Immersive Virtual Reality (IVR) environments would seem naturally to lend themselves to hands-on approaches to learning, but the success of such virtual “direct experience” depends heavily on the design of interface and interaction techniques. IVR presents surprisingly difficult interface challenges, and the study of interface and interaction design for educational IVR use is just beginning.

In the process of creativity, digital technology offers new ways to translate and transform. The author presents his approach to drawing as a gateway to exploring these possibilities. His particular concern is with the notion of computer-human integration. He suggests that possibilities offered by such integration will enable forms of expression unique to this process to emerge. Two systems that the author has used to further his search are described. His reflections on how a particular system of computer-human integration might develop in the future are noted.

The exhibition Constructs and Re-Constructions provided a survey of the author's artwork and formed the basis for this paper. It included four prints, consisting of notes based on early documentation, representing four different conceptual stages in using computer technology. As each is discussed in turn, it is shown that the computer provides a significant enhancement to our ability to handle and consider the underlying structures of artworks and art systems in the many forms that they may take.

The article develops an analysis of visual knowledge and the use of pictures in electronic communication. The author focuses in particular on indexical images, which we use in navigat-ing multimedia documents and the Web. For this purpose, the author bases his study on the one hand on semiotics, the core concepts of which were intro-duced by C.S. Peirce at the beginning of the last century; and on the other hand on a more classical historical analy-sis, in order to point out the deep roots of the concepts used in contemporary computer-based communication.
