Abstract
There is provided a tactile feedback device comprising: an array of surface charge generation units; and an array of pressure-generation units, wherein the array of the pressure-generation units is spaced apart from the array of the surface charge generation units, wherein the array of the pressure-generation units is movable relative to the array of the surface charge generation units, wherein an attractive or repulsive force is generated between a corresponding surface charge generation unit of the array of surface charge generation units and a corresponding pressure-generation unit of the array of the pressure-generation units, based on a polarity of surface charges induced in the corresponding surface charge generation unit.
