Abstract: There is disclosed a movement sensing device configured to detect movement of an object on a touch region three or more proximity sensors arranged on one surface adjacent to the touch region independently and two-dimensionally, to measure electrical scalars corresponding to distances with the object on the touch region, respectively; and a control unit configured to calculate a vector of a second touch point relatively changed with respect to a first touch point based on a first electrical scalar and a second electrical scalar measured at a predetermined time difference, wherein a relative moving signal with respect to a reference point is generated by calculating the movement of the object as the vector.
