PARC showed erasable paper and other technologies that adds intelligence to documents with raw text...Scientists demonstrated paper that can be reused after printed text automatically deletes itself from the paper's surface within 24 hours. Instead of trashing or recycling after one use, a single piece of paper can be used a second time, and reused up to 100 times, said Eric Shrader, area manager at PARC.
Predictions that paper would disappear in the 1970s in favor of electronic documents were wrong, Shrader said. As the number of electronic documents produced increases, about two to five pages are printed in the office for daily use, like e-mail messages and Web pages, which are discarded or recycled after being read. Reusable paper reduces waste, is environmentally safe, and helps reduce overall printing and paper costs, Shrader said...
Scientists also demonstrated technologies to make documents more intelligent by providing a deeper meaning to text and images. This is done by cross-referencing similar data and images mined off the Internet and incorporating other sources like e-mail messages and corporate networks.
