Title: APPARATUS FOR GENERATING TACTILE SENSATION
Abstract:
Disclosed is an apparatus for generating a tactile sensation. An apparatus for generating a tactile sensation according to a first embodiment of the present invention comprises: a tactile sensation generating unit including a magnetorheological fluid, the shape of which changes according to a magnetic field and which comes in contact with a user's body so as to allow the user to feel a tactile sensation according to a change in the shape, and a first magnet which is arranged to be surrounded with the magnetorheological fluid, which increases the amount of change of the magnetorheological fluid by the magnetic field thereof, and the position of which changes according to a change in a magnetic field generated by an external source; a magnetic field forming unit for selectively forming a magnetic field around the tactile sensation generating unit; and a control unit which outputs a signal for forming a magnetic field to the magnetic forming unit when a user's body in contact with the tactile sensation generating unit reaches the surface of a virtual object.
