Spatial Hypertext for linear-information authoring: Interaction design and system development based on the ART Design principle Yasuhiro Yamamoto, Kumiyo Nakakoji, and Atsushi Aoki   View Paper (PDF)   Return to Spatial Hypertext Abstract We have developed a series of spatial hypertext systems that support early stages of linear-information authoring, such as paper writing and movie editing. They are designed based on the ART (Amplifying Representational Talkback) principle, which emphasizes the importance of visual interaction and the power of external representations. The systems use spatial hypertext not as a medium for representing final artifacts but as a means of interacting with linear information during an authoring process. This paper first describes the role and the effect of the spatial hypertext representation plays in support of early stages of authoring linear information, and explains the ART interaction model for the approach. The ART#001 system, which supports early stages of writing, is described in detail and the other three ART systems are used to illustrate the essential aspects of our approach. The paper concludes with a discussion on the semiotic interpretation of spatial hypertext as a representation, and on the innovative use of spatial hypertext as an instrument to compose information, rather than as an information medium.
