This demo presents a desktop VR system for evaluating human performance in 3D pointing tasks. The system supports different input devices (e.g., mouse and 6DOF remote pointer), pointing techniques (e.g., screen-plane and depth cursors), and cursor visualization styles (e.g., one-eyed and stereo 3D cursors). The objective is to comprehensively compare all combinations of these conditions. We especially focus in on fair and direct comparisons between 2D and 3D pointing tasks. Finally, our system includes a new pointing technique that outperforms standard ray pointing.
