Abstract
Abstract An apparatus is described which includes memory areas for storing an image and trigger fields for the image, and a display which indicates a cursor in one of two configurations. Circuitry is provided for moving the cursor and enabling it to implement a select operation for a particular subroutine. The apparatus employs a method which enables the trigger fields to be invisible, which method comprises: displaying the image without trigger fields; and altering the cursor on the display from one configuration to another upon the cursor being moved into an invisible trigger field to thereby indicate to the user the presence of the trigger field.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
235 words
In an apparatus including storage means for storing an image and a trigger field, a display screen means for indicating a cursor, said trigger field comprising data defining a geometric pattern that is user-positionable to define an area on said display screen means, said geometric pattern placeable at any arbitrary location on said display screen means independent of image placement, means to alter said cursor between at least two configurations, and means for moving said cursor, a method for enabling a user to identify an invisible trigger field, comprising the steps of: (a) positioning plural trigger fields at locations on said display screen, said locations user-choosable independent of whether or not said image or a portion of said image is present at said locations; (b) inhibiting display of said plural trigger fields; (c) displaying said image; (d) moving said cursor about said display screen means to bring said cursor into first locations of said display screen means where said image is displayed and into second locations of said display screen means substantially removed from where said image is displayed; and (e) altering said cursor on said display means from one said configuration to another said configuration upon said cursor being moved into a said non-displayed trigger field, to thereby indicate to the user the presence of the trigger field in either a said first location or a second second location of said display screen means.
Claim 2
Dependent Claim
235 words
In an apparatus including storage means for storing an image and a trigger field, a display screen means for indicating a cursor, said trigger field comprising data defining a geometric pattern that is user-positionable to define an area on said display screen means, said geometric pattern placeable at any arbitrary location on said display screen means independent of image placement, means to alter said cursor between at least two configurations, and means for moving said cursor, a method for enabling a user to identify an invisible trigger field, comprising the steps of: (a) positioning plural trigger fields at locations on said display screen, said locations user-choosable independent of whether or not said image or a portion of said image is present at said locations; (b) inhibiting display of said plural trigger fields; (c) displaying said image; (d) moving said cursor about said display screen means to bring said cursor into first locations of said display screen means where said image is displayed and into second locations of said display screen means substantially removed from where said image is displayed; and (e) altering said cursor on said display means from one said configuration to another said configuration upon said cursor being moved into a said non-displayed trigger field, to thereby indicate to the user the presence of the trigger field in either a said first location or a second second location of said display screen means.
Claim 3
Dependent Claim
29 words
The method of claim 1 further including the step of: (d) enabling a select operation upon the occurrence of a change of cursor configuration as recited in step (c).
Claim 4
Dependent Claim
27 words
The method of claim 2 further including the step of: (e) altering a software path upon a user's actuation of the select operation recited in step (d).
Claim 5
Dependent Claim
157 words
In a display apparatus including a cursor, the method comprising: (a) creating a world plane that contains an image; (b) positioning trigger fields at any arbitrary position in said world plane independent of image placement, said position user-choosable independently of whether or not said contained image or any portion thereof is present at a said position; (c) storing said world plane, contained image and trigger fields positioned in said world plane; (d) displaying said contained image but not said trigger fields; and (e) moving said cursor about said display apparatus to bring said cursor into first areas of said display apparatus where said image is displayed and into second areas of said display apparatus removed from where said image is displayed; and (f) visually indicting when said cursor is moved into a trigger field by a change in configuration of said cursor on said display apparatus, said change in configuration indicating a presence of said trigger field.
Claim 6
Dependent Claim
157 words
In a display apparatus including a cursor, the method comprising: (a) creating a world plane that contains an image; (b) positioning trigger fields at any arbitrary position in said world plane independent of image placement, said position user-choosable independently of whether or not said contained image or any portion thereof is present at a said position; (c) storing said world plane, contained image and trigger fields positioned in said world plane; (d) displaying said contained image but not said trigger fields; and (e) moving said cursor about said display apparatus to bring said cursor into first areas of said display apparatus where said image is displayed and into second areas of said display apparatus removed from where said image is displayed; and (f) visually indicting when said cursor is moved into a trigger field by a change in configuration of said cursor on said display apparatus, said change in configuration indicating a presence of said trigger field.
Claim 7
Dependent Claim
38 words
The method of claim 4 wherein said method comprises the added step of: (g) enabling a subroutine associated with said trigger field, only when said cursor has changed into a configuration indicating its presence in a trigger field.
Claim 8
Dependent Claim
140 words
A display apparatus comprising: memory for storing an image and at least a trigger field, said trigger field comprising data defining a geometric pattern that is user-positionable at any arbitrary location on said display screen means whether or not said image is present at said location; a display for displaying a cursor and said image; cursor placement means for enabling movement of said cursor on said display both at locations displaying said image and at locations distant from said displayed image; and arithmetic logic means for inhibiting display of said associated trigger field on said display and solely responsive to cursor placement means positioning of said cursor in a said non-displayed trigger field positioned at any said arbitrary location on said display, to indicate the presence of said non-displayed trigger field to a user by a change in cursor manifestation.
Claim 9
Dependent Claim
140 words
A display apparatus comprising: memory for storing an image and at least a trigger field, said trigger field comprising data defining a geometric pattern that is user-positionable at any arbitrary location on said display screen means whether or not said image is present at said location; a display for displaying a cursor and said image; cursor placement means for enabling movement of said cursor on said display both at locations displaying said image and at locations distant from said displayed image; and arithmetic logic means for inhibiting display of said associated trigger field on said display and solely responsive to cursor placement means positioning of said cursor in a said non-displayed trigger field positioned at any said arbitrary location on said display, to indicate the presence of said non-displayed trigger field to a user by a change in cursor manifestation.
Claim 10
Dependent Claim
42 words
The apparatus as recited in claim 6, wherein said arithmetic logic unit causes said cursor to manifest a first display configuration that is altered to a second display configuration when said cursor placement means positions said cursor in a non-displayed trigger field.
Claim 11
Dependent Claim
24 words
The apparatus of claim 6 wherein said arithmetic logic means enables a select operation upon the occurrence of a change of said cursor configuration.
Claim 12
Dependent Claim
