document: A dual-mode user interface for accessing 3D content on the world wide web The Web evolved from a text-based system to the current rich and interactive medium that supports images , 2D graphics , audio and video . The major media type that is still missing is 3D graphics . Although various approaches have been proposed ( most notably VRML\/X3D ) , they have not been widely adopted . One reason for the limited acceptance is the lack of 3D interaction techniques that are optimal for the hypertext-based Web interface . We present a novel strategy for accessing integrated information spaces , where hypertext and 3D graphics data are simultaneously available and linked . We introduce a user interface that has two modes between which a user can switch anytime : the driven by simple hypertext-based interactions `` do n't - make-me-think '' mode , where a 3D scene is embedded in hypertext and the more immersive 3D `` take-me-to-the-Wonderland '' mode , which immerses the hypertextual annotations into the 3D scene . A user study is presented , which characterizes the user interface in terms of its efficiency and usability .
