Method and apparatus for dynamically grouping a plurality of graphic objects
First Claim
1. A method for dynamically grouping a plurality of graphic objects displayed on a graphic input display device, comprising:
- determining at least one distance, each distance being between a pair of graphic objects and based on a plurality of different types of distance measures; and
forming a cluster tree for the graphic objects based upon each determined distance, each cluster level of the cluster tree defining one new cluster of the graphic objects.

Abstract
When dynamically grouping a plurality of graphic objects, such as displayed on a graphic input display apparatus, a cluster tree is formed for the plurality of graphic objects. The cluster tree is based on a plurality of different types of distance measures. These include a time distance and a spatial distance. These distances are combined to form a distance metric indicting a distance between a pair of the graphic objects. Each level of the cluster tree defines a new cluster of the graphic objects. At least one of the graphic objects is selected. The different cluster levels of the cluster tree containing the selected graphic object are displayable. The displayed cluster of the graphic objects can be modified to increase or decrease the cluster level of the cluster containing the selected graphic object.

15. A method for dynamically grouping a plurality of graphic objects displayed on a graphic input display device, comprising:
-
initially grouping each of the plurality of graphic objects as its own cluster; determining at least one pairwise distance, each pairwise distance being between a pair of the clusters and based on a combination of a time distance between creation of the pair of clusters and a spatial distance between the pair of clusters; and merging the pair of clusters closest to each other based on the at least one pairwise distance to form a single cluster and a cluster level. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A system for dynamically grouping a plurality of graphic objects, comprising:
-
a graphic input display device for at least displaying the plurality of graphic objects; a control system communicating with the graphic input display device, the control system forming a cluster tree of the plurality of graphic objects by combining different types of distance measures between at least one pair of graphic objects to form each level of the cluster tree; and a memory for storing the graphic objects and the cluster tree. - View Dependent Claims (36, 37, 38, 39, 40)
