Abstract

Electronic devices, such as consumer electronics devices and constrol 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

1 . A method of adjusting a smart device, the method comprising:
providing a haptic feedback device with a rotary element for manual activation, the haptic feedback device containing an energy storage device and being configured for inductive charging; establishing wireless communication between the haptic feedback device and the smart device; encoding a rotation of the rotary element upon a manual activation thereof with a rotary encoder; 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.

2 . The method according to claim 1 , which comprises supplying the haptic feedback device with energy by inductive coupling and by additionally acquiring energy required for an operation of the haptic feedback device by an energy harvesting process.

3 . The method according to claim 1 , wherein the smart device has a display screen and the method further comprises:
placing the haptic feedback device directly on the display screen of the smart device and operating the rotary element with the haptic feedback device disposed on the display screen.

4 . The method according to claim 1 , further comprising:
providing the haptic feedback device with a display unit having a display disposed inside the rotary element; sensing a rotation being an angle change of the rotary element; and rotating display contents on the display of the display unit in an opposite direction of the angle change to thereby retain the display contents stationary relative to the smart device.

5 . 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.

6 . The method according to claim 5 , wherein the dynamically variable resistance is provided by an electronically controlled resistance against a rotation of the rotary element.

7 . The method according to claim 6 , 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.

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