Abstract
The described embodiments allow for the association of an interaction with a target in a display. One embodiment includes detecting an interaction with an area associated with a graphical element in a display, detecting a later interaction displaced from the area, and associating the later interaction with a target in the display based at least on the time between the interaction with the area and the later interaction. User interactions with one or more displayed hit targets are based on corresponding time-varying hit zones. In response to unlimited user interaction with a hit target, subsequent user selections are validated based on a time-varying hit zone that is typically extended with respect to the previously selected hit target. The extended selection zone can overlap one or more other hit targets to favor re-selection of the individually selected hit target. The extended selection zone generally decreases as a function of time from prior selections of a hit zone.
