Abstract

Enhanced visibility of icons and other types of menu items is provided by increasing size and or skew or both of one or more icons or menu items in a generally inverse relation to proximity of a cursor image address to particular icons or menu items. Increase of size enhances user recognition of an ordinarily small menu item or icon and simultaneously provides the effect of stabilizing cursor position during selection without affecting linearity of response to a graphic input device. Skew and repeated expansion may be used to attract user attention while repeated expansion simplifies icon manipulation by the user in determining a response to a mandatory input demand from an application.

Claims

1. A method for enhancing a visual feature of a display of a menu item in an inverse relation to a distance between the menu item and a cursor image, including the steps of:

establishing a location of said menu item on a display;

detecting a location of the cursor image on the display;

detecting a distance between said location of said menu item and said location of said cursor image;

assigning a value to an attribute data representing said visual feature, said assigned value being from a group of at least three different values, said assigned value being in a generally inverse relation to said detected distance;

displaying a menu item in accordance with said attribute data value assigned by said assigning step, so that the visual feature of the displayed menu item corresponding to said attribute is displayed in a manner selected from a group of at least three manners, each of said at least three manners corresponding to one of said group of at least three different values.

2. A method as recited in claim 1, wherein said attribute includes size.

3. A method as recited in claim 1, wherein said attribute includes skew.

4. A method as recited in claim 2, wherein said attribute includes skew.

5. A method as recited in claim 2, including the further step of

detecting presence of said cursor location within a selection zone of said menu item.

6. A method as recited in claim 5, including the further step of

limiting size of said menu item in response to said step of detection of said cursor location within said detection zone of said menu item.

7. A method as recited in claim 6, wherein said detecting and limiting steps are repeated.

8. A method as recited in claim 1, including the further steps of

comparing distance of at least two menu items to said location of said cursor, and

performing said displaying step only on a menu item determined to be closest to said cursor image by said comparing step.

9. A method as recited in claim 1, including the further steps of

comparing distance of at least two menu items to said location of said cursor, and

performing said displaying step only on menu items determined to be closer to said cursor image by said comparing step than a threshold distance.

10. A method as recited in claim 1, including the further step of

altering said cursor image location,

repeating said step of determining distance between said location of said at least one of said menu items and said location of said cursor image, and

displaying another menu item in accordance with an attribute determined in generally inverse relation to said distance determined by said determining step.

11. A method as recited in claim 10, wherein said altering step is performed in response to a graphic input device.

12. A method as recited in claim 11, wherein said graphic input device is a mouse.

13. A method as recited in claim 10, including the further steps of

comparing distance of at least two menu items to said location of said cursor, and

performing said displaying step only on a menu item determined to be closest to said cursor image by said comparing step.

14. A method as recited in claim 10, including the further steps of

comparing distance of at least two menu items to said location of said cursor, and

performing said displaying step only on menu items determined to be closer to said cursor image by said comparing step than a threshold distance.

15. A method as recited in claim 1, including the further steps of

detecting a cursor location within a selection zone of a menu item, and

controlling selection of said menu item.

16. A method as recited in claim 1, including the further step of

altering a selection zone of said at least one menu item in generally inverse proportion to said distance determined in said determining step.

17. A method as recited in claim 16, including the further steps of

detecting a cursor location within said selection zone of a menu item, and

controlling selection of said menu item.
