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.

A tactile presentation device comprising:
- 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,
- wherein 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.
A tactile presentation device comprising:
- a touch surface;
- 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,
- wherein the controller is configured to:
- presume orientation of the finger in contact with the touch surface projected on the touch surface;
- and
- control the actuator in such a manner that intensity of the vibration changes depending on the projected orientation.
A tactile presentation device comprising:
- a touch surface;
- a display device fixed in a relative position to the touch surface;
- 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,
- wherein 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 from the top to the bottom of an image displayed on the display device or the opposite direction thereof.
