Platform for setting up interactive virtual environments

Danilo Souza, Paulo Dias, Daniel Santos, Beatriz Sousa Santos, Margaret Dolinsky, Ian E. McDowall
2014 The Engineering Reality of Virtual Reality 2014  
Alongside its development, a comparative study between two ray-tracing selection techniques was performed.  ...  The platform allows users, from a configuration tool, to create virtual environments and set up their aspects, modes of interaction and what hardware to use.  ...  These adaptations of ray-cast are called Gaze-Based Selection and Laser Pointer Selection (Mine, 1995) . The indication to select would be done the same way as travelling, by pressing a button.  ...
