Use of image space not as a metaphor but as a genuine information carrier that is reactive to visual querries by users

- focus and context

- omnipresence of all information in the frame of perception

- visual memory of the interaction Topology
The grid tracks the point of attention and each cell contains an attention counter that is constantly updated.The scaling is row and column based to keep orthogonality.I later found similar work by Y.K.Leung from Swin- burne University of Technology in his paper “A review and Taxonomy of Distortion-Oriented Presentation Techniques ”featured in the col- lection Information visualization -using vision to think and by Ramana Rao and Stuart K. Card “The table lens...”from Xerox Palo Alto Research Center..My implementation of the distortion grid differs from previous implementations in that it uses a simple accumulative attention tracking system where each cell has a counter which is used in determining the final proportion as opposed to the formula based approach of the earlier work.The difference is mainly that the cells have a sense of history since their expansion takes some time to restore itself and therefore the users movement pattern is visible over time.In addition I explored the notion of his- tory in the navigation of the grid.The interesting effect is that if the navigation history is drawn as geometrically based on the center of the cells vis- ited in time,the geometry changes constantly while the topology remains the same.
