Abstract:
An electronic device, such as a watch, has a variable friction mechanism for providing variable frictional feedback as an input mechanism, such as a crown, is rotated. The variable frictional feedback may correspond to operational states, events, or other conditions at the electronic watch. The variable frictional feedback may be provided by changing a frictional force between the crown and the variable friction mechanism. The variable friction mechanism may include a friction element adapted to contact a shaft of the crown and an actuator adapted to change a frictional force between the friction element and the shaft.
