Abstract
A tactile presentation device includes a touch surface fixed in orientation, an actuator configured to vibrate the touch surface along one axis within the plane of the touch surface, and a controller configured to control vibration of the actuator along the one axis to present tactile stimulus to a finger in contact with the touch surface. The controller is configured to control the actuator in such a manner that direction to start vibration for presenting tactile stimulus to the finger is within a range from minus 43° to plus 43° with respect to a direction of gravity projected on the touch surface or the opposite direction thereof.
