Abstract
Provided is a pseudo force sensation providing device that can accurately measure an external magnetic field despite a small size thereof. Provided is a pseudo force sensation providing device including: an electrical actuator that performs physical movement based on a control signal supplied thereto; a contact mechanism that performs periodic asymmetric movement that causes a user to perceive pseudo force sensation, based on physical movement of the actuator; a magnetic sensor that measures an external magnetic field; and a shielding member that is provided between the actuator and the magnetic sensor, and surrounds a portion of the actuator on the side of the magnetic sensor, to block a magnetic field on the side of the magnetic sensor generated by the actuator.
