Schematic representation of the virtual shuffleboard game.

The participant moves a manipulandum along a linear bearing. Position and acceleration data from the manipulandum is used to move a virtual shuffleboard cue that pushes a puck towards a target in the virtual world. The various parts of of setup are: (1) accelerometer; (2) LVDT (position sensor); (3) linear, low friction bearing; (4) data acquisition board; (5) control computer running LabVIEW (for data acquisition) and C++ modules (for graphics rendering and physics logic); (6) projector; (7) virtual environment projected on a screen.
