Constraints in spatial structures

People have become used to paper as an information carrier over thousands of years. Paper is usually easy to handle and has been adopted as a metaphor for information structures in computer applications. This article gives a brief overview of our analysis on real world bindings. We further compare those to some metaphor-based spatial structure applications. We conclude that the high abstract implementation level in spatial structure applications takes away additional metainformation that may be useful for the user to find information quicker.
