Abstract: A device that includes one or more processors may determine a configuration of a display region of the device. The device may also receive a request to perform an animation of a virtual object within the display region. The request may be indicative of a given duration for the animation based on the animation being performed within a given display region having a given configuration. The device may also modify the given duration to determine an adjusted duration for the animation based on a comparison between the configuration and the given configuration. The device may also perform the animation within the display region based on the animation having the adjusted duration.

Abstract: While a computing device is in a limited-access state, the computing device may output for display a user interface element. Responsive to the computing device receiving an indication of a first user input at a region of a presence-sensitive input device that corresponds to at least a portion of the user interface element as displayed, the computing device may alter the visual appearance of the user interface element to indicate that the user interface element is selected. Responsive to the computing device determining that it has received the indication of the second user input at the region of the presence-sensitive input device within the predefined period of time subsequent to receiving the indication of the first user input, the computing device may activate the user interface element.

Abstract: A computing device is described that, while presenting a graphical user interface (GUI) associated with a first application, transitions from a first operational state to a second operational state. While in the second operational state, the computing device stops presenting the GUI associated with the first application, determines a context of the computing device, and receives a notification associated with a second application.
