所述第一动作函数及第二动作函数的具体内容也可以各不相同，例如，f(E1，E2)＝E2-E1，f(E1，E2，t)＝(E2-E1)×t等。
主设备可以首先确定与所述预定触发条件相对应的第一动作函数，所述第一动作函数用于以所述初始三维坐标及所述当前三维坐标为输入参数计算所述三维坐标；然后以所述初始三维坐标及所述当前三维坐标为输入参数，使用所述第一动作函数计算出所述三维坐标。
或者，主设备也可以首先确定与所述预定触发条件相对应的第二动作函数，所述第二动作函数用于以所述初始三维坐标、所述当前三维坐标及所述指定时长为输入参数计算虚拟空间目标三维坐标；然后以所述初始三维坐标、所述当前三维坐标及所述指定时长为输入参数，使用所述第二动作函数计算出所述目标三维坐标。
使用第一动作函数或第二动作函数计算出三维坐标之后，主设备可以直接将该三
维坐标作为用于指示虚拟物件显示位置的目标三维坐标V，也可将该三维坐标作为虚拟空间初始目标三维坐标Vt，进一步计算后得出所述目标三维坐标V。
主设备可以根据所述虚拟空间初始目标三维坐标Vt及指定参考点三维坐标计算出所述目标三维坐标V，其中所述指定参考点是指虚拟空间坐标系中与现实空间三维坐标系坐标原点相对应的坐标点。即V＝Vt+Z，其中，Z为虚拟空间中的指定参考点三维坐标。通过设置不同的指定参考点，可以实现根据需要设置虚拟物件在虚拟空间中的展示的基准位置，从而避免从设备在现实空间中的位置限制虚拟设备在虚拟空间中的显示位置。
例如，在第一动作函数f(E1，E2)＝E2-E1时，根据需要，可以将E2-E1的值E作为目标三维坐标V；也可以根据虚拟空间中的指定参考点进行进一步计算，将E+Z作为值作为目标三维坐标V。
步骤107，将所述虚拟物件调整至所述虚拟空间中任意一个指定坐标系中所述目标三维坐标V所指示的位置。
在所述目标三维坐标V确定之后，可以将虚拟物件设置在所述目标三维坐标V所指示的位置，从而实现根据从设备在现实空间中的位置变化调整虚拟物件在虚拟空间中的显示位置。
采用本实施例，主设备可以根据从设备在现实空间中的移动，对应调整虚拟物件在虚拟空间中的位置，从而实现在设备在现实空间中移动时，对应的虚拟物件在也在虚拟空间中进行相应的移动。
