Patent ID: 10241760

Abstract:
Disclosed are touch sensitive devices and methods of responding to hits in touch sensitive devices that include a graphical user interface having interface elements, each associated with a program element. A hit test map updater is used to process graphical user interface information into a hit test map in connection with the rendering of the graphical user interface, such that the hit test map associates properties with interface elements appearing on the graphical user interface. An input processor is used to receive a location corresponding to an input in connection with an input event, search the hit test map in which values are associated with interface elements appearing in the graphical user interface, and identify a property of the interface element from the values. In an embodiment, the identified property is proved to a central processing system and a user interface event is generated. In an embodiment, the properties received from the hit test map updater and the input processor are used to determine a program element associated with the property, and the program element is signaled. In an embodiment, the identified property is processed to determine a change to the graphical user interface, and the change is displayed.
