Abstract
A hubless scroll wheel for a computer peripheral device may include a wheel defining an open interior. The wheel may include a plurality of contactless indexing features positioned at different angular positions. The scroll wheel may include at least one fixed contactless ratchet member disposed within the open interior of the wheel. The wheel may be rotatable relative to the fixed contactless ratchet members. Each contactless indexing feature and fixed contactless rachet member may include one or both of a magnet and a ferromagnetic material. fixed contactless rachet members may be configured to interact with the contactless indexing features to produce a tactile response as the wheel is rotated. The scroll wheel may include at least one sensor that is configured to detect a magnitude and direction of rotation of the wheel relative to the fixed contactless ratchet members.
