Abstract: An example method is performed at a device with a display and a biometric sensor. While the device is in a locked state, the method includes displaying a log-in user interface that is associated with logging in to a first and second user account. While displaying the log-in user interface, the method includes, receiving biometric information, and in response to receiving the biometric information: when the biometric information is consistent with biometric information for the first user account and the first user account does not have an active session, displaying a prompt to input a log-in credential for the first user account; and when the biometric information is consistent with biometric information for the second user account and the second user account does not have an active session on the device, displaying a prompt to input a log-in credential for the second user account.

Abstract: In some embodiments, an electronic device dynamically assigns functionalities to one or more buttons depending on an orientation associated with the device.

Abstract: In an embodiment, a system implements detent operation using tactile and audio effects that give the user the effect of a detent without including the mechanical devices that detents would normally imply. The detent operation may be implemented in software and may be synchronized to events on the display of the system (e.g. animation events), which may provide a convincing user experience. A low latency path from the applications and user interface program of the system to the hardware that implements the detent operation may be provided to help ensure that the synchronization of animation events and detent operations is maintained.

Abstract: A method is performed at a computing system including: a first housing that includes a primary display, and a second housing at least partially containing (i) a physical keyboard and (ii) a touch-sensitive secondary display (TSSD) distinct from the primary display. The method includes: receiving a request to open a file associated with a content-editing application. The method further includes, in response to receiving the request: displaying, on the primary display, content from the file within the content-editing application; and also displaying, on the TSSD, a user interface including multiple user interface elements each associated with a content-display parameter for modifying presentation of content within the content-editing application.

Abstract: An example method is performed at a computing system with: a first housing that includes a primary display, and a second housing at least partially containing (i) a physical keyboard and (ii) a touch-sensitive secondary display (TSSD) that is distinct from the primary display. The example method includes: displaying, on the primary display, a user interface. The example method also includes, detecting an input directed to a user interface element in the user interface displayed on the primary display, and the input includes movement. In response to detecting the movement, the method further includes: moving the user interface element towards the TSSD; ceasing to display the respective portion of the user interface on the primary display; and displaying, on the TSSD that is integrated into the second housing that contains the physical keyboard, a representation of the user interface element that was previously displayed on the primary display.

Abstract: Disclosed herein are systems, devices, and methods for dynamically updating a touch-sensitive secondary display. An example method includes receiving a request to open an application and, in response, (i) displaying, on a primary display, a plurality of user interface (UI) objects associated with the application, the plurality including a first UI object displayed with associated content and other UI objects displayed without associated content; and (ii) displaying, on the touch-sensitive secondary display, a set of affordances representing the plurality of UI objects. The method also includes: detecting, via the touch-sensitive secondary display, a swipe gesture in a direction from a first affordance and towards a second affordance, the first affordance representing the first UI object and the second affordance represents a distinct second UI object. In response to detecting the swipe gesture, the method includes: updating the primary display to display associated content for the second UI object.
