Abstract
Abstract The invention is a method to mark hypertext links in an image map that have been traversed. The invention actually modifies the image map of the links by inserting a marker or changing the color associated with the coordinates of a particular image link on the image map. The history files of links that have been traversed are first checked to determine if the image has changed or is otherwise out of date. The image map or a copy of the image map is then modified and displayed.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
107 words
A method to mark traversed hypertext clickable image links on an image map, comprising the steps of: (a) retrieving a history of the coordinates of at least one hypertext clickable image link on a hypertext image map having a plurality of the hypertext clickable image links, of which at least one of said image links has been traversed; (b) determining if the image map has been modified since last viewed; (c) if not, modifying the image map at or substantially near the coordinates of the at least one traversed image link with at least one marker; (d) displaying the image map with the at least one marker.
Claim 2
Independent Claim
107 words
A method to mark traversed hypertext clickable image links on an image map, comprising the steps of: (a) retrieving a history of the coordinates of at least one hypertext clickable image link on a hypertext image map having a plurality of the hypertext clickable image links, of which at least one of said image links has been traversed; (b) determining if the image map has been modified since last viewed; (c) if not, modifying the image map at or substantially near the coordinates of the at least one traversed image link with at least one marker; (d) displaying the image map with the at least one marker.
Claim 3
Dependent Claim
36 words
The method of claim 1, further comprising the step of: (b-1) determining if the last time the image map was viewed precedes a preset user timestamp, and if not, then continuing with steps (c) and (d).
Claim 4
Dependent Claim
37 words
The method of claim 1, further comprising the step of: (c-1) modifying the pixels at or substantially near the coordinates of the at least one traversed image link to create a bit map image of the marker.
Claim 5
Dependent Claim
15 words
The method of claim 1, wherein said image map is written in HyperText Markup Language.
Claim 6
Dependent Claim
17 words
The method of claim 4, wherein at least one of said image links has an ISMAP attribute.
Claim 7
Dependent Claim
12 words
The method of claim 3, wherein the marker is an alphanumeric character.
Claim 8
Dependent Claim
24 words
The method of claim 3, wherein the marker is a change in the shading or hue of the at least one traversed image link.
Claim 9
Independent Claim
133 words
A method to mark traversed hypertext clickable image links on an image map, comprising the steps of: (a) retrieving a history of the coordinates on an image map indicating the position of at least one of said hypertext clickable image links that has been traversed, said image map having more than one hypertext clickable image links; (b) determining if the image map has been modified since last viewed; (c) determining if the last time the image map was viewed precedes a preset user timestamp; (d) if neither (b) nor (c), then modifying the image map with a marker by modifying the pixels at or substantially near the coordinates of the at least one traversed image link to create a bit map image of the marker; (e) displaying the image map with the marker.
Claim 10
Independent Claim
133 words
A method to mark traversed hypertext clickable image links on an image map, comprising the steps of: (a) retrieving a history of the coordinates on an image map indicating the position of at least one of said hypertext clickable image links that has been traversed, said image map having more than one hypertext clickable image links; (b) determining if the image map has been modified since last viewed; (c) determining if the last time the image map was viewed precedes a preset user timestamp; (d) if neither (b) nor (c), then modifying the image map with a marker by modifying the pixels at or substantially near the coordinates of the at least one traversed image link to create a bit map image of the marker; (e) displaying the image map with the marker.
Claim 11
Independent Claim
96 words
A method of marking traversed image links identified by coordinates on an image map, comprising: (a) retrieving a history of the coordinates identifying at least one image link that has been traversed on an image map having a plurality of said image links; (b) determining if the image map has been modified since last viewed; (c) if not, copying the image map; (d) modifying the copied image map at or substantially near the coordinates of the at least one traversed image link with a marker; (e) overlaying the modified image map onto the original image map.
Claim 12
Independent Claim
96 words
A method of marking traversed image links identified by coordinates on an image map, comprising: (a) retrieving a history of the coordinates identifying at least one image link that has been traversed on an image map having a plurality of said image links; (b) determining if the image map has been modified since last viewed; (c) if not, copying the image map; (d) modifying the copied image map at or substantially near the coordinates of the at least one traversed image link with a marker; (e) overlaying the modified image map onto the original image map.
Claim 13
Dependent Claim
34 words
The method of claim 9, wherein the step of modifying further comprises: (d-1) adding the marker by changing the pixels at or substantially near the coordinates of the at least one traversed image link.
Claim 14
Dependent Claim
37 words
The method of claim 9, further comprising the step of: (b-1) determining if the last time the image map was viewed precedes a preset user timestamp, and if not, then continuing with steps (c), (d), and (e).
Claim 15
Dependent Claim

The method of claim 10, wherein said image map is written in HyperText Markup Language.
Claim 16
Dependent Claim

Claim 19
Independent Claim
