The I-space at the Erasmus MC is driven by an Onyx4 UltimateVision, and has stereo glasses and a flightstick for navigation and interaction. Artm and Brigit wrote GATC/life in C, using the SGI OpenGL Performer API. To handle user input, tracking, and stereo projections we used FreeVR, which is an open-source virtual reality interface/integration library.
Interaction between the participant and the software in I-Space is established with:
- Head tracking: the primary pair of stereo glasses
bears a markup which is being tracked by cameras.
This allows the application to know the position and
view direction of the participant.
- Flystick: the primary participant holds in a hand a
wireless analog of a joystick, which is being tracked
in 3D space as well as contains extra controls (buttons and mini-joystick adding another two axis of freedom). Mini joystick allows to navigate in the
environment while buttons allow to switch the
environments and interact with the flocks of cells.
