Abstract
Abstract A method for accessing and using stored electronic documents. The stored documents are presented to the user in a manner which visually simulates document types that most users are familiar with, such as books. Each page of the document is divided into frames. Both the individual pages and the frames comprising them are ranked based on locational, representational and logical attributes. These rankings are called herein semantic hints. The user determines the review speed of the document, and that review speed in turn determines which frames and pages will be moved from memory into cache at any particular time, as well as determining which of the pages and frames will be either fully or partially rendered on the display.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
134 words
A method for viewing electronically stored documents at different speeds, the speed being adjustable by the user, the method comprising the steps of: storing the electronic documents in long term memory as a plurality of pages, a page being further stored as a plurality of frames, each frame comprising a data type, each data type encompassing a class of image features displayed in one or more frames; rating the stored frames, the rating depending on at least the frame's data type and/or location; and moving a select group of frames from the long term memory into a cache memory depending upon a selection criteria comprising the user selected viewing speed and the rating of the frame, said select group of frames consisting of only frames to be displayed in accord with said selection criteria.
Claim 2
Independent Claim
134 words
A method for viewing electronically stored documents at different speeds, the speed being adjustable by the user, the method comprising the steps of: storing the electronic documents in long term memory as a plurality of pages, a page being further stored as a plurality of frames, each frame comprising a data type, each data type encompassing a class of image features displayed in one or more frames; rating the stored frames, the rating depending on at least the frame's data type and/or location; and moving a select group of frames from the long term memory into a cache memory depending upon a selection criteria comprising the user selected viewing speed and the rating of the frame, said select group of frames consisting of only frames to be displayed in accord with said selection criteria.
Claim 3
Dependent Claim
29 words
A method according to claim 1 wherein at a first user selected viewing speed, all of the stored frames are moved into the cache memory regardless of their rating.
Claim 4
Dependent Claim
30 words
A method according to claim 2 wherein, at a second user selected viewing speed, only frames having a rating above a first predetermined rating are moved into the cache memory.
Claim 5
Dependent Claim
36 words
A method according to claim 3 wherein, at a third user selected viewing speed, only frames having a rating above a second predetermined rating greater than the first predetermined rating are moved into the cache memory.
Claim 6
Dependent Claim
42 words
A method according to claim 4 wherein the electronically stored document is made visually to resemble a book on display screen, and wherein selecting the first, second and third viewing speeds incrementally increases the speed at which pages of the book appear.
Claim 7
Dependent Claim
16 words
A method according to claim 1 wherein one or more of stored pages are also rated.
Claim 8
Dependent Claim
27 words
A method according to claim 6 wherein more weight is given to page ratings than frame ratings in determining which frames are moved into the cache memory.
Claim 9
Dependent Claim
27 words
A method according to claim 6 wherein the page rating determines whether a page is pre-loaded into the cache memory prior to document viewing by a user.
Claim 10
Dependent Claim
62 words
A method according to claim 1 wherein fewer frames of each successive page are moved from the long term memory to the cache memory as the user selects increasingly higher viewing speeds, with at least one frame from each successive page which indicates the position of the frame within the book being moved from the long term memory to the cache memory.
Claim 11
Dependent Claim
50 words
A method according to claim 1 , wherein for a page of which not all frames are stored in a cache memory, the additional step of displaying said page and replacing a part of the information in said page by one or more default renditions representative of a data type.
Claim 12
Dependent Claim
51 words
A method according to claim 1 wherein three attributes are recorded for a frame and influence its rating, one attribute indicating the appearance of the frame, one attribute indicating the logical function of the frame in the page and the other attribute indicating the position of the frame on the page.
Claim 13
Independent Claim
182 words
A system for permitting a user to view electronically stored documents at different speeds, the system comprising: a long term memory for storing the documents as a series of pages, each page in turn being formed from a plurality of frames, a cache memory for temporarily storing frames recalled from the long term memory; a processor coupled to the cache memory and the long term memory so that, on the processor receiving from a user both a request for a stored document and a requested viewing speed, the processor transfers selected frames from the long term memory into the cache memory, said selected frames that are transferred consisting of only frames to be displayed in accord with said request for said stored document and said requested viewing speed; a display coupled to the processor for displaying pages and frames; wherein each frame is rated relative to its viewing priority based at least on image contents of the frame and in that the rating of a frame and the requested viewing speed determine whether the processor recalls the frame to the cache memory.
Claim 14
Independent Claim
182 words
A system for permitting a user to view electronically stored documents at different speeds, the system comprising: a long term memory for storing the documents as a series of pages, each page in turn being formed from a plurality of frames, a cache memory for temporarily storing frames recalled from the long term memory; a processor coupled to the cache memory and the long term memory so that, on the processor receiving from a user both a request for a stored document and a requested viewing speed, the processor transfers selected frames from the long term memory into the cache memory, said selected frames that are transferred consisting of only frames to be displayed in accord with said request for said stored document and said requested viewing speed; a display coupled to the processor for displaying pages and frames; wherein each frame is rated relative to its viewing priority based at least on image contents of the frame and in that the rating of a frame and the requested viewing speed determine whether the processor recalls the frame to the cache memory.
Claim 15
Dependent Claim
28 words
A system according to claim 12 wherein the processor recalls increasingly fewer frames from the long term memory to the cache memory as the requested viewing speed increases.
Claim 16
Independent Claim
142 words
A method for viewing electronically stored documents at different speeds, the speed being adjustable by the user, the method comprising the steps of: storing the electronic documents in long term memory as a plurality of pages, a page being further stored as a plurality of frames, each frame comprising a data type, each data type encompassing a class of image features displayed in one or more frames; rating the stored pages and frames, the rating of a stored page or frame depending on at least one of a contextual attribute or a locational attribute of said page or frame; and moving a select group of frames from the long term memory into a cache memory depending upon a selection criteria comprising the user selected viewing speed and the rating of the frames in the group or pages containing frames in the group.
Claim 17
Independent Claim
142 words
A method for viewing electronically stored documents at different speeds, the speed being adjustable by the user, the method comprising the steps of: storing the electronic documents in long term memory as a plurality of pages, a page being further stored as a plurality of frames, each frame comprising a data type, each data type encompassing a class of image features displayed in one or more frames; rating the stored pages and frames, the rating of a stored page or frame depending on at least one of a contextual attribute or a locational attribute of said page or frame; and moving a select group of frames from the long term memory into a cache memory depending upon a selection criteria comprising the user selected viewing speed and the rating of the frames in the group or pages containing frames in the group.
