Title:
INPUT DEVICE AND INPUT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/187246
Kind Code:
A1
Abstract:
This input device comprises: an operation body; a rotor for operation body operation; a magnetic viscous fluid that comes into contact with the rotor; and a magnetic field generation unit that applies a magnetic field to the magnetic viscous fluid. The magnetic viscous fluid generates resistance for suppressing the rotation of the rotor by contacting the rotor. The magnetic field generation unit changes the viscosity of the magnetic viscous fluid by applying a magnetic field to the magnetic viscous fluid, thereby changing the magnitude of resistance. The magnetic field generation unit has a plurality of coils that each apply a magnetic field to the magnetic viscous fluid.
