Synthesizing Friction In A Force-Reflecting Hand Controller
Algorithm synthesizes frictionlike limited reaction force in force-reflecting hand controller. Synthetic friction enhances operator's feel and improves control characteristics in two ways: handle of controller retains setting when operator releases it, and in case of multiple-axis controller, synthetic frictional force helps to hold control setting on one axis when handle pushed to command movement along another axis.
