Abstract
Abstract A method and system for generating an interactive, multi-resolution presentation space of information structures within a computer enabling a user to navigate and interact with the information. The presentation space is hierarchically structured into a tree of nested visualization elements. A visual display is generated for the user which has a plurality of iconic representations and visual features corresponding to the visualization elements and the parameters defined for each visualization element. The user is allowed to interact in the presentation space through a point of view or avatar. The viewing resolution of the avatar is varied depending on the position of the avatar relative to a visualization element. Culling and pruning of the presentation space is performed depending on the size of a visualization element and its distance from the avatar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A method for enabling a user to navigate
and access information objects within a structured
presentation space, the information objects being stored
in a hierarchical structured format whereby a base
information object may have a parent information object
and at least one child information object; characterized
by (i) modeling the information objects to be
within the structured presentation space, whereby
the base information object is located within the
parent information object, and the child information
object is located within the base information
object; (ii) assigning a view point within the
presentation space; (iii) in response to input by the user, moving
the view point within the structured presentation
space, wherein the view point may be moved between
the information object, the parent information
object, and the child information object, and
wherein the scale of movement of the view point is
based relative to the scale of the information
object containing the view point; and (iv) displaying the information objects with a
multi-dimensional perspective view corresponding to
the view point, wherein each child information
object is displayed as being within the information
object, and the information object is displayed as
being within the parent information object.
Claim 2
Dependent Claim
15 words
A method according to Claim 1, wherein
each information object comprises a static information
object.
Claim 3
Dependent Claim
19 words
A method according to Claim 1, wherein
each information object comprises an information object
that is updated in real-time.
Claim 4
Independent Claim
72 words
A method according to any preceding claim
in which the information objects are displayed by the
steps of:- (a) generating a view volume within the
structured presentation space; (b) scaling the view volume in response to the
location of the view point; (c) culling information objects within the
view volume; (d) pruning information objects within the
view volume; and (e) rendering the information objects within
the view volume on the video display.
Claim 5
Independent Claim
61 words
A method according to any preceding claim
comprising the steps of: (a) generating a hierarchial presentation
space from groups of information objects; (b) generating a view port for navigating in
the presentation space; (c) responsive to the input means moving the
view port in the presentation space; and (d) updating the presentation space responsive
to the movement of the view point.
Claim 6
Independent Claim
76 words
A method according to any preceding claim
in which the information objects are modelled by the
steps of: (a) generating a presentation scene-root; (b) generating a list of information objects; (c) generating a visualization element for
each information object; (d) appending each visualization element to
the presentation scene-root; (e) generating the children of each
visualization element; (f) generating a visualization element for
each child; and (g) setting the child visualization element
coordinates relative to the parent.
Claim 7
Independent Claim
228 words
A system for enabling a user to navigate
and access information objects within a structured
presentation space, (a) a storage means (1850) for storing
information, wherein the information objects are stored
in a hierarchical structured format whereby a base
information object may have a parent information object
and at least one child information object; (b) a display (1820) for displaying visual
information to the user; (c) an input means (1830 or 1840 or 1841) for
receiving input from the user; and (d) a processing means (1810), characterized
in that the processing means is arranged to:- (i) model the information objects to be
within the structured presentation space, whereby
the base information object is located within the
parent information object, and the child information
object is located within the base information
object; (ii) assign a view point within the
presentation space; (iii) respond to the input means, moving
the view point within the structured presentation
space, wherein the view point may be moved between
the information object, the parent information
object, and the child information object, and
wherein the scale of movement of the view point is
based relative to the scale of the information
object containing the view point; and (iv) display the information objects on
said display with a multi-dimensional perspective
view corresponding to the view point, wherein each
child information object, and the information object
is
Claim 8
Dependent Claim
26 words
The system of Claim 7, wherein the storage
means (1850) further comprises a database server
processing means (1860) arranged to access at least one
information object.
Claim 9
Dependent Claim
29 words
The system of Claim 8, wherein the
database server processing means (1860) is arranged to
generate a list of parent information objects, and a list
of children information objects.
