Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. An input device comprising
a housing;
a ring-shaped scroll wheel; and
a haptic unit inserted through the scroll wheel, the haptic unit comprising
a bridging structure,
a fluid based variable motion-resistance component coupled to the bridging structure, the fluid based variable motion-resistance component having a cylindrical body with a first end directed towards the bridging structure, the cylindrical body being rotatable relative to the bridging structure about a longitudinal axis of the cylindrical body, wherein the scroll wheel is fixedly attached to the cylindrical body in a coaxial manner, the fluid based variable motion-resistance component varies a motion-resistance profile against a relative rotation motion between the cylindrical body and the bridging structure based on an input control signal received by the haptic unit for defining a haptic behavior of the scroll wheel,, wherein the haptic unit is mounted to the housing in a manner so as to suspend the haptic unit and the scroll wheel from a portion of the housing.
