Abstract
Disclosed is a tactile presentation apparatus including a plurality of tactile cells. Each of the plurality of tactile cells includes a supporter for shielding magnetic force, a tactile feeder moving up according to the magnetic force in the supporter, and an electromagnet generating magnetic force depending on depth information of a pixel. The tactile presentation apparatus includes a permanent magnet, a vibration device that vibrates according to texture information, and a pressure sensor measuring pressure applied to the tactile feeder.
