Abstract
A method for operating a user interface on a system in which objects are displayed on a touch sensitive display screen. A touch coordinate is received from the touch sensitive display screen indicative of a touch location on the display screen. A search area surrounding the touch coordinate is searched for an object. The search area has an initial minimum size. If an object is found within the initial minimum search area it is identified. If no object is found, then the size of the search area is incrementally increased and searched until a final maximum size is reached. If no object is found, then the search is terminated.
Claims12
A method for selecting an object on a display screen, the method comprising:
- receiving a touch coordinate indicative of a touch location on the display screen;
- searching for an object within a search area surrounding the coordinate, wherein the search area has an initial size;
- identifying an object found within the search area;
- and
- incrementally increasing the size of the search area if no object is found within the search area until a final maximum size is reached.
A system comprising:
- a touch sensitive display screen;
- an instruction processor coupled to a memory, wherein the instruction processor is controllably coupled to the touch sensitive screen, wherein the instruction processor is operable to execute instructions that cause a method for operating a user interface on the touch sensitive display screen to be performed, the method comprising:
- displaying objects on the display screen;
- receiving a touch coordinate indicative of a touch location on the display screen;
- searching for an object within a search area surrounding the coordinate, wherein the search area has an initial size;
- identifying an object found within the search area;
- and
- incrementally increasing the size of the search area if no object is found within the search area until a final maximum size is reached.
A non-transitory computer-readable medium storing software instructions that, when executed by a processor, cause a method for operating a user interface on a system to be performed, the method comprising:
- displaying objects on a display screen;
- receiving a touch coordinate indicative of a touch location on the display screen;
- searching for an object within a search area surrounding the coordinate, wherein the search area has an initial size;
- identifying an object found within the search area;
- and
- incrementally increasing the size of the search area if no object is found within the search area until a final maximum size is reached.
