Abstract: Various implementations disclosed herein include devices, systems, and methods that generate a depiction of a portion of a physical environment illuminated based on light provided by identified portions of a virtual light source. For example, an example process may include obtaining sensor data, generating a three-dimensional (3D) reconstruction based on the sensor data, positioning a virtual light source relative to the 3D reconstruction, identifying a portion of the virtual light source based on unobstructed paths between the portion of the physical environment and the virtual light source, associating the portion of the virtual light source with the portion of the physical environment, and generating a view that includes a depiction of a portion of a physical environment illuminated based on light provided by the identified portions of the virtual light source.

Abstract: The present disclosure generally relates to methods and user interfaces for providing clock user interfaces. In some embodiments, methods and user interfaces for providing clock user interfaces displaying simulated emitted light, methods and user interfaces for displaying clock user interfaces including astronomical object, methods and user interfaces for displaying clock user interfaces that include adjustable time indications, methods and user interfaces for displaying clock user interfaces that include multiple calendar systems, methods and user interfaces for displaying clock user interfaces including animated numerals, methods and user interfaces for displaying clock user interfaces with colors that are based on a selected color, and/or methods and user interfaces for displaying clock user interfaces including animated lines are described.

Abstract: A method of unlocking a second device using a first device is disclosed. The method can include: the first device pairing with the second device; establishing a trusted relationship with the second device; authenticating the first device using a device key; receiving a secret key from the second device; receiving a user input from an input/output device; and transmitting the received secret key to the second device to unlock the second device in response to receiving the user input, wherein establishing a trusted relationship with the second device comprises using a key generated from a hardware key associated with the first device to authenticate the device key.

Abstract: A novel method for out-of-band key verification that improves on both the usability and the security of the numeric-code method is provided. The method use portions of the generated keys as inputs to perform procedural image generation to produce a visualization at each of the two devices that the user can visually compare and confirm. This visualization can be a static image or a motion animation. The method can uses more of the key data to generate visualizations with more features to reduce the likelihood of false matches. The method can also use less key data to allow for quicker comparison and confirmation.
