Abstract: A computer system displays a user interface that includes a first region and a second region separated by a third region and displays a focus indicator within the first region. In response to detecting an input to move the focus indicator relative to the user interface, the input being associated with movement toward the second region, if the input meets respective criteria based on the movement associated with the input, the computer system moves the focus indicator from the first region to the second region in accordance with the movement associated with the input without displaying the focus indicator in the third region; and, if the input does not meet the respective criteria, the computer system changes an appearance of the focus indicator in accordance with the movement associated with the input while continuing to display at least a portion of the focus indicator within the first region.

Abstract: A computer system displays a first application user interface at a first location in a three-dimensional environment. While displaying the first application user interface at the first location in the three-dimensional environment, the computer system detects, at a first time, a first input corresponding to a request to close the first application user interface. In response to detecting the first input corresponding to a request to close the first application user interface: the computer system closes the first application user interface, including ceasing to display the first application user interface in the three-dimensional environment; and, in accordance with a determination that respective criteria are met, the computer system displays a home menu user interface at a respective home menu position that is determined based on the first location of the first application user interface in the three-dimensional environment.

Abstract: While displaying an application user interface, in response to detecting a first input to an input device a computer system, in accordance with a determination that the application user interface is in a first mode of display, wherein the first mode of display includes an immersive mode in which only content of the application user interface is displayed, displays via the display generation component the application user interface in a second mode of display, wherein the second mode of display includes a non-immersive mode in which respective content of the application user interface and other content are concurrently displayed, and in accordance with a determination that the application user interface is in the second mode of display, the computer system replaces display of at least a portion of the application user interface by displaying a home menu user interface via the display generation component.

Abstract: In some embodiments, a computer system displays a virtual surface for containing one or more virtual objects in a three-dimensional environment. In some embodiments, a computer system automatically resizes virtual surfaces that contain objects. In some embodiments, a computer system displays feedback related to removal and/or addition of objects to virtual surfaces.

Abstract: A computer system displays a first user interface object and a first control element with a first appearance that is associated with performing a first operation with respect to the first user interface object, in a first view of a three-dimensional environment. The computer system detects a first gaze input that is directed to the first control element, and in response, updates an appearance of the first control element from to a second appearance that is different from the first appearance. While displaying the first control element with the second appearance, the computer system detects a first user input directed to the first control element, and in accordance with a determination that the first user input meets first criteria, updates the appearance of the first control element from the second appearance to a third appearance that is different from the first appearance and the second appearance.

Abstract: A computer system detects a gaze input directed to a region in an environment and, while detecting the gaze input, detects a touch input. In response, the computer system displays a focus indicator at a location corresponding to the region. The computer system detects a continuation of the touch input that includes movement of the touch input along an input surface while being maintained on the input surface. In response, the computer system moves the focus indicator in accordance with the movement of the touch input: within a user interface of an application, if the movement corresponds to a request to move the focus indicator within the user interface; and within the user interface without moving the focus indicator outside of the boundary of the user interface, if the movement corresponds to a request to move the focus indicator outside of a boundary of the user interface.

Abstract: A computer system, in response to detecting a first input on a rotatable input mechanism, in accordance with a determination that the first input is a first type of input: changes an immersion level associated with display of an extended reality (XR) environment generated by the display generation component to a first immersion level in which display of the XR environment concurrently includes virtual content from an application and a passthrough portion of a physical environment of the computer system. In accordance with a determination that the first input is a second type of input: the computer system performs an operation different from changing the immersion level associated with display of the XR environment.

Abstract: A computer system displays a first and second user interface object in a three-dimensional environment. The first and second user interface objects have a first and second spatial relationship to a first and second anchor position corresponding to a location of a user's hand in a physical environment, respectively. While displaying the first and second user interface objects in the three-dimensional environment, the computer system detects movement of the user's hand in the physical environment, corresponding to a translational movement and a rotational movement of the user's hand relative to a viewpoint, and in response, translates the first and second user interface objects relative to the viewpoint in accordance with the translational movement of the user's hand, and rotates the first user interface object relative to the viewpoint in accordance with the rotational movement of the user's hand without rotating the second user interface object.

Abstract: A display case for receiving a transmitter module and retaining the module in place is used in a security system which detects and monitors fire, burglary, emergencies, appliance failure and the like. Transmitter modules, which are placed at each of the sensors, transmit information to a central monitor. The display case for receiving the transmitter module is designed to present the module in open view so that the user can readily discern that the transmitter is in place. The display case cover includes provision to expose the transmitter while engaging the transmitter body to hold it in place in the display case.

Abstract: An enzyme composition comprising a D-2-haloalkanoic acid halidohydrolase, bacteria containing said enzyme, a process for the preparation of said enzyme as a cell-free composition and a process in which the enzyme is used to increase the concentration of the L-enantiomer in a mixture of the D- and L-enantiomers of a 2-haloalkanoic acid. Preferably the 2-haloalkanoic acid is 2-bromo- or 2-chloro-propionic acid and the process for increasing the concentration is carried out under anaerobic conditions.
