Title:
TACTILE SENSATION PRESENTATION DEVICE, TACTILE SENSATION PRESENTATION SYSTEM, COMPUTER PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/123780
Kind Code:
A1
Abstract:
A tactile sensation presentation device provided with a movable yoke (11) connected to a touch panel (3) and a stationary yoke (6). The tactile sensation presentation device generates an electromagnetic force in the stationary yoke to attract the movable yoke and causes the touch panel to be vibrated by the spring reaction of a leaf spring (12) to present tactile sensation. The tactile sensation presentation device is provided with a clearance distance sensor (10) for measuring a yoke clearance distance that is the distance of clearance in the attraction direction between the stationary yoke and the movable yoke, and a control microcomputer for calibrating the yoke clearance distance measured by the clearance distance sensor while being in a neutral state and controlling, using the calibrated yoke clearance distance, the electromagnetic force generated in the stationary yoke when vibrating the touch panel.
