VIRTUAL DISPLAY DEVICE AND VIRTUAL DISPLAY METHOD

A virtual display device and a virtual display method. The virtual display device comprises: a movement detection unit, which is configured to detect the pose coordinates of a body part of an experiencer, relative to a body reference point, in a virtual space; a degree-of-freedom measurement unit, which is configured to measure the translation amount of the translational degree of freedom of the body reference point of the experiencer, relative to an external reference point, in the virtual space along the X-axis, Y-axis and Z-axis of a space coordinate system, and is further configured to measure the rotation angle of the rotational degree of freedom of the body reference point of the experiencer, relative to the external reference point, in the virtual space and around the X-axis, Y-axis and Z-axis of the space coordinate system; and a main control unit, which is configured to perform calculation according to the pose coordinates, translation amount and rotation angle of the experiencer, so as to obtain the
