Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A device for generating control signals, comprising: a support (4) having a recess (28) extending longitudinally along said support; an elongated bar (8) movable longitudinally in said recess; an elongated cylindrical element (16) 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 (15), operable by longitudinal movement of said bar, for producing a first signal; means (20), operable by rotational movement of said cylindrical element independent of and relative to said bar, for producing a second signal; first means (41) coupled to said cylindrical element for imparting to said cylindrical element, in response to a given signal applied to said first means, a first selected force; and second means (40) coupled to said movable bar (8) for imparting to said movable bar, in response to a given signal applied to the second means, a second selected force.
Claim 2
Independent Claim
157 words
A device for generating control signals, comprising: a support (4) having a recess (28) extending longitudinally along said support; an elongated bar (8) movable longitudinally in said recess; an elongated cylindrical element (16) 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 (15), operable by longitudinal movement of said bar, for producing a first signal; means (20), operable by rotational movement of said cylindrical element independent of and relative to said bar, for producing a second signal; first means (41) coupled to said cylindrical element for imparting to said cylindrical element, in response to a given signal applied to said first means, a first selected force; and second means (40) coupled to said movable bar (8) for imparting to said movable bar, in response to a given signal applied to the second means, a second selected force.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein said first selected force comprises a rotary accelerative force.
Claim 4
Dependent Claim
15 words
The device of claim 1 wherein said first selected force comprises a rotary decelerative force.
Claim 5
Dependent Claim
16 words
The device of claim 1 wherein said first selected force imparts a rotary resistance to movement.
Claim 6
Dependent Claim
15 words
The device of claim 1 wherein said second selected force comprises a linear accelerative force.
Claim 7
Dependent Claim
15 words
The device of claim 1 wherein said second selected force comprises a linear decelerative force.
Claim 8
Dependent Claim
15 words
The device of claim 1 wherein said second selected force comprises a resistance to movement.
Claim 9
Dependent Claim
50 words
The control of claim 1 above including transducer means coupled to said support so as to produce a third control signal in response to movement of the cylindrical element and movable bar in a direction approximately perpendicular to the longitudinal movement of said bar in said recess in said support.
Claim 10
Dependent Claim
83 words
A device as set forth in claim 1 including: a first transducer mounted in said support; a second transducer mounted in said support; means operable by the application of a third signal to said first transducer (15) to alter the longitudinal movement or position of said elongated moving bar (8) and rotative cylindrical element (16); and means operable by the application of a fourth signal to said second transducer (21), to alter the rotary movement or position of said rotative cylindrical element (16).
