Abstract
An operating device with haptic response for the manual entering of information into a device comprises a setting member having a position which is variable under the action of an actuating force, and with which there is connected a transducer for producing electric signals which characterize the position of the setting member. There is connected with the setting member a braking element which, under control by the electric signals, exerts a force on the setting member, the value of which force depends on the position of the setting member. The braking element has at least two surfaces which are movable relative to each other and between which there is provided a force transmitting fluid the transmission properties of which can be varied by the electric signals.
Claims27
An operating apparatus with haptic response for a manual entering of information into a device, the apparatus comprising:
- a setting member, a position of the setting member being variable under the action of an actuating force;
- a transducer which is connected to the setting member for producing electric signals which characterize the position of the setting member;
- and
- a braking element which is connected to the setting member and, under control by the electric signals, exerts a force on the setting member, a magnitude of the force depending on the position of the setting member;
- wherein the brake element has at least two surfaces which are movable relative to each other, and force transmitting means capable of exerting a force between said at least two surfaces, said force transmitting means being a force transmitting fluid or a force transmitting element having force transmission properties which are variable in response to the electric signals.
