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.

First claim

The invention claimed is:

1. A method of adjusting a smart device, the method comprising:
providing a knob with haptic feedback and having a rotary element for manual activation;
encoding a rotation of the rotary element upon a manual activation thereof with a rotary encoder;
establishing wireless communication between the haptic knob and the smart device;
controlling an input of the smart device in accordance with the manual activation of the rotary element and setting a property of the rotary element in accordance with a currently selected menu on the smart device;
providing a display unit with a display disposed inside the rotary element of the knob for displaying display contents;
sensing a rotation between the rotary element and a basic body of the knob; and
rotating display contents on the display of the display unit in an opposite direction from the rotation of the rotary element.

2. The method according to claim 1 , which comprises supplying the knob with energy by inductive coupling or by acquiring the energy required for an operation of the knob by an energy harvesting process.

3. The method according to claim 1 , wherein the property of the rotary element is a resistance against a rotation thereof and wherein the resistance is dynamically variable to thereby provide haptic feedback to a user controlling the smart device.

4. The method according to claim 3 , wherein the dynamically variable resistance is provided by an electronically controlled resistance against a rotation of the rotary element.

5. The method according to claim 4 , wherein the electronically controlled resistance is provided by driving a magnet device or an electrical device that converts to a mechanical feedback or mechanical resistance of the rotary element.

6. The method according to claim 4 , wherein the electronically controlled resistance is provided by a magnetorheological transmission apparatus functionally associated with the rotary element.

7. The method according to claim 1 , wherein the smart device has a display screen and the method comprises placing the knob directly on the display screen and controlling a display on the display screen by rotating the rotary element.
