9. The device of claim 4 , wherein identifying one of the candidate selectable objects as the target selectable object includes selecting a respective candidate selectable object that is closest to the termination point as the target selectable object.

10. A method comprising:

at a computing device with one or more processors and memory, wherein the device is in communication with a display and a touch-sensitive surface:

sending instructions to the display for displaying at least a portion of a user interface, the user interface having one or more selectable objects;

receiving an input that corresponds to a first gesture detected on the touch-sensitive surface, wherein the first gesture includes lateral movement of a respective contact on the touch-sensitive surface and liftoff of the respective contact from the touch-sensitive surface;

sending instructions to the display for displaying an object selection indicator; and

in response to receiving at least a portion of the input that corresponds to the first gesture:

moving the object selection indicator in accordance with the first gesture while the respective contact is detected on the touch-sensitive surface;

after detecting liftoff of the respective contact from the touch-sensitive surface,

determining a termination point of movement of the object selection indicator based on the first gesture;

searching for a target selectable object; and

sending instructions to the display for moving the object selection indicator, wherein:

when a target selectable object is identified, moving the object selection indicator includes continuing to move the object selection indicator towards the target selectable object after detecting liftoff of the respective contact from the touch-sensitive surface, wherein the target selectable object is at a location that is different than a location of the termination point; and

when a target selectable object is not identified, moving the object selection indicator includes continuing to move the object selection indicator towards the termination point after detecting liftoff of the respective contact from the touch-sensitive surface.

11. The method of claim 10 , wherein searching for the target selectable object includes:

calculating a trajectory of the object selection indicator based on the first gesture, wherein the termination point corresponds to an end of the trajectory;

searching for one or more candidate selectable objects that meet predefined candidate criteria; and

when one or more candidate selectable objects are found, identifying a respective candidate selectable object as the target selectable object.

12. The method of claim 11 , wherein the respective candidate selectable object is identified as the target selectable object based on proximity of the respective candidate selectable object to the termination point.

13. The method of claim 11 , wherein, when no candidate selectable objects are found, sending instructions to the display for moving the object selection indicator in accordance with the first gesture includes sending instructions to the display for moving the object selection indicator to the termination point.

14. The method of claim 11 , wherein the trajectory is calculated based on simulated physical properties of the object selection indicator.

15. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a computing device that is in communication with a display and a touch-sensitive surface, cause the device to:
