Abstract
ABSTRACT OF THE DISCLOSURE
A display system and method is disclosed for use in conjunction with the cursor control device, which permits a user to select command options simply by movement of the displayed cursor over a "pull-down" menu bar,
A display system and method is disclosed for use in conjunction with the cursor control device, which permits a user to select command options simply by movement of the displayed cursor over a "pull-down" menu bar,
Claims (9)
1. A computer controlled display system having a display wherein a plurality of command options are displayed along a menu bar and sub-command items corresponding to each option are displayed once said option has been selected, and including a cursor control means for selectively positioning a cursor on said display, comprising:
first display means coupled to said computer for generating and displaying said menu bar comprising said plurality of command options;
signal generation means coupled to said cursor control means for signalling said computer of an option choice once said cursor is positioned over a first predetermined area on said display corresponding to an option to be selected;
second display means coupled to said computer for generating and displaying said sub-command items corresponding to said selected option;
signal modification means coupled to said signal generation means for altering said signal to said computer once said cursor is positioned over a second predetermined area corresponding to a sub-command item to be selected;
whereby an option and a sub-command item is selected and executed by said computer.
first display means coupled to said computer for generating and displaying said menu bar comprising said plurality of command options;
signal generation means coupled to said cursor control means for signalling said computer of an option choice once said cursor is positioned over a first predetermined area on said display corresponding to an option to be selected;
second display means coupled to said computer for generating and displaying said sub-command items corresponding to said selected option;
signal modification means coupled to said signal generation means for altering said signal to said computer once said cursor is positioned over a second predetermined area corresponding to a sub-command item to be selected;
whereby an option and a sub-command item is selected and executed by said computer.
2. The display system of claim 1 wherein said signal generation means comprises selecting a first position on a two position switch located on said cursor control means.
3 The display system of claim 2 wherein said signal modification means comprises selecting a second position on said two position switch.
4. The display system of claim 3 wherein said cursor control means includes:
a housing including a base having an opening for the passage of a rotatable ball;
a unitary frame disposed on said base including:
a domed portion integrally formed with said frame substantially surrounding and retaining said rotatable ball;
said domed portion having first and second cut-outs through said dome disposed substantially at 90 degrees with respect to one another, and a third cut-out disposed at an angle with respect to said first and second cut-outs;
X-Y position indicating means passing through said first and second cut-outs, for converting the rotation of said ball into signals indicative of X-Y positions on said display system;
biasing means passing through said third cut-out, for biasing said ball against said X-Y position indicating means;
means for removing said ball from said domed portion through said opening in said base, such that said ball and the interior of said dome may be serviced;
whereby said option and sub-command item may be selected by movement of said cursor control means over a surface such that a portion of said ball is in contact with said surface.
a housing including a base having an opening for the passage of a rotatable ball;
a unitary frame disposed on said base including:
a domed portion integrally formed with said frame substantially surrounding and retaining said rotatable ball;
said domed portion having first and second cut-outs through said dome disposed substantially at 90 degrees with respect to one another, and a third cut-out disposed at an angle with respect to said first and second cut-outs;
X-Y position indicating means passing through said first and second cut-outs, for converting the rotation of said ball into signals indicative of X-Y positions on said display system;
biasing means passing through said third cut-out, for biasing said ball against said X-Y position indicating means;
means for removing said ball from said domed portion through said opening in said base, such that said ball and the interior of said dome may be serviced;
whereby said option and sub-command item may be selected by movement of said cursor control means over a surface such that a portion of said ball is in contact with said surface.
5. In a display system controlled by a computer wherein command options are displayed along a menu bar and sub-command items corresponding to each option are displayed once said option has been selected, including a cursor control device for positioning a cursor on said display system, a method for selecting an option and an item, comprising the steps of:
(a) positioning a cursor on said display using said cursor control device such that said cursor lies over a first predetermined area on said display corresponding to the option to be selected;
(b) providing a signal to said computer indicating that the option associated with said cursor position has been selected;
(c) positioning said cursor using said cursor con-trol device over a second predetermined area on said display corresponding to the sub-command item to be selected;
(d) altering said signal to said computer indicating that the item associated with said cursor position has been selected;
whereby an option displayed on said menu bar and an item associated with said option is selected.
(a) positioning a cursor on said display using said cursor control device such that said cursor lies over a first predetermined area on said display corresponding to the option to be selected;
(b) providing a signal to said computer indicating that the option associated with said cursor position has been selected;
(c) positioning said cursor using said cursor con-trol device over a second predetermined area on said display corresponding to the sub-command item to be selected;
(d) altering said signal to said computer indicating that the item associated with said cursor position has been selected;
whereby an option displayed on said menu bar and an item associated with said option is selected.
6. The method as defined by claim 5 wherein step (b) comprises the step of activating switching means disposed on said cursor control device.
7. The method as defined by claim 6 wherein step (d) comprises the step of deactivating said switching means.
8. The method as defined by claim 7 wherein step (c) comprises the step of moving said cursor control device over a surface, such that signals indicative of locations on said display are provided to said computer.
9. The method as defined by claim 8 where said computer displays said sub-command items generally below said option on said menu bar.
