Abstract
Disclosed herein is an input device that replicates mechanical actuation of a rotatable input mechanism in such a way that the haptic output provided by the input device is controllable.
Claims20
A rotatable input mechanism, comprising:
- a rotatable structure;
- a surface within the rotatable structure;
- a moveable mass;
- and
- an actuation mechanism that causes the moveable mass to engage and disengage the surface, thereby dynamically changing a torque required to rotate the rotatable structure.
2 more elements
A user-manipulable rotatable input mechanism, comprising:
- a rotatable structure configured to rotate about an axis;
- and
- an actuation mechanism defining an engagement surface;
- wherein
- the engagement surface is configured to alternately contact and disengage from the rotatable structure, thereby varying friction between the engagement surface and the rotatable structure to provide a varying haptic output.
2 more elements
An input device, comprising:
- a cover;
- a feedback mechanism coupled to an inner surface of the cover;
- and
- a rotating center plate operable to rotate both with the cover and independently of the cover, and having one or more detents disposed on a perimeter that interact with the feedback mechanism to provide a variable haptic output.
