Abstract
A tactile sensation providing apparatus capable of providing a constant tactile sensation to a user regardless of a position of a touch input is provided. According to the present invention, the tactile sensation providing apparatus has a touch sensor configured to detect the touch input, a load detection unit configured to detect a pressure load on a touch face of the touch sensor, a tactile sensation providing unit configured to vibrate the touch face, and a control unit configured to control drive of the tactile sensation providing unit based on a pushed position, when the pressure load detected by the load detection unit satisfies a standard to provide a tactile sensation, such that the tactile sensation is provided to an object pressing the touch face by vibration with certain amplitude independent of the pushed position.
