1 Vol. 47 No.4 情報処理学会論文誌 Apr Vol. 47 No. 4 Apr MR Design and Implementation of Minority-Report-Style Gesture Interaction with Wide-view Electronic Working Space Asako Kimura, Fumihisa Shibata, Takeshi Tsuruta, Toshio Sakai, Makiko Oniyanagi and Hideyuki Tamura Combination of a wide-view display and hand gesture operations that is presented in the feature film Minority Report is to be considered as what the computer-human in-teraction should be. Assumption and categorization of works suitable to Wide-view Electronic Working Space were the starting point of our study and we established a backbone system and a detection method for gesture commands. Now we propose MR-Cube system which will bloom to be a mixed reality system having included 3D image display and introduction of real objects based on the backbone system. We have developed a video playing and editing system and a system to browse, edit and manage medical images as prototypes in order to verify their operation and usability WIMP (HI) 1) 2)3) 4)5) PC Graduate School of Science and Engineering, Ritsumeikan University HI 1 (2002) SF 2001 (1968) (2004) 60 SF 6) post-wimp HI HI MIT Media Lab.
