===== description =====

Encoding of absolute position in a printed surface, and real-time detection using computer vision techniques.

This enables to create a movable display where litterally _moving the display, your window on the data-world_ replaces scrolling. Perfect for browsing multi-gigapixel-bitmaps, and public installations -- moving the display to navigate through an information space that is essentially larger than the display device supports a visual perception phenomenon that is known as Parks effect [ T.E Parks, 'Post Retinal Visual Storage' / American Journal of Psychology 78 (1965), p145-147  ]


A first use of this technology during the Coastomize demo August 20th 2007 ([[http://www.flcextended.be/wp/|FLC-extended]] and W&K Sint-Lucas Architectuur).  -- this proof of concept demo did wonderfull (video material should be coming online .soon soon soon)
