A system and method for facilitating user interactions with a virtual space through a graphical chat interface is disclosed. One or more potential inputs to the virtual space and/or virtual space status information may be determined dynamically for a user participating in a chat session through a graphical chat interface. An activity notification may be generated for the user based one the determined potential inputs and/or the virtual space status information. The generated activity notification may comprise graphical representation for the notification and as well as representation information for one or more controls facilitating the user to provide inputs requested by the activity notification through the graphical chat interface. User acceptance to the activity notification via the graphical chat interface may be received. One or more activity commands may be generated based on the received user acceptance and executed in the virtual space.

The present application discloses a method and device of labeling laser point cloud. The method comprises: receiving data of a laser point cloud; constructing a 3D scene and establishing a 3D coordinate system corresponding to the 3D scene; converting a coordinate of each laser point in the laser point cloud into a 3D coordinate in the 3D coordinate system; mapping laser points included in the laser point cloud into the 3D scene respectively according to the 3D coordinate of the laser points; labeling the laser points in the 3D scene.

Preserving user privacy and preventing surveillance on behalf of users of a virtual reality world. One or more plans are available when a privacy or surveillance risk to a user is detected. In one plan, configurable scripts execute on behalf of the user to create a confusing array of clone avatars that obfuscate the real user avatar behavior. A malevolent avatar, attempting to surveil the user, may have difficulty distinguishing the clones from the user and may miss out on private insights he might otherwise have learned from the user's behavior. In another exemplary privacy plan, a copy of part of the virtual world is spawned, occupied exclusively by the user's avatar, and then merged into the main world. Privacy plans may be selected manually or automatically in response to perceived privacy threats to strike a balance between privacy and enjoyment within the virtual world.

Systems and methods for facilitating virtual collaboration between users within virtual environments are disclosed. A plurality of users access a collaborative virtual environment system at various times using interface devices to establish an asynchronous virtual collaboration session in which users collaborate in real-time and/or asynchronously. To enable asynchronous collaboration, data from virtual collaboration session is stored and presented to later users, including user movements and interactions with the environment, user annotation, and audio communications or comments. Other users may then access the data at a later time, and later user interactions, annotations, and audio may likewise be stored for further review by other users.

The present application relates to an extended reality service providing method and system for operation of an industrial installation. More specifically, various types of data required for operation (e.g., inspection, examination, maintenance, repair, and reinforcement) of an industrial installation are digitalized, extended reality content, such as an augmented reality image or a mixed reality image based on the digitalized data, is provided to a site worker or a remote place manager, and the worker and the manager can communicate via a video call in real-time, whereby the work efficiency of the worker and the manager can be enhanced.

Orthodontic devices such as aligners, palatal expanders, retainers, and dental implants can be used to adjust the position of teeth and to treat various dental irregularities. To help the clinician or doctor (i.e., orthodontist) design and plan the subject's treatment plan, a 3D digital model of the subject's teeth, dentition, and gingiva can be constructed from a 3D scan of the subject's mouth, teeth, dentition, and gingiva. The 3D model of the subject's teeth and dentition can be displayed graphically to the doctor on a display using a computing system with memory and software.
