Abstract: Some techniques are described herein for managing requests for placement of a user interface object within an environment. Some techniques are described herein for requesting placement of a user interface object within an environment.

Abstract: Aspects of the subject technology provide volumetric interface layers for an electronic device. The volumetric interface layers may be discrete distance layers, each having a respective distance from the electronic device, in which user interfaces can be displayed by the electronic device. Applications running on the electronic device may be provided with the ability to request display of a user interface for the application in one of the discrete distance layers. In one or more implementations, the discrete distance layers may be semantically labeled, and may be requested by an application using their semantic labels.

Abstract: In one implementation, a method of recentering an application is performed by a device including a display, one or more processors, and non-transitory memory. The method includes obtaining a transform between a three-dimensional application coordinate system and a three-dimensional world coordinate system. The method includes determining a location of a virtual object in the three-dimensional application coordinate system. The method includes displaying, on the display, the virtual object at a location in a two-dimensional display coordinate system based on the location of the virtual object in the three-dimensional application coordinate system, the transform, and a first pose of the device. The method includes detecting a recentering trigger. The method includes in response to detecting a recentering trigger, updating the transform to an updated transform based on a second pose of the device.

Abstract: Aspects of the subject technology provide for various user interface modes for a user interface of an application. The user interface modes may include one or more bounded modes, a single application mode such as an exclusive mode, and/or one or more full screen modes. In one or more implementations, access to various types of information by the application may be constrained based on the user interface mode of the user interface.

Abstract: A device implementing a system for providing query completion suggestions includes at least one processor configured to receive a partial query, and derive one or more query completion suggestions for the partial query from content items that are locally stored on the device, each respective query completion suggestion being associated with metadata extracted from one of the content items from which the respective query completion suggestion was derived. The at least one processor is further configured to rank the one or more query completion suggestions based at least in part on the metadata associated with each of the one or more query completion suggestions. The at least one processor is further configured to provide, for display, at least one of the one or more ranked query completion suggestions.
