Abstract: In certain embodiments, an electronic input device includes a knob assembly defining an annular cavity and including a magnetically attractable armature. The electronic input device also includes a ratchet assembly disposed within the annular cavity and includes a ring magnet. The electronic input device includes a clutch mechanism that has a friction disc assembly, and an electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly prevents rotation of the ratchet assembly and a second position in which the ratchet assembly is free to rotate with the knob assembly. The ring magnet of the ratchet assembly interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.

Abstract: A knob for an input device includes a knob housing being rotatable on an axis, a shaft extending from the knob housing along the axis, a ratchet wheel axially coupled to the shaft with a toothed perimeter, and a ratchet arm to couple to the toothed perimeter of the ratchet wheel when the ratchet arm is engaged such that a ratcheted rotation occurs when the knob is rotated, and decouple from the toothed perimeter of the ratchet wheel when the ratchet arm is disengaged. The knob can further include a resistance wheel axially coupled to the shaft with a substantially smooth perimeter, and a resistance arm to couple to the smooth perimeter of the resistance wheel when the resistance arm is engaged such that a friction is provided when the knob is rotated, and decouple from the smooth perimeter of the resistance wheel when the resistance arm is disengaged.

Abstract: In certain embodiments, a computer-implemented method includes detecting a selectable control element on a graphical user interface (GUI), determining an editable parameter associated with the selectable control element, associating a control of the editable parameter with a user-manipulable element on an input device, and generating and sending, to the input device, control data causing the input device to assign a performance characteristic to the user manipulable element based on properties of the editable parameter. In some aspects, the user manipulable element can be a rotatable knob on the input device. The performance characteristic may include a rotation resistance of the knob, a rotational input resolution of the knob (e.g., rotation sensitivity), setting a ratchet or non-ratchet mode of operation to the knob based on the properties of the editable parameter (e.g., by controlling an electro-magnetic actuator to set the ratchet or non-ratchet modes), or a depressible knob.
