An information presentation device transmits information of a car navigation system, installed in a vehicle, to a driver in form of tactile stimuli, wherein a controller controls a plurality of vibrators attached to a steering wheel. The vibrators are arranged in proximity to vibration transmitters, corresponding to holding parts of a steering wheel, so that they are controlled with desired vibration intensity and vibration start timing in response to drive signals from the controller. Two vibrators are arranged in the holding parts of a steering wheel which come in contact with driver's hands and are controlled to generate a virtual vibrating source, thus rendering a driver feeling a sensation as if a vibrating source is moving in upward-downward directions, left-right directions, and far-near directions in the front side of a driver. Thus, it is possible to present accurate information with a small amount of energy consumption in driving vibrators.
