Abstract: Provided is a magnetorheological rotating load apparatus and a control method therefor, the magnetorheological rotating load apparatus including a housing, a yoke fixed in the housing, a shaft mounted to rotate in the housing, at least one rotating ring connected to the shaft to rotate in conjunction with the rotation of the shaft, a coil disposed in the housing, and a magnetorheological fluid filled in at least a portion of the housing, wherein at least a portion of the shaft positioned inside the housing is made of a non-magnetic material.

Abstract: The present invention relates to a tactile keyboard and a tactile input device. The tactile keyboard according to the present invention, which includes a plurality of keys, comprises a base portion providing a region on which the plurality of keys are arranged, wherein at least one of the keys comprises: a magnetic field generator which is arranged on the base portion; a cap portion which provides one surface so that a user comes in contact with the surface to apply an external force; an elastic portion which is disposed between the base portion and the cap portion and elastically supports the cap portion; and a motion portion which is at least partially connected to the cap portion and includes an elastic material, in which magnetic particles are distributed in a matrix.

Abstract: Provided is a haptic device including a medium for receiving a digital sound signal from a portable terminal, a digital-to-analog converter (DAC) for receiving the digital sound signal from the medium and converting the digital sound signal into an analog signal, a sound outputter for receiving the analog signal and outputting sound, and a haptic actuator driven by receiving the analog signal.
