Abstract
The paper describes how high-level knowledge about visual images could
be represented and further interpreted through system-active and systempassive
tutorial interactions. The ideas lend themselves to the design and
implementation of a category of Intelligent Tutoring Systems aimed at the
teaching of abnormalities in highly visual domains, like medical diagnostic
imaging. The involved problems are treated through (1) a domainindependent,
object-oriented method for managing the complexity of
design representations and (2) a model of dialogue interpretation for
implementing tutorial interactions. The method and the model are both
supported here by implemented, computer-based tools that integrate the
multi-layer environment RUI. To evaluate the power of RUI, empirical
observations have been carried out, focussing on the generality of the
design methodology as well as on the usability of the interface. We draw
conclusions about the suitability of object-oriented principles in the
context of ITSs evolution.
