摘要: Several recent research systems have provided interactive three-dimensional (3D) visualisations for supporting everyday work such as file and document management. But what improvements do these 3D interfaces offer over their traditional 2D counterparts? This paper describes the comparative evaluation of two management that differ only in number dimensions used displaying interacting with data. The system is heavily based on Robertson et al.'s Data Mountain, which supports users storing, organising retrieving “thumbnail” representations documents bookmarked Web-pages. Results show our subjects were faster at storing pages display when using interface, but not significantly so. As expected, retrieval times increased thumbnails increased. Despite lack significant differences between interfaces, subjective assessments showed a preference interface.
