Abstract: A system may include electronic devices that communicate wirelessly. When positioned so that a pair of devices overlap or are adjacent to one another, the devices may operate in a linked mode. During linked operations, devices may communicate wirelessly while input gathering and content displaying operations are shared among the devices. One or both of a pair of devices may have sensors. A capacitive sensor or other sensor may be used to measure the relative position between two devices when the two devices overlap each other. Content displaying operations and other linked mode operations may be performed based on the measured relative position between the two devices and other information.

Abstract: An electronic device may be provided with control circuitry for locating lost items. The control circuitry may determine where an item is located and may use the display or other output device to guide a user to the item. The display may display a visual guide such as an arrow, a sphere, a circle, a compass, or other visual aid that points the user in the direction of the item. The control circuitry may change the size or other characteristic of the visual aid on the display as the distance between the electronic device and the object changes. The control circuitry may change the location of the visual aid on the display as the orientation of the electronic device relative to the object changes. The display may overlay the visual aid onto live images of the user's surroundings as they are captured by a camera.

Abstract: A computing system comprises one or more processors, memory, a first housing that includes a primary display, and a second housing at least partially containing a physical keyboard and a touch-sensitive secondary display that is distinct from the primary display. The computing system displays a first user interface on the primary display, the first user interface includes one or more user interface elements. The computing system identifies, from the one or more user interface elements, an active user interface element that is in focus on the primary display. The computer system, in accordance with a determination that the active user interface element that is in focus on the primary display is associated with the application executed by the computing system, displays, on the touch-sensitive secondary display, a second user interface that includes a first set of one or more affordances corresponding to the application.

Abstract: An electronic device includes a first display portion, a second display portion, and a hinge connecting the first display portion to the second display portion. The electronic device displays, on the first display portion, a calendar application. The electronic device receives a request to display information about a first event that is associated with the calendar application. The electronic device, in response to receiving the request, displays on the first display portion event details for the first event. The event details include a start time and an end time for the first event. The electronic device displays, on the second display portion, an affordance for navigating the calendar application. The affordance indicates a range of time that at least includes the start time and the end time.

Abstract: A physical keyboard can be used to collect user input in a typing mode or in a tracking mode. To use a tracking mode, first movement data is detected for a hand of a user in relation to a physical keyboard at a first location. A determination is made that the first movement data is associated with a tracking movement. In response to determining that the movement type is associated with the tracking movement, a tracking mode is initiated. User input is provided based on the movement data and in accordance with the tracking mode. Contact data and non-contact data is used to determine a user intent, and a user instruction is processed based on the user intent.

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: An electronic device may use information about the location of nearby devices to make sharing with those devices more intuitive for a user. When two devices are pointed towards one another, each device may automatically present the option to share information with the other device. When a user wishes to share information with one or more devices in a group of users, an array of icons representing the nearby users may be positioned on the display according to the locations of the nearby users so that the sharing user can easily select which user he or she wishes to share with. A sharing user may broadcast a signal and nearby users may elect to receive the signal by pointing their devices towards the sharing user. A user of two devices may share information between the two devices and may use one device to manipulate the information on the other device.
