This paper describes simple tactile presentation system for VR using magnetic field. Small devices that present a tactile sensation and can easily be mounted on skin have been proposed by attaching a magnet to a fingertip and setting a remote driving coil on the environment. However, such devices have been used only at a distance of several centimeters from the coil. We show that a coil of practical size and power consumption can convey sufficient vibration for tactile presentation at a distance of 50 cm or more, and two magnets can be driven almost independently by using multiple coils.
