than global positioning systems and, since the codes are embedded in the

9.8 Conclusion and Future Work
The work reported in this chapter could be extended with more focused
searches for associations, timestamps, and specific links to information
through semantic web operations. This will lead to an integrated information
space that brings together and seamlessly interlinks the physical world with
the information world. The active knowledge for semantic surfaces layered
on physical objects and backgrounds then become physical windows into the
semantic web and provide for instant, context-dependent access to its vast
information resources. In other words, the position-based knowledge acqui-
sition and pervasive carpet encoding will open new, promising ways for
creating and searching information resources, and for developing effective
educational materials and corresponding educational processes. They will be
a self-explanatory and self-awareness basis for a great variety of technologies
related to concepts of ubiquitous computing. To implement that, however,
some standards on code assignments and corresponding code recognition
devices would need to be introduced for codes of different scales.
