Abstract

A technique is disclosed which facilitates the selection by a user of a graphic object on a display screen. Selection is by means of a pointing cursor which is moved about the display screen by means of a pointing device having a select button. When the pointing cursor is brought within a predetermined distance of a graphic object, the point on the graphic object closest to the pointing cursor is highlighted to show the user that that graphic object would be selected if the select button were pressed. If the user presses the select button when a point on a graphic object is highlighted, the entire graphic object is highlighted to indicate that it has been selected.

Claims

1. A method of facilitating the selection of graphic data on a display screen of a computer comprising the steps of:

displaying a pointing cursor on said display screen;

pointing to a graphic object displayed on said display screen by moving said pointing cursor on said display screen proximate to said graphic object by means of a pointing device connected to said computer; and

highlighting only a portion of said graphic object when pointed to by said pointing cursor within a predetermined distance to indicate the object that would be selected by an input signal to said computer, said highlighting step being performed exclusive of the step of displaying said pointing cursor.

2. The method as recited in claim 1 wherein said pointing device has a select button and the step of highlighting is performed when said pointing cursor is moved to within said predetermined distance of the graphic object to indicate that the graphic object would be selected if said select button were pressed.

3. The method as recited in claim 2 wherein the step of highlighting is performed by highlighting the point on the graphic object closest to said pointing cursor.

4. The method as recited in claim 3 wherein highlighting the point is performed by increasing the intensity of the point.

5. The method as recited in claim 3 wherein highlighting the point is performed by changing the color of the point.

6. The method as recited in claim 3 wherein highlighting the point is performed by blinking the point on and off.

7. The method as recited in claim 3 wherein highlighting the point is performed by displaying a geometric shape at the position of the point.

8. The method as recited in claim 7 wherein the step of displaying is performed by generating a circle surrounding the point.

9. The method as recited in claim 3 further comprising the step of highlighting the entire graphic object having a point thereon highlighted when the select button is pressed.

10. The method as recited in claim 9 further wherein a selected graphic object can be deselected comprising the steps of:

moving said pointing cursor away from the selected and highlighted graphic object;

pressing the select button again; and

dehighlighting the now deselected graphic object.
