By manipulating a handle that is levitated by magnetic means, users can translate and rotate the handle while feeling forces and torques from the virtual environment. All the actuators, connectors, cables, bearings whose add additional forces to the traditional haptic devices are gone because of the direct electrodynamic connection to the handle. That is a easy way to achieve the following advantages:
- Single moving part with 6 degrees of freedom
- Zero static friction
- Zero mechanical backlash
- ......
