Virtual Peg-in-Hole Performance Using a 6-DOF Magnetic Levitation Haptic Device: Comparison with Real Forces and with Visual Gui
We describe two experiments using three testbeds (real, virtual and vision-only) for comparison of user performance during 3-D peg-in-hole tasks. Tasks are performed using a six-d...
