Abstract: Embodiments of the present invention relate to the field of communications technologies, and disclose a method and an apparatus for displaying with a 3D parallax effect, to generate a relatively good 3D parallax effect. A specific solution is: displaying a graphical user interface, where the graphical user interface includes first content, and the first content includes at least two elements; obtaining a first operation instruction which is used for moving, in an area for displaying the first content, at least one first element of the at least two elements; and moving each of the at least one first element by a different distance along a direction of a first straight line, so that the first content has a 3D parallax effect, where the direction of the first straight line is a direction having a preset included angle with a plane in which the graphical user interface is located.

Abstract: Embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a virtual reality (VR) interface generation method and an apparatus, to resolve a conventional problem of interface distortion, a twist, and image quality inconsistency when the interface is viewed by an observer. The method includes: obtaining head position information indicating a head position of an observer; generating a first user interface based on the head position information, where distances from all pixels on the first user interface to the observer are equal; and displaying a second user interface that is generated based on the first user interface.

Abstract: This application provides a text display method and apparatus in virtual reality, and a virtual reality device. The method includes: receiving text information; determining a font size of the text information based on a pixel per degree PPDVR device of a virtual reality VR device, a pixel per degree PPD of an eye of a user, distance information between the text is in VR and the eye of the user, and a correction value α; rendering the text information based on the font size of the text information; and displaying the rendered text information
