Information presentation device

An information presentation device comprising:

• a directional information obtaining element for obtaining directional information based on a signal from an enhancement device, wherein the enhancement device enhances safety or comfort of a passenger of a vehicle, and at least a part of the enhancement device is disposed in the vehicle;
• an information presentation controller for generating a driving signal based on the directional information;
• a stimulation element including a plurality of vibrators, each of which is operated based on the driving signal so that the vibrator generates a traveling wave of vibration in an in-vehicle element, wherein the passenger touches the in-vehicle element;
• and
• a touch detector disposed in the in-vehicle element,
• wherein
• a directionality of the traveling wave corresponds to the directional information, the stimulation element transmits the traveling wave to the passenger so that the passenger perceives the directionality of the traveling wave,
• the information presentation controller outputs the driving signal when the touch detector detects that the passenger is capable of perceiving the traveling wave,
• the stimulation element is disposed in the in-vehicle element,
• the in-vehicle element is a direction change operation unit for operating a driving direction of the vehicle,
• the plurality of vibrators is separated from each other by a predetermined distance, and the plurality of vibrators is coupled with each other via a vibration transmit member so that the passenger perceives the traveling wave through the vibration transmit member, and
• the vibration transmit member is made of a metal or hard resin material that bridges between the vibrators which are separated and spaced apart, the vibration transmit member being configured to transmit the traveling wave as vibration between the vibrators.
