Multifunction tactile manipulatable control
First Claim
1. A device for generating control signals, comprising:
- a support having a recess extending longitudinally along said support;
an elongated bar movable longitudinally in said recess;
an elongated cylindrical element rotatively mounted in said bar so as to move rotatively with respect to the bar and connected to the bar to move with said bar in said recess;
means, operable by longitudinal movement of said bar, for producing a first signal; and
means, operable by rotational movement of said cylindrical element independent of and relative to said bar, for producing a second signal.

Abstract
A multifunction human digit control includes a rotating cylinder journalled in a movable bar slidable in a groove in a deflectable support track. Rotation of the cylinder by a thumb or finger generates a first motion signal and movement of either or both of the bar and the cylinder by tactile movement, generates a second motion signal, representing, for example, X-axis and Y-axis positions, respectively, of a cursor on a computer screen. Various types of motion detectors or encoders are disclosed to detect the various movements of the bar and cylinder. The mechanism also permits actuation of a switch or other motion detector in a Z-axis by deflection of any one of the bar, the cylinder or portions of the support track with respect to a support structure. In a preferred embodiment, the overall control has its digit-operated tactile surfaces exposed in an aperture contained in a device casing, such as an opening in a computer keyboard or in an instrument housing or control panel.
