Assignee: RAZER (ASIA-PACIFIC) PTE. LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. 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.
