Patent ID: 11876428

Abstract:
An operation on a vibration device presenting a force sense based on vibration to a human body is simplified. The vibration device includes: a base mechanism; an actuator configured to perform a physical motion based on a supplied control signal; a slide mechanism configured to perform a periodic reciprocating slide motion in a predetermined direction and an opposite direction to the predetermined direction with respect to the base mechanism based on the physical motion of the actuator and to give a force based on the reciprocating slide motion to a part of a human body with which the slide mechanism comes into direct or indirect contact; and a detection unit located in the predetermined direction with respect to the slide mechanism and configured to detect displacement of a specific portion included in the slide mechanism. The specific portion is movable in the predetermined direction by a width greater than an amplitude at the time of the reciprocating slide motion when a force is given to the slide mechanism from the part of the human body with which the slide mechanism comes into direct or indirect contact. Driving control is performed on the actuator when the detection unit detects the specific portion moved in the predetermined direction by the width greater than the amplitude at the time of the reciprocating slide motion.
