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: A system and method for conformal alignment of an aircraft-based head worn display (HWD) system defines far-field features in view of the HWD display, each far-field feature having a 3D truth position in a navigational reference frame. The aircraft GPS/IRS determines pointing vectors to each feature in the aircraft reference frame. The HWD user estimates a nominal head pose for orienting the far-field features in the HWD display, and the HWD system renders the far-field features based on the nominal head pose and pointing vectors. The rendered far-field features are aligned to their real-world 3D truth positions (either manually or with the assistance of witness cameras) and a latched pose of the HWD headtracker system determined based on a successful alignment within accuracy bounds. Based on the latched headtracker pose, the HWD headtracker alignment and the alignment of the HWD display reference frame to the aircraft reference frame are updated.

Abstract: An electronic device having a camera, while displaying a live preview for the camera, detects activation of a shutter button at a first time. In response, the electronic device acquires, by the camera, a representative image that represents a first sequence of images, and a plurality of images after acquiring the representative image, and also displays an indication in the live preview that the camera is capturing images for the first sequence of images. The electronic device groups images acquired by the camera in temporal proximity to the activation of the shutter button at the first time into the first sequence of images, such that the first sequence of images includes a plurality of images acquired by the camera prior to detecting activation of the shutter button at the first time, the representative image, and the plurality of images acquired by the camera after acquiring the representative image.

Abstract: An electronic device provides, to a display, while in a screensaver mode, data to present a first media, that includes a first visual motion effect. In response to receiving a user input on a remote user input device, a type of the user input on the remote user input device is determined. If the user input is of a first type, the device provides, to the display, data to present the first media, that includes the first visual motion effect, with corresponding descriptive text. If the user input is of a second type, the device exits the screensaver mode.
