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.
Claims11
A haptic interface, comprising:
- a rotary element to be manually activated;
- an integrated rotary encoder associated with said rotary element and disposed to interpret a rotation of said rotary element upon manual activation thereof;
- and
- a display unit with a display for displaying a given selected menu;
- wherein at least one property of the haptic interface changes depending on a currently selected menu,
- wherein the at least one property of the haptic interface is a resistance of said rotary element against rotation thereof, and the resistance is variably set to provide a haptic feedback to the manual activation of said rotary element and in accordance with the currently selected menu;
- a sensor disposed to sense an angle change or an absolute angular position between said rotary unit and a basic body of a device to be controlled with the haptic interface;
- and
- a control device configured to rotate the display of said display unit in an opposite direction based on a signal from said sensor.
