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.

During viewing of most objects in one's everyday environment, the binocular and monocular relative depth cues interact in a harmonious, concordant and reinforcing manner to provide perceptual stability. However, when one views pictorial art, these binocular and monocular cues are discordant, and thus a perceptual “cue conflict” arises. This acts to reduce the relative apparent perceived distance of objects in a painting, thus producing overall perceptual depth “flattening.” The theory and physiology underlying this phenomenon are discussed.

Interactive Internet artworks invite viewers to become involved as user-participants as the creative process unfolds. Through analysis of selected Internet projects, the authors discuss the potential for facilitating an interactive, creative experience for participants in the process of making dance. This study was carried out in 1998 and 1999, but the findings remain relevant, as there have been few subsequent develop-ments in the field.

The current abundance of scholarship concerning the technological development of photography has coexisted with a proportionate absence of recent critical analysis of photographic images. Given photography's long-standing embrace of technological advances, even predating the portable camera or roll film, this article revisits some early uses of scientific photography in order to clarify the impact of digital technology on contempo-rary photographic practice.

The author describes her public-art projects and installa-tions, in which she has em-ployed various combinations of video, photography, audio, sculpture and performance, often in collaboration with artist Molly Cleator. The pieces spectacularize unresolved conflicts between the artists regarding what is personally truthful as compared to what society dictates, especially concerning the “three deviants”: women, art and nature. The artists question who defines these related realities and how. The author has also offered hundreds of artists a forum called L.A.
