Abstract: A computer system detects a wrist. In accordance with a determination that first criteria that require an inner side of the wrist facing toward a viewpoint are met, the computer system displays a first user interface object including a plurality of representations of different applications at a first position corresponding to a first location on the wrist. While displaying the first user interface object, the computer system detects that the wrist's position or orientation has changed to satisfying second criteria that requires an outer side of the wrist facing toward the viewpoint. In response, the computer system switches from displaying the first user interface object at the first position to displaying a second user interface object including a plurality of controls for controlling functions at a second position corresponding to a location on a back of a hand attached to the wrist.

Abstract: While displaying a three-dimensional scene including at least a first virtual object displayed with a first value corresponding to a first portion and a second value corresponding to a second portion of the first virtual object at a first location and a first physical surface at a second location, a computer system generates a first visual effect at the second location of the three-dimensional scene, including modifying a visual appearance of a first portion of the first physical surface in the three-dimensional scene in accordance with the first value for the first display property that corresponds to the first portion of the first virtual object; and modifying a visual appearance of a second portion of the first physical surface in the three-dimensional scene in accordance with the second value for the first display property that corresponds to the second portion of the first virtual object.

Abstract: While displaying a three-dimensional environment, a computer system detects a hand at a first position that corresponds to a portion of the three-dimensional environment. In response to detecting the hand at the first position: in accordance with a determination that the hand is being held in a first predefined configuration, the computer system displays a visual indication of a first operation context for gesture input using hand gestures in the three-dimensional environment; and in accordance with a determination that the hand is not being held in the first predefined configuration, the computer system forgoes display of the visual indication.

Abstract: A computer system having a display generation component, one or more input devices, one or more cameras, and one or more attitude sensors receives a request to display an augmented reality view of a physical environment in a first user interface region that includes a representation of a field of view of the one or more cameras. In response to receiving the request, in accordance with a determination that calibration criteria are not met, a calibration user interface object is displayed. In response to detecting a change in attitude of the one or more cameras in the physical environment, at least one display parameter of the calibration user interface object is adjusted in accordance with the detected change. In response to detecting that the calibration criteria are met, the calibration user interface object ceases to be displayed.

Abstract: An electronic device: displays a field of view of a camera at a first magnification and updates the displayed field of view over time based on changes detected by the camera. The field of view includes a view of a three-dimensional space. In response to a first touch input, the device adds a measurement point at a first location in the displayed field of view that corresponds to a first location in the three-dimensional space. As the camera moves, the device displays the measurement point at a location in the displayed field of view that corresponds to the first location in the three-dimensional space. In response to a second touch input corresponding to a current location of the measurement point in the displayed field of view, the device enlarges display of the displayed field of view around the measurement point from the first magnification to a second, greater magnification.

Abstract: A computer system having a display generation component, one or more input devices, and one or more cameras receives a request to display a virtual object in a first user interface region that includes a field of view of the one or more cameras. In response to the request, in accordance with a determination that object-placement criteria are not met, the representation of the virtual object is displayed with a first set of visual properties and with a first orientation that is independent of which portion of the physical environment is displayed in the field of view of the one or more cameras. In accordance with a determination that the object-placement criteria are met, the representation of the virtual object is displayed with a second set of visual properties that are distinct from the first set of visual properties and with a second orientation that corresponds to a plane.

Abstract: A computer system with a display, a touch-sensitive surface, and one or more cameras displays a virtual object in a first user interface region. In response to detecting a first input at a location that corresponds to the virtual object and in accordance with a determination that the first input meets first criteria, the virtual object is displayed in a second user interface region. In response to detecting a second input, in accordance with a determination that the second input corresponds to a request to manipulate the virtual object in the second user interface region, a display property of the virtual object is changed, and in accordance with a determination that the second input corresponds to a request to display the virtual object in an augmented reality environment, the virtual object is displayed with a representation of a field of view of the one or more cameras.
