Conclusions

The main difficulties when implementing the visual book viewer have been practical ones, which were related to the lack of technology which was able to provide tools for displaying on screen pages with resolution the same as or comparable with the paper ones. This limitation has restricted the possibility of testing on a large scale the prototype of the visual book, but at the same time has focused this research on a wider field such as the definition of guidelines for the production of “good” electronic books, thus avoiding the risk of ending up with just another interesting prototype which makes no impact on the market or on similar research projects. The study involved in the production of the visual book system has been instead used as a basis for elaborating and defining a set of heuristic rules that can be used as a basis for the definition and design of electronic publications in general.

There is of course a wide margin left for improvement and further experimentations. In particular implementation issues such as the use of suitable screens for displaying electronic information is still open to a possible technology related solution, as well as the use of different platforms and standard formats for input data.
