Abstract
An input device comprises a housing, and a user-movable roller having an exposed portion exposed from the housing. The roller is rotatable in a first rotational direction to generate first rotational signals. A first user-manipulable button is exposed from the housing for contact by a user and configured to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals when pressed and maintained in a pressed position. In some embodiments, the roller is rotatable in a second rotational direction opposite from the first rotational direction to generate second rotational signals. A second user-manipulable button is exposed from the housing for contact by the user and configured to simulate rotation of the roller in the second rotational direction and generate the second rotational signals when pressed and maintained in a pressed position.
