Device, method, and graphical user interface for interacting with three-dimensional environment

The present disclosure relates to devices, methods, and graphical user interfaces for interacting with a three-dimensional environment. A computer system receives biometric data corresponding to a first user while displaying a first computer-generated experience at a first level of immersion. In response to receiving the biometric data: in accordance with a determination that the biometric data corresponding to the first user satisfies a first criterion, the computer system displays a first computer-generated experience at a second immersion level, wherein the first computer-generated experience displayed at the second immersion level occupies a greater portion of the field of view of the first user than the first computer-generated experience displayed at the first immersion level; and in accordance with a determination that the biometric data corresponding to the first user does not meet the first criteria, the computer system continues to display the first computer-generated experience at the first immersi
