Abstract: Various implementations of the systems, methods, and electronic devices described herein estimate three-dimensional (3D) size and position of objects. An example process may include obtaining sensor data for a sequence of frames, determining a representation of an object, and determining 3D positions and size estimates. For each frame that includes image data and depth data, the 3D position is determined based on the device pose data and the depth data for each corresponding frame, and the size estimate is determined based on the image data and the depth data. For each frame of the sequence of frames that includes image data and excludes depth data, the size estimate is determined based on a prior size estimate from a prior frame, and the 3D position is determined based on the size estimate of the representation of the object and a portion of the image data.

Abstract: Providing a visual treatment based on proximity to an obstruction includes collecting, by a device, a sensor data for an environment, and determining a velocity of the device. A boundary of a volume around the device is determined based on the velocity. If a physical object is detected within the boundary based on the sensor data, then a notification procedure is initiated. The boundary of the volume dynamically changes as the velocity of the device or user changes.

Abstract: In some embodiments, an electronic device presents an M R environment including real content and/or virtual content. In some embodiments, a client application provides an API with a target region of the MR environment, one or more criteria, and a presentation effect. In response to the one or more criteria being satisfied, the electronic device presents the target region of the MR environment with the presentation effect.

Abstract: In some embodiments, a computer system controls a user interface element based on directional control input. In some embodiments, a computer system performs an operation in connection with a virtual content item based on input focus. In some embodiments, a computer system reduces the visual prominence of virtual content that is obscuring visibility of one or more objects. In some embodiments, a computer system reduces the visual prominence of virtual content that is obscuring visibility of one or more objects. In some embodiments, a computer system scrolls through paginated content based on directional control input. In some embodiments, a computer system reduces visibility of a first portion of a hand without reducing visibility of a second portion. In some embodiments, a computer system reduces a visual prominence of a portion of virtual content to increase a visibility of one or more hands.
