The current GUI is like a flight simulator whose camera points fixedly at right angle to the document, thus preventing users from looking ahead while navigating. We argue that perspective viewing of usual planar documents can help navigation. We analyze the scale implosion problem that arises with tilted cameras and we report the data of a formal experiment on document navigation with perspective views.
