A Conceptual Design of a Smart Knob with Torque Feedback for Mobile Applications

This study proposes a conceptual design of a tiny smart knob based on MR fluids in order to convey realistic haptic feedback to users in mobile devices. The haptic sensation, which is created in the form of resistive torque, is varied according to the current input. The proposed knob is designed in small size as possible as can so that it is easily inserted into mobile devices.
