1. A method for acquiring an object's attention information, comprising:
displaying, at a two-dimensional (2D) display area, a three-dimensional (3D) virtual image in a virtual scene, the 3D virtual image being a 3D image corresponding to a virtual object in the virtual scene mapped from a physical object, the displaying comprising mapping the 3D virtual image to the 2D display area from a viewpoint position in the virtual scene, one or more constituent components of the virtual object corresponding, one-to-one, to one or more constituent components of the physical object;
determining a target object of the 3D virtual image displayed in the 2D display area, the target object being at least a portion of the 3D virtual image displayed in the 2D display area representing a subset of the one or more constituent components of the virtual object; and
based on the target object, determining, without using an eye tracking device, an attention focus object of the 3D virtual image, the attention focus object belonging to at least a part of the 3D virtual image, the attention focus object representing at least one first constituent component of the subset of the one or more constituent components of the virtual object, the attention focus object being indicative of an attention focus of a user on a constituent component of the physical object corresponding to the at least one first constituent component of the virtual object.
