User interface device and method of controlling tactile presentation

Abstract

A user interface device includes a knob device having a mechanical structure that presents a tactile stimulus in response to every predetermined amount of knob operation, a panel on which the knob device is mounted, a controller, and a vibration generator configured to vibrate the knob device, the vibration generator being controllable by the controller. The controller controls the vibration generator to make the knob device vibrate synchronously with the predetermined amount of knob operation for the knob device to present a tactile stimulus in addition to the tactile stimulus by the mechanical structure.
