Abstract

A primary body of data is displayable on a screen and a supporting body of data is relatable to an annotation tag present in the primary body of textual data. An annotation tag having a predetermined size in the primary body of data is selected, and negotiations ensue between the primary body of data and the supporting body to determine a space into which the supporting body of data can be fitted while maintaining a substantially unobstructed view of the primary body of data. Generally, this negotiated space is sized larger than the original predetermined size of the annotation tag. An animation sequence is used to position the supporting body of data in the negotiated space.

Claims

1. A method for presenting a primary body of data displayable on a screen and a supporting body of data relatable to an annotation tag present in the primary body of data, the method comprising the steps of

selecting an annotation tag having a predetermined size in the primary body of data,

negotiating between the primary body of data and the supporting body of data to determine a space into which the supporting body of data can be fitted while minimizing obstruction of the primary body of data, with the negotiated space being sized larger than the predetermined size of the annotation tag,

positioning the supporting body of data in the negotiated space, and

generating display data that alters the display characteristics of at least a portion of the primary body of data so that the visual prominence of the at least a portion of the primary body of data in the negotiated space is reduced so that the at least a portion of the primary body of data wilt appear less salient then the supporting body of data.

2. The method of claim 1, further comprising the step of animating an expansion of the annotation tag into the negotiated space.

3. The method of claim 1, further comprising the step of animating a contraction of the supporting body of data positioned in the negotiated space back into the annotation tag.

4. The method of claim 1, wherein the supporting body of data is a user defined handwritten annotation.

5. The method of claim 1, wherein at least one of the primary body of data and the supporting body of data is substantially text.

6. The method of claim 1, wherein at least one of the primary body of data and the supporting body of data is substantially graphics.

7. The method of claim 1, wherein at least one of the primary body of data and the supporting body of data contains both text and graphics.

8. The method of claim 1, wherein the annotation tag is at least a fragment of the supporting body of data.

9. The method of claim 1, wherein the annotation tag is text of the supporting body of data, initially sized to have a smaller typesize than typesize of the primary body of data.

10. The method of claim 1, wherein the annotation tag is a hyperlink to the supporting body of data.

11. A computer controlled display system for displaying a primary body of data on a screen and a supporting body of data relatable to an annotation tag present in the primary body of data, the system comprising:

a selection device for selecting an annotation tag, said annotation tag having a predetermined size in the primary body of data,

a first processing element for negotiating between the primary body of data and the supporting body of data a space into which the supporting body of data can be fitted while minimizing obstruction of the primary body of data, with the negotiated space being sized larger than the predetermined size of the annotation tag, and

a second processing element for positioning the supporting body of data in the negotiated space for display on the screen and generating display data that alters the display characteristics of at least a portion of the primary body of data so that the visual prominence of the at least a portion of the primary body of data in the negotiated space is reduced so that it will appear less salient then the supporting body of data.
