Abstract

A computer system and method of performing a second chance pointer operation wherein a pointer displayed on a computer display includes at least one alternate hot spot. In response to a pointer event, such as a mouse click, with a default hot spot not overlaying a graphical display element, or graphical user interface (GUI) object (e.g., icon, hypertext link, window tool bar), the object may nonetheless be selected if another hot spot on the pointer overlays the object, e.g., by resignaling the pointer event with the alternate hot spot. Advantageously, the resignaling of the pointer event may include selecting the overlaid GUI object, and/or providing feedback to the user regarding the alternate hot spots.

Claims

1. A method of selecting a graphical display element displayed on a computer display using a user-manipulated pointing device, comprising:

in response to a user selection operation initiated by a user, determining whether a first coordinate associated with the user-manipulated pointing device is disposed within an input region of the graphical display element;

in response to determining that the first coordinate is not within the input region, selecting the graphical display element if a second coordinate associated with the user-manipulated pointing device is disposed within the input region; and

displaying feedback to the user if the second coordinate associated with the user-manipulated pointing device is disposed within the input region, wherein displaying feedback includes repositioning a pointer associated with the user-manipulated pointing device to correspond with the second coordinate.

2. The method of claim 1, wherein selecting the graphical display element further comprises referencing a pointer identification control table, associated with the user-manipulated pointing device, for the second coordinate.

4. The method of claim 1, wherein determining whether the first coordinate is disposed within the input region is performed responsive to a first pointer event, and wherein selecting the graphical display element includes resignaling a second pointer event at the second coordinate.

3. A method of selecting a graphical display element displayed on a computer display using a user-manipulated pointing device, comprising:

in response to a user selection operation initiated by a user, determining whether a first coordinate associated with the user-manipulated pointing device is disposed within an input region of the graphical display element;

in response to determining that the first coordinate is not within the input region, selecting the graphical display element if a second coordinate associated with the user-manipulated pointing device is disposed within the input region; and

displaying feedback to the user if the second coordinate associated with the user-manipulated pointing device is disposed within the input region, wherein displaying feedback includes altering the display of a pointer associated with the user-manipulated pointing device to indicate the second coordinate.

5. A method of controlling a computer system with a pointing device coupled to a pointer on a computer display, the pointing device adapted to input a pointer event at a first coordinate position relative to the pointer, the method comprising:

in response to a first pointer event, determining whether the first coordinate position relative to the pointer overlays an input region of a graphical display element, wherein determining whether the first coordinate position relative to the pointer overlays a graphical display element further includes;

determining whether the first coordinate position is within one of an active window and an inactive window;

in response to the first coordinate position being within the active window, sending the pointer event to the active window; and

in response to the first coordinate position being within the inactive window, performing an inactive window pointer event action; and

if not, generating a second pointer event at a second coordinate position relative to the pointer.

6. The method of claim 5, wherein generating the second pointer event is performed by a default event handler.

7. The method of claim 5, wherein performing the inactive window pointer event action includes focusing by setting the inactive window as an active window.

8. The method of claim 5, wherein generating the second pointer event at the second coordinate position relative to the pointer includes accessing a pointer information control table to locate relative positioning for the second coordinate position.

9. The method of claim 5, wherein determining whether the first coordinate position relative to the pointer overlays the input region of the graphical display element comprises:

referencing a pointer event record including a selected coordinate pointer and the second coordinate position; and

determining that the selected coordinate pointer corresponds to the first coordinate position.

10. The method of claim 9, wherein generating the second pointer event at the second coordinate position relative to the pointer comprises:

changing the selected coordinate pointer to correspond to the second coordinate position; and

resignaling the pointer event record including the changed selected coordinate pointer.

11. An apparatus configured to select a graphical display element with a pointer displayed on a computer display using a user-manipulated pointing device, comprising:

(a) a memory; and

(b) a program, resident in the memory, the program configured, in response to a user selection operation initiated by a user, to determine whether a first coordinate associated with the pointer is disposed within an input region of the graphical display element, and, in response to determining that the first coordinate is not within the input region, to perform a second chance pointer operation, wherein the program is further configured to identify a plurality of prioritized coordinates associated with the user-manipulated pointing device, and to perform the second chance pointer operation at a second coordinate comprising the highest priority one of the prioritized coordinates disposed within the input region the second chance pointer operation including at least one of repositioning the pointer to correspond to the second coordinate and altering the display of the pointer to indicate the second coordinate.

12. The apparatus of claim 11, wherein the user selection operation comprises positioning the pointer using the user-manipulated pointing device, and wherein the program is configured to perform the second chance pointer operation by providing feedback at the second coordinate of the pointer in response to the second coordinate being disposed within the input region.

13. The apparatus of claim 11, wherein the program is configured, in response to the second coordinate being disposed within the input region, to perform the second chance pointer operation by selecting the graphical display element.

14. The apparatus of claim 11, wherein the user selection operation includes a first pointer event at the first coordinate, and wherein the program is further configured to perform the second chance pointer operation by resignaling a second pointer event at the second coordinate.

15. The apparatus of claim 14, further including a pointer event record, resident in memory, defining the first pointer event including a location on the computer display, and wherein the program is configured to resignal the second pointer event by changing the location in the pointer event record from the first coordinate to the second coordinate of the pointer.

16. The apparatus of claim 11, wherein the user selection operation includes a pointer event, and wherein the program is further configured to perform the second chance pointer operation by providing feedback to the user in response to the pointer event.

19. The apparatus of claim 11, further including a pointer identification control table, resident in memory, the table configured to associate the first and second coordinates with the user-manipulated pointing device, and wherein the program is further configured to read the first and second coordinates of the table.

20. The apparatus of claim 11, further including a default event handler, resident in memory, configured to perform the second chance pointer operation at the second coordinate.
