Devices, Methods, and Graphical User Interfaces for Displaying Applications in Three-Dimensional Environments

A computer system displays a first view of a user interface of a first application with a first size at a first position corresponding to a location of at least a portion of a palm that is currently facing a viewpoint corresponding to a view of a three-dimensional environment provided via a display generation component. While displaying the first view, the computer system detects a first input that corresponds to a request to transfer display of the first application from the palm to a first surface that is within a first proximity of the viewpoint. In response to detecting the first input, the computer system displays a second view of the user interface of the first application with a second size and an orientation that corresponds to the first surface at a second position defined by the first surface.
