Haptic scroll wheel input device
A recently granted patent (Publication Number: US11899858B2) discloses an innovative input device featuring a ring-shaped scroll wheel with an integrated haptic unit. The device comprises a housing, a variable motion-resistance component, and an encoder built into the bridging structure to convert motion into an output signal. The haptic unit is mounted in a manner that suspends the scroll wheel from the housing, allowing for a unique haptic behavior defined by an input control signal received by the integrated haptic unit. The variable motion-resistance component, with a cylindrical body rotatable relative to the bridging structure, plays a crucial role in varying the motion-resistance profile for an enhanced user experience.
Furthermore, the patent details the mounting mechanism of the integrated haptic unit to the housing, involving a bracket with sockets to receive different components of the device. The bracket's design allows for pivotability about the longitudinal axis, enhancing the functionality of the input device. Additionally, the patent mentions the inclusion of a lighting unit for illuminating the scroll wheel, further enhancing the user experience. The device also features a fluid-based variable motion-resistance component that utilizes magnetorheological fluid or electrorheological fluid to vary the motion-resistance profile based on an input control signal, providing a unique haptic feedback mechanism for users interacting with the scroll wheel.
