  • A cost-effective approach for developing application-control GUIs for virtual environments 

    Andújar Gran, Carlos Antonio; Fairén González, Marta; Argelaguet Sanz, Fernando (2006-03)
    Conference lecture
    Open Access
    In this paper we present a new approach for fast development of application-control User Interfaces (UIs) for Virtual Environments (VEs). Our approach allows developers to build sophisticated UIs containing both simple ...
  • Anisomorphic ray-casting manipulation for interacting with 2D GUIs 

    Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (2007-01)
    Article
    Open Access
    The accommodation of conventional 2D GUIs with virtual environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ...
  • Automatic speed graph generation for predefined camera paths 

    Argelaguet Sanz, Fernando; Andújar Gran, Carlos Antonio (Springer Verlag, 2009)
    Conference report
    Restricted access - publisher's policy
    Predefined camera paths are a valuable tool for the exploration of complex virtual environments. The speed at which the virtual camera travels along different path segments is key for allowing users to perceive and ...
  • Complexity and occlusion management for the World-in-Miniature Metaphor 

    Trueba Hornero, Ramón; Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (Springer Verlag, 2009)
    Conference report
    Restricted access - publisher's policy
    he World in Miniature (WIM) metaphor allows users to interact and travel efficiently in virtual environments. In addition to the first-person perspective offered by typical VR applications, the WIM offers a second dynamic ...
  • Friction surfaces: scaled ray-casting manipulation for interacting with 2D GUIs 

    Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (2006-05-17)
    Conference report
    Open Access
    The accommodation of conventional 2D GUIs with Virtual Environments (VEs) can greatly enhance the possibilities of many VE applications. In this paper we present a variation of the well-known ray-casting technique for fast ...
  • Improving 3D selection in VEs through expanding targets and forced disocclusion 

    Argelaguet Sanz, Fernando; Andújar Gran, Carlos Antonio (Springer Verlag, 2008-08-27)
    Conference report
    Restricted access - publisher's policy
    In this paper we explore the extension of 2D pointing facilitation techniques to 3D object selection. We discuss what problems must be faced when adapting such techniques to 3D interaction on VR applications, and we propose ...
  • Improving co-located collaboration with show-through techniques 

    Argelaguet Sanz, Fernando; Kunert, André; Kulik, Alexander; Froehlich, Bernd (2010-03-20)
    Conference report
    Open Access
    Multi-user virtual reality systems enable natural interaction with shared virtual worlds. Users can talk to each other, gesture and point into the virtual scenery as if it were real. As in reality, referring to objects by ...
  • Multi-scale manipulation in indoor scenes with the World in Miniature Metaphor 

    Trueba Hornero, Ramón; Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (2009)
    Conference report
    Restricted access - publisher's policy
    The World in Miniature Metaphor (WIM) allows users to select, manipulate and navigate efficiently in virtual environments. In addition to the first-person perspective offered by typical VR applications, the WIM offers a ...
  • Pointing facilitation techniques for 3d object selection on virtual environments 

    Argelaguet Sanz, Fernando (Universitat Politècnica de Catalunya, 2011-07-04)
    Doctoral thesis
  • See-through techniques for referential awareness in collaborative virtual reality 

    Argelaguet Sanz, Fernando; Kulik, Alexander; Kunert, André; Andújar Gran, Carlos Antonio; Froehlich, Bernd (2011)
    Article

    Multi-user virtual reality systems enable natural collaboration in share virtual worlds. Users can talk to each other, gesture and point into the virtual scenery as if it were real. As in reality, refer ring to objects ...
  • Visual feedback techniques for virtual pointing on stereoscopic displays 

    Argelaguet Sanz, Fernando; Andújar Gran, Carlos Antonio (2009)
    Conference report
    Restricted access - publisher's policy
    The act of pointing to graphical elements is one of the fundamental tasks in Human-Computer Interaction. In this paper we analyze visual feedback techniques for accurate pointing on stereoscopic displays. Virtual feedback ...
  • World-in-miniature interaction for complex virtual environments 

    Trueba Hornero, Ramón; Andújar Gran, Carlos Antonio; Argelaguet Sanz, Fernando (IGI Global, 2010-12)
    Article
    Open Access
    Object occlusion is a major handicap for efficient interaction with 3D virtual environments. The well-known World in Miniature (WIM) metaphor partially solves this problem by providing an additional dynamic view point ...
