Abstract: In an embodiment, a device may include an attention detection service. The attention detection service may monitor various peripheral devices in the device for indications that a user is paying attention to the device. Various clients may register for notification of attention detection and attention lost (attention no longer detected) events, or may poll the service for the events. If a user is not paying attention to the device, it may be possible to take various actions to permit reduced energy consumption.

Abstract: Systems and methods are disclosed for implementing an educational mode on a portable computing device, such as a tablet computer, that is a single-user system, used serially by multiple users. Each user can have a separate user storage that may be encrypted. The computing device boots as a system user to a login screen. A first student user enters user credentials into the login screen. The computing device can reboot the user-space processes, while leaving the kernel running, rebooting the computing device as the first student user. When the first student user logs out, data to be synchronized to, e.g., the cloud, can be synchronized for the first student user while a second student user is logged into the device.

Abstract: A method of providing navigation instructions in a locked mode of a device is disclosed. The method, while the display screen of the device is turned off, determines that the device is near a navigation point. The method turns on the display screen and provides navigation instructions. In some embodiments, the method identifies the ambient light level around the device and turns on the display at brightness level determined by the identified ambient light level. The method turns off the display after the navigation point is passed.

Abstract: A method is performed at an electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts. The method includes displaying, on the display, a user interface for an application; detecting an edge input that includes detecting a change in a characteristic intensity of a contact proximate to an edge of the touch-sensitive surface; and, in response to detecting the edge input: in accordance with a determination that the edge input meets system-gesture criteria, performing an operation that is independent of the application, wherein: the system-gesture criteria include intensity criteria; the system-gesture criteria include a location criterion that is met when the intensity criteria for the contact are met while the contact is within a first region relative to the touch-sensitive surface; and the first region relative to the touch-sensitive surface is determined based on one or more characteristics of the contact.

Abstract: An electronic device displays a plurality of user interface representations in a stack on a display. The device detects a first drag gesture by a first contact at a location on a touch-sensitive surface that corresponds to a location of a first user interface representation on the display. While the first contact is at a location on the touch-sensitive surface that corresponds to the location of the first user interface representation on the display and is moving across the touch-sensitive surface in a direction that corresponds to a first direction on the display, the device moves the first user interface representation in the first direction on the display at a first speed in accordance with a speed of the first contact on the touch-sensitive surface and moves a second user interface representation, disposed above the first user interface representation in the stack, in the first direction at a second speed greater than the first speed.

Abstract: A method includes: displaying a first view of a first application; detecting a first portion of a first input; if the first portion of the first input meets application-switching criteria, concurrently displaying portions of the first application view and a second application view; while concurrently displaying the portions of the application views, detecting a second portion of the first input; if the second portion of the first input meets first-view display criteria (liftoff of contact detected in a first region), ceasing to display the portion of the second application view and displaying the first application view; and if the second portion of the first input meets multi-view display criteria (liftoff of contact detected in a second region), maintaining concurrent display of a portion of the first application view and a portion of the second application view on the display after detecting the liftoff of the contact.
