Publication number: 20190317544Abstract: A knob includes a support structure defining a chamber containing magnetorheological fluid. A holding element is supported and guided by the support structure to be rotated and pressed by the user. A movable portion is rotatably supported by the support structure and is rotatably controlled by the holding element. A switching member moves between rest and work positions when the holding element is pressed. A sensor detects the angular position of the movable portion. A haptic feedback assembly in the chamber acts upon the movable portion to provide haptic stimulation in response to action of the user. A generating apparatus emits a magnetic field with an intensity affecting viscosity of the fluid so the assembly exerts a force upon the movable portion. A control device determines the intensity of the magnetic field depending on predetermined or programmable criteria that are based on angular position and/or arrangement.Type: ApplicationFiled: November 30, 2017Publication date: October 17, 2019Inventors: Paolo Ravedati, Paolo DA PONT, Marco Becchio, Matteo Chiapparino
