Abstract
Apparatus and method for operating vehicles and other technical equipment by way of a haptic operating device having a rotating unit. Selectable menu items are displayed on a display unit, and a menu item being selected by rotating the rotating unit. The rotating unit latches at a number of haptically perceptible latching points during rotation. The number and rotational position of the haptically perceptible latching points is dynamically changed.
Claims7
A method of operating technical equipment, the method comprising:
- providing a haptic operating device having a rotating unit and a display unit displaying selectable menu items;
- rotating the rotating unit to select a menu item from the menu items;
- causing the rotating unit to latch at any of a plurality of haptically perceptible latching points during rotation;
- and
- dynamically changing a number of the haptically perceptible latching points in dependence on the selectable menu items displayed on said display unit;
- generating the latching points by deliberately generating a magnetic field at a channel at least partially filled with a magnetorheological medium;
- and
- dynamically generating an end stop in at least one direction of rotation, and thereby setting the magnetic field considerably stronger at the end stop than at a latching point.

A method of operating technical equipment, the method comprising:
- providing a haptic operating device having stationary unit, a rotating unit rotatably mounted relative to the stationary unit, and a display unit displaying selectable menu items;
- rotating the rotating unit to select a menu item from the menu items;
- causing the rotating unit to latch at any of a plurality of haptically perceptible latching points during rotation;
- and
- dynamically changing a number of the haptically perceptible latching points in dependence on the selectable menu items displayed on the display unit;
- and
- dynamically generating an end stop in at least one direction of rotation, the end stop having a considerably stronger resistance against rotation that any of the latching points.
