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.
Claims8
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;
- 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;
- wherein the dynamically variable resistance is provided by an electronically controlled resistance against the rotation of the rotary element;
- and
- wherein 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 is less than 20 milliseconds.
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;
- 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.
