An enhanced information collage that combines a computational system with a
physical information collage to preserve the advantages of conventional
information collages while alleviating many problems associated with such
collages. A physical information collage (e.g. a pin board with spatially
differentiated pin mounted task cards, each card having a detectable
identity tag) can be made part of a computational system by sensing the
identity, position, and contents of the collage component artifacts. In
effect, each collage component has its content and position stored in a
database, with movement of a particular component resulting in update of
the database to record the new position of that component. Further
provided are Operator Icon components which may be used to provide digital
services, such as combining, erasing, saving, or transferring, to other
collage components.
