• Higher Levels of Immersion Improve Procedure Memorization Performance 

  Bowman, Doug A.; Sowndararajan, Ajith; Ragan, Eric D.; Kopper, Regis (The Eurographics Association, 2009)

  Researchers have proposed that immersion could have advantages for tasks involving abstract mental activities, such as conceptual learning; however, there are few empirical results that support this idea. We hypothesized ...

• A Modular Framework for Distributed VR Interaction Processing 

  Assenmacher, Ingo; Raffin, Bruno (The Eurographics Association, 2009)

  Interactions are a key part of Virtual Reality systems and can lead to complex software assembly for multi-modal and multi-site collaborative environments. This is even harder, when each participant is interacting in the ...

• Desktop Integration in Graphics Environments 

  Ullrich, Torsten; Settgast, Volker; Ofenböck, Christian; Fellner, Dieter W. (The Eurographics Association, 2009)

  In this paper, we present the usage of the Remote Desktop Protocol to integrate arbitrary, legacy applications in various environments. This approach accesses a desktop on a real computer or within a virtual machine. The ...

• Tree-shaded screen: A Propeller type screen for Public Art 

  Kunihiro, Nishimura; Suzuki, Yasuhiro; Tokuda, Yutaka; Iida, Tomohiro; Kajinami, Takashi; Tanikawa, Tomohiro; Hirose, Michitaka (The Eurographics Association, 2009)

  Tree-shaded screen is a novel artwork for the public space. One can also think of it as a novel virtual reality system. The artwork consists of a surround couch, a column, and a propeller with six blades. When we sit down ...

• Multi-scale Manipulation in Indoor Scenes with theWorld in Miniature Metaphor 

  Trueba, Ramon; Andujar, Carlos; Argelaguet, Ferran (The Eurographics Association, 2009)
