Training in Virtual Reality

5
Limitations with Current VR
Inclusion of haptics adds huge computational cost
3 Degrees of Freedom (DOF) - Translations
6 Degrees of Freedom (DOF) - Translations and
rotations
6
Importance/Benefits of 6DOF

My Work
6 DOF implementation - tweezers - needle
and needle clamps
Assessment - accuracy of simulator -
usefulness of simulator
Extensions - Calcifications - Two-handed
simulators
