Abstract
An input device includes a magnet to be worn by a user on one fingertip of either a right hand or a left hand, a first magnetic sensor to be worn by the user on a wrist of either the right hand or the left hand to detect a magnetic field generated by the magnet at a corresponding position, a second magnetic sensor to be worn by the user on the same wrist on which the first magnetic sensor is worn and at a position that is farther from the magnet than the first magnetic sensor and eliminates effects of geomagnetism, and an output unit to output a difference between an output signal from the first magnetic sensor and an output signal from the second magnetic sensor.
