Abstract: The present application provides a display control method and apparatus, a device, and a medium. The method includes: obtaining real-time position information of a controller, where the controller is configured to emit a virtual ray pointing to any virtual object in a virtual space; determining a target display form of the virtual ray according to the real-time position information of the controller; and adjusting a display form of the virtual ray according to the target display form of the virtual ray.

Abstract: Embodiments of this application provide an eye tracking method and apparatus, a device, a medium, and a program. By obtaining a sight start point, a sight direction, and a fixation point on a 2D interactive panel of a user, and a size parameter of a collision detection area, a position of the collision detection area is determined based on a position of the fixation point and the size parameter of the collision detection area; An interactive candidate component collided with the collision detection area is determined based on the position of the collision detection area and positions of interactive components on the interactive panel; when there are a plurality of candidate components in the interactive panel, one interactive component is determined from the plurality of candidate components based on position relationships between the plurality of candidate components and the sight start point, the sight direction.

Abstract: The present application discloses a security prompt method and apparatus, a storage medium, a device, and a program product. The method includes: acquiring environmental data of a physical environment; obtaining pose data of a user; classifying entities in the physical environment into danger levels based on the environmental data and the pose data; and presenting a visual indication for security warning when a distance between a collider and a target entity belonging to a target danger level reaches a danger distance threshold, where the collider is constructed based on an interactor corresponding to the user.

Abstract: The present application discloses an interaction method and apparatus, a storage medium, a device, and a program product. The method includes: displaying a virtual object in a virtual reality environment; mapping a real interactor to the virtual reality environment to form a virtual interactor based on a real position of the real interactor; determining an offset between a virtual position and the real position based on an interaction operation between the real interactor and the virtual object in the virtual reality environment; and adjusting the virtual position of the virtual interactor based on the offset to show a position offset state between the virtual position and the real position.

Abstract: The present application provides a human-computer interaction method and apparatus, a device, and a medium. The method includes: determining a gaze point of a line of sight of a user on a target object, the target object being located in a virtual space; adjusting, in response to an interaction gesture for the gaze point, a display form of the gaze point to generate a first interaction point; and interacting with the target object based on the first interaction point.

Abstract: The present application discloses an image display method and apparatus, a storage medium, a device, and a program product. The method can be applied to a virtual reality device and includes: displaying a three-dimensional environment and presenting dynamic visual compensation elements in the three-dimensional environment in response to motion of a current object wearing the virtual reality device.

Abstract: Disclosed herein includes a system, a method, and a non-transitory computer readable medium for rendering a three-dimensional (3D) model of an avatar according to an audio stream including a vocal output of a person and image data capturing a face of the person. In one aspect, phonemes of the vocal output are predicted according to the audio stream, and the predicted phonemes of the vocal output are translated into visemes. In one aspect, a plurality of blendshapes and corresponding weights are determined, according to the corresponding image data of the face, to form the 3D model of the avatar of the person. The visemes may be combined with the 3D model of the avatar to form a 3D representation of the avatar, by synchronizing the visemes with the 3D model of the avatar in time.

Abstract: Private real-time communications are provided between meeting attendees during a meeting using one or more augmented reality headsets. An augmented reality headset worn by a sending meeting attendee continuously monitors a current direction of the sending meeting attendee's gaze during the meeting, and detects that the sending meeting attendee has selected a receiving meeting attendee when the current direction of the sending attendee's gaze intersects with a location of the receiving meeting attendee. The augmented reality headset worn by the sending meeting attendee also receives a messaging command issued by the sending meeting attendee, also based on monitoring the sending meeting attendee's gaze during the meeting. In response to the messaging command, the augmented reality headset worn by the sending meeting attendee automatically transmits the private message to a device associated with the receiving meeting attendee, such as an augmented reality headset worn by the receiving meeting attendee.

Abstract: A technique involves electronically providing live video of a first participant of the online meeting to a set of other participants of the online meeting. The live video displays live physical movement of the first participant. The technique further involves receiving a live video replacement command from the first participant after electronically providing the live video of the first participant of the online meeting to the set of other participants of the online meeting. The technique further involves electronically providing recorded video of the first participant of the online meeting to the set of other participants of the online meeting in place of the live video in response to the live video replacement command. The recorded video displays recorded physical movement of the first participant. Such operation affords the first participant with a period of privacy during the online meeting without calling attention to the video's change in state.
