METHOD FOR PARTITIONING, MANAGING AND DISPLAYING A COLLABORATION SPACE AND INTERACTIVE INPUT SYSTEM EMPLOYING SAME

摘要

A computerized method of managing a collaboration space comprises partitioning the collaboration space into a plurality of tiles in a tree structure; and associating each graphic object with a tile in said tree structure; said tile being the smallest tile in the tree structure that substantially accommodate said graphic object.

1. A method of controlling one or more memory devices for storing a collaboration space, said collaboration space having one or more graphic objects therein, the method comprising:
partitioning the collaboration space into a plurality of tiles distributed at a plurality of levels in a tree structure representing a recursive subdivision of the collaboration space, the union of tiles at each level spanning the collaboration space, each tile at a level either being a leaf node or being subdivided into a plurality of smaller tiles at the next level; and associating each graphic object with an object tile in said tree structure, said object tile being the smallest tile in the tree structure that substantially accommodates said graphic object; and storing at least the object tiles in a first memory device of said one or more memory devices, wherein each object tile is stored in said first memory device as a separate record that may be independently accessed.
