Abstract

A method and computer program capable of providing a plurality of activation areas in a display, the display having a plurality of selectable objects surrounded by an object area which defines the boundaries of the selectable objects which must be contacted by a pointing device for selection. The activation areas surround the selectable objects and expand the boundary of the selectable objects which must be contacted by the pointing device for selection. The size of the activation areas is determined by an expansion boundary having a border that outlines the size and shape of the activation areas and enlarges the activation areas to a maximum size without overlapping.

Claims

1. A method for selecting a selectable object defined by an object area in a display with a pointing device, the method comprising the steps of:

providing a plurality of selectable objects in a display, said selectable objects surrounded by an object area which defines the boundaries of said selectable objects which must be contacted by said pointing device for selection;

providing a plurality of activation areas in the display, the activation areas surrounding the selectable objects in the display and being greater than the object area, said activation areas expanding the boundary of said selectable objects which must be contacted by said pointing device for selection;

providing an expansion boundary, said expansion boundary having a border that outlines the size and shape of the activation areas, said border determined in accordance with properties of the selectable objects and of the display; and

enlarging the plurality of activation areas to maximum activation areas without overlapping any one activation area with any other activation area.

2. A method according to claim 1 further comprising the step of performing a selection operation in the activation areas to select the selectable objects.

3. A method according to claim 2, wherein the selection operation changes the appearance of the selectable objects.

4. A method according to claim 1, wherein the placement of a mouse pointer over the activation areas changes the appearance of the selectable objects.

5. A method according to claim 1, wherein characteristics of the activation areas are defined by user input.

6. A computer program for selecting a plurality of selectable objects defined by an object area in a display with a pointing device, the computer program comprising:

a storage medium;

activation code on the storage medium for providing a plurality of activation areas for a plurality of selectable objects in the display, the selectable objects surrounded by an object area which defines the boundaries of said selectable objects which must be contacted by said pointing device for selection, the activation areas surrounding the selectable objects in the display and being greater than the object area, said activation areas expanding the boundary of said selectable objects which must be contacted by said pointing device for selection, the size of the activation areas determined by an expansion boundary having a border that outlines the size and shape of said activation areas in accordance with properties of the selectable object and of the display, and said activation areas enlarged to maximum activation areas without overlapping any one activation area with any other activation area.

7. A computer program according to claim 6, further comprising expansion code on the storage medium to maximize the size of the activation areas within the display.

8. A computer program according to claim 6, further comprising selection code on the storage medium responsive to user input and the activation code, for performing a selection operation in the activation areas to select the selectable objects.

9. A computer program according to claim 6, further comprising change code on the storage medium for changing the characteristics of the activation areas.
