    • 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 ...
    • NetVis: a Visualization Tool Enabling Multiple Perspectives of Network Traffic Data 

      Nicholls, James; Peters, Dominik; Slawinski, Albert; Spoor, Thomas; Vicol, Sergiu; Happa, Jassim; Goldsmith, Michael; Creese, Sadie (The Eurographics Association, 2013)
