A combination of the distortion viewing principle with the space memory principle.The space reacts immediately to the shift of attention but also has long-term memory of the accumulated actions.Through this layering of properties the directness of access to all parts of the space is obtained as well as the shaping of the space through the actions of all users interacting with it. The purpose of this is to be able to scale up the number of elements and users without reducing the visual clarity of the display since the other user are experienced as mediating the changes in the space.The changes in the space cause a cluster- ing or dispersion of the elements in certain areas creating various foci of attention.These clusters can be viewed as areas of higher activity where more information flows in order to get exposure to attention.
