What is the space for?: the role of space in authoring hypertext representations Yasuhiro Yamamoto, Kumiyo Nakakoji, Yoshiyuki Nishinaka, Mitsuhiro Asada, and Ryouichi Matsuda   View Paper (PDF)   Return to Transformations and adaptations Abstract This paper describes our approach of using spatial hypertext as a means separated from an end representation for hypertext authoring. By taking advantage of the power of rich interpretation and constant grounding capabilities of a spatial hypertext representation, ART001, ART006, and ART014 use spatial hypertext as a means for authoring linear, hierarchical, and network structures, respectively. The role of the space of the tools includes controlling a structure and annotating a structure. The three prototyped tools have been developed to demonstrate what visual interaction design concerns need to be taken into account to integrate a spatial hypertext as a means with another structural representation as an end. The paper concludes with a discussion of what it means to separate representations as a means from those as an end in hypertext authoring. ©2006 Association for Computing Machinery
