    • NavTilt: Interface Gestual para Cegos 

      Lucas, David; Nicolau, Hugo; Guerreiro, Tiago; Jorge, Joaquim (The Eurographics Association, 2021)
      A crescente miniaturização dos dispositivos móveis e as suas interfaces visualmente exigentes impõem diversos desafios à população cega. Em particular, os métodos de introdução de texto tradicionais mostram-se desadequados ...
    • Näprä - Affordable Fingertip Tracking with Ultrasound 

      Reunanen, M.; Palovuori, K.; Ilmonen, T.; Mäkelä, W. (The Eurographics Association, 2005)
      In this paper we present Näprä, a novel tracking device suitable for fine motor interaction. The motivation for building the device was the need to track users' fingertips in an immersive free-hand drawing environment. ...
    • NCGA’82 

      Kuhlmann, H W (Blackwell Publishing Ltd and the Eurographics Association, 1982)
    • Near Light Correction for Image Relighting and 3D Shape Recovery 

      Huang, Xiang; Walton, Marc; Bearman, Greg; Cossairt, Oliver (IEEE, 2015)
      In this paper, we propose a near-light illumination model for image relighting and 3D shape recovery. Classic methods such as used by the popular RTI software from Cultural Heritage Imaging assume that lighting is infinitely ...
    • Near Optimal Hierarchical Culling: Performance Driven Use of Hardware Occlusion Queries 

      Guthe, Michael; Balázs, Ákos; Klein, Reinhard (The Eurographics Association, 2006)
      The most efficient general occlusion culling techniques are based on hardware accelerated occlusion queries. Although in many cases these techniques can considerably improve performance, they may still reduce efficiency ...
    • Near-correct Ocular Accommodation Responses to a 3d Display, Using Multiple Image Planes and Depth Filtering 

      MacKenzie, Kevin J.; Watt, Simon J. (The Eurographics Association, 2009)
      Conventional stereo displays provide incorrect focus cues because the image is presented on a single surface. This is known to cause a number of aversive symptoms in users, including fatigue and discomfort. Multiple-focal-plane ...
    • Near-Eye Display and Tracking Technologies for Virtual and Augmented Reality 

      Koulieris, George; AKSIT, KAAN; Stengel, Michael; Mantiuk, Rafał K.; Mania, Katerina; Richardt, Christian (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Virtual and augmented reality (VR/AR) are expected to revolutionise entertainment, healthcare, communication and the manufacturing industries among many others. Near-eye displays are an enabling vessel for VR/AR applications, ...
