Abstract
The present invention relates to a magnetic apparatus for providing a tactile sensation and, more particularly, to a magnetic apparatus for providing a user with tactile information, by means of changes in viscosity, rigidity and elasticity due to a magnetic field, by using a magnetorheological fluid or a magnetorheological elastiomer. A magnetic apparatus for providing a tactile sensation comprises a tactile sensation provider 110 having magnetic particles 101, wherein the tactile sensation provider 110 provides a user with tactile information by means of a change due to an external magnetic field that has been applied.
Claims5
A magnetic apparatus for providing a tactile sensation, the apparatus comprising:
- a tactile sensation provider, and
- a magnetic field generator for generating a magnetic field, the magnetic field being applied to the tactile sensation provider,
- wherein the tactile sensation provider includes,
- an outer cover, at least part of the outer cover being made of an elastic body, and
- a magnetorheological fluid sealed in an inner space of the outer cover, the magnetorheological fluid being a suspension of magnetic particles,
- wherein the tactile sensation provider provides vibrational sensations to a user when an alternating current magnetic field is generated by the magnetic field generator, and
- wherein the tactile sensation provider provides sensations based on change in rigidity to a user when a direct current magnetic field is generated by the magnetic field generator.
