PRIME students at NICT and Osaka University collaborated on the Opencover plugin called Navi to permit interaction with a 3D model of an Osaka nightlife area rendered on NICT's NexCAVE virtual reality environment.
Based at different institutions (NICT and Osaka University, respectively), we worked together on a project called Navi: Covise-Kinect Navigation Interface. Kinect is a motion-capture device sold by Microsoft with their game engine; COVISE – Collaborative Visualization and Simulation Environment – is an extendable distributed software environment to integrate simulations, post-processing and visualization functionalities. In this project, we created a navigation plug-in to interface a Kinect device with COVISE to enable users to explore a Virtual Reality Modeling Language (VRML) model through movements and gestures. We also tackled and resolved problems with flickering and texture exportation on a large-scale model made by Kansai University of old Osaka Doutonbori, the most popular entertainment district in Osaka. The plug-in we created was combined with a viewpoint plug-in to make it easier to reset and change views, and we combined it with a texture optimization plug-in. Navi works well on the NexCAVE system at the NICT Keihanna Research Center. The Navi system was successfully shown at the Knowledge Capital Trial 2011 technology exhibition for the North Umeda district project. More than 12,000 visitors attended the exhibition in Osaka.
