Abstract: An electronic device provides, to a display, data to present a user interface that includes a first group of user interface objects and a second group of user interface objects. A current focus is on a first user interface object of the first group of user interface objects. The device receives an input that corresponds to a request to move the current focus to a user interface object in the second group of user interface objects; determines a projection of the first user interface object based on a direction of the input; identifies one or more user interface objects that overlap with the projection of the first user interface object in the direction on the display that corresponds to the direction of the input; and moves the current focus to a second user interface object of the one or more identified user input objects.

Abstract: An electronic device provides, to a display, data to present a user interface that includes: a plurality of user interface objects, and a current focus on a first user interface object. The device receives an input that corresponds to a gesture detected on a touch-sensitive surface of a user input device. The gesture includes a movement of a contact across the touch-sensitive surface followed by a lift-off of the contact from the touch-sensitive surface. The gesture includes a characteristic movement distance and a characteristic movement speed. In accordance with a determination that the gesture satisfies coasting criteria, the device moves the current focus in the user interface; and decelerates movement of the current focus across the series of user interface objects at a first deceleration rate that is based on: the characteristic movement distance of the gesture, and the characteristic movement speed of the gesture.

Abstract: An electronic device provides, to a display, data to present a user interface with a plurality of user interface objects, and a current focus is on a first user interface object. The device receives an input corresponding to movement of a contact across a touch-sensitive surface. The movement includes first and second components each corresponding to first and second axes on the display. The device moves the current focus, along the first and second axes by amounts based on magnitudes of the first and second components. The amount of movement of the current focus along a non-dominant axis is reduced relative to the amount of movement of the current focus along a dominant axis by a scaling factor that is based on a rate of movement of the contact.
