    • Magic in Augmented Reality 

      Batalha, Joao; Dias, Miguel S. (The Eurographics Association, 2006)
      In this paper we suggest a new approach for playing the "Magic The Gathering" game. This approach allows the user to perform a set of game moves within this popular card game using a Tangible Augmented Reality (AR) ...

    • A Mesh-Particle Model for Fluid Animation 

      Suárez, Nuria; Susín, Antonio (The Eurographics Association, 2006)
      We use our adapted versions of the two most used methods in Computer Fluid Animation, Marker and Cell and Smoothed Particle Hydrodynamics, to develop a new method taking advantage of the calculation speed of the first and ...

    • Perceived Quality of Simplified Polygonal Meshes: Evaluation using Observer Studies 

      Silva, Samuel; Ferreira, Carlos; Madeira, Joaquim; Santos, Beatriz Sousa (The Eurographics Association, 2006)
      The complexity of a polygonal mesh model is usually reduced by applying a simplification method, resulting in a similar mesh having less vertices and faces. Although several such methods have been developed, it is not yet ...

    • Perception-based painterly rendering: functionality and interface design 

      Nunes, Samuel; Almeida, Daniel; Brito, Vera; Carvalho, Joao; Rodrigues, Joao; Buf, J. M. Hans du (The Eurographics Association, 2006)
      Painterly rendering (non-photorealistic rendering or NPR) aims at translating photographs into paintings with discrete brush strokes, simulating certain techniques (im- or expressionism) and media (oil or watercolour). ...

    • Recognizing Hand Gestures with CALI 

      Jota, Ricardo; Ferreira, Alfredo; Cerejo, Mariana; Santos, José; Fonseca, Manuel J.; Jorge, Joaquim A. (The Eurographics Association, 2006)
      Human computer interaction techniques that do not rely on devices are often perceived as more natural by users. Many of these, include hand pose recognition as an interaction technique appealing to users. In this paper we ...

    • Skin Detection for Hand Gesture Interfaces using Assimilative Background 

      Santurde, Jokin; Borro, Diego; Matey, Luis M. (The Eurographics Association, 2006)
      This paper describes the study realized about hand movement capture systems oriented to gesture interfaces. Thanks to this study we have developed a skin colour based hand detection application. The state of the art already ...

    • Transferring Facial Expressions to Different Face Models 

      Orvalho, V. Costa Teixeira; Zacur, Ernesto; Susín, Antonio (The Eurographics Association, 2006)
      We introduce a facial deformation system that helps the character setup process and gives artists the possibility to manipulate models as if they were using a puppet. The method uses a set of labels that define specific ...
