    Command and Control Cube : a Shortcut Paradigm for Virtual Environments
    (The Eurographics Association, 2001) Grosjean, Jérôme; Coquillart, Sabine; B. Froehlich and J. Deisinger and H.-J. Bullinger
    New immersive virtual environments (VE) such as the Responsive WorkbenchTM provide users with a very attractive way of interacting with 3D computer-generated worlds. The feeling of immersion is one of the many advantages of such configurations. Being able to interact naturally with the virtual world is a very important part of this feeling. Programs developed for the virtual environments need powerful, intuitive and rapid application control interfaces. Previous work on this topic have focused on the development ofmenu systems for the VEs: converted 2D menus, hand-oriented menus and 3D widgets. To our knowledge, no 3D equivalent of the quick keyboard hotkey mechanism has ever been proposed for VEs. In this paper, we propose a 3D paradigm: the Command and Control Cube (CCC or C3), inspired by marking menus. The C3 aims to be a rapid and intuitive mechanism for issuing a set of commands to an application.

    Role of Force-cues in Path Following of 3D Trajectories in Virtual Reality
    (The Eurographics Association, 2009) Bluteau, Jeremy; Gentaz, Edouard; Payan, Yohan; Coquillart, Sabine; Michitaka Hirose and Dieter Schmalstieg and Chadwick A. Wingrave and Kunihiro Nishimura
    This paper examines the effect of adding haptic force cues (simulated inertia, compensation of gravity) during 3D-path following in large immersive virtual reality environments. Thirty-four participants were asked to follow a 3D ring-on-wire trajectory. The experiment consisted of one pre-test/control bloc of twelve trials with no haptic feedback; followed by three randomized blocs of twelve trials, where force feedbacks differed. Two levels of inertia were proposed and one level compensating the effect of gravity (No-gravity). In all blocks, participants received a real time visual warning feedback (color change), related to their spatial performance. Contrariwise to several psychophysics studies, haptic force cues did not significantly change the task performance in terms of time completion or spatial distance error. The participants however significantly reduced the time passed in the visual warning zone in the presence of haptic cues. Taken together, these results are discussed from a psychophysics and multi-sensory integration point of view.
