Disclosed are a method and a device for determining the position of a virtual object in a virtual space. The method comprises: detecting whether a predetermined triggering condition is met; when the predetermined triggering condition is met, acquiring at least three sampling points by sampling a movement trajectory of a peripheral device in a reality space; when the movement trajectory forms a loop, determining a reality space plane on which the sampling points exist; converting the reality space plane into a target plane in the virtual space according to a preset transformation relation; and determining the position of a virtual object in the virtual space by setting a designated side of the virtual object on the target plane. By the method and the device according to the present invention, the position of a virtual object in a virtual space may be determined according to the position of a reality object in a reality space, thereby determining the position of the virtual object in the virtual space.

A short-distance optical amplification module and a near-eye display optical module using the same in the present invention relates to an optical amplification module applicable for short distance and an optical module using the same for near-eye display. The purpose of the present invention is to provide an optical amplification module for large-multiple amplification within a short distance (less than 5 cm) and a near-eye display optical module using the same to achieve super large field of view within a short distance (less than 3 cm). The short-distance optical amplification module in the present invention comprises a first 45 degree phase delay sheet (), a partial-transmission and partial-reflection curved lens (), a second 45 degree phase delay sheet () and a reflective polarizing sheet () which are sequentially arranged. The near-eye display optical module in the present invention comprises a display screen () disposed on the side of the first 45 degree phase delay sheet () away from the partial-transmission and partial-reflection curved lens ().
