Input device

An input device comprising

• a housing;
• a ring-shaped scroll wheel;
• and
• an integrated haptic unit inserted through the scroll wheel, the integrated haptic unit comprising
• a bridging structure,
• a variable motion-resistance component coupled to the bridging structure, the variable motion-resistance component being rotatable relative to the bridging structure about a rotational axis, wherein the scroll wheel is fixedly attached to the variable motion-resistance component in a coaxial manner with respect to the rotational axis, wherein the variable motion-resistance component varies a motion-resistance profile against a relative rotation motion between the variable motion-resistance component and the bridging structure based on an input control signal received by the integrated haptic unit for defining a haptic behavior of the scroll wheel, and
• an encoder built into the bridging structure to convert an angular displacement or motion between the variable motion-resistance component and the bridging structure as an output signal from the integrated haptic unit,
• wherein the integrated haptic unit is mounted to the housing in a manner so as to suspend the integrated haptic unit and the scroll wheel from a portion of the housing.
