Abstract
Electronic devices, such as consumer electronics devices and control systems in vehicles are controlled by way of a haptic operating device with a rotating unit. Selectable menu items are displayed on a display unit, and a menu item is 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 in accordance with a specific menu item selected by the user.
Claims15
A method of operating technical equipment, the method comprising:
- providing a knob with haptic feedback and having a rotary element for manual activation;
- establishing wireless communication between the knob and the technical equipment;
- placing the knob directly on a display screen of the technical equipment and controlling a display on the display screen by rotating the rotary element;
- displaying a menu on the display screen with menu items related to operations of the technical equipment;
- responsive to a manual activation of the rotary element, selecting a menu item from the menu and causing the rotary element to latch at a plurality of haptically perceptible latching points during the rotation;
- and
- dynamically changing a number or an angular position of the haptically perceptible latching points in accordance with the menu;
- providing the haptically perceptible latching points as a dynamically variable, electronically controlled resistance against a rotation of the rotary element effected by a magnetorheological transmission apparatus functionally associated with the rotary element;
- and
- dynamically changing a torque profile of a torque opposing the rotation during the rotation of the rotary element;
- and
- setting a response time of the rotary element to switch from an arbitrary initial torque opposing the rotation of the rotary element to an end torque opposing the rotation to less than 20 milliseconds.
A method of operating technical equipment, the method comprising:
- providing a knob with haptic feedback and having a rotary element for manual activation;
- establishing wireless communication between the knob and the technical equipment;
- displaying a menu with menu items related to operations of the technical equipment;
- responsive to a manual activation of the rotary element, selecting a menu item from the menu and causing the rotary element to latch at a plurality of haptically perceptible latching points during the rotation;
- dynamically changing a number or an angular position of the haptically perceptible latching points in accordance with the menu;
- providing a display unit with a display disposed inside the rotary element of the knob for displaying display contents;
- sensing the rotation of the rotary element;
- and
- rotating display contents on the display of the display unit in an opposite direction from the rotation of the rotary element.
