    • Experimental Study of Haptic Interface Considering Myoelectrical Activity 

      Sone, Junji; Inoue, R.; Tsuyuki, S.; Ishikawa, K.; Yamada, K.; Kaneko, I.; Tokuyama, Y.; Fujita, K.; Sato, Makoto (The Eurographics Association, 2007)
      Many types of haptic interface for virtual reality have been proposed. These haptic interfaces mostly contain earth grounding linkages. In this study, we considered wearable haptic interfaces for improved flexibility. It ...
    • Evaluating the Effects of Haptics on Presence while Traveling in a Desktop Virtual Environment 

      Jorissen, Pieter; Vanacken, Lode; Lamotte, Wim; Coninx, Karin (The Eurographics Association, 2007)
      Virtual reality applications seek to fully immerse participants into their virtual world experience. The investigation of how stimuli on the different senses influence the users is therefore crucial. As navigation is one ...
    • A Quantitative Assessment of the Impact on Spatial Understanding of Exploring a Complex Immersive Virtual Environment using Augmented Real Walking versus Flying 

      Interrante, Victoria; O'Rourke, Eleanor; Gray, Leanne; Anderson, Lee; Ries, Brian (The Eurographics Association, 2007)
      When an immersive virtual environment spans an area that is larger than the available physical space for real walking, one may use an augmented walking method such as Seven League Boots to enable participants to explore ...
