PURPOSE: An interface method and an interface device for non-contact touch input and haptic output using magnetic force are provided to reduce abrasion and friction due to a mechanical vibration of the device by performing non-contact input and haptic output. CONSTITUTION: A magnetic force generator(605) generates magnetic force. A variable magnetic force generator(610) receives a current and generates a repulsive force with regard to the magnetic force generator. A pressure sensor(615) senses the repulsive force. A pulse current generator(625) generates a pulse current. A pulse current output unit(630) supplies the pulse current to the variable magnetic force generator. A controller(620) controls the pulse current generator and the pulse current output unit according to the signal of the pressure sensor. |
