Abstract
Abstract A system for displaying documents on a computer controlled display device is disclosed. The system displays documents either in a completely free-form, user controlled configuration or as strands, such that documents in a strand follow a strand path. The strand path is a two dimensional line through a three dimensional display space. The documents displayed on the strand are known as child documents, and each strand also has a parent document. Various constraints defining the strand are associated with the parent document, including a strand function defining the strand path, minimum and maximum separation constraints defining the distance between the child documents on the strand, and an origin constraint defining the positional relationship of the strand path to the screen object of the parent document.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
An apparatus for displaying documents, comprising: a computer controlled display device; means for displaying a strand of documents on said display device, said strand having a parent document and one or more child documents, said parent document represented on said display device by a screen object, each one of said child documents represented on said display device by a screen object displayed on a strand path, said strand path consisting of a two dimensional line through a three dimensional virtual display space in which said parent document and said child documents are arranged; and a set of one or more constraints associated with said parent document, said set of constraints including a strand function, said strand function defining said strand path when said strand function is evaluated.
Claim 2
Independent Claim
127 words
An apparatus for displaying documents, comprising: a computer controlled display device; means for displaying a strand of documents on said display device, said strand having a parent document and one or more child documents, said parent document represented on said display device by a screen object, each one of said child documents represented on said display device by a screen object displayed on a strand path, said strand path consisting of a two dimensional line through a three dimensional virtual display space in which said parent document and said child documents are arranged; and a set of one or more constraints associated with said parent document, said set of constraints including a strand function, said strand function defining said strand path when said strand function is evaluated.
Claim 3
Dependent Claim
30 words
The apparatus as in claim 1, wherein said strand function is a code representation of a mathematical equation which when interpreted and executed outputs the coordinates of said strand path.
Claim 4
Dependent Claim
39 words
The apparatus as in claim 1 wherein said set of one or more constraints associated with said parent document includes a minimum spacing constraint defining a minimum distance along said strand path between each screen object on said strand.
Claim 5
Dependent Claim
39 words
The apparatus as in claim 1 wherein said set of one or more constraints associated with said parent document includes a maximum spacing constraint defining a maximum distance along said strand path between each screen object on said strand.
Claim 6
Dependent Claim
66 words
The apparatus as in claim 1 wherein said set of one or more constraints associated with said parent document includes a knot constraint, said knot constraint defining a point on said strand path, such that any of said child documents displayed between said parent document and said knot constraint belong to a first sub-strand, and all other of said child documents belong to a second sub-strand.
Claim 7
Dependent Claim
40 words
The apparatus as in claim 1, wherein said set of one or more constraints includes an origin constraint, said origin constraint defining the position of said strand on said display device relative to the screen object of said parent document.
Claim 8
Dependent Claim
22 words
The apparatus as in claim 1, wherein said strand function is one of a set of one or more precalculated strand functions.
Claim 9
Dependent Claim
13 words
The apparatus as in claim 1, where said strand function is user defined.
