Abstract

In a graphics system for a graphical user interface in which a plurality of screen objects are displayed, a method of targeting a screen object comprises determining a screen object targeted by a pointer and reading a pointer selection and selecting a targeted scream object. The method being characterized by generating, according to the proximity of the pointer position to a screen object, a weighting associated with each screen object, the weighting being in inverse proportion to the displayed size of the associated screen object; and wherein the determination is adapted to determine the targeted screen object according to the respective weightings associated with the scream objects.

Claims

1. A graphics system for a graphical user interface in which a plurality of screen objects are displayed comprising:

targeting means comprising means for determining a screen object targeted by a pointer;

selection means comprising means for reading a pointer selection and means for selecting a targeted screen object;

said graphics system being characterized by;

said targeting means comprising means for generating, according to the proximity of the pointer position to a screen object, a weighting associated with each screen object, said weighting being in inverse proportion to the displayed size of the associated screen object, and wherein said determining means is adapted to determine said targeted screen object according to the respective weightings associated with said screen objects.

2. The graphics system as claimed in claim 1, wherein the targeting means is only responsive to said pointer selection to determine the targeted screen object.

3. The graphics system as claimed in claim 1, wherein the targeting means is responsive to each pointer position movement to determine the targeted screen object and wherein said graphics system is adapted to highlight said targeted screen object.

4. The graphics system as claimed in claim 1, wherein said determining means is adapted to determine a screen object is targeted only if a maximum object weighting exceeds a pre-determined threshold.

5. The graphics system as claimed in claim 1, wherein said weighting is limited by a maximum growth factor.

6. The graphics system as claimed in claim 5, wherein a control panel is associated with said graphics system, said control panel being responsive to user interaction and to update said maximum growth factor.

7. The graphics system of claim 1, embodied in an operating system.

8. The graphics system of claim 1, wherein an application which includes said graphics system is one of a general purpose application or a dedicated application.

9. A computer program product comprising computer program code stored on a computer readable storage medium for, when executed on a computing device, controlling the targeting of screen objects, the program code comprising the graphical system of claim 1.

10. In a graphics system for a graphical user interface in which a plurality of screen objects are displayed, a method of targeting a screen object comprising the steps of:

determining a screen object targeted by a pointer;

reading a pointer selection and selecting a targeted screen object;

said method being characterized by;

generating, according to the proximity of the pointer position to a screen object, a weighting associated with each screen object, said weighting being in inverse proportion to the displayed size of the associated screen object; and

wherein said determining step is adapted to determine said targeted screen object according to the respective weightings associated with said screen objects.
